用动态规划模型优化新产品的供应链配置

Optimization of Supply Chain Configuration for New Products by Using Dynamic Programming Model

本文配置一个设计已经决定的新产品的供应链,确定供应链的每个层级选择哪些供应商、零件、流程和运输模式。每个层级之间可能会有多个选项来提供原料、生产或装配产品,以及运输产品给客户。其中,每个选项因其提前期和直接成本的增加而不同。本文考虑到这些不同的选择,提出含有2个状态变量的动态规划模型,配置出使得供应链总成本最小的选项。为企业提供供应链配置相关的决策支持,对实际问题的解决具有很好的指导意义。

This paper proposed a design of the supply chain of the new products, and determined each level of supply chain should choose which suppliers, parts, processes and transport models. Each level may have multiple options to provide raw materials, production or assembly products, as well as the transportation of the product to the customer.Each of these options is different due to the increase in lead time and direct cost. Considering the different options,this paper proposed a dynamic programming model with two state variables, made the minimum allocation of the total cost of supply chain option. It provides decision support for supply chain configuration, and has a good guiding significance for solving practical problems.
