考虑销售努力和运输时间的农产品供应链弹性契约

Quantity Flexibility Contract for Agricultural Product Supply Chain Considering Sales Effort and Transportation Time

目的 进一步实现农产品供应链数量弹性契约利润最大化。方法 在市场需求随机的条件下,考虑销售努力和运输时间为影响需求的关键变量,建立起由供应商和零售商组成的农产品供应链数量弹性契约模型。基于该模型引入奖励与惩罚策略,以实现农产品供应链弹性契约的一致性和有效性。结果 结合农产品特征,通过具体的模型优化方法和算例分析得出最优值以及各变量与最优销售努力水平、最优运输时间、最优订货量和整体农产品供应链利润之间的相关关系。结论 农产品供应链弹性契约能实现协调下的利润最大化,对农业经营主体企业开展农产品供应链弹性研究具有重要的理论和实践价值。

The work aims to further maximize the profit of the quantity flexibility contract for agricultural product supply chain.Under the condition of random market demand,a quantity flexibility contract model for agricultural product supply chain composed of suppliers and retailers was established by considering the sales effort and transportation time as the key variables affecting the demand.Based on this model,reward and punishment strategy was introduced to realize the consistency and effectiveness of agricultural product supply chain flexibility contract.Combined with the characteristics of agricultural products,through the specific model optimization method and example analysis,the optimal value and the correlation between each variable and the optimal sales effort level,the optimal transportation time,the optimal order volume and the overall agricultural product supply chain profit were obtained.The flexibility contract of agricultural product supply chain can realize the profit maximization under the coordination,which has an important theoretical and practical value for the agricultural business subject enterprises to carry out the flexible research on agricultural product supply chain.
