Abstract:Due to the fault management of the original equipment of the enterprise, it is not possible to analyze the fault in time, it is basically a temporary fire-fighting treatment, the fault site and can not be fundamentally improved. The cause of the fault can not be systematically analyzed, can not be very good classification of the fault, after the failure, the lack of emergency plans for the fault, the fault level is not clear, the effective measures to deal with the failure can not be put in place, the failure treatment efficiency is low and so on. Therefore, with the help of fuzzy evaluation technology, this paper helps equipment managers to make effective judgments on equipment failure, understand the macro-law of failure, grasp the trend of equipment state in a timely and effective manner, take effective measures and methods to control the occurrence of failure. At the same time, the effective management of equipment failure can effectively reduce the frequency of equipment failure, reduce downtime, energy saving and consumption reduction, reduce the use of spare parts materials, while improving the efficiency of fault resolution.
