Abstract: This paper presents single and multiple objective deterministic optimization models for opportunistic preventive maintenance of multi-component systems. The single objective model develops an aggregate cost objective function encompassing costs of replacement, fixed costs associated with maintenance interventions and costs of component dismounting whenever the replacement of a given component implies disassembling others. Two multiple objective models are proposed, which enable to explore the trade-offs between minimizing costs vs. the number of maintenance interventions and minimizing costs vs. maximizing the remaining lifetime of components at the end of the planning period. Constraints refer to the requirement of replacing each component before the end of its lifetime and consistency restrictions to allow opportunistic maintenance and dismounting requirements.
