以针对冲击失效劣化系统,提出一种新的δ一冲击失效模型,并基于该模型研究了N型更换策略下的不完全维修决策方法.首先通过扩充失效状态,在δ-冲击模型的基础上建立新的δ-冲击失效模型;其次以最小平均费用率为目标、可用度为约束,建立了N型更换策略下系统的不完全维修决策模型;最后用一个算例验证了该方法的合理性,并分析了参数对策略N的灵敏度.
In order to deal with the impact failure failure system, a new δ-impact failure model is proposed, and based on the model, the incomplete maintenance decision-making method under the N-type replacement strategy is studied.Firstly, by expanding the failure state, based on the δ-impact model A new δ-impact failure model is established. Secondly, with the minimum average cost rate as the goal and the availability as a constraint, an incomplete repair decision model of the system under N-type replacement strategy is established. Finally, an example is used to verify the rationality of the method , And analyzed the sensitivity of parameters to strategy N.
