不完全覆盖的多阶段系统可靠性集成分析

Integrated Analysis of Phased-Mission System Reliability with Imperfect Coverage

针对多阶段任务系统的可靠性分析,提出系统分解方法.在不完全覆盖条件下,综合两种方法:静态的IGPMS-CPR算法和动态的覆盖模型结合马尔科夫链的一体化方法,侧重研究静态子系统连接动态子系统的特殊对应关系并提出相应简便算法.此方法有效地集成多种成熟的分析方法,通过案例分析阐述其低运算量和容易实施的特点.

Accounting for reliability analysis of phased-mission systems, a new modularization technique is presented. Further considering imperfect coverage, a new algorithm incorporates static IGPMS-CPR approach and a dynamic method integrating imperfect coverage model with Markov chain. After special dependencies from static subsystems to dynamic subsystems are researched, the algorithm based and easy solution is obtained. The solution implements a synthesis of the approaches into a single methodology which advantages of the low computational complexity and easy implementation are showed using an example.
