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 Weibull proportional hazards model,the test interval is calculated which takes the acceptable failure rate as constraints.Because the utilization of equipments is affected by multiple attributes such as test expense,failure risk and operational availability,stop duration and other factors,a weighted project compromise method is used to establish a multi-attribute test interval decision-making mode to realize the optimal decision-making of state test interval under multi-factor conditions.Finally,the applicability of the model is validated with the analysis of examples.
