摘要 k/N热备份冗余系统已被广泛应用在现代高科技装备中,而对于某些k/N系统的k并不是一成不变的,而是根据实际任务而变化的,并且某些系统还存在一定数量的冷备份冗余部件。给出一种存在冷备份冗余部件且k随阶段变化而变化的k/N系统的多阶段任务可靠度模型,通过该模型可以为确定系统在完成特定任务情况下的热、冷备份部件数量提供决策依据,为该类系统的设计提供决策支持。 There are many k-out-of-n systems with both hot and cold standby redundancy used in today's technological (systems.) For some special systems, k is different in different phases. This paper presents a phased mission reliability (mathematical) model for k-out-of-n system with different k in different mission phases. Using this model, we can make a (decision) on the quantity of cold and hot standby parts when the system will implete different missions.
