建立了一个由原材料供应商、生产商、零售商、需求市场和回收中心组成的闭环供应链超网络模型.利用均衡理论以及变分不等式的方法分析网络中各层决策者的独立行为及其相互作用进而得到了该系统达到均衡状态的条件.最后,设计了一个数值算例就旧产品的回收率和利用率及旧材料的利用率等参量对超网络系统的运作性能的影响进行了分析同时也验证了该超网络模型的有效性.
A closed loop supply chain super-network model consisting of raw material suppliers, manufacturers, retailers, demand markets and recycling centers is established.Using the equilibrium theory and the method of variational inequality to analyze the independent behaviors of decision makers at all levels in the network and their mutual Then the condition of the system reaching equilibrium condition is obtained.Finally, a numerical example is designed to analyze the influence of the recovery and utilization of old products and the utilization of old materials on the operation performance of super-network system Also verified the validity of the super network model.
