Evaluation Model For Equipment Criticality And Economic Benefits Based On RCM

Maintenance optimization in modern industry, In particular has beenplaying an important role in the repair operation in nuclear power plant, Itis used to improve the reliability of the equipment，To reduce the operatingcost of repair.So, Maintenance optimization has been one of the mostactive research topics in the field repair management for many years.Inmany of the repair optimization method, RCM （Reliability-centeredMaintenance) is Method of Maintenance optimization abroad widely used.This dissertation introduces theory base on RCM，Emphasis was puton the equipment importance and benefit decision problems.Establish equipment criticality evaluationmodel. The repair decisionis based on the experience of managers and technicians In the domestic,Due to personnel changes, the data is not complete, leading to repair thevery randomness, not Repair of excessive, that Repair deficiency. So, It isnecessary to use the RCM theory, To repair equipment according toclassify objects, According to the factors of reliability,maintainability andeconomy of equipment, Determination of equipment importance todetermine the repair method, Implementation of equipment repair cyclecost economy, the highest utilization rate.In this paper, using RCMtheory with AHP（The analytic hierarchy process）establish model ofequipment importance, AHP Provides the reliable basis for the equipmentimportance decision, Very practical for evaluation of complex structure,evaluation index are qualitative. The method is simple and feasible, andthe examples show that the method is feasible.Establish the model of Economic benefit evaluation model RCM.After the analysis of RCM, The most obvious change is cancelled someoriginally not necessary preventive repair work and added somenecessary preventive repair work.To improve the reliability of equipment,reducingthe operation, repair cost. But how to quantitative analysis of RCM madethese benefits, Is always a difficulty in RCM application. The first toclassify RCM economic benefit, Then has carried on the detailed analysisand research on various type svaluation methods. Establish Evaluationmodel of economic benefit. Using this model, Can effectively evaluate theeconomic benefits after analysis of RCM. And the example proved thefeasibility of this method.
