以多层供应链框架为基础,建立了包含多种决策者且考虑库存的区域运输网络均衡模型。首先分析了区域运输的基本流量约束和广义运输费用函数;接着,依次对生产厂商、分销零售商和消费者的决策行为进行分析,得到对应的网络均衡条件;最后通过整合各个决策者的网络均衡条件,得到最终的区域运输网络均衡模型。新模型具有如下特点:①体现了多种决策者既合作又竞争的决策行为;②考虑了区域运输中多货种多方式的特征;③将多层供应链框架融入现实运输网络的流量均衡分析;④利用超级网络理念考虑了可能的货物库存问题。通过算例验证了模型的有效性。
Based on the multi-layer supply chain framework, a regional transport network equilibrium model with multiple decision-makers and inventory is established. Firstly, the basic traffic constraints and the generalized transportation cost function of regional transport are analyzed. Secondly, the decision-making behaviors of manufacturers, distribution retailers and consumers are analyzed to obtain the corresponding network equilibrium conditions. Finally, by integrating the network equilibrium of each decision maker, Conditions, the final regional transport network equilibrium model. The new model has the following characteristics: (1) reflects the decision-making behaviors of a variety of decision-makers both in cooperation and competition; (2) considers the characteristics of multi-goods and multi-modes in regional transport; (3) integrates the multi-layer supply chain framework into the real- ; ④ use of the concept of super network to consider the possible inventory of goods. The effectiveness of the model is verified by an example.
