Research On Optimization Of Empty Container Allocation

With the globalization of economy, it is more and more obvious that container transportation plays an important role in the world trade. Along with this development, the empty reposition becomes barrier of developing further.This barrier arouses many scholars'interest, and they precede homologous research. But reviewing the current researching, the study of reposition optimization is still placed in the stage of determining the nature; there are seldom literatures which are dead against systematical and precise quantitative analysis. Shipping company still distributes the empties with the experience. Therefore, it is very difficult to operate economically without mathematics model of reposition.Along with the container transportation development, it is necessary to put forward theory, model and method to match the current transportation net's development. Furthermore, it is helpful to the development of ITS. From the angle of the shipping company and using the empty car distribution theories for reference, the optimization model which combined the qualitative analysis and the quantitative analysis is constructed for empty reposition, so that the optimization of routing, quantity and time is available. The contents and innovative points of this dissertation include:(1) Through studying the procedure of container delivery, the whole systems of empty reposition is assorted of the land-reposition and the sea-reposition. According to the component of this system, the demand and supply of empties, can minimize the transportation cost. Simultaneously, the cost of reposition is analyzed with the real example.(2) Analyzing the reposition with unconcerned situation and the random requirement in the land-reposition, a chance constrained model is constructed.(3) Researching the system of sea-reposition which is more complex than land-reposition. Therefore, the reposition which troubles shipping company longtime can be researched with quantitative analysis.
