在全状态集成法的基础上提出了求解设备故障率的新方法:等效状态评分法.以设备等效状态评分为模型,模型参数随着设备所经历的过程变化而变化.通过对经历过检修后的状态评分的折算,表征出检修对设备故障率的影响,求得设备可能的故障率.最后,通过算例运用等效状态评分法求解设备的模型参数和故障率,等态状态评分法和全状态集成法的计算结果相同.与全状态集成法相比,等态状态评分法简化了计算,并且物理意义更加明确.

In this paper,on the basis of the all-state integ-ration (ASI)method,we propose a new method,namely the equivalent condition score(ECS)method,to calculate the failure rate of the equipment. The proposed method is based on the equivalent condition score model,and parameters of the model vary with the process the equipment has experienced. And through the conversion of the condition scores evaluated after maintenance,we can investigate the effect of maintenance on the failure rate, and then calculate the failure rate of the equipment. The results of the ECS method are the same as those of the ASI method. Compared with the ASI method,the ECS method can simplify the calculation process,and also have more specific physical meaning.
