任意结构下可修复备件的配置方案优化

Configuration project optimization for repairable spare parts under discretional structures

合理规划可修备件的配置方案是提高装备维修供应效能的关键,为此,在可修复备件多级库存控制基本理论(multi-echelon theory for recoverable item control,METRIC)的基础上,结合维修参数,建立了任意保障模式下任意结构系统的备件配置优化通用模型。以装备可用度、备件满足率以及保障延误时间为指标,保障费用为约束,采用边际优化算法对模型进行优化计算。通过算例分析了影响备件配置方案的保障性因素,利用多级多层次备件优化工具模型结果进行了验证,证明了该模型的正确性。

Reasonably programming the configuration project for repairable spare parts is critical for impro- ving maintenance supply effectiveness. Based on the multi-echelon theory for recoverable item control （MET- RIC）, considering relative important repair parameters, the universal model of spare parts configuration optimi- zation under the discretional structure equipment and discretional support mode is built. Taking the equipment availability, spare parts fill rate and support delay time as the targets, while the cost is considered as the con- straint, the marginal algorithm is used to the model calculation. According to a given example, the support fac- tors of impacting the spare parts＇ configuration project are analyzed. The calculation result is verified through VMETRIC simulation software, which proves the model＇s correctness.
