【摘要】：随着经济全球化,物流业已经成为推动经济发展的一股重要力量。近几年,物流业务增长迅速,顾客对配送效率和服务质量的要求也不断提高,传统单一的运输方式无法满足市场多方面的需求。作为物流运输高级运输方式,多式联运充分考虑各种运输方式的特点,将它们进行合理地组合,在最大程度上降低运输成本和提高了运输效率,从而促进交通运输的良性发展。本文针对目前我国的基于多方式联运的物流配送现状,分析了基于多方式联运物流配送的需求,结合多式联运物流运输基本特征和组织形式,综合考虑多式联运物流配送过程中的运输成本、中转成本和惩罚成本等成本因素以及货物在途的运输时间和货物在运输节点上的中转时间等时间因素的基础上,建立了以物流配送总成本和运输总时间为目标的多方式联运物流配送网络优化模型,并设计了模型求解的遗传算法,运用模拟案例对所建立的优化模型的实用性进行了验证。本研究旨在对多式联运物流配送网络建立优化模型,得到最合理的物流配送方案,通过提高物流配送效率,降低运输总成本,减少在物流配送过程中的资源浪费,从而对多式联运企业增加物流配送的综合效益,提高服务水平,增强市场竞争力具有重要意义。
[Abstract]:With the economic globalization, the logistics industry has become an important force to promote economic development. In recent years, with the rapid growth of logistics business, customers' requirements for distribution efficiency and service quality are also increasing, and the traditional single mode of transportation can not meet the needs of many aspects of the market. As the advanced transportation mode of logistics, multimodal transport takes full account of the characteristics of various modes of transport, and combines them reasonably to reduce the transportation cost and improve the transport efficiency to the greatest extent, thus promoting the benign development of transportation. According to the present situation of logistics distribution based on multimodal transport in our country, this paper analyzes the demand of logistics distribution based on multimodal transport, combined with the basic characteristics and organizational form of multimodal transport. On the basis of considering the transportation cost, transit cost and penalty cost in the process of multimodal logistics distribution, as well as the time factors such as the transport time of goods on the road and the transit time of goods on the transport node, etc., The optimization model of multi-mode intermodal logistics distribution network with the goal of total cost and time of logistics distribution is established, and the genetic algorithm for solving the model is designed, and the practicability of the model is verified by a simulation case. The purpose of this study is to establish an optimal model of multimodal logistics distribution network, and to obtain the most reasonable logistics distribution scheme. By improving the efficiency of logistics distribution, reducing the total cost of transportation and reducing the waste of resources in the process of logistics distribution. Therefore, it is of great significance for multimodal transport enterprises to increase the comprehensive benefit of logistics distribution, improve the service level and enhance the market competitiveness.
