考虑碳减排技术的闭环供应链生产决策及协调

考虑由一个制造商和一个负责回收的零售商组成的二级闭环供应链，研究不同情形下(无碳减排技术、考虑碳减排技术、考虑碳减排补贴)闭环供应链的最优生产决策及协调问题，并进行比较和数值分析.研究结果表明：二部定价契约和支付转移机制相结合可以实现3种情形下系统的协调；无碳减排技术、考虑碳减排技术、考虑补贴情形下利润和产量依次增加，单位碳排放量依次减小，回收价格保持不变；产量、零售商利润、系统利润以及碳减排量是碳减排投资参数的减函数，单位产品碳排放量是碳减排投资参数的增函数，而制造商利润在一定条件下是碳减排投资参数的减函数，否则是其增函数.

Production decision and coordination of closed-loop supply chain with carbon reduction technology

With a two-echelon closed-loop supply chain consisting of one manufacturer and one retailer responsible for recycling taken into consideration， the closed-loop supply chain production decisions and the coordination under different situations (unconstrained condition， considering the carbon emission reduction technology and considering subsidies for carbon emission reduction) are studied. Then comparison and numerical analysis are made. The results indicate that the combination of the two-part tariff contracts and payment transfer mechanisms are able to achieve system coordination； under the unconstrained condition， the carbon emission reduction technology and subsidies， the optimal profit and quantity gradually increases， while the unit of carbon emissions quantity gradually decrease and the recycling price remains unchanged； the carbon emission reduction investment coefficient is always negatively related to the carbon emission reduction quantity， while the production and system profits as well as carbon emissions per unit product are always positively related to carbon emission reduction investment coefficient； the manufacturer's profit is a decreasing function of carbon emission reduction investment coefficient under certain conditions， or otherwise an increasing function.
