摘　　要：针对生鲜农产品"最后一公里"配送时效性强的特点,引入生鲜损耗度系数来表征农产品价格随时间推移而下降的特性,提出了带时间窗的"最后一公里"配送模型。运用本德斯分解法对随机算例进行求解,以验证模型的准确性。In this paper, in view of the strong timeliness requirement of the last mile distribution of the fresh farm produce, we introduced in the freshness loss coefficient to reflect the characteristics of the farm produce whose price drops with time, and proposed the last mile distribution model with time window. At the end, we used Benders decomposition to verify the accuracy of the model.
