摘要
在考虑新品与再创造品差异以及消费者偏好的基础上,建立了碳税约束下制造商负责回收的闭环供应链分散决策模型和联合决策模型。运用二层规划方法对模型进行最优化求解和数值仿真,分析碳税政策和消费者偏好对模型结果的影响,并对分散决策模型和联合决策模型进行比较。结果表明:碳税政策有利于企业减少碳排放,但以降低供应链的利润为代价,随着碳税率的升高,回收率先减后增,再制造品生产规模不断扩大,新品产量减少;联合决策模型在各方面都优于分散决策模型;消费者对再制造品偏好的提高不仅能提高环境效益更具有经济效益,对供应链的影响呈指数化趋势。
On the basis of consideration of product differentiation and consumer preferences,a decentralized pricing model and a joint pricing model are developed under the constraint of a carbon tax policy. This paper uses bilevel programming method to solve the model,and then uses numerical simulation to analyze the impact of carbon tax policy and consumer preferences for the model results. The results show that carbon tax policy is conductive to reduce carbon emissions,while reducing the profit of the supply chain. With the increasing of the carbon tax,the recovery decreases firstly and then increases,the remanufacturing scale expands,the production of new products declines. Joint pricing model is superior to decentralized pricing model in all respects. Enhancing consumer preference for recycled products is proved to be an environmental efficient and economic efficient way to improve the supply chain,and the influence increases exponentially.
