单一商品多层次供应链网络均衡模型研究

Single Commodity Multi-level Supply Chain Network Equilibrium Model

供应链管理是企业的有效性管理,表现了企业在战略和战术上对企业整个作业流程的优化。为分析供应链中各个主体的最优决策及均衡条件,建立一个由原材料供应商、制造商、零售商与消费者市场构成的具有单一商品流动的4层供应链均衡模型。对供应链的网络结构进行分析,利用有限维变分不等式建立起各个部分的均衡模型并给出经济解释。最终得到各个主体的均衡条件,并给出4则算例证明模型的合理性。

Supply chain management reflects the effectiveness of management, indicating how the enterprises optimize their entire operation both in strategies and tactics. In order to analyze every member＇ s optimal decision and equilibri- um conditions in the supply chain, we establish a multi-level supply chain contains raw material suppliers, manufac- turers, retailers and consumer markets with single-commodity. After analyzing the network structure of the supply chain, we established every member＇s equilibrium model in the supply chain by using the finite-dimensional variation- al inequalities; the economic interpretations are given consequently. Eventually we get the equilibrium condition for entire supply chain; then four numerical examples are given to prove the rationality of this model.
