Research On Information Organization And Interface Standardization Of Commercial Vehicle Dispatch System

At present, almost all the Logistics Company in China dispatch vehicle by human. It is not only low efficiency and high cost, but also restricted by workers. In order to improve the efficient, reduce the cost and make good use of society resources, Beijing University of Technology make the research of Key technology of Vehicle Routing Problem and set up the Commercial Vehicle Dispatch System (CVDS) base on Internet supported by Beijing Science and Technology Committee. Good organization, describe and standardize the information and interface are very important, because this system involves enormous information, and it will interchange information frequently between the system and environment and also between the sub-systems. In this reason, this thesis makes study of organization and standardize of CVDS information and interface.At the beginning of this thesis, the research of organization and standardize to vehicle dispatch information and interface is reviewed, at the same time, the theory about information organization and standardize is introduced. There is no research in China and other countries about it, so it is very necessary and urgent to do it. After understand and apply the theory related, the method of this research is decided, that is, organizing the information of CVDS by systematic, and describing and standardizing the information and interface by eXtensible Markup Language (XML).The organization of information and interface are related to the system structure closely, so the structure of CVDS is described briefly, and also the relation between the system and environment. At the same time, the sub-system is divided according to different function. After this, the information that every sub-system needed is analyzed and induced, then all the information of this system involved is achieved after sum up. Using systematic method and information organization theory, the information of CVDS is induced and classified according the structure and function of the system, that is, user information, distribution center information, business information, daily dispatch information, emergency dispatch information and geography data information. After analyzing the flow of system information, the direction and contents of information between each two sub-systems, and effective organization to information and interface is decided too. The last part of this thesis is to describe and standardize the organized information and interface by computer language. eXtensible Markup Language (XML) is adopted. After constructing reasonable system structure according system needed, complete XML Schema structure model file and interface model file are compiled by use of XMLSpy software. The reasonable organization and effective calling to CVDS information are realized by this research, this is also an application study for XML, which is in the...
