| 摘 要： | 针对舰船编队在航无补给的情况,对经典可修复备件多级管理(multi-echelon technology for recoverable item control,METRIC)模型进行了扩展,建立了舰船出航期间设备冗余和外场更换件冗余系统任务成功概率评估模型及备件优化模型。针对任务期间舰船设备和外场更换件最小工作数量随时间变化、编队任务成功概率难求的问题,采用超几何分布和二项分布结合的方法求取装备的瞬时可用度,进而求得舰船编队的任务成功概率。以任务成功概率为优化目标,备件总费用为约束条件,基于边际算法计算了备件方案。通过实例分析了在航编队任务成功概率随时间的变化曲线,曲线变化趋势与实际情况相符。

| Abstract: | When the fleet executes short term mission, it has no charge in halfway. A two stage repair model according the multi-echelon technology for recoverable item control (METRIC) model is built to solve this problem, which can assess the probability of success for mission and optimize spare parts scheme. The combination of binomial distribution and hypergeometric distribution is used to solve the problem, but the probability of success is difficult to solve when the redundancy numbers of component and line replaceable unit (LRU) change with time. Finally, an example which has got a spare parts plan throw marginal algorithm optimization is given, and it analyzes the mission success probability of the fleet on different stages. The result is consistent with the reality. |
