The development of efficient and economical centrifugal compressor key performance spare parts ordering program is very important to improve the maintenance management efficiency of the equipment and reduce costs, this paper proposes a centrifugal compressor based on the reliability of gas supply key performance spare parts maintenance and ordering joint optimization. First of all, based on the average failure rate of compressor unit and the average time between failures to establish unit reliability mathematical model; secondly, based on the unit reliability mathematical model, the establishment of the compressor key components unit preventive maintenance cost model; finally, based on the ordering of spare parts at various moments of the cost function, the working time of the components to establish the compressor key performance parts ordering optimization model, the use of genetic algorithms to get the optimal ordering of the key performance of the spare parts time and optimal replacement of the components time.
