需求依赖减排水平和价格的供应链决策与协调机制

针对由一个低碳产品制造商与一个零售商组成的供应链, 考虑需求同时受减排水平和销售价格的影响, 分别研究寄售契约、收益共享契约以及收益共享与减排成本共担3 种契约下供应链企业的优化决策, 并进一步探讨当需求的确定部分为和式、随机部分服从均匀分布时的供应链系统的最优决策. 从理论上证明了制造商与零售商之间的合作利于促进减排水平的提升, 也利于供应链系统期望总利润的增加. 最后, 探讨了不同参数对协调供应链绩效的影响.

Decision and coordination models for supply chain with carbon emissions reduction level and price dependent demand

Based on three different contracts (i.e. consignment, revenue sharing, and revenue sharing with reduction-costsharing), decision models are developed in the supply chain, which consists of a low carbon manufacturer and a retailer, and meanwhile the customer demand is affected by emissions reduction level and selling price. Furthermore, assuming that the deterministic component of the demand is linear form and the random component of the demand follows a uniform distribution, the optimal decisions are explored under centralized and decentralized systems respectively. The results show that supply chain cooperation can raise the emissions reduction level and increase the expected total profit. Finally, the effects of different parameters on the coordination of supply chain’s performance are discussed.
