Abstract: The concept,system infromation module and character of SOD(Simulation on Demand)are introduced in this paper.Then a detailed discussion is made for WWW-based SOD mechanism．It is presented that modern object－oriented programming languages are combined with intelligent agent techhologies and used to solve the key problem of SOD system such as time synchromzation,object-independent interobject communication,event handing and observation and control of simulation objects,etc.
