基于卖方管理库存的配送决策优化模型与算法

Optimum Decision-Making Model and Arithmetic Analyzing of Delivery System Based on VMI

为实现供应链一体化和卖方管理库存,建立了同时考虑供给方的配送费用和客户的库存费用的整体优化模型.为降低求解该模型的难度,初步确定送货车辆与客户的对应关系后,将该模型分为库存分配模型和带时间窗的旅行商问题的模型.采用较为成熟的算法即可分别求解这2个模型,然后再将2者合成为原问题的模型.

To implement the integrated supply chain and VMI (Vendor-managed inventory), an optimization model was proposed by taking both the delivery expenses and the inventory expenses of customers into account. Under the condition that vehicles for delivery have been dispatched for specific customers as the preliminary plan, the model can be divided into two submodels of the inventory allocation and traveling salesman problems to reduce the difficulty of solving the model. The submodels can be solved with some available algorithms and integrated into the original model.
