ABSTRACT

Preventive maintenance (PM) is an important part of facilities management in many of companies. The goal of a successful PM program is to establish consistent practices designed to improve the performance and safety of the operated equipment. This chapter focuses on the review and summary of PM policies developed and presented in the literature. Many well-known research papers focus on PM models dedicated for optimization of single-unit systems performance. One of the most commonly used PM policies for single-unit systems is an age replacement policy that was developed in the early 1960s. The chapter investigates the PM models for multi-unit systems and reviews maintenance policies for multi-unit systems without component dependence. When there is possibility to identify any occurrence of components dependence in a system, three main types of maintenance policies may be used: group maintenance policy; opportunistic maintenance policy; and cannibalization maintenance.
