Research on optimization of preventive maintenance interval decision for vessel equipment

摘要

Optimization of preventive maintenance interval decision for vessel equipment is a multi-attribute decision making problem. But the current studies on the preventive maintenance strategies are mostly with single-objective and based on the assumptions that equipments operating for unlimited time. In this paper, a multi-objective optimization model in limited time is established basing on the existing studies. And the case study of a certain type diesel engine fuel system is used to illustrate the methodology.
