Abstract: An optimal configuration model of spare parts under the condition of improved spare part fill rate is established in order to overcome the disadvantage of that traditional system spare parts fill rate is prone to minimum. An improved layered margin optimization algorithm is given to improve the optimization efficiency of algorithm by using the layered optimization idea. The detailed optimization flow of the algorithm is given, and the optimization efficiency of the algorithm is analyzed in theory. The correctness and rationality of the model are proved by analyzing the calculated result of an example.
