[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.
