Research Of Operation Simulation Models And Their Running Architecture

Model is the foundation of system simulation. A great deal of models spring out with the development of Model and Simulation(M&S). How to make use of the current models and avoid developing models repeatedly is a concerned question. The thesis imports Web Services to model description and researches on model inter-operation and reusable. It puts forward the simulation running architecture based on service.The thesis regards model as a service and descripts model attributes, methods,structure and interaction by Web Services Description Language.It achieves models'inter-operation by services request suppied.When using model'services,we only need to know the URL and the transferring style of the model,but need not to know the model's codes and environment. By this means, we can reuse the model.The thesis improves the simulation running system that orients RTI. The improed simulation system can meet the need of cosmical simulation. The great mass of entity models and federates come from the Wide Area Network (WAN) when we develop simulation systems.The thesis puts forward the concept of Representative Federate,the Representative Federate stores the federate's attributes and interaction parameters. The Federate Proxy interacts with other federates in different simulation platforms. The federate communicate its proxy through a service management module.The service management takes charge of communication between different platforms, it send the interaction parameters and the new attributes to Federate Proxy that distribute in different platforms.Finally, the thesis designs a simulation running process and particularly discusses the process of attributes update and interaction sending.It discusses the simulation running process through an operation scenario.
