摘要:

合适的预防性维修在一定程度上能提高设备可靠性,延长设备寿命.针对目前预防性维修策略决策粒度过大且鲜有考虑预防性维修对不同类型故障维修效果的差异性等问题,研究了元动作单元的不完全顺序预防性维修策略.以元动作单元为研究载体,将故障分为损伤类故障和本质疲劳类故障,基于广义几何过程(GGP)建立了考虑维修效果差异性的顺序预防性维修优化模型,分析了维修成本等因数对最优维修成本率以及最优维修策略的影响.研究表明:不考虑预防性维修效果的差异性会低估总体的维修成本率.同时,各类型维修成本、故障比例因子以及预防性维修效果参数都对维修策略的制定有显著影响.该研究对制定元动作单元顺序预防性维修策略,减少其维修成本具有一定的指导作用.

Abstract:

Proper preventive maintenance can improve equipment reliability and prolong equipment life to a certain extent. Aimed at the problems that the decision granularity of the current preventive maintenance strategy is too large and the maintenance effect of preventive maintenance on different types of failures is rarely considered, the imperfect sequential preventive maintenance strategy of the meta-action unit is studied. Taking the meta-action unit as the research carrier, the failures are divided into damage failure and essential fatigue failure according to the difference of preventive maintenance effect. Based on the generalized geometric process, a sequential preventive maintenance optimization model is established. The research shows that the overall maintenance cost rate will be underestimated without considering the differences in preventive maintenance effectiveness. At the same time, various types of maintenance costs, the proportion factor of damage-type failures and intrinsic fatigue-type failures, and the preventive maintenance effect parameter have a significant influence on the formulation of maintenance strategy. This research has a certain guiding role in formulating the sequential preventive maintenance strategy of meta-action unit and reducing its maintenance cost.

Key words: preventive maintenance, meta-action unit, generalized geometric process(GGP), sequential maintenance, imperfect maintenance
