Research On Simulation And Optimization Of Container Multimodal Transport System

With the rapid development of economic globalization and regional information, container transport has been widely used by most countries in the world, and gradually formed a world container transportation system. As an advanced form of transport in organization transportation, container multimodal transport become the product and important symbol of the transportation modernization, and is also a general optimal mode of transportation of international trade. Since the 21st century, with the development of the international transport and speeded-up of the global economic integration, the position and role of the container multimodal transport in global transportation system has become increasingly prominent, container multimodal transport ushered in the period of rapid development, it has become the inevitable trend of the international trade of goods transport.However, the present construction of container multimodal transport system does not meet the requirements of rapid development of container transport; system construction relative lag in some extent hindered the development of container multimodal transport. In recent years, with the rapid development of import and export trade, the requirements of the logistics industry to accelerate the construction of container multimodal transport system have become more and more urgent. In the case of limited time and money, the optimization of container multimodal transport system with high efficiency low cost as the main characteristics is timely relief and the first choice to solve the problem of container transport.This thesis selects the topic under the macro environment of container multimodal transport developing leaps and bounds in our country. On the basis of reviewing of research on the current situation, it identifies their problems and proposes solutions to the above problems. The thesis takse container multimodal transport system as research object, which divided into three main components, namely:container multimodal transport cargo flow subsystem, container multimodal transport business process subsystem, container multimodal transport information flow subsystem. Firstly, against container multimodal transport cargo flow subsystem, it uses generation coefficient method to predict and simulate the container traffic of container multimodal transport system. Secondly, it takes railroad-sea transport as example to analyze the processes and modeling of container mutilmodel transport business process subsystem, and establishes a Petri Net model of container multimodal transport business process subsystem, and then executes simulation research under the environment of ExSpect. Finally, it discusses the application methods of container multimodal transport information system based on RFID, and the optimization of existing container multimodal transport business processes system.
