摘要: 为了减少系统非计划停机时间,控制产品质量,提出了以设备可用性为中心的多机维护策略.首先定义三种维护方式,研究其对设备状态的影响机理,从而建立可靠性模型.在对系统进行马尔科夫状态分析的基础上,建立产品质量与系统退化状态之间的关系,构建包含质量损失成本的总成本模型.从实际应用的角度出发,综合考虑设备的可靠性和维护性,以可用性为中心、以总成本最小为目标规划系统的预防性维护策略.实验表明,提出的维护策略可有效地应用于多部件生产系统,且多操作预防性维护方式的效果优于单一操作.

关键词: 退化系统;可用性;预防性维护;马尔科夫状态分析;质量控制

Abstract: In order to reduce system unplanned downtime and control product quality, an availability-centered preventive maintenance strategy of the multi-component production system is proposed. Firstly, three preventive maintenance methods are defined, whose influence on the equipment state is studied so as to establish a reliability model. On the basis of Markov state analysis of the system, the relationship between product quality and system degradation state is established, and the total cost model including quality loss cost is constructed. From the perspective of practical application, the reliability and maintainability of equipment are taken into consideration. Thus, an availability-centered preventive maintenance strategy of the system is planned when the goal is to minimize the total cost. Results indicate that the maintenance strategy proposed can be effectively applied to the multi-component production system, and the effect of the multi-operation preventive maintenance method is better than that of single operation.

Key words: degradation system; availability; preventive maintenance; Markov state analysis; quality control
