我国冷链物流起步较晚,导致生鲜品在配送、装卸、储存等环节的损失率较高,建立完善的冷链物流配送体系意义重大.根据生鲜品的特点,构建了包含运输成本、货损成本、能耗成本和惩罚成本的线路模型,并采用节约算法,对该模型进行了优化,以期在最大化节约成本和时间窗约束的条件下,确定合适的配送线路,最终通过相应实例,证明了该配送线路优化模型的有效性.

The cold chain logistics in China starts late, As a result, the distribution, loading and unloading, and storage of fresh food has high loss rate, so it is significant to establish perfect cold chain logistics distribution system.According to the characteristics of fresh food, the study build a line model in terms of transportation, cost of damage, energy consumption and penalty cost and optimized this model by means of saving algorithm, so as to determine appropriate distribution lines to maximize cost savings and time window constraints.Finally, this model is effective proved by the corresponding instance.
