基于利他偏好的鲜活农产品供应链决策研究

Research on decision of supply chain of fresh agricultural product based on altruism preference

本文考虑供应链成员的利他偏好以及鲜活农产品的新鲜度和运输损耗特性,建立了鲜活农产品供应链决策模型.分别研究了供应商具有利他偏好、销售商具有利他偏好以及双方同时具有利他偏好时的供应链决策,得到了采购量和批发价格的最优解析解,进而分析了利他偏好对供应链决策以及供应链效率的影响.研究结果表明,利他偏好行为能够显著影响供应链的最优决策,且当双方均具有利他偏好且利他偏好在一定范围内时,供应链成员的利他偏好能够提高鲜活农产品供应链的效率.较高的供应商利他偏好能够提高供应链的效率,而较高的销售商利他偏好却会降低供应链的效率.另外,研究结果也表明,新鲜度因子和运输有效因子对最优决策和供应链利润也有明显影响.最后以数值分析说明研究结果的正确性.

Considering both altruism preferences of supply chain members and freshness and transportation loss of fresh agriculture products, the paper establishes the decision model of supply chain of fresh agricultural products. We study supply chain decision when the supplier owns altruistic preference, retailer owns altruistic preference as well as both supplier and retailer own altruism preferences, and then obtain optimal order quantity and optimal order price. Futhermore, we analyze the effect of altruism preference on both optimal decision and efficiency of supply chain. The results show that the altruism preference can significantly affect the optimal decision of supply chain. ~Vhen both supplier and retailer own altru- ism preference and their altruistic preferences are within a certain range, their altruistic preferences will improve the efi%iency of supply chain of fresh agricultural products. The higher degree of altruistic pref- erence of supplier will increase the efficiency of supply chain, but the higher degree of altruistic preference of retailer will decrease the efficiency of supply chain. The results also show that the freshness degree and transportation effective factor can affect both the optimal decisions and supply chain profits. Finally, a numerical example is provided to support the findings.
