【摘要】：在时变需求下,供应链网络静态均衡模型不能描述上下游成员的订单、库存以及采购价格随时间的变化的传播过程.通过在静态均衡模型中引入了时间变量,本文构建了供应链网络动态均衡模型,以描述供应链网络各成员订单、库存和价格的时变特征.基于历史的订单、采购\销售价格等信息,给出了供应链成员考虑订单提前期和库存成本的订单生成策略的数学描述.建立了供应链网络动态竞争均衡变分不等式模型,利用变分不等式方法给出了等价的动态均衡条件,并设计了求解模型的有效算法.算例研究表明:文中建立的动态模型不仅能嵌入不同的订单生成策略,还能分析包括牛鞭效应在内的多种供应链网络问题.本文所提出的模型为探究供应链网络时空演化行为提供了有力的工具.
[Abstract]:Under the time-varying demand, the static equilibrium model of supply chain network can not describe the propagation process of the order, inventory and purchase price of upstream and downstream members with time. In this paper, a dynamic equilibrium model of supply chain network is constructed to describe the time-varying characteristics of order, inventory and price of each member of supply chain network. The mathematical description of order generation strategy for supply chain members considering order lead time and inventory cost is given. The variational inequality model of dynamic competition equilibrium of supply chain network is established, and the equivalent dynamic equilibrium condition is given by using variational inequality method. An effective algorithm is designed to solve the model. The example shows that the dynamic model can not only embed different order generation strategies. The model presented in this paper provides a powerful tool for exploring the spatiotemporal evolution behavior of supply chain networks.
