摘要
动车组配送供应链网络优化设计包括供应商招标、配送中心选址、配送路线规划等多方面,是典型的具有NP难性质的MSDLRP问题。采用启发式思想,将该复杂问题模型层层分解,剔除0-1变量,得到一系列简单运输问题子模型。实例证明所提设计思想在实际应用中具有清晰的指导性和科学可行性。
The design and optimization of EMU supply chain network include supplier IFB, distribution center allocation, and distribu- tion route planning, etc., which is thus a typical NP-hard MSDLR problem. The paper follows the guidance of the heuristic algorithm; first it breaks the complex problem into single layers and then, by eliminating the 0-1 variables, it arrives at a series of sub-models of simple trans- portation problems. Finally an empirical study proves that the ideas proposed in the paper can serve as a clear guideline and ensure feasibility in practical application.
