求解供应链分销模型的双层规划方法

Bi-level programming method for distribution network model in supply chain

以一个多仓库、多分销点的供应链二级分销网络为研究对象,分别从供应链上、下游企业的角度出发,以各自的物流成本最小化为目标,利用双层规划方法建立了供应链分销网络优化模型.讨论了该模型的求解方法,并结合分层迭代的思想给出了一个有效的算法,最后借助于计算机技术实现了对模型的仿真计算.

The two-echelon distribution network in supply chain with multi-depository and multi-distribution places is studied. From the viewpoint of upper and lower enterprises in supply chain, a bi-level programming model is put forward to describe the problem about the operational designing of the two-echelon distribution network, which aims to minimize the cost of logistics for each enterprise. The solution of the model is discussed and an effective algorithm based on the idea of layered iteration is given. Finally, the emulational calculation with the model is carried out on computer.
