摘要:

预防维修由于可以及时消除潜在故障隐患,有效提高系统运行可靠性,在工业界和学术界正受到广泛关注和应用。然而,随着维修次数的不断增加,工程实际中的可修系统会逐渐出现“修理疲劳”现象,即维修活动对提高设备寿命和降低系统故障率正向影响的边际贡献会逐渐减小。本文考虑工程实际中设备的“修理疲劳”现象,基于动态故障率增加因子和役龄回退因子建立周期不完美维修决策模型和序贯不完美维修决策模型,并在更新报酬定理基础上对预防维修模型的最优策略进行优化。案例证明了不考虑 “修理疲劳”现象往往会导致过度维修,不仅浪费维修资源,还可能造成备件订购的延迟。本文分析了不同维修成本对最优周期不完美维修策略和序贯不完美维修策略的影响,为工业企业更好地制定维修决策提供理论依据和技术支撑。

Abstract:

Preventive maintenance is receiving widely attention and application both in industry and academia because it can eliminate potential faults in time and effectively improve system reliability. However, with the continuous increase of maintenance numbers, repairable systems in engineering practice gradually show long-term “repair fatigue”. That is, the marginal contribution of maintenance activities to the positive impact of improving equipment life and improving system failure rate will gradually decrease. Considering the phenomenon of “repair fatigue” of equipment in engineering practice, periodical imperfect maintenance models and sequential imperfect maintenance models are established based on dynamic failure rate improvement factor and age reduction factor, and subsequently, the optimal policies of the maintenance models are optimized according to the renewal reward theorem. Numerical experiments demonstrate that ignoring the repair fatigue will lead to excessive maintenance, not only wasting maintenance resources but also delaying the ordering of spare parts. In addition, the effects of various maintenance costs on the optimal decisions of periodic imperfect maintenance strategy and sequential imperfect maintenance strategy are analyzed, providing theoretical and technical support for industrial enterprises to better schedule maintenance activities.

Key words: preventive maintenance (PM), imperfect maintenance, repair fatigue, renewal reward theorem, adjustment factor
