摘　　要：针对具有相同结构功能的装备群系统可靠性评估问题,根据任务周期内对装备完好数的要求,合理表示了系统状态转移过程。以部件任务期间状态变化为研究对象,将系统等效表示为多阶段任务系统,即串行k/N(G)系统。在确定系统可行状态过程基础上,分别建立了部件寿命分布在3种不同情形下的系统任务可靠性模型,并分析了备件冷储备方案的影响。为确定系统任务期间备件携带量提供决策支持,最后给出了一个应用实例。In order to evaluate the reliability of equipment group system with the same structure and function, state transition process of system is expressed logically according to the required number of undamaged equipments during mission period. Taking the state change of components during the period as the research object, the system is expressed as phased-mission system equivalently,which is series k/N （G） system. On the basis of determining the feasible state processes,mission reliability models of system are applied respectively in three different situations of component life distribution, and effect of spare cold standby scheme is analyzed. The decision on quantity of spare parts is provided for the period ,finally an example is given.
