Analysis and Design of Simulation Training System for Disaster Relief Material Support

Computer simulation training is an important method for enhancing capability of emergency support in disaster relief.Simulation training system for material supply is analyzed and designed on the basis of combining modeling and simulation technology.Functional requirements of that system are proposed.The main functions include supply operation,distributed interactive cooperation,models management and optimization,data management,process advancing and supply flow control.A three-layered system structure is analyzed.The infrastructure layer is composed of command system,directing and control system and RTI(Run Time Infrastructure).The resource layer is composed of model base,knowledge base and database.And the application layer is composed of five simulation training sub-systems which are related to living,camping,medical treatment,engineering and equipment.Designing flow of simulation models based on technology of combining modeling and simulation is given.The distributed system design based on HLA is completed.Four kinds of federates for material supply in emergent disaster are constructed.FOM(Federation Object Model) and SOM(Simulation Object Model) are designed.And the interfaces between Agent-DEVS federate and RTI are devised.These efforts lay the foundation for development of simulation training on services of emergent disaster.
