Research On Simulation Platform For Information Flow In Network Environments

Rapid growth in computer simulation technology,extensive attention has been paid to the simulation modeling technology in various fields such as national defense,logistics,industry and transportation.It is inevitable to use simulation modeling technology when analyzing and solving complex problems.Different requirements for simulation modeling software are proposed from different perspectives.Recently,various researches have been done in the field of information flow,which refers to the directional transmission of information between devices in a network environment.During the execution of the information flow,researchers focus on variation patterns and characteristics.The simulation modeling is focused on the process of information flow between systems,therefor new requirements for modeling software are proposed.It provides the information interaction model and verifies the correctness of the protocol design for the communication protocol between subsystems inside a complex system.This dissertation shows a graphical simulation modeling software which is focusing on information flow research to solve the problems of how to display connections between subsystems,directions of information flows and the interaction of information.To fulfill the requirements of information flow modeling,a simulation modeling software based on C/S architecture is designed and implemented.It mainly uses Java language for software development,and adopts the design mode of iterative development.Rapid prototype development is supported,the development platform is Eclipse,and the MVC design pattern is adopted,which benefits division of labor and cooperation among developers.The Mybatis framework is used for database interaction,and MySQL database is used to guarantee the security of data.The services implemented in system includes project management function,work surface function,canvas editing function,stand-alone creation and editing function,connection diagram editing function,static information flow diagram editing function,dynamic information flow diagram editing function,view message list,view parameter list and so on.It provides a simple and user-friendly interface for users.In order to reduce the database access pressure,the following strategies are adopted,to store the project files locally in the form of pictures or files,and store the relevant contents of messages or parameters in the database.In this dissertation,a simulation modeling platform is designed and implemented for information flow design.Firstly,the research background and significance of information flow simulation modeling platform are analyzed and introduced in detail.Secondly,briefly introduced the overseas and domestic research status,and expounds the work content of this paper.Combining the application background of the information flow simulation modeling platform and the practical problems solved,the work content of this paper is explained.This paper systematically introduces the related technologies Then it introduces the functional requirements of the information flow simulation modeling platform.These make the necessary preparations for the design and implementation of the platform.According to the in-depth discussion of software requirements,the overall architecture and functions of each module of the platform are defined,and the realization of each functional module of the platform is described in detail,and the actual operation interface is introduced.Finally,according to the test to verify whether there are defects in the platform,the function is in line with user expectations.At the end,the paper summarizes the work and explain the existing problems.
