Studying corporate culture is an up-to-date direction of research, already quite relevant in the modern complex of management sciences. In the 1980s the idea that effective leadership and long- term business success are connected with creating a healthy corporate structure in the company was first put forward in the book “Corporate Cultures: The Rites and Rituals of Corporate Life” by Terence Deal [1]. The same ideas were outlined in the book “Organizational Culture and Leadership” by Edgar Schein [2]. The most comprehensive study of the interrelation between positive corporate culture and performance is considered to be the book “Corporate Culture and Performance” by John Kotter and James Heskett [3].
In the corporate governance theory, there are a number of approaches to defining corporate culture. For example, М. Albert and F. Khedouri [4] define corporate culture in the following way, “Atmosphere or climate in an organization is called its culture. The culture reflects prevailing habits, customs, and reflections in an organization.”
In Howard Schwartz’s and Stanley Davis’ opinion [5], corporate culture is a “complex of convictions and expectations shared by the members of an organization, these convictions, and expectations shape norms which sufficiently determine the behavior of individuals and groups in an organization.”
According to Elliott Jaques [6], сorporate culture is a “way of thinking and mode of action which grew into the habit and became a tradition, is more or less shared by all employees of the enterprise, and which should be learned and at least partly adopted by new staff members to “blend in.”
According to A. Krylov [7], “Corporate culture is a set of a set of ideas, values, generally accepted patterns and norms of behavior typical for a particular organization; the joint experience of the members of an organization, formed in the course of collective activity and expressed in both material and spiritual forms.”
The Asia Pacific region is increasingly perceived as the century’s geopolitical center. With one-third of the world’s population, a significant share of the world’s trade and production, it seems that the weight of this region is going to be highly relevant in the foreseeable future.
Some countries in the Asia-Pacific region are major importers of conventional weapons, including South Korea, Taiwan, Singapore, and Australia. There are also defense industries in the region that are being developed towards a more self- sufficient production, such as the industries in North Korea and China. The growing economy of China, in particular, has facilitated an increase in military spending which provides consistent financial support to their defense industries.
The new data from SIPRI’s Arms Industry Database shows that sales of arms and military services by companies listed in the Top 100 have increased by 47 per cent since 2002 (the year from which comparable data is first available). The database excludes Chinese companies due to the lack of data to make a reliable estimate.
For the first time since 2002, the top five spots in the ranking are held exclusively by arms companies based in the United States: Lockheed Martin, Boeing, Northrop Grumman, Raytheon and General Dynamics. These five companies alone accounted for $148 billion and 35 per cent of total Top 100 arms sales in 2018. Total arms sales of US companies in the ranking amounted to $246 billion, equivalent to 59 per cent of all arms sales by the Top 100. This is an increase of 7.2 per cent compared with 2017.
A key development in the US arms industry in 2018 was the growing trend in consolidations among some of the largest arms producers. For example, two of the top five, Northrop Grumman and General Dynamics, made multibillion-dollar acquisitions in 2018. US companies are preparing for the new arms modernization program that was announced in 2017 by President Trump. Large US companies are merging to be able to produce the new generation of weapon systems and therefore be in a better position to win contracts from the US Government.
The combined arms sales of the 10 Russian companies in the 2018 ranking were $36.2 billion—a marginal decrease of 0.4 per cent on 2017. Their share of total Top 100 arms sales fell from 9.7 per cent in 2017 to 8.6 per cent in 2018. This can be explained by the higher Top 100 total in 2018 due to the substantial growth in the combined arms sales of US and European companies.
Among the 10 Russian companies listed in the Top 100, the trends are mixed: five companies recorded an increase in arms sales, while the other five showed a decrease. Russia’s largest arms producer, Almaz-Antey, was the only Russian company ranked in the top 10 (at 9th position) and accounted for 27 per cent of the total arms sales of Russian companies in the Top 100. Almaz-Antey’s arms sales rose by 18 per cent in 2018, to $9.6 billion [8].
Works of scientists have served as a methodological framework of this research. There are several typologies of corporate cultures, for convenience’s sake, each of them will be represented in a table. Depending on the influence of an organization’s activity on the final result positive and negative corporate cultures are discerned, their salient features are outlined in Table 1 [9].
Positive corporate cultures | Negative corporate cultures |
---|---|
Democratic Person-centered Integrated Stable | Authoritative Function-oriented Disintegrate Unstable |
Positive and negative corporate cultures.
Typologies of cultures can also base on corporate structure flexibility. Corporate culture typology according to Jeffrey Sonnenfeld [10] is outlined in Table 2.
Type of corporate culture | Description |
---|---|
Baseball team | Decisions are made quickly; talent, innovation, and initiative are encouraged. |
Club | This type is characterized by loyalty, devotion and good teamwork. |
Academy | This type is characterized by a focus on the gradual growth of employees. |
Fortress | This type is common for companies, which lost their former positions on the market as a result of wrong decisions or bad adaptation to the external environment changes. |
Corporate culture typology according to Jeffrey Sonnenfeld.
Organizational psychologists and managers use different variants of corporate culture typology. For instance, an Irish expert on organizational psychology Charles Handy identifies the following types of corporate culture [11]:
Power culture
Role culture
Task culture
Person culture.
One of the notable results of a strong corporate culture is low staff turnover thanks to the consensus among the staff on the mission and values of the organization [12].
Another important result is the improvement of the company’s reputation among such stakeholders as shareholders, customers, suppliers, and the government.
Basing on the factors that influence corporate culture formation and development, it is analyzed through the “externalist” approach, where corporate culture establishment strongly depends on the national culture and is closely connected with the external environment, as well as through the “internalist” approach, where corporate culture is shaped in accordance with organizational culture.
The authors tried to study the experience of corporate culture formation in the largest corporations basing on generally accepted international standards. The biggest companies of the MIC were chosen as the research base.
According to the ranking of hundred largest military-industrial companies in the world as of 2016 made by Stockholm International Peace Research Institute in 2019. THE SIPRI TOP 100 ARMS-PRODUCING AND MILITARY SERVICES COMPANIES, 2019. The world’s largest military manufacturers are Lockheed Martin (USA) Boeing (USA), Raytheon (USA), BAE Systems (UK), and Northrop Grumman Corp (USA) according to SIPRI rating (Table 3) [13].
Position in SIPRI ranking | Name of the company | Annual volume of weapon sales, billion US dollars |
---|---|---|
1 | Lockheed Martin (USA) | 47.3 |
2 | Boeing (USA) | 29.2 |
3 | Northrop Grumman Corp (USA) | 23.4 |
4 | Raytheon (USA) | 26.2 |
5 | General Dynamics Corp (USA) | 22.0 |

9 | Almaz-Antey (Russia) | 9.6 |
10 | Thales (France) | 9.5 |
The world’s largest military-industrial companies according to SIPRI ranking [13].
The SIPRI rating does not include Chinese companies, due to lack of data, but indirectly, we can conclude that one of the largest Chinese military-industrial complex companies is the Aviation Industry Corporation of China (AVIC) - a Chinese state-owned company, a manufacturer of aircraft, part of the Chinese military-industrial complex. It is ranked 159 in the Fortune Global 500.
The top 10 also does not include the Japanese corporation Mitsubishi Heavy Industries (MHI) (25th place).
Analyzing the corporate culture tools of the world’s leading military-industrial complex holdings in the USA and Europe Lockheed Martin, Boeing, Raytheon, BAE Systems, Northrop Grumman Corp, Airbus Group, one can see a standardized approach to corporate culture (Table 4).

Lockheed Martin, Boeing, Raytheon, BAE Systems, Northrop Grumman Corp companies have formed a single standard package of regulatory documents: Code of conduct and Anti- corruption policy the main theses of which coincide almost verbatim.
We should also note Raytheon’s Social responsibility report in a single document [14], BAE Systems Corporate responsibility report (2017) [15], Northrop Grumman’s Corporate responsibility report (2017) [16], AVIC Social Responsibility Report 2017 [17] while the rest of the companies post this information on the official website. BAE Systems’ Code of conduct [18] also contains anti-corruption clauses, with a provision that the Code of conduct contains General corporate rules that may be applied in accordance with the local legislation. Northrop Grumman’s standards of business conduct [19] contain anti-corruption standards, and the company has a separate Anti- corruption compliance program.
Airbus [20], MHI [21] have clear instructions for employees on how to behave in the most common typical ethically difficult situations (Table 5).

Lockheed Martin, Boeing, Raytheon, BAE Systems, Northrop Grumman Corp have all demonstrated a pragmatic approach to social policy, i.e. education was singled out as areas of social policy, in fact, creating a personnel reserve of students/schoolchildren, since the likelihood of recruiting young professionals who have already completed training in corporate programs is very high. A similar situation arises with a detailed examination of support programs for servicemen /veterans, they usually consist in professional retraining for civilian specialties of servicemen and veterans leaving the reserve. Because Since servicemen leave for the reserve at a young and middle age, they also form a personnel reserve for corporations, already trained in the necessary specialties. Supporting volunteering is also beneficial for corporations because allows you to unite teams performing noble social tasks, and the bulk of the costs - time, effort, negotiations, organization - lies with the volunteer workers themselves. At the same time, social areas that do not bring direct benefits to corporations are ignored. Features of BAE Systems is that it implements programs of assistance to military personnel and their families in countries that are the main customers - Great Britain, USA, Australia, Kingdom of Saudi Arabia.
The Chinese corporation AVIC in its principles of CSR - citizen of the world, public welfare, one belt has demonstrated its commitment to the policies of the Government and the Communist Party of the PRC, such as.
One belt - One way
Building a welfare society.
This approach to CSR can be easily explained by the status of AVIC as a state company (Table 8).

The mechanisms for implementing ethical policies provided by Lockheed Martin, Boeing, Raytheon are highly effective because require a minimum of implementation costs, the creation of small divisions to resolve ethical issues at the same time removes significant risks from the line and senior management of the company, allows you to get faster feedback and is an additional control mechanism for lower-level managers and personnel, at Airbus these functions are assigned to the legal department (Table 9).

Diagnosing the type of corporate culture of largest military-industrial companies (developed by the authors).
Authority and hierarchy are determined by the specifics of a large company; if we consider holdings belonging to the largest corporations, then these properties are manifested to a greater extent, since The very scale and complexity of large holdings presupposes a hierarchical organizational structure, a unified approach to managing all enterprises of the holding.
At the same time, the specificity of corporate governance balances authoritarianism, adding such elements of democracy as collegiality of the supreme governing body - general meeting of shareholders, collegiality of the Board of Directors, Committees of the Board of Directors, Management Board, the presence of independent control bodies - auditors, auditors, internal control services and bureaus/ethics commissions. The presence of uniform ethical rules for employees and additional rules for managers brings us closer to a democratic corporate culture and the presence of transparent accountability. The most stringent regulation of employee behavior is provided for by Airbus and MHI.
The culture of “High-stakes (we put on our company)” is a high level of risk and extremely slow feedback. This culture includes, as mentioned earlier, enterprises of the defense industry, which are aimed at obtaining the advantages of enterprises with this type of culture: extremely high investment, a solid approach and a long decision-making process, relatively low staff turnover, resilience and long-term prospects.
The type of corporate culture “Academy” is characterized by a focus on the gradual growth of employees who are ready for long-term cooperation with the company. In such companies, the traditions and customs of the company are highly respected. This is especially true for the Boeing Corporation, which shows pride in its more than 100 year history.
This study supports an inference that anti-corruption policy is developed and implemented by the majority of the companies under research.
As a comparison, the largest Russian military-industrial complex companies included in the SIPRI index were selected (Tables 10 and 11).

Anti-corruption mechanisms, such as regulation of receiving gifts and prevention of conflicts of interest are closely integrated with ethical norms and ethical policy mechanisms, almost all companies under research have hotlines and ethics commissions, which deal with both ethical issues and corruption violations (Tables 12–14). It should be noted that an essential gap in both global and national industry leaders is the lack of internal Corporate governance code, the fundamental document reflecting the quality of corporate culture and corporate governance, all the more so as its existence is recommended by the Corporate governance code approved by the Bank of Russia [22]. Another significant drawback is the absence of social reporting. The absence of such a single document is all the more surprising given that all the studied enterprises have a social policy that is implemented in practice.

Studying the ethical policy of Russian companies, we can conclude that companies are guided mainly by the mandatory rules adopted in Russia by the state and society, the emphasis is made on observing human rights, fairness, labor protection, protection of confidential information, prevention of conflicts of interest and fight against corruption, with lack of attention to issues of special rights of minorities and inclusiveness which are relevant in the society of the United States, the EU, the countries of the British Commonwealth.

The Almaz-Antey Air and Space Defense Corporation [23] does not provide internal documents and reports for public access, the information on social and personnel policy is posted on the official website o the corporation. JSC “Russian Helicopters” [24], United Aircraft Corp [25], United Shipbuilding Corp [26] reflect their social policy in their annual reports. JSC “Russian Helicopters” developed the Code of corporate ethics [27], Anti-corruption policy [28]. JSC “Corporation “Tactical Missiles Corp” developed the Anti-corruption regulation and the Basic social policy [29]. JSC “Concern” Almaz-Antey developed Human Resources and Social Policy [30].
In comparison with the reviewed best practices, it was found that insufficient attention is paid to the following corporate culture tools:
Development of corporate documents
Social reporting
Support for minorities
Inclusiveness
Support for volunteering
Support for military personnel and their families
Support for veterans, retirees and reservists
Educational activities for specialized schoolchildren and students
To assess the effectiveness of the mechanisms of corporate culture with the participation of the authors in 2018–19, an analysis of the mechanisms of corporate culture was carried out using the method of expert assessment.
When applying the method of expert assessments, 10 experts were involved, who are middle managers, specialists in large companies. The evaluation criterion is the effectiveness of the implementation of the corporate culture tool. The form of participation of experts is face-to-face, the type of answers is ranging, the main method is the Delphi method (Table 16) [31].

Step 4. Identifying the most promising ways to improve corporate culture.
To identify more accurately the importance of the corporate culture tools and to develop an algorithm for their implementation, an abstract economic model is suggested for consideration. This model determines the qualitative characteristics of the modeled object, which is the modernization of corporate culture. When building the model, the main approaches of the multifactor model are used, namely, the analysis of the individual factors influence separately and as a whole on the modeled object.

The corporate culture tools analyzed by the authors are currently highly recommended for all companies and mandatory for large businesses and companies with public ownership.
Internationally this is regulated by:
The United Nations Convention against Corruption adopted by the UN General Assembly on 31 October 2003, which applies a broadside approach to identifying and preventing corruption risks in both public and private sectors;
The Organization for economic cooperation and development (OECD) Convention on Combating Bribery of Foreign Public Officials in International Business Transactions;
The US Foreign Corrupt Practices Act (FCPA);
The UK Bribery Act 2010, etc.
In Russia, there are the following legislative norms that recommend and require to implement anti-corruption policy and prevent conflicts of interest:
The Federal law of December 25, 2008, N 273-FZ “On Countering Corruption”;
The Corporate governance code approved by the Bank of Russia.
Methodical recommendations of The Federal Agency for State Property Management (Rosimushchestvo) on the organization of risk management and internal control in the field of prevention and combating corruption and on the organization of the Board of Directors work in a joint-stock company;
Anti-Corruption Charter of the Russian Business approved by The Chamber of Commerce and Industry of the Russian Federation.
Today there are three main concepts, on which modern theories of corporate social responsibility are based.
In Russia, large companies and companies with public ownership are guided by the approach to social responsibility, defined by the Concept of long-term socio-economic development of the Russian Federation [37]. There are no binding forms of social reporting, similar to annual financial statements, but the most widely used ones in the world at present are the UN Global Compact, and The Global Reporting Initiative (GRI) [38].
The stability of the Asia-Pacific region is attracting major attention owing to its increasing relevance in the current globalized world. China has been predicted to be a world power in a few decades. The size and progress of the development of its defense industry are one of the most relevant factors influencing the current global arms market and the security stability in the region.
The region’s nations place greater emphasis on foreign sales and exportation of their defense products. However, they face a highly competitive international arms market where a large number of companies compete to sell their products and only the development of niche technologies appears to have greater prospects for generating success.
Most South Korean defense companies have greatly diversified their production into the commercial sector, which may compensate for the above problems of overcapacity and poor economies of scale (and subsequent lack of competitiveness). The Chinese defense companies have similarly, although less significantly, achieved certain diversification of their production [38].
Conversely, Indonesian arms producers remain highly dependent on the state’s procurement programs.
South Korea and Singapore have had unlimited access to modern weapons systems technologies and to the global arms market; China, on the other hand, has been under an arms embargo placed by the U.S.A. and the E.U. since 1989, and Indonesia was under a U.S. arms embargo between 1999 and 2005. In consequence, China relied on dual-use technologies and reverse engineering techniques applied to Russian weapons systems in order to then develop its defense sector, while Indonesia has been unable to develop its defense industrial base until recent years.
The mercantilist approach, in which the state exercises a large amount of control over the defense industry, may lead to extensive investments in the defense industry, lack of competitiveness, and an eventual decrease in the nation’s security; whereas the application of liberal principles, in which there is minimum intervention by the state in the defense sector, may result in more competitive military equipment production and therefore greater security, although may also create certain vulnerability as there is greater dependence on foreign suppliers.
The study substantiates the relevance of the choice of the research object – the largest enterprises of the military-industrial complex, as the political instability in the world, has led to a significant increase in demand for weapons, besides, the military-industrial complex is one of the most important sectors of the economy because its development fosters the expansion in the related industries – metallurgy, electronics engineering, instrument-making, etc. With significant dependence of the industry on internal and external factors corporate culture is becoming increasingly important for the development of corporations in the industry.
The study revealed that introducing such tools as human rights protection policy, anti-corruption policy, fight against discrimination, protection of information and assets, prevention of insider trading is universal in nature and these tools are implemented by the largest corporations in all the countries under research, namely the USA, the EU, the UK, Russia, Asia-Pacific region.
Depending on the calculated rating it is suggested that the companies of the military-industrial complex introduce the corporate culture tools in the following order:
Development of corporate documents (first of all the corporate governance code)
Social reporting. Priority introduction in the short term up to 1 year.
Support for veterans, retirees, and reservists.
Support for militaries and their families. Introduction on a second-priority basis in the medium term from 1 to 3 years.
Support for volunteers.
Training events for profession-oriented schoolchildren and students. Introduction on a third-priority basis in the long- term period from 1 to 3 years.
Support for minorities.
Inclusiveness. The introduction is not recommended.
The implementation of the suggestions given in the article may have the following positive effects for the corporations of the military-industrial complex:
Creating a positive image in the host country and in the countries which are customers of the products.
Establishing a positive image in the eyes of the state customer, for instance, the support for military personnel/veterans creates a positive image in the eyes of the main consumer - the military department.
The development of the Corporate governance code, other important corporate documents, and transparent social reporting can increase credibility in the eyes of prospective shareholders.
Transparent social reporting, training programs for both personnel and future employees who are retiring militaries, students, schoolchildren will contribute to establishing a positive image among the staff.
Reducing, for the company, the risks from corruption losses.
Reducing for the company the risks from illegal/unethical behavior of the employees, as detailing ethical responsibilities,
procedures, training its employees, the company acts in good faith and reasonably.
The research and conclusions presented in this article can be beneficial not only for the enterprises of the military-industrial complex but also for corporations in other industries making adjustments for an industry specificity.

Many engineering design problems require simultaneous optimization of multiple, often competing, objectives. Unlike in single-objective optimization, a multi-objective problem with competing objectives has no single solution. An optimum solution with respect to only one objective may not be acceptable when measured with respect to the other objectives. Multi-objective problems have a number of solutions called the Pareto-optimal set, named after Vilfred Pareto [1], that represent the range of best possible compromises amongst the objectives. Traditional gradient-based optimization algorithms are capable of addressing the multi-objective problems by converting the problem into a single-objective formulation. On the other hand, evolutionary algorithms (EAs)1 are well suited for the multi-objective problems as they can evolve to a set of designs that represent the Pareto frontier in a single run of the algorithm [2, 3]. As a result, EAs often find application to address multi-objective problems. Despite the popularity of these algorithms to solve a wide range of problems, they, like all non-gradient meta-heuristic searches, have issues with computational cost and rate of convergence to the Pareto frontier. After some number of generations, the candidate solutions may begin to exhibit little or no improvement. Modified versions of these algorithms exist which improve the convergence rate [4]. However, hybridizing EAs with an efficient gradient-based algorithm may significantly improve the convergence rate and has demonstrated the ability to solve multi-objective problems more efficiently than the EA alone [3]. Hybridization of an EA with a gradient-based local search algorithm has started to gain popularity owing to its promising capabilities to address the demerits of many optimization algorithms when used independently.
The genetic algorithm (GA) [5] is a class of EA and is a well-known population-based global search algorithm. Apart from its ability to explore the design space, GA is also capable of handling both discrete and continuous type design variables. This makes the GA an ideal choice to address problems that combine both discrete and continuous variables. However, the GA, like other EAs, does not provide any proof of convergence, and the GA cannot directly enforce constraints. Commonly, constraint handling for a GA search uses a penalty approach such that the fitness function reflects the objective function value and accounts for violated constraints. This generally requires the use of penalty multipliers to adjust the “strength” with which the penalty impacts the fitness function and selecting suitable penalty multipliers is often difficult. Further, for multi-objective problems, the different scaling or magnitude of the objectives can complicate selecting appropriate penalty multipliers.
On the other hand, Sequential Quadratic Programming (SQP) [6], is a well-known gradient-based search algorithm that directly handles constraints and provides proof of convergence to local optima using Karush-Kuhn-Tucker (KKT) optimality criteria [7]. Because SQP uses gradient information, it is a computationally efficient search algorithm. However, SQP cannot handle discrete design variables or discontinuous functions and has difficulty with multi-modal functions. Therefore, both of these (GA and SQP) well-known optimization algorithms have their own pros and cons that limit their individual applicability to fully address constrained multi-objective problems that combine both continuous and discrete type design variables. Combining the GA with SQP creates a hybrid approach that improves the overall optimization process for constrained mixed-discrete nonlinear programming problems (MDNLP).
The chapter presents a combination of the two-branch tournament GA for multi-objective problems with an SQP-based local search implementation of the goal attainment problem formulation allowing an improved information sharing between the two algorithms. To the best of the authors’ knowledge, there exists no work that emphasizes the process of hybridization combining an N-branch tournament selection GA with the goal attainment formulation as the local search in a compatible manner and then demonstrates application of the approach to solve a hard-to-solve constrained multi-objective, mixed-discrete nonlinear optimization problem. Later in the chapter, the hybrid approach is applied to solve a three-bar truss problem, a ten-bar truss problem, and a greener aircraft design optimization problem – all representatives of constrained multi-objective, mixed-discrete nonlinear programming problem. The truss problems have basis in test problems for structural optimization, and the motivation to select a greener aircraft design optimization problem arises from the increased concern about the environmental impact of the growing air transportation system.
The ability of the EAs to evolve to a Pareto-frontier as the generation progresses makes them an ideal choice for several multi-objective optimization problems. Vector Evaluated GA (VEGA), proposed by Schaffer [8] back in 1985, is one of the earlier versions of multi-objective GA. Several multi-objective EAs are developed since then including Multi-Objective Genetic Algorithm (MOGA) [9], Strength Pareto Evolutionary Algorithm [10], Non-dominated Sorted Genetic Algorithm (NSGA) [11] to mention a few popular ones.
Coello [2, 12] has conducted comprehensive literature surveys of various evolutionary multi-objective techniques. Konak et al. [13] compared various multi-objective optimization algorithms and provides a set of guidelines to follow while developing a multi-objective algorithm. Their effort primarily lies in guiding researchers with very little background in MOGA and making them familiar with the ideas and approaches of multi-objective optimization.
One such multi-objective algorithm named Non-dominated Sorting Genetic Algorithm (NSGA), developed by Srinivas and Dev [11] – arguably one of the most widely used multi-objective EAs – uses the concept of non-dominated sets originally proposed by Goldberg in his book on Genetic Algorithm and Machine Learning [14]. The NSGA approach maintains sets of non-dominated individuals, with the first set of individuals not dominated by any other individuals in the population. The second set finds the new set of non-dominated individuals after excluding the individuals from the first set. This step continues until all the individuals in the population are categorized inside the non-dominated sets.
A majority of these multi-objective algorithms, in some form, require an assignment of a scalar measure of a fitness value to the individuals in the population. As an example, MOGA [9] and NSGA [11] assign a fitness value based on a ranking scheme depending on the individual’s levels of domination. The two-branch tournament selection genetic algorithm presented by Crossley et al. [15] uses a tournament selection scheme that chooses parents considering both the objectives directly in the fitness functions. The individuals are evaluated based on their fitness across both the objectives. The overall process remains the same as that of a traditional GA. However, the only difference appears in the tournament selection operator. During the tournament selection step, the algorithm selects 50% of the parents based on the fitness value associated with the first objective, that is, the individuals are evaluated solely with respect to the first objective without consideration of the other objective. These selected parents are by nature strong in objective 1, or
The hybrid approach, presented in this chapter, uses this two-branch tournament selection GA as the global search optimizer and combines with a gradient-based approach to refine the search using a novel information sharing concept in the process of hybridization. The unique tournament selection strategy of the two-branch tournament GA allows to understand the underlying trait of the parents, i.e., if they are
Another challenge with multi-objective EAs is their ability to enforce constraints. Unlike gradient-based methods, which use constraint gradient information to guide the search in the feasible direction, no such constraint gradient is available for EAs. There have been several efforts to handle the constraints for EAs; however, not all of these methods strictly or directly enforce the problem constraints. The penalty function approach is arguably the most widely known of the various approaches to handle constraints in EAs. Assuming a minimization problem, this approach adds a penalty to the objective function when constraints are violated [14].
Another simple approach includes ignoring any infeasible design solution; because this does not differentiate between constraints that are close to the constraint boundaries and those that are far apart, this constraint handling method is inefficient.
Binh and Korn [16] suggested a method to assign fitness to individuals based on combining both the objective function vector as well as the degree to which the individual violates the constraint. Infeasible individuals are categorized into different classes based on how close or how far they are to the constraints boundaries.
Fonseca and Fleming [17] proposed a priority-based constraint handling strategy where search is first driven for feasibility followed by optimality by assigning high priority to constraints and low priority to objective functions. Although there are various techniques to “handle” constraints in EAs, “enforcing” them in a robust way is still an open issue. This is another motivation to pursue the hybrid approach that leverages the efficacy of gradient-based search to enforce the problem constraints.
Further, these population-based searches have issues with computational cost and rate of convergence to the Pareto frontier. After some number of generations, the candidate solutions may begin to exhibit little or no improvement. Modified versions of the algorithms work to improve the convergence rate [4, 18]; however, hybridizing EAs or GAs with an efficient gradient-based algorithm can significantly improve the convergence rate, thereby reducing the computational cost. Hybridization of an EA or GA with a gradient-based local search algorithm is not new. There are numerous references demonstrating how hybridization may improve the quality of the search for both single objective and multi-objective problem formulations; these include, but are not limited to, those appearing in [3, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32]. The local search can be considered as the local learning that takes place in an individual throughout its lifespan. Some of the approaches apply the local search to the final non-dominated set, while some techniques apply local search to all or many individuals of the population as the generation progresses.
The effort here extends the previous effort by Lehner and Crossley [27] to include a multi-objective formulation and combine the advantage of the hybrid approach with an novel information sharing technique between the global and the local search. The two-branch tournament selection GA algorithm globally explores the design space handling both discrete and continuous type variables, while the gradient-based approach sees only the continuous variables in a goal attainment formulation and seeks to efficiently refine the population based on the information passed on by the top-level GA while enforcing all the problem constraints.
The hybrid approach presented in this chapter combines the two-branch tournament GA (see Figure 1) for the global search [15] and the goal attainment SQP algorithm provided in the function

The top level of the problem, which the GA sees as its optimization problem, is a bound constrained (i.e., only side constraints on the continuous design variables) multi-objective minimization problem that uses the two-branch tournament selection technique with some modification to include the local search. This level includes both discrete and continuous design variables of the original problem. The continuous variables in this level,

Although the approach seems robust in enforcing constraints via goal attainment formulation, there may be instances when no feasible solution exists to the goal attainment formulation for a given set of discrete variables. In such cases, the local search will not be able to return a feasible solution and the fitness function receives a severe penalty in the GA-level in an effort to discard such discrete design choices from the population. This severe penalty has some resemblance to the approach of ignoring infeasible designs that was criticised above; however, because the situation where no locally-feasible design exists results from a specific combination of discrete variables, there is no analog to having a “nearly feasible” design with a slightly violated constraint. Severely penalizing such infeasible designs for certain combinations of discrete variable choices, in this context, is appropriate.
To demonstrate the efficacy of the hybrid approach in solving constrained multi-objective MDNLP problems, we solve three different engineering test problems with varying difficulties - a three-bar truss, a ten-bar truss, and greener aircraft design problem.
For the three-bar truss problem (see Figure 5), the problem formulation includes the objectives of minimizing the weight of the truss and minimizing the deflection of the free node. The deflection of a node is calculated as the resultant of the deflections in both the x and y directions. The problem consists of six design variables, of which three are continuous and three are discrete. The continuous variables describe the cross-sectional area of the three bars while the discrete variables describe the material selection properties of these bars. The details of the continuous design variables and their design bounds appear in Table 1. For this problem, four discrete material selection choices are available for each element and include aluminum, titanium, steel, and nickel options. The yield stress for every bar acts as a constraint for the problem (total three constraints), not allowing the stress in the bar to go beyond that upper limit. References [35, 36] provide more details about the three-bar truss problem. For the hybrid approach, the GA population is limited to 8 individuals while setting the upper limit for the number of generations to 50. The probability of crossover is set to 0.5 and the mutation rate is fixed at 0.005. The continuous and discrete variables uses 8 and 2 bits respectively in the Gray-coded binary scheme.

Continuous variables for three-bar truss problem.
The resulting Pareto frontier for the three-bar truss problem appears in Figure 6(a). The plot shows the Pareto frontier has a good spread, leading to a total of 248 non-dominated points as solutions to the optimization problem. The visible trend in the non-dominated design set indicates that as the weight of the three bar truss system increases, they are accompanied by similar increases in the cross-sectional area of the bars with the material selection choice gradually shifting to steel for all the three bars. Aluminum or nickel never appeared as the material selection choice in the first two bars. The designs visible in the top left corner of the Pareto front in Figure 6(a) correspond to high displacement and low weight designs. The separated cluster of points (six designs) visible at the bottom right corner of the Pareto frontier corresponds to low displacement and high weight designs, with the maximum weight design having a material combination of all steel bars.

(b) Comparison of Pareto frontier obtained using the hybrid approach, a weighted sum approach and the original two-branch tournament GA approach.
For the three-bar truss problem, only 64 possible combinations of discrete design variables exist. Hence, it is possible to perform a complete enumeration of the discrete design space and get a sense of the shape of the true Pareto front and help assess the performance of the hybrid approach. This led the authors to compare the hybrid approach (and the original two-branch tournament selection GA2) with a gradient-based weighted sum approach for this three-bar truss problem. The weighted sum approach converts the multi-objective problem formulation into a single objective problem by assigning weights to both the objectives and solves the single objective problem with the gradient-based approach using MATLAB’s
First, the objectives are normalized using the utopia point. Next, objective 1 is assigned a weight
Figure 7 compares how the Pareto frontier evolved with generations using the original two-branch tournament GA and the proposed hybrid approach. As expected, without the local search feature, the original two-branch tournament selection GA shows distinct improvement in both the quality and the spread of the Pareto front as the generation progresses. That is, the black diamonds (non-dominated set after second generation) are replaced with better non-dominated designs as the generation progresses. However, in the hybrid case, we start to see the shape of the final Pareto front immediately after the second generation. As the generation progresses further, more points get added to the list of non-dominated designs. This is due to the multi-start approach where the top-level GA populates various possible combinations of the discrete material selection choices and the local gradient-based search then improves these designs by varying the continuous design variables. The hybrid approach is able to rapidly get to the final Pareto front at the expense of increased number of function evaluations needed by the gradient-based local search.

Next, the hybrid approach solves a more difficult and challenging version of the three-bar truss problem – a ten-bar truss. Similar to the three-bar truss problem, the ten-bar truss has the competing objectives that include minimizing the weight of the ten-bar truss system and minimizing the resultant displacement of any of the free nodes. The displacement is taken as the absolute of the maximum calculated displacement among all the bar elements. This problem consists of twenty design variables – ten continuous type and ten discrete type. The continuous variables describe the cross-sectional diameters of the ten bars, ranging from 0.1 cm2 to 40 cm2, while the discrete variables specify the material selection properties of these bars. Like the three-bar problem, the four discrete material choices available for each bar include aluminum, titanium, steel, and nickel. However, this problem has over one million possible combinations of the discrete choices (
Figure 8(a) compares the Pareto front obtained using the hybrid approach after 20 GA generations with the Pareto frontier obtained using the two-branch tournament selection GA after 100 generations. The figure shows both the approaches performed well for this problem with the two-branch tournament selection GA resulting a better spread in the low weight/high displacement region of the objective space, whereas the hybrid GA has a better spread in the low displacement/high weight region. Figure 8(b) shows how the non-dominated set evolved as the generation progresses using the hybrid approach. We see a similar trend as that of the three-bar truss problem. That is, there is not much significant change in the final shape of the Pareto front other than the increase in the number of non-dominated designs as the generation progresses. However, this time there is slight improvement in the quality of the Pareto front (the red non-dominated set obtained after generation 20 is slightly better than the blue or the black non-dominated designs obtained at generation 5 and 2 respectively).
Ten bar truss problem results. (a) Comparison between the original two-branch tournament GA (after 100 GA generation) and the hybrid approach (after 20 GA generations) for the 10 bar truss problem. (b) Evolution of non-dominated set as the generation progresses for the 10 bar truss problem using the hybrid approach.
For the three-bar example, a majority of the improvements across the objective space are due to the gradient-based local search’s ability to obtain designs with better cross-sectional area. With only 64 possible material selection combinations, there are not many discrete material selection options to explore. On the other hand, for the ten-bar truss problem, a vast majority of the improvement is due to the ability of the GA to find a better material selection combination rather than fine-tuning the cross sectional variables. It is not possible to seek further improvement in the Pareto front just by varying the continuous variables, so the local search saturates as appear in the case of black (diamonds) and blue (squares) non-dominated designs. After few more GA iterations, the algorithm is able to find better combinations of material selection that lead to further improvement in the Pareto front (red dots).
The third application problem solved using the hybrid approach is the greener aircraft design problem. Here, a “greener” aircraft design problem provides an example to demonstrate the efficacy of the hybrid algorithm and its ability to solve such MDNLP problems. The intent is to find aircraft designs that represent the best possible trade-offs among performance, economics, and environmental metrics which essentially makes this a multi-objective problem. Further, with the inclusion of discrete technologies, the problem becomes MDNLP in nature.
The aircraft design optimization problem employs the NASA sizing code FLOPS [37] to evaluate discrete design configurations and perform the sizing and performance calculations of the candidate aircraft designs. The sizing code accepts both continuous and discrete design variables as input and returns the aircraft gross weight along with environmental metrics (fuel weight, which corresponds to CO2 emissions, and NO
The problem includes ten continuous variables that define the wing and the engine parameters of the aircraft. The details of these continuous design variables and their design bounds appear in Table 2.

Continuous variables for aircraft design problem.
This aircraft design optimization study models three types of discrete technologies. Table 3 lists the set of discrete technologies considered in this study. To model composite material selection choice on various aircraft components, the approach here uses a binary variable for each of the aircraft components that includes wing, fuselage, tail, and nacelle. A value of one represents composites being present while a value of zero represents no composite materials in that structure. The second discrete variable includes the eight possible combinations of the location and the number of engines. Lastly, eight combinations of laminar flow technologies are included for this problem, depending on whether it is natural laminar flow (NLF) or hybrid laminar flow control (HLFC) technology and the number of components on which it is applied (as listed in Table 3). References [38, 39, 40] describe the various discrete technologies used in this study in further detail.

Wing | Fuselage | Nacelle | Tail | ||

The problem also has four constraints that appear in Table 4. The constraints ensure that the design solution meets the desired field length criteria, has sufficient ground clearance, and sets a maximum limit on the amount of allowable fuel carrying space in the fuselage.

Problem constraints.
The aircraft design optimization problem considers two different pairs of competing objectives. The first pair involves simultaneous minimization of the aircraft fuel weight (index of CO2 emissions) and the total operating cost of the aircraft, and the second pair involves minimizing the NO
Figure 9 shows the set of 24 non-dominated designs for the competing objective pair – aircraft fuel weight and total operating cost. The aircraft fuel weight, analogous to fuel burn, is directly related to the amount of CO2 produced during the trip. The Pareto frontier consists of designs employing combinations of composite structures, eight different engine position(s), and eight different laminar flow technologies, modeled as a part of the greener technology approaches described in the previous section.
The non-dominated set for objective pair – aircraft fuel weight (index for CO2 production) and the total operating cost.
The design point ND1 (for Non-Dominated design number 1) in Figure 9 corresponds to highest total operating cost (also lowest fuel weight) and makes use of NLF technology on the wing and HLFC technology on the nacelles and tail, along with two wing-mounted engines. This design also features composite wings, fuselage, and nacelles. The use of composite structures leads to a decrease in the fuel consumption (due to the reduction in aircraft empty weight) at the expense of increased total operating cost (due to increase in the manufacturing and maintenance costs associated with composite materials). The design with the lowest total operating cost (ND24) makes use of NLF technology on the wing and HLFC technology on the nacelles and tail, along with two wing-mounted engines as well. But, this design has no composite components and, hence, has the lowest total operating cost according to the models used in this study.
All the non-dominated designs employ NLF technology on the wings and HLFC technology on both the nacelle and tail, along with two wing-mounted engine configuration. The laminar flow technologies tend to reduce the skin friction drag of the aircraft, making the design more aerodynamically efficient, and reducing its fuel consumption for a given mission range. All the non-dominated designs employ these technologies in various forms (NLF or HLFC) to reduce fuel burn, depicting the importance of employing these technologies in near future “greener” aircraft design.
An interesting region in the Pareto frontier from an airline’s standpoint would be near the points ND1 and ND3 (or ND2), where a substantial decrease in total operating cost is possible for a marginal increase in the aircraft fuel weight (index of CO2 production per trip). Considering non-dominated designs ND1 and ND3, a nearly 1% reduction in total operating cost is possible to achieve for only a 0.6% increase in the total fuel weight needed for the mission, as one move from ND1 to ND3. Similar trends for the objective pair in consideration are also observed for designs ND9, ND10, and ND11.

The non-dominated set for objective pair – NOX emissions versus total operating cost.
The design with minimum NO
An interesting region from the airline’s point of view is the near the points ND2, ND3, ND4 and ND5, where a nearly vertical portion is visible in the top left portion of the Pareto frontier (refer to Figure 10). Moving from left to right in this region, a substantial decrease in total operating cost is possible for a marginal increase in the NO
Given there is some degree of randomness associated with the genetic operations in the GA, subsequent runs of the hybrid GA for the two objective pairs find a slightly different number of non-dominated designs points. However, the basic trait of the Pareto frontier, in terms of the discrete choices, did not alter; only the density of points in the Pareto frontier varied with different runs.
This chapter describes a hybrid multi-objective algorithm that makes use of an efficient gradient-based SQP algorithm for fitness evaluation inside a GA in a learning approach. The combination allows the GA to evolve a population of designs in the direction of the Pareto frontier while the SQP algorithm enforces constraints, eliminating the need for penalty multipliers or other special constraint handling methods and refines the values of the continuous design variables. The selective parent mixing and unique sets of goal point assignment to the individual lead to a distinct improvement in convergence and the quality of the Pareto frontier from a previous variation of this approach. When applied to various constrained MDNLP engineering design problems, the hybrid algorithm shows the ability to identify promising designs.
Although the ability of the hybrid approach to solve difficult constrained MDNLP problems is demonstrated in this chapter, the methodology relies heavily on the constraint enforcing ability and efficient searching of the continuous design space via the local gradient-based SQP algorithm that requires some estimates (either numerically or analytically) of the gradients of the objectives and the constraints with respect to the continuous design variables. A major advantage of a gradient-based approach besides being able to enforce the problem constraints (hence, the motivation to hybridize) is that the computational cost needed to compute the gradients is nearly independent of the number of design variables [41] when using adjoint-based methods to estimate the derivatives. This allows the gradient-based approach to efficiently solve problems with a very large number of design variables. However, if the objectives are encapsulated in a black-box function and are computationally very expensive to evaluate, then it may not be possible to directly implement a gradient-based search and may require a surrogate-based design optimization approach [40, 42, 43].

deposition (CVD) is a technique for the fabrication of thin films of polymeric materials, which has successfully overcome some of the issues faced by wet chemical fabrication and other deposition methods. There are many hybrid techniques, which arise from CVD and are constantly evolving in order to modify the properties of the fabricated thin films. Amongst them, plasma enhanced chemical vapor deposition (PECVD) is a technique that can extend the applicability of the method for various precursors, reactive organic and inorganic materials as well as inert materials. Organic/inorganic monomers, which are used as precursors in the PECVD technique, undergo disintegration and radical polymerization while exposed to a high-energy plasma stream, followed by thin film deposition. In this chapter, we have provided a summary of the history, various characteristics as well as the main applications of PECVD. By demonstrating the advantages and disadvantages of PECVD, we have provided a comparison of this technique with other techniques. PECVD, like any other techniques, still suffers from some restrictions, such as selection of appropriate monomers, or suitable inlet instrument. However, the remarkable properties of this technique and variety of possible applications make it an area of interest for researchers, and offers potential for many future developments.",book:{id:"5211",slug:"chemical-vapor-deposition-recent-advances-and-applications-in-optical-solar-cells-and-solid-state-devices",title:"Chemical Vapor Deposition",fullTitle:"Chemical Vapor Deposition - Recent Advances and Applications in Optical, Solar Cells and Solid State Devices"},signatures:"Yasaman Hamedani, Prathyushakrishna Macha, Timothy J.

If its use complies with the five specifications including synthesis pathway, crystallographic phase, purity, amount and innocuousness, all other parameters are not defined and were hardly documented. However, in the last 3 years, two studies have deeply characterized food-grade TiO2 and converged to the fact that the size distribution of food-grade TiO2 spans over the nanoparticle range (<100 nm) and the surface is not pure TiO2 but covered by phosphate and eventually silicon species or aluminium species, which modify the surface chemistry of these particles. Until now, this material was considered as safe. However, the toxicological studies later to the last re-evaluation by the European Food Safety Agency reveal some concerns due to the ability of TiO2 particles to alter the intestinal barrier.
