| 摘 要： | 为研究水下生产系统关键设备预防性维修策略制定及优化问题,通过建立以威布尔分布为模型的可靠性衰退趋势模型,构建以可靠性和经济性为指标的多组件系统的预防性维修策略多目标优化模型,并在可靠性预测数学模型的基础上,对水下生产系统中实际生产中各组件全寿期内的维修成本进行计算,并对三种维修策略下的维修成本与可靠性进行分析与讨论。研究结果表明,采用基于功能的多组件成组维修策略可以在对可靠性水平较小的牺牲下,有效降低维修成本,同时有效避免传统成组维修策略中欠维修与过维修的现象发生。

| Abstract: | In order to develop and optimize the preventive maintenance strategy for key equipment of underwater production system, the reliability degraded trend model based on Weibull distribution is built. A multi-objective optimization model for the preventive maintenance strategy of multi-component system is established. Based on the mathematical model of reliability prediction, the total lifetime maintenance cost of each component in underwater production system is calculated, and the maintenance cost under three maintenance strategies is analyzed and discussed. The results show that the multi-component group maintenance strategy based on function can effectively reduce the maintenance cost under the sacrifice of low reliability level, and effectively avoid the phenomenon of under-maintenance and over-maintenance in the traditional group maintenance strategy.. |
