A distributed simulation system and its application

Distributed systems offer flexible computational power, which can be applied to larger systems that need to evolve rapidly. Based on the concept of grid computing, the paper designed and developed a distributed simulation system named DSoG with the responsiveness of locally autonomous sub-systems where each participant defined behavior and their relationships with others. Based on multi-layer decomposition, the distributed simulation system introduced was generic enough to allow the description of divers applications, while different levels of detail were also supported. DSoG provided a flexible environment for defining, modifying and simulating the component-based aero gas turbine models, and enables users to customize and extend the framework to add new functionality or adapt simulation behavior as required. At last, a distributed aero engine model was constructed and simulated to illustrate the use of the system.
