随机需求下绿色农产品三级供应链协调

考虑市场随机需求、产品绿色度、绿色研发成本等因素,研究绿色农产品三级供应链协调问题。首先,构建了不同决策模式下供应链成员的利润模型,发现合作可提高供应链整体收益,随后构建"收益共享?成本共担"混合契约对绿色农产品供应链进行协调。研究结论表明:混合契约能够降低绿色农产品售价,提高绿色度,增加绿色农产品市场需求;合理比例的收益共享和成本共担可使各个绿色供应链成员达到共赢。最后通过算例分析验证了契约模型的正确性。

Three-Level Supply Chain Coordination of Green Agricultural Products under Stochastic Demand

The factors of market random demand, product greenness, green R&D cost, etc. are considered, and the coordination of three-level supply chain of green agricultural products studied. Firstly, the profit model of supply chain members under different decision-making models is constructed. It is found that cooperation can improve the overall income of the supply chain, and then a "revenue sharing and cost sharing" hybrid contract is constructed to coordinate the green agricultural product supply chain. The research results show that the hybrid contract can reduce the price of green agricultural products, increase the greenness, and increase the market demand for green agricultural products; and that a reasonable proportion of revenue sharing and cost sharing can achieve a win-win situation for each green supply chain member. Finally, the correctness of the contract model is verified by an example.
