在对威布尔比例故障率模型进行研究的基础上,以可接受的故障风险为约束,计算了装备的检测间隔期。由于装备使用受到故障风险、检测费用、可用度及停机时间等多属性影响,运用基于加权投影折中法建立了模糊多属性状态检测周期决策模型,实现了多因素条件下状态检测间隔期的综合优化决策。最后,通过实例分析验证了该模型的适用性。 Based on the research of the Weibull proportional failure rate model, the detection interval of equipment was calculated based on the acceptable failure risk. Due to the risk of equipment failure, detection cost, availability and downtime, the fuzzy multi-attribute state detection cycle decision-making model was established based on the weighted projection compromise method to realize the integration of state detection interval under multi-factor conditions Optimize the decision. Finally, the applicability of this model is verified by an example analysis.
