基于“互联网+”的双目标多期供应链网络平衡研究

Study on Multiperiod Supply Chain Network Equilibrium with Two-objective of Internet Plus

"互联网+"使电子商务发展迅猛,供应链上的成员通过线上和线下双渠道进行交易。在国家绿色环保的号召下,供应链上的企业在交易过程中应考虑对环境的影响。综合考虑"互联网+"时代的特点和绿色环保两大因素,构建了基于"互联网+"的动态供应链网络平衡模型,探讨由生产市场、零售市场和消费市场构成的动态供应链网络的平衡问题,其中,生产商和零售商均以利润最大化和污染最小化为目标。利用变分不等式构建各层市场的平衡模型,推导出各决策者的平衡条件,得到最终的基于"互联网+"的双目标多期供应链网络平衡模型。通过算例分析得到的平衡产量、库存量、交易量和平衡价格,用于指导供应链上的企业决定其销售价格和生产规模等。

＂Internet plus＂promote the rapid development of electronic commerce, the members of supply chain traded by the dual channel of outline and online. To response to the national call of green environmental protection, businesses in supply chain also considered the impact on environment. Comprehensively considering the characteristic of＂ internet plus＂ and green environmental protection, the multiperiod supply chain network equilibrium model is constructed under the online and the traditional outline trading channel. A three-tiered dynamic supply chain network structure of＂internet plus＂, which consisted of manufacture market,retailer market and demand market were developed. Assuming that the manufacturers and retailers are the pursuit of profit maximization and pollution minimization. In virtue of variational inequality theory, the equilibrium model of different tiers was constructed, and the equilibrium condition of each tiered decision makers was given. In the end, the multiperiod supply chain network equilibrium model with two-objective of＂internet plus＂was obtained. With the numerical example, equilibrium output, product flow, inventory, and equilibrium price are essential to guide price and capacity of enterprises in supply chain.
