Study on Optimization of Integrated Transportation Organization Mode Based on Various Types of Goods

Abstract

According to the coupling relationship of goods’ transport attributes and transport service’s attributes, the transport goods are divided into four categories. Based on the classification of transport goods, the generalized transport cost functions of time-sensitive goods, hazardous goods, general goods and bulk goods are established considering transportation cost, opportunity cost, risk cost and time losing cost. In the application of traffic assignment theory and transport path optimization method, the multi-transportation mode optionassignment model based on the generalized transportation cost of different types of goods is established, and Genetic Algorithm based on rational K-shortest path to solve the optimization mode is proposed. Finally, it takes the transportation organization mode optimization in the Three Gorges Region for empirical study ,the related suggestions and reasonable transport organization mode for main cargoes in Three Gorges areas are proposed, which provides valuable references for transport companies and cargo owners to take reasonable integrated transport organization mode.
