Preventive maintenance strategy of equipment considering energy efficiency
Aiming at the problems of high energy consumption,low product quality and high maintenance cost of manufacturing production equipment,a preventive maintenance decision model for equipment considering energy ef-ficiency was proposed.Considering the actual situation,the preventive maintenance cost and the operating energy consumption of equipment were closely related to the degradation of equipment,the failure rate of equipment was modeled to obtain the variable preventive maintenance cost and the variable energy consumption firstly,and the quality of the product was constrained by using the quality loss cost,and the recovery of the defective products was taken into account.Then,with the optimization objectives of minimizing maintenance cost and maximizing energy efficiency,a multi-objective decision model of integrated cost and energy efficiency was constructed,and the combi-nation of preventive maintenance thresholds as well as the number of maintenance was obtained using the NSGAⅡand fuzzy theory.Finally,the validity and practicality of the model were verified by comparing it with the single-ob-jective maintenance strategy.
