针对网购背景下低碳供应链网络优化问题,运用超网络理论构建了供应链超网络模型。在此基础上,根据变分不等式与优化问题之间的关系,建立了基于供应链各成; 员企业的单体超网络优化模型,以及基于供应链所有成员企业的整体超网络优化模型。并对两种模型进行了应用比较分析,结果表明:在供应链各成员企业的利润最; 大化条件下,企业进行低碳运营投入,能实现其社会环保效益,但其经济效益受到影响;在供应链整体利润最大化条件下,企业进行低碳运营投入,在一定程度上能; 同时实现两种效益。A new task for the optimization of supply chain network is put forward; with the continuous enhancement of people's environmental awareness, the; implementation of more stringent environmental regulations, more and; more consumers choose the way of online shopping. How to construct the; model of supply chain super network? How to build the operational; optimization model for each member of the supply chain? How to build the; overall optimization model of supply chain? And what kind of; optimization model is more conducive to achieve the overall goal of the; supply chain? All these are an urgent problem to be solved. With regard; to above issues, the super network theory is used to model the; low-carbon supply chain based on online shopping. Then the independent; super network optimization model is constructed based on the supply; chain's single member, and the integrated super network optimization; model is also constructed based on all the supply chain members; according to the relation between the variation inequality and; optimization problems. And the solving algorithm of the models is; proposed. Further more, the two models are compared by simulation; application. Finally, it is concluded that the supply chain member can; gain environmental protection benefit if they invest on the low carbon; operation, but its economic benefit is decreased on condition that the; supply chain's single member profit is maximized, and the supply chain; can gain both environmental protection benefit and economic benefit if; they invest on the low carbon operation on condition that the supply; chain' s profit is maximized. The application data is mainly collected; through surveys of the online shops and their suppliers, express; companies, consumers and the relevant literatures. This paper provides a; new perspective for supply chain modeling, a new way of thinking for the; optimization of supply chain network.
