Study On Optimization Of Multimodal Transport Base On Diversity Of Consumer's Demand

With the booming development of the economy and logistics, the world picked a upsurge of multimodal transport development. As its own advantages, the international transport plays an increasingly important role. However, from China and even the world multimodal transport process, the multimodal transport although is international transportation irreversible development direction, but its developing process has many problems:in macroscopic, a few developed countries multimodal transport development is rapid, but most of the developing countries development is slow and even stagnation. Due to the cause international multimodal transport development is not balanced; in microscopic, base on diversity of consumer's demand, most of the carriers are not well understood multimodal transport link, and lack of reasonable arrangements of multi-modal path causes the high multimodal transport cost and seriously influence multimodal transport development. This thesis research optimization problem of multimodal transport base on diversity of consumer's demand, and hope that the research will play a positive role on development of the multimodal transport.In chapter 1, this paper summarizes the multimodal transport development course, trend and significance, researches the current domestic and international multimodal transport items, and the various representative research methods.The second chapter gives the concept of multimodal transport and container multimodal transport characteristics and superiority, also discusses the multimodal transport development situation of the advanced developed countries. In chapter 3, analyzes the diversity of consumer's demand base on AHP. In chapter 4 through several typical optimization model analyzes own optimization model and designs algorithm based on c++ programming. In the fifth chapter made a empirical research.According to this thesis's analysis and the domestic research of actual situation of multimodal transport, Due to the intermodal optimization situation of our country, the optimized objectives is comprehensive value of shipping costs and time. the constraints including capacity constraint, time constraint and reasonable assumptions constitutes the advanced multimodal transport optimization model structure of our country. This structure system is based on the diversity of consumer's demand, requirements of different consumers for cost and time are not identical, this situation cause that not give a single performance with cost or time as optimized object, but consider the comprehensive value of cost and time. The complicated structure of optimization model makes traditional solving methods (such as: genetic algorithm, the ant colony algorithm) hard to design and solution, so we adopts the graphical theory, through the C++ programming model provides an effective method for decision.
