摘　　要：研究高层体系结构优化管理服务问题,其中HLA接口规范中的所有权管理是基于对象的属性,针对不能支持对象所有权的转移技术。在某些时刻中,若能给对象所有权的转移会给分布式仿真应用带来更大的便捷。为了解决上述问题,引入了一种特殊的管理平台,在充分利用已有HLA为分布式仿真提供的所有权管理服务的基础上,集中式管理成员对象实例的公布订购关系以及对象实例与成员之间的所属关系,实现联邦成员对象所有权的动态、快速、安全转移实验。结果表明,管理平台在不改变原有RTI架构的基础上,完成了对象实体级别的自动化迁移,拓展了交互式仿真应用范围,优化的管理服务权限。The ownership management in the interface specification of HLA is based on the attribute of object,but there is no guaranty at object ownership transfer.In some cases,using ownership migration,federates with limited capacity can dispose the responsibility to update attributes,so object ownership transfer will facilitate distributed simulations using HLA.In the paper,a new special management platform was introduced,making use of established ownership management services provided by HLA to supervise the publication/subscription relationships of federate object and belongingness between federate and object,which made dynamic,quick,safe transfer of object come true and expanded the implement area of the interaction simulation.Experiment results show that the platform proposes an expanded set of services that allows the transfer of complete objects between federates,which expands the extension of interactive simulation application.
