基于收益共享契约的低碳供应链协调策略研究

Research on Coordination of Low-carbon Supply Chain Based on Revenue Sharing Contract

摘要:

针对由一个制造商和供应商构成的两级供应链,且生产具有碳排放需求弹性的产品,构建随机需求下的利润模型。研究联合决策条件下,最大利润及最小碳排放时的生产量及碳排放量,分析在分散决策时,制造商如何利用收益共享契约,在不减少双方各自利润的前提下,鼓励供应商加大减排投入额,进而降低供应链碳排放,最终达到双赢的目标。最后,通过数值分析表明,不同条件下联合决策总是优于分散决策,同时,界定可行的利润分配比例范围并分析不同分配比例对制造商和供应商利润所造成的影响。

Abstract:

Based on the profit model of two-echelon supply chain, which consists of one supplier and one producer, and facing the product with carbon emission(CM) elastic, this paper researches the production quantity and carbon emission in the centralized supply chain with considering of maximizing profit and minimizing CM. Then this paper analysis the method that stimulate the supplier to reduce the CM by allocating producer profit to supplier under the revenue sharing contract. We can achieve win-win objective that decrease the CM and maintain profit. In the end, the numerical analysis shows centralized supply chain superior to decentralized supply chain under different situations. At the same time, this paper defines the feasible sharing profit ratio which affects the every member’s profit of supply chain.
