Research And Implementation Of Simulation Manager In The Distributed Virtual Naval Battle

Distributed Virtual Battle is combination of technology of Simulation, Virtual Reality, Computer Network Man-Machine Interaction and tactics through which distributed users can communicate, cooperate and antagonize with each other, and it also accomplish the simulation of complicated campaigns. Simulation management is one of the most important parts in Distributed Virtual Battle, which is mainly composed of scenario edit, real-time situation display, simulation logging and playback,and evaluation of the result of the simulation.The thesis analyze and realize the three parts of simulation management at the base of analyzing the requirements of Distributed Virtual Naval Battle.The primary work includes: The thesis design and realize the Simulation Scenario Editor and the tow-dimension Simulation Situation Display which are base on disgital chart.The Simulation Scenario Editor can support the deployment of both forces in the simulation ,the set of environment efficiently according to the simulation scenario.It has good effect.The two_dimension Simulation situation display receive simulation data and display the movement and dynamic changes of entities of both forces according to the data structure of military label in this theis. The thesis analyze the differences among three kind of architecture of logging and playback in HLA/RTI,and present a way to record simulation data which use binary file and database,and which is suit for playback and analysis after simulation.The thesis also study some problems in loggine and playback,realize the central logging and playback. The basic way and indexes of evaluation of effectiveness is studyed.The thsis present an algorithm of evaluation which use the data recorded by simulation logger and exponential way.and finish the analysis after action using the data in logging database.At last, the primary work is summarized, and some future works are stated.
