不同碳排放政策下考虑碳减排投入的供应链协调

Supply Chain Coordination of Carbon Reduction Technology Investment under Different Carbon Policy

在考虑碳减排技术投入下,为了实现不同碳排放政策下的供应链协调,通过建立集中式和分散式决策下的供应链模型,根据供应链协调的条件,给出了供应链实现协调的契约形式及契约参数。为了确定不同碳排放政策下的最优订货量和最优碳减排率,通过对博弈模型进行优化,提出了具体的求解方法。数值计算结果表明:随着碳排放政策的变化,供应链的最优订货量、最优碳减排率和供应链的利润也将发生相应的变化,而生产成本、缺货损失、产品残值、销售价格、批发价格等参数变化不仅会影响最优订货量、最优碳减排率和供应链利润,还会影响收益共享比例、碳减排技术投入和碳排放成本的分摊比例。

Considering manufacturer technology to reduce emission, in order to achieve supply chain coor- dination under different carbon policy, supply chain models respectively under the centralized decision- making and decentralized decision-making are established, according to the conditions of the supply chain coordination, and the contract form and contract parameters of supply chain coordination are given. In or- der to determine the optimal order quantity and the optimal rate of carbon emission under different carbon policy, a concrete solving method is put forward through optimization of the game models. A numerical cal- culation results show that the optimal order quantity, the optimal carbon reduction rate and the profit of the supply chain under different carbon policy are different and they change with the changes in carbon policy. The changes of various parameters such as cost of production, back order loss, the salvage value of prod- uct, sales price, wholesale price not only affect the optimal order quantity, the optimal carbon reduction rate and the profit of the supply chain, but also affect income sharing ratio and the proportion of investment in carbon reduction technology and the cost of carbon emission proportion.
