A超市物流配送路径优化研究

摘要随着社会经济进步，人们对日常必需品的需求和质量要求不断提高，超市因商品种类丰富、规模大、购物便利等优势成为满足这些需求的首选场所。然而，在超市物流配送发展过程中仍存在各种问题，如路径规划不合理、配送中心选址不当等，这些问题都会对物流配送产生影响。本研究针对A超市进行深入分析，由于该超市商品种类繁多，需要在多个点位装货导致物流路径冗长且时间成本较高。此外，车辆路线规划也存在不合理情况，增加行驶距离和时间浪费，并可能导致货物损失尤其是生鲜产品需要保持新鲜度以满足客户需求。因此迫切需要解决A超市目前存在的问题。本文首先介绍了研究的背景、目标和意义，并阐述了国内外学者关于超市物流配送和路径优化方面的研究成果。同时阐述了与物流配送、超市配送以及冷链配送相关的概念知识。基于此基础上采用文献研究和数学建模相结合方法进行深入分析并找出A超市当前存在问题之处。本文将以A超市冷链物流配送为对象，在指导下使用遗传算法剖析该超市在冷链物流配送中产生各项成本，以实现综合成本最小化为目标函数建立数学模型。通过引用实际案例对所建立数学模型进行分析并运用遗传算法解答得出最佳路径，最后验证结果。该研究结果可供A超市冷链物流配送行业优化物流配送路线、降低物流配送成本等方面的参考。关键词：冷链配送：遗传算法：物流配送：路径优化AbstractWith the progress of social economy,people's demand for daily necessities and qualityrequirements are constantly improving.Supermarkets have become the preferred place to meetthese needs due to their rich variety of goods,large scale,and convenient shopping.However,there are still various problems in the development of supermarket logistics distribution,such asunreasonable path planning and improper location of distribution center.These problems willhave an impact on logistics distribution.This study conducts an in-depth analysis of SupermarketA.Due to the variety of commodities in the supermarket,it is necessary to load at multiple points,resulting in long logistics paths and high time costs.In addition,there are also unreasonablesituations in vehicle route planning,increasing driving distance and time waste,and may lead toloss of goods,especially fresh products,which need to be kept fresh to meet customer needs.Therefore,it is urgent to solve the existing problems of A supermarket.This paper first introduces the background,objectives and significance of the research,andexpounds the research results of domestic and foreign scholars on supermarket logisticsdistribution and path optimization.At the same time,it expounds the conceptual knowledgerelated to logistics distribution,supermarket distribution and cold chain distribution.Based onthis,the combination of literature research and mathematical modeling is used to conductin-depth analysis and find out the current problems of A supermarket.This paper will take thecold chain logistics distribution of supermarket A as the object,use the genetic algorithm toanalyze the various costs generated by the supermarket in the cold chain logistics distributionunder the guidance,and establish a mathematical model with the objective function ofminimizing the comprehensive cost.By referring to the actual case,the established mathematicalmodel is analyzed and the optimal path is obtained by using the genetic algorithm.Finally,theresults are verified.The research results can be used as a reference for A supermarket cold chainlogistics distribution industry to optimize logistics distribution routes and reduce logisticsdistribution costs.Key words:cold chain distribution;genetic algorithm;logistics distribution;path optimization目录摘要.Abstract..第一章绪论…1.1研究背景及意义1.1.1研究背景1.1.2研究意义…1.2国内外研究现状1.2.1国外研究现状…21.2.2国内研究现状.31.3本文的研究内容和方法41.3.1研究内容…41.3.2研究方法.51.3.3技术路线图.5第二章
