动态环境下基于移动通信的闭环供应链超网络模型

A Closed-loop Supply Chain Supernetwork Equilibrium Model with Time-dependent Parameters Based on Mobile Communication

在动态环境下建立了一个基于移动通信的闭环供应链超网络模型.在该模型中,各层决策者可以通过两种手段进行交易,一种是传统意义上的交易方式,另一种则是借助移动通信手段进行交易.在所描述的网络模型中,价格敏感度和时间是影响需求市场需求的两个重要因素.同时,还借助一个简单的周期函数来描述需求市场对商品的季节性需求.以各层决策者寻求利益和风险的均衡点作为优化目标,并通过变分不等式理论对该模型进行求解.利用具体的算例验证了该模型的正确性和合理性.

This paper develops a 5-tiered closed-loop supply chain network model based on mobile com- munication in dynamic environment. In the model, the decision-makers can transact via both the tradi- tional way and the other way based on mobile communication. In the network, there are two factors affecting demand market＇s demand, they are the price sensitivity wand time t. Specifically, a simple cyclic function is used to describe the demand market＇s seasonal demand. The decision-makers seek the equilibrium of profit and minimization as their optimization objectives by using the theory of varia- tional inequality. Then the model is verified reasonably by numerical example.
