有限备件条件下系统任务成功概率的求解算法

A Mathematical Algorithm for Mission Availability of System Given Limited Spares

给出部件失效服从负指数分布的任意结构系统在有限备件组合方案下的任务成功概率求解算法,该 算法可以在已知系统结构函数、系统初始状态以及工作时间的条件下,计算给定备件组合方案后系统完成任 务的成功概率,为维修保障指挥提供决策依据。

This paper gives a mathematical algorithm for mission availability of system with various configurations given limited spares where component lifetime follows exponential distribution. When the system configuration, system initial status and the time interval of mission are given, this algorithm can calculate the mission availability of different spare support schemes.
