碳排放权交易下供应链三方企业订货和定价决策

Order and Pricing Decisions of Three-Echelon Supply Chain with Cap-and-Trade Mechanism

考虑在碳排放权交易和确定需求函数情况下,对碳排放权供应商、制造商和零售商组成的供应链三方企业订货和定价决策进行研究.本文分别构建了三方企业独立决策模型、部分集中化决策模型和完全集中化决策模型,得到3种情形下供应链各成员的最优订货、定价和最大利润.最后,运用算例分析得到:完全集中化决策下供应链的利润大于部分集中决策下的供应链利润,更大于分散决策下的供应链利润;供应链总利润随着单位碳排放权成本、单位产品碳排放量的减小而增大,随着市场规模的增大而增大.

This paper considers a price-incentive demand function with cap-and-trade mechanism,discusses the order and pricing decisions in the three-echelon supply chain system which includes carbon-emissions right suppliers,manufacturer and retailer.Based on game theory,three models are developed,and we solve the optimal decisions and profits of supply chain.At last,a numerical example is given to show that the supply chain's profit in the fully centralized decision model is highest than that in the partial centralized decision model and independent decision model.As the cost of carbon emission increases,the emission of unit product decreases.Meanwhile,the market size increases,the profits of the supply chain also increase.
