This study aims to select optimal maintenance strategy for components of an electric motor of the National Iranian Oil Refining and Distribution Company. In this regard, a method based on goal programming and analytic hierarchy process is presented. Since increasing the equipment reliability is an important issue, reliability-based maintenance strategies as alternatives are introduced. Furthermore, on one hand, we know that maintenance cost consists of a considerable percentage of production cost; on the other hand, the risk of equipment failure is a main factor on safety personnel. Consequently, two factors of cost and risk of failure are considered as evaluation criteria of maintenance strategies.
