电子信息制造产业闭环供应链生态网络均衡模型

Ecological Network Equilibrium Model of Closed-loop Supply Chain of Electronic Information Manufacturing Industry

以变分不等式理论为基本工具,建立带有生态指示因子且由电子信息制造产业原材料供应商、具有回收运作功能的制造商、零售商及需求市场所构成的电子信息制造产业闭环供应链生态网络均衡模型。通过该系统模型的构建过程,探讨原材料的有效使用及废弃物的低排放治理条件,针对该生态产业多层次的复杂网络结构,描述其各层决策主体的利润最优化均衡条件,明确生态指示因子的重要作用,探讨变分不等式问题解的性质,并构造算例对模型的正确性和合理性进行验证。

Through variational inequality theory, we propose a model of closed - loop supply chain network equilibrium with ecological indicators of the electronic information manufacturing industry, consisting of raw material suppliers of the e- lectronic information manufacturing industry, manufacturers with recovery operation function, retailers and demand mar- kets. The system model is built to construct effective use of raw materials and low emission control condition. We describe the equilibrium profit optimization of decision - making bodies in view of the complex network structure of the ecological in- dustry, and make clear of the importance of ecological indicator. Finally, we investigate the nature of the variational ine- quality problem and construct an example to verify the validity and rationality of the model.
