考虑交通拥堵成本的零售商供货量决策模型

Supplying policy model of retailer considering traffic congestion cost

引入交通拥堵成本因子,考虑从零售商配送中心到市场间的路段存在交通拥堵情况下,分别建立了供应链系统中供应商定价模型和零售商供货量模型;运用动态博弈分析方法,得出了零售商和供应商满足利润最大化条件下解的均衡方程;最后,研究了一个简化的供应链网络,对上述模型进行了验证与分析。结果表明,随着交通拥堵成本因子的不断增大,零售商会逐渐减少对市场的商品供货量,通过提高市场价格和减少运输费用来弥补拥堵成本的增加。

Introduction to traffic congestion cost factor,assuming that there were some traffic congestion on the road between retailer’s distribution centers and markets,this paper built the supplier’s price choice model and retailer’s supplying model.By using the method of dynamic game,this paper got the equilibrium of the supplier and the retailer based the maximum of profit respectively.Researched on the simplified supply chain network,it verfied the model.The results show that,with the traffic congestion cost factor increasing,the retailer will decrease the supply quantity to markets,by rising the market price and reducing the transportation cost to make up for the increased cost of traffic congestion
