RTI属性数据交换机理建模与分析

摘要

Aiming at the problems that RTI (run-time infrastructure) performance test indexes can not effectively support the RTI performance optimization of RTI and the optimal design of HLA (high level architecture) federation,the RTI performance study was conducted from the view of RTI data exchange mechanism.According to the queuing network theory,the process of attribute data exchange was analyzed,and a RTI attribute data exchange mechanism model was proposed,and it was implemented based on the colored Petri net.The model has its better flexibility and extensibility,and it indicates the deepening and extending of the RTI performance study.The experimental results show the model is feasible and effective.%针对运行时支撑环境(RTI)性能测试指标难以有效支持RTI性能优化和高层体系结构(HLA)联邦优化设计的问题,从RTI数据交换机理角度对RTI性能进行了研究.基于排队网络理论,分析了RTI属性数据交换过程,建立了交换机理模型,并给出了基于着色Petri网(CPN)的仿真实现模型.RTI属性数据交换机理模型是RTI性能研究的深化和扩展,具有较好的灵活性和可扩展性.实验结果验证了模型的可行性和有效性.
