The Design And Implementation Of Simulation Scenario Editor System Based On XML

Simulation technology has been an effective tool for the analysis of practical problems.With the development of science and technology,the requirement of simulation technology is becoming more and more urgent.However,for the complex reality,the general simulation technology can not complete the simulation experiments according to the actual situation due to its simple design.Simulation scenario editing system makes use of modern computer technology to simulate the complex problems in reality,so that people can easily analyze complex practical problems,and then to improve or solve the problem.The simulation scenario contains a wealth of content,and the design is more complex,the general simulation scenario system is designed to solve the special problems,and the reusability and practicability is poor,which makes the utilization of the simulation system is low.In view of the above problems,this paper designs a simulation scenario system with high availability and convenient operation.According to the simulation scenario editing system of the background and the research status at home and abroad,we put forward the content of the thesis;Based on the concept and description method of scenario,we select XML as the description language of scenario due to its advantage in scenario description,and research the key technology which can contribute to the realization of simulation scenario system;The functional requirements of the simulation scenario editing system are analyzed,the use case diagram is used to model the use case,and the data flow diagram is used to process the model;We present the hierarchical architecture and flow of the simulation scenario editing system,and detailedly expound the design and implementation of each functional module;We propose a mapping method to format Schema to XML,and use XML Schema to constrain grammar,so as to achieve the XML document to be accurate,unambiguous description;This paper analyzes the storage design of the data file,and based on the fact that we need to query and modify the file,the system uses the way to store the XML file in the local file system.The simulation results show that the designed simulation scenario editing system is stable.According to the pre-design,the system realizes the function of setting,modifying and deleting the scene files,realizes the function of setting to each attribute,and realizes the function of deduction.The realized function of each module achieve the desired design goal of the system.
