【摘要】：近年来,随着我国生鲜市场的快速发展,冷链物流迎来了新的发展契机。由于我国冷链物流起步晚,发展慢,尚未形成体系,难以实现跨区域和反季节销售活动,从而出现了产量高、销售量小的局面,也是导致生鲜农产品价格高、品质差的重要原因。首先,对我国生鲜农产品冷链物流进行概述,分析我国冷链物流发展现状,针对生鲜农产品冷链物流的特殊性,分析和定义冷链物流配送过程中的时间、温度和货损成本,建立配送总成本最小化模型;其次,进一步探索冷链物流配送路径优化研究的方案;最后,通过节约成本法加以分析求解,验证模型和算法的可行性。结果表明,基于时温特性处理生鲜农产品冷链物流配送路径问题,节约成本法达到降低配送成本、满足客户需求时间的双重要求。随着时间的推移,生鲜农产品物流成为未来物流业发展的重要方向。
[Abstract]:In recent years, with the rapid development of fresh market in China, cold chain logistics has ushered in a new development opportunity. Due to the late start and slow development of cold chain logistics in China, it has not yet formed a system. It is difficult to achieve cross-regional and off-season sales activities, thus there is a high output, small sales volume, but also leading to high prices of fresh agricultural products, poor quality important reasons. This paper summarizes the cold chain logistics of fresh agricultural products in our country, analyzes the development status of cold chain logistics in our country, and analyzes and defines the time in the distribution process of cold chain logistics for fresh agricultural products according to the particularity of cold chain logistics of fresh agricultural products. Temperature and damage cost, establish distribution total cost minimization model; Secondly, further explore the research scheme of cold chain logistics distribution route optimization; Finally, the feasibility of the model and algorithm is verified by cost-saving method. The results show that the cold-chain logistics distribution path problem of fresh agricultural products is dealt with based on time-temperature characteristics. With the passage of time, the logistics of fresh agricultural products becomes an important direction of logistics industry in the future.
