基于价值损耗的生鲜农产品供应链协调

Coordinating Fresh Agricultural Supply Chain under the Valuable Loss

生鲜农产品属于变质产品,但是变质库存管理是针对产品本身的变质属性发展起来的,不能解决生鲜农产品的非变质性价值损耗问题。由此,本文针对现有文献对损耗尚停留在定性描述阶段,构造了一个指数形式的新鲜度衰减函数,尝试用新鲜度表征价值损耗,在此基础上定量研究两级生鲜农产品供应链协调问题。研究发现,考虑价值损耗的情况下,集中式决策不能使生鲜农产品供应链达成协调。

Fresh agricultural product is deteriorating item, but the theories for deteriorating inventory management are incapable of solving the non--deteriorating valuable loss problem. Based on the truth that the literatures in existence describe the loss just with words, this paper creates an exponential function with downward slope, tries to denote valuable loss with greenness, and studies the coordination in two--level fresh agricultural supply chain. The conclusion implies that the centralized decision can＇t make the agricultural product supply chain reach coordination under the valuable loss.
