摘要
针对供应链与供应链竞争问题,建立了基于二层规划的供应链网络间的竞争模型,其中上层为政府部门的税收最大化问题,下层为多个供应链网络间的竞争问题.通过定义产品市场链说明了供应链网络之间是如何竞争的,在模型中引入政府宏观调控手段,以产品价格税的形式来说明政府部门对市场的调节职能和作用.研究表明供应链与供应链的竞争可以看作是由核心企业所决定的供应链网络之间的竞争,同时,政府部门的宏观调宏政策可以有效地影响供应链网络之间的竞争行为.最后,给出了求解模型的罚函数法,并通过一个算例对模型进行了检验.
According to the competition problem among supply chains, this paper established a competitive model of supply chain network versus supply chain network based on bi-level programming, where the upper level refers to the optimization problem of government taxes, and the lower level refers to the competitive behaviors among supply chain networks. It explained how supply chains compete against each other by the definition of product-market chain. Moreover, the government macro-control is introduced into the competition problem, and the function of govemment in regulating the market is indicated by way of product price tax. These discussions show that the competition among supply chains can be seen as the competition among supply chain networks that is determined by the core business, and government macro-control policies can effectively affect the competitive behaviors among supply chain networks. Finally, algorithms based on penalty function method are presented, and a numerical example is given to test the model.
