时间约束下鲜活农产品三级供应链协调

针对一个生产商-分销商-零售商构成的鲜活农产品三级供应链,构造了运输过程中的依赖于运输时间的新鲜度和损耗比例模型,分别求出供应链各级成员的最优期望利润以及收益共享契约协调下的利润分配。研究结果表明:收益共享契约能有效地协调三级鲜活农产品供应链,契约参数Φ在一定范围内可实现三方共赢,且最优期望利润随着需求价格弹性k和运输时间t的增加而减少。最后以数值算例说明研究结果的正确性。

Three-level Supply Chain Coordination of Fresh Agricultural Products with Time Constraints

For a fresh agricultural supply chain consisting of one manufacture and one distributor and one retailer,this paper respectively figures out the optimal expected profit under three levels of supply chain and also figures out the profit distribution of each member in the supply chain under the coordination of revenue-sharing contract.The results show that the revenue-sharing contract is able to coordinate the three-level fresh agricultural supply chain effectively.This model allows the system efficiency to b...
