摘要
装备任务成功性是指装备在给定的维修保障方案下成功完成规定任务的能力,其概率度量为任务成功概率,是重要的装备保障性评估指标。可修系统是装备系统重要的组成部分,当系统执行多个子任务构成的复杂任务时,其任务成功概率不仅与系统自身的任务可靠度、固有能力有关,还与每个子任务的准备时间和执行时间、任务成功要求、维修保障能力和数量等因素有关。在充分分析多任务执行过程的特点与可修系统任务成功性影响因素的基础上,给出了一种给定维修保障方案情况下可修系统混合多任务成功概率评估模型。最后,通过一个算例来说明该模型的有效性与实用性。
Mission successfulness means the capacity for material systems fulfilling given missions provided by maintenance support schemes. Its measurement is the mission success probability which is the important index of supportability assessment. The multi-mission success probability of repairable systems is not only dependent on its operational reliability and inherent capacity, but also the span of every sub-mission cycle and intermission, success requirements, quantity and a capacity of maintenance support resources and so on. Based on analyzing the characteristics of the multi-mission process and all the above effect factors, a model is studied on how to evaluate the mixed multi-mission success probability of repairable systems under a given maintenance support scheme. Finally, an example is given to demonstrate the validity and application of this model.
