Optimization On Transportation Capacity Resource Allocation Of China’s Railway Based On Tripartite Game

ABSTRACT:In recent years, rail transport is playing an increasingly important role in our domestic transportation system with the development of our economy and economic restructuring. However, the overall transport capacity resources cannot meet the demand of transportation during the past long period of time. Formerly, the resource allocation of rail transport has focused on accomplishing the transportation task as much as possible. During the past few years, high-speed railways have been successively coming into operation, which largely alleviated the shortage of transport capacity resources. As the transportation organizational conditions of China’s railway are changing radically, the traditional organizational model cannot adapt to the optimal allocation of transport resources. In order to promote the total revenue of rail transport operations and service levels, an optimal allocation method of transport capacity resources is urgently needed to be carried out under the new transport organizational mode.Most of the existing allocation models are mainly focusing on passenger allocation, which ignore the cargo transport allocation in the whole transportation organization. There are few allocation models which take passenger and cargo transportation both into consideration, but the passenger transfer rate between a passenger dedicated line and an existing ordinary passenger line is not integrated into the model. This thesis constructs a pervasive optimization model of railway transport resource allocation based on Tripartite Game under the new mode of transportation organization, by applying system science, operations research and other related basic theories. Therefore, the cooperating value among high-speed passenger dedicated lines, ordinary passenger trains and cargo trains are excavated. Genetic Algorithm is used in solving the model, so that an optimizing allocation scheme can be obtained in order to promote the integrated profit and service level of railway department.Wuhan-Guangzhou railway transportation network is taken as an example to verify the validity of the model. The results show that this model can promote the allocation of railway resources on a large scale. Under the premise of not affecting passenger services, the transport capacity of existing lines is abundantly released so that the railway department can provide better cargo services. This thesis aims to provide a reference and basis for allocating transport resources for the railway sector through this model and validation.
