摘要

在定量识别多次致命性故障状态的基础上,通过对发生致命性故障事件和修复事件的描述,提出了复杂可修系统可信度计算的一般方法,同时详细地推导致命性故障率和任务修复率为常数时复杂可修系统可信度的计算公式,并且展开讨论了发生多次致命性故障时复杂可修系统可信度的建模问题 ;最后以实例进行了可信度建模的工程化验证。

Abstract

Proposes a new approach to the dependability modeling of complex re?pairable systems by combining quantitative identification to critical failures upon listing situations of mission in succession. According to quantitative expression to critical fail?ures, the mission success probability is chosen as a measure of the dependability of com?plex repairable systems. The approach can provide a numerical solution for mission suc?cess prooability when both the Mission Time Between Critical Failures (MTBCF) and the Mission Time To Restore Function (MTTRF) is constant. Finally, a detailed appli?cation of the approach to dependability modeling during the campaign mobile mission of a ground vehicle is given as an engineering example.
