Abstract

In order to solve the problem of high inventory cost existing in the EMU spares SCN, this paper takes the selection of spares center location and EMU model assignment as the optimization content, and takes the total cost of supply chain as the optimization goal. In addition, we propose the network structure of spares supply chain of EMU considering inventory pooling of the same model and establishes a mixed integer programming model. At the same time, based on the nonlinear characteristics of the objective function, the Generalized Benders Decomposition algorithm is used to solve the model, and the numerical experiment and case analysis are done subsequently. The results show that the proposed SPs SCN structure can significantly reduce the total spare part supply chain cost while maintaining a relatively high supply service level to satisfy demand from rolling stock depots and railway bureaus.
