Simulation Operation Control is the key technology of simulation running support platform. Large complex simulation test need to deploy every test node reasonably on the normal implementation terminal. In order to meet the requirements of distributed network communication, this article provides a HLA Network Based Simulation Operation Control Method based on HLA distributed network communication protocol. This method designed Simulation Engine based on six standard service of HLA, it include many functions on object management, test scheduling and event management and so on. It implementa distributed deployment of terminal nodes in considered load capacity of terminal. In the course of simulation test operation, it can dynamically real-time monitor operating conditions and member information and improve efficiency on simulation test.
