Abstract: With the ever-progressing equipment standardization and modularization level, the proportion of common spare type and number is increasing. In order to further improve spares support capability, a common spare utilization rate and fill rate model is established. On this basis, a common spare configuration optimization with the constraint of fill rate index is proposed. Case studies show that with the increase of the number of spares, the fill rate of spares will also increase, while the utilization rate of spares will decrease. It is difficult to achieve high results for both fill rate and utilization rate of spares, and to some degree, there is mutual restriction between the two indexes. It is necessary to weigh between spares fill rate and utilization rate according to actual needs so as to identify the primary optimization indexes, and to improve the efficiency of spares. The research results provide support for developing equipment spares requirement demonstration and spare support program.
