Preventive Maintenance

One of the main objectives of this chapter is to introduce some basic concepts related to preventive maintenance. This is a crucial topic, as the ever-increasing complexity of automated systems has been accompanied by a growing demand for the availability and security of industrial installations. It is indeed financially futile to design installations that frequently break down and pose a danger to people, the environment, and property. Increased availability can be achieved through improved reliability of functional units, as well as the implementation of a maintenance strategy tailored to the specific installation. Maintenance refers to all actions intended to maintain or restore an asset to a specified condition, perform a required function, or ensure a determined service.
