| 摘 要： | 对复杂系统提出了采用成组维修策略.根据成组维修的特点,分析了复杂系统维修费用构成和系统利用率,在此基础上,以故障风险为约束,以系统总体维修费用的最小化、系统利用率最大化为目标,建立了复杂系统成组维修策略的优化模型.最后采用遗传算法,以某民用飞机的空调系统维修为例对模型的有效性进行了验证.

| Abstract: | Maintenance of complex systems is different from maintenance of individual units,because there are economic and failure dependence between units in the system.The optimal maintenance intervals of the units are not necessarily optimal in view of the entire system.For this reason,group preventive maintenance is presented for complex systems.First,maintenance cost and availability are analyzed.The optimal group preventive maintenance model is then proposed for complex systems.Subject to hazard,the model minimizes maintenance cost and maximizes availability.Finally,an air conditioning system is presented as an example in the case study,and the result shows effectiveness of the model. |
