装备系统可修部件闭环保障系统绩效研究

基于绩效的后勤保障（PBL）正成为军事装备系统一种主导型保障战略。构建一个由备件仓库和部件修理车间组成的装备系统可修部件闭环保障系统。推导出备件库存水平状态稳态概率分布，获得如可用度等几个重要的保障绩效度量指标。采用数值仿真技术考察系统参数在平时与战时环境下对保障绩效的影响。结果表明，初始备件库存水平对系统可用度影响较小且随着故障强度的增加影响程度减弱，而修复能力对系统可用度影响显著。

Performances of repairable parts closed-loop support system for equipment systems

Performance-Based Logistics（PBL）is becoming a dominant support strategy for military equipment systems. This paper sets up a closed-loop support system which consists of a spare parts warehouse and a repair workshop. The steady-state probability distribution of spare part inventory level is derived and furthermore several important perfor-mance measures such as availability are obtained. The effects of system parameters on support performances under peace or war environments are considered by numerical analysis. The results show that the base spare parts inventory level has little effect on the system availability and the degree of effect is decreasing as the failure intensity increases. But, the repair intensity has obvious effect on the system availability.
