About the book
Industrial and commercial systems always try to increase the reliability of their production process or service. In this context, maintenance performs a fundamental role in order to reach high availability and reliability concerning their equipment and services. Maintenance can be understood as the action on the equipment, system or installations based on the previous knowledge about the operating condition or performance, obtained by means of parameters previously determined.
Due to the new technologies and strategies from other areas which can be applied in the maintenance process, the systems have on-line monitoring of behavior and performance. Monitoring condition of the systems is a continuous evaluation process of the health of equipment during all its useful life. The main function of a monitoring system is to recognize development of failures in an initial state. For the maintenance department, each failure must be detected as soon as possible in order to promote a programmed stop of the machine. The process of continuous monitoring of a condition of vital equipment for the production process brings significant benefits for the company. The main benefits are bigger efficiency of the productive process, reduction of the losses for not-programmed stops, increase of the useful life of the equipment, and built history of failures. A continuous monitoring system must observe parameters that give trustworthy information to the maintenance team for decision-making.
Therefore, it can be noticed that this area of technology demands knowledge on the functioning of equipment, machines, instrumentation, microprocessors, processing of the signal, analysis of materials, chemical analysis, analysis of vibrations, and so on.
