上海领鲜冷链广州地区物流配送路线优化研究
25页1、2017年5月20日上海领鲜冷链物流配送路线优化研究摘 要历史潮流的推进,社会也在发展,冷链物流逐渐慢慢兴起。但是冷链产品十分特殊,具有相当高的保存要求,所以对于冷链物流的配送线路规划也有十分高的要求。为了保证冷链产品的品质,需要将各种因素都一一考虑,最后综合起来得出一个较完美的解决方案。广州是一个国际大都市,人口众多,经济发达,对于冷链产品需求大。目前,上海领鲜物流在广州只有一家配送中心,但是想要很好的发展冷链物流,一家配送中心是远远不够的,完全不能满足冷链业务的实际情况。所以,本文将广州现有的配送中心作为一级配送中心,然后在11个区分别选址作为二级配送中心,然后对两者之间进行路线上的研究。最后,通过建立VRP模型,运用蚁群算法和MATLAB求解,得到最优路径和最小成本。建立完善的冷链物流运作体系,对于冷鲜而言将大大增加自身的盈利能力。运用实例求解的结果表明,本文所建模型对冷链物流车辆路径优化及控制成本是可行且有效的,保障了冷链食品在运输过程的新鲜度,降低了物流的运输成本和损耗成本,可为相关企业在决策时提供可参考的理论依据1。【关键词】:冷链物流;蚁群算法;MATLABStudy o
2、n Optimization of Logistics Distribution Routes in ShanghaiAbstractThe trend of the advancement of history, society is also developing, cold chain logistics gradually slowly rising. But the cold chain products are very special, with a very high preservation requirements, so for the cold chain logistics distribution line planning also has a very high demand. In order to ensure the quality of cold chain products, need to consider all kinds of factors one by one, and finally together to come up wit
3、h a more perfect solution.Guangzhou is an international metropolis, a large population, economic development, demand for cold chain products. At present, the Shanghai fresh logistics in Guangzhou, only one distribution center, but want a good development of cold chain logistics, a distribution center is not enough, can not meet the actual situation of cold chain business. Therefore, this paper will be the existing distribution center in Guangzhou as a distribution center, and then in 11 district
4、s were selected as a secondary distribution center, and then between the two on the line of research. Finally, by establishing the VRP model, the ant colony algorithm and MATLAB are used to get the optimal path and the minimum cost.Establish a perfect cold chain logistics operation system, for the cold will greatly increase their profitability. The results of the example are used to show that the model proposed in this paper is feasible and effective for the optimization and control of the cold
