摘　　要：任务可信性是衡量维修保障系统能力的重要指标。研究了任务期间允许换件维修和备件补充时作战单元在非连续工作条件下的任务可信度。利用马尔可夫过程分析了部件系统的状态转移过程,以定长时间内部件系统在正常状态停留时间的分布函数作为其任务可信度,通过全概率分解方法对可信度进行了求解。依据任务期间装备与部件系统、最小任务单元与装备、作战单元与最小任务单元之间的任务可靠性关系,建立了单台装备、最小任务单元、作战单元的任务可信性模型。实例分析结果表明该模型有效可行。Mission dependability is an important index to estimate the capability of maintenance support system.The mission dependability model of combat unit was researched under conditon of uncontinuous work and taking account of replacement maintenance and supplyment during mission was running.Firstly,analyzing state trasition process of the spare system by use of Markov process,the mission dependeability was considered as distribution function of spare sytem sojourn time under working state within fixed time.And its numerical value was obtained by means of total probability decomposition method.Secondly,according to the mission reliability relationship between single equipment and spare system,minimal mission unit and equipment,combat unit and minimal mission unit,mission dependeability models of single equipment,minimal mission unit and combat unit were established.Finally,the analysis and calculation results of some actual examples showed that the mission dependeability model is effective and feasible.
