This paper deals with the concept of Maintenance Free Operating Period (MFOP). This MFOP is defined as a period of operation during which the system should be able with a given level of confidence to carry out all its assigned missions without system faults or performance limitations. The idea is to ensure with a given level of confidence that no unscheduled repair operation will be required during each defined period of operation. The main objective of this article is to present an approach to optimize maintenance strategy and to evaluate the system design based on MFOP concept. In this paper, the system design includes the problems of available state information and reliability properties of components which strongly influence the maintenance policy accuracy. An example based on a sub-system of commercial heavy vehicle is introduced to illustrate the proposed methodology.
