Abstract

The heterogeneity of feedstock quality can interfere with the performance deterioration of processing machines, which disturbs the reliability degradation of manufacturing systems. Therefore, system reliability modeling considering feedstock heterogeneity is crucial for remaining useful life (RUL) prediction and preventive maintenance of manufacturing systems. According to the RUL prediction model of manufacturing systems considering feedstock heterogeneity, this study proposes a profit-based importance measure evaluation model and utilizes it as a guide for preventive maintenance decision. The proposed method mainly includes the following steps: (1) analyzing the degradation mechanism of manufacturing systems with feedstock heterogeneity and expounding the reliability and RUL connotation of manufacturing systems, (2) proposing a RUL prediction approach for manufacturing systems based on system reliability model considering feedstock heterogeneity, (3) developing a profit-based importance measure model to evaluate the contribution of a machine’s maintenance action to the profit that the system can increase over its RUL, thus determining the maintenance priority of processing machines and optimizing preventive maintenance strategy. The effectiveness and superior performance of proposed approach is verified through an industrial case study of a servo valve spool manufacturing system.

具有原料异质性的多状态制造系统剩余使用寿命预测与预防性维护方法

原料质量的异质性会干扰加工机械的性能退化，进而影响制造系统的可靠性退化。因此，考虑原料异质性的系统可靠性建模对于制造系统剩余使用寿命预测和预防性维护至关重要。在考虑原料异质性的制造系统RUL预测模型的基础上，提出了基于利润的重要性测度评价模型，并将其作为预防性维修决策的指导。提出的方法主要包括以下步骤：(1)分析了具有原料异质性的制造系统的退化机理，阐述了制造系统的可靠性和RUL内涵；(2)提出了一种基于考虑原料异质性的系统可靠性模型的制造系统RUL预测方法；(3)建立了基于利润的重要性度量模型，以评估机器维护行为对系统在RUL上可增加的利润的贡献；从而确定加工机械的维修优先级，优化预防性维修策略。通过对某伺服阀芯制造系统的工业实例研究，验证了该方法的有效性和优越性能。

期刊介绍： Elsevier publishes Reliability Engineering & System Safety in association with the European Safety and Reliability Association and the Safety Engineering and Risk Analysis Division. The international journal is devoted to developing and applying methods to enhance the safety and reliability of complex technological systems, like nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal normally publishes only articles that involve the analysis of substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a discernable relationship to the solution of such problems. An important aim is to balance academic material and practical applications.
