摘　　要：网格为仿真应用、资源共享和执行提供了一个理想服务平台,但只应用网格服务开发分布交互仿真,开发者必须自己创建通信机制来协调仿真执行。基于HLA开发的分布交互仿真存在缺乏动态发现和资源利用率不高等问题。为克服两者存在的问题并发挥各自的优点,提出了一种基于网格技术的HLA分布仿真实现方法。详细阐述了框架构成及网格服务构件和时序流程的设计,实现了仿真资源的动态分配、动态状态监控及任务动态迁移,并通过实验进行了验证。The Grid provides a service platform of coordinated resource sharing and application development and execution, however, developer had to establish communication mechanism by using grid service to develop distributed simulation. The HLA-based simulation is short of dynamic discovery and resource utilization. An implementation for HLA distributed simulation on the grid was proposed to overcome the defects of both technologies. A framework was proposed which described the design of Grid services components and scheduling of calling sequence. The problems of dynamic distribution of resource, dynamic monitoring of situation and dynamic migration of tasks were resolved, and an experiment was provided.
