摘要: 复杂可修系统可信度建模对保证效能的定量分析至关重要.本文在考虑不同维修状况的基础上,着重对不同任务剖面内相应任务阶段中武器装备可信度进行了深入的定量分析和综合,进而构造出武器装备的可信度矩阵,用于武器装备的效能分析;文中以某地面车辆为例,进一步论证了武器装备可信度矩阵的工程含义,旨在为合理确定一大类武器装备的效能和可信度指标提供理论依据.

Abstract: The dependability analysis of every mission period within every mission profile for repairable system is essential for the quantitative evaluation of system effectiveness and for designing effective system. In this paper, the mission succession probability is chosen as measurement of dependability while both Mission Mileage Between Critical Failure(MMBCF) and Mission Time To Restore Function(MTTRF) are constant. On the basis of various repairable situations, the dependability matrix for effectiveness analysis is established with analytical solutions of mission reliability and mission maintainability. Finally, the establishment of dependability matrix for effective analysis of ground vehicle is given as an engineering application example.The results give helpful and practicable basis for effective analysis of complex engineering systems such as flying vehicles,ground vehicles,automobiles.etc.
