【摘要】：随着电子商务时代的到来，消费者对物流配送的要求也越来越高，配送必须要做到快速、准确与及时，那么如何来提高物流配送的效率呢？构建合理的配送路线，优化配送的整个体系，实现配送成本的最小化将是问题的关键，这个工作难度将非常巨大，同时也关系着整个物流行业是否能快速与健康地发展，这个问题也值得学者们和物流企业管理者深思和探讨。经过多数学者的验证可知，合理利用现代信息技术，结合数学模型、运筹学与等相关学科知识来优化配送管理，提高配送服务的质量与配送管理的水平，是企业提高物流配送效率，，减少成本，实现快速发展的有效途径。目前国内外在配送路线的研究方面也有了很多成果，如运用精确算法、启发式算法等多种类型的算法来构建最优配送路线。本文主要研究工作如下：首先分析了零担物流配送业务流程。对零担物流基本定义、特点及配送流程做了简要论述，同时讨论了配送的定义、特点以及配送路线优化的必要性等。其次，概述了W物流股份有限公司的配送业务情况。详细阐述了W物流的整体配送业务流程与广州区域配送中心的运营现状，通过对广州区域配送中心的组织架构、配送影响因素的分析，指出了目前配送中心所存在诸如信息化程度不高、运力浪费等诸多问题。再次，构建配送路线优化模型并进行系统设计。针对配送业务中的时间窗约束，载重量约束，路况等不确定因素约束以及有限运力约束,建立了配送路线优化模型，并运用改进的C.W节约算法对配送路线安排进行了求解步骤分析，同时运用Dorado展现框架进行了系统设计。最后引入W物流广州区域的实际业务数据，通过对比改进的C.W节约算法和传统的C.W节约算法在实际计算中的结果，验证了改进的C.W节约算法的优越性，同时也表明了此系统在配送路线优化上具有合理性与实用性，能够给配送路线决策提供相关的科学依据。
[Abstract]:With the arrival of the electronic commerce era, consumers have higher and higher requirements for logistics distribution, distribution must be fast, accurate and timely, so how to improve the efficiency of logistics distribution? Constructing a reasonable distribution route, optimizing the whole distribution system and minimizing the distribution cost will be the key to the problem, and this work will be very difficult. At the same time, it is also related to the rapid and healthy development of the entire logistics industry, which is also worthy of scholars and managers of logistics enterprises to ponder and discuss. Rational use of modern information technology, combined with mathematical models, operational research and other related disciplines to optimize distribution management, improve the quality of distribution services and the level of distribution management, is to improve the efficiency of logistics distribution. The effective way to reduce cost and achieve rapid development. At present, there are many achievements in the research of distribution routes at home and abroad, such as the use of accurate algorithms. Heuristic algorithm and other kinds of algorithms are used to construct the optimal distribution route. The main research work of this paper is as follows: firstly, this paper analyzes the business process of distribution of part load logistics. It briefly discusses the basic definition, characteristics and distribution process of part load logistics, and discusses the definition of distribution at the same time. Characteristics and distribution route optimization of the necessity. Secondly. This paper summarizes the distribution business of W Logistics Co., Ltd., expounds the overall distribution business process of W logistics and the operation status of Guangzhou Regional Distribution Center in detail, and through the organizational structure of Guangzhou Regional Distribution Center. Analysis of distribution factors, pointed out the current distribution center such as low degree of information, capacity waste and many other problems. Again. In order to solve the problem of time window constraints, load constraints, road conditions and limited capacity constraints, a distribution route optimization model is established. And the improved C.W saving algorithm is used to analyze the solving steps of distribution route arrangement. At the same time, the Dorado framework is used to design the system. Finally, the actual business data of W logistics area in Guangzhou is introduced. The superiority of the improved C.W saving algorithm is verified by comparing the results of the improved C.W saving algorithm and the traditional C.W saving algorithm in the actual calculation. At the same time, it also shows that the system is reasonable and practical in the distribution route optimization, and can provide relevant scientific basis for the distribution route decision.
