政府关于碳排放调控机制下的供应链网络Stackelberg-Nash均衡研究

The Supply Chain Network Stackelberg-Nash Equilibrium Model Under the Carbon Emission Control Mechanism

本文在供应链网络均衡模型基础上,引入政府关于碳排放的调控机制,把政府作为整个网络的‘上层’,而供应链网络作为‘下层’,利用均衡理论和二层规划理论建立政府碳排放调控机制下的整个供应链网络Stackelberg-Nash均衡模型。整个网络的‘上层’领导者——政府首先给出关于碳排放惩罚和奖励的限额指标,对于‘下层’的制造商生产、运输中的排放量如果超出限额就惩罚,少于限额就奖励;‘下层’的网络成员作为跟随者,根据‘上层’的惩罚和奖励政策,制定各自的生产量、交易量。数值试验表明,本文研究的模型可以给出政府制定最优碳排放限额的科学依据,进一步政府可以通过碳排放的奖励和惩罚机制,能够有效的调控供应链网络成员碳排放量,以此来达到节能减排、可持续发展的目标。

Based on the supply chain network equilibrium model,the government regulation and control mechanism of carbon emissions are considered,and a Stackelberg-Nash equilibrium model of a supply chain network is deueloped by the bi-level programming and nonlinear complementarity theory,where the upper level refers to the optimization problem of government taxes and the lower level refers to the competitive behaviors in the network.Finally,numerical examples are solved to test the efficiency of the model and the proposed algorithm based on penalty function method.
