【 摘 要 】

Modular design is an important means of railway logistics service scheme design. First, the railway logistics process is divided into 19 modules, and each module contains a number of module instances. Secondly, the objective function is the minimum service time, the lowest service cost and the highest quality of service. The constraint conditions are module selection constraints, goods type constraints, maximum cost and maximum time. Then we establish optimization model of railway logistics service scheme configuration. Finally, the NSGA-II method is used to solve the model, and the optimal set of Pareto solutions is obtained. The Hybrid Fuzzy TOPSIS method is used to evaluate the scheme, and the optimal scheme is selected. The results show that the method is effective and reasonable. The method provides a basis for solving the problem of railway logistics agent business service scheme allocation.
