基于HLA的复杂产品协同设计环境

为了实现复杂产品协同设计中的数据一致性、互操作性和冲突消解,建立了一种基于高层体系结构(HLA)的协同设计环境体系框架,定义了3类具有不同权限和职能的联邦成员:设计邦员、管理邦员和监测邦员.在系统框架的基础上,给出了各邦员的时间管理策略和联邦的总体时间推进过程,以及运用邦员的项目权限和所有权管理服务实现发言权控制,确保邦员接收数据的一致性和事件的时序性,避免了冲突操作的发生,并给出原型系统实现的功能和具体应用方案.

Collaborative Design Environment for Complex Product Based on HLA

In order to implement data consistency,interoperability and to resolve conflicts in collaborative design for complex product,a system architecture based on HLA for collaborative design environment was constructed.Design federate,management federate and monitoring federate with different authorities and functions were defined respectively.Based on the architecture,time management strategy of every federate and global time advancing process of the federation were introduced.Meanwhile,the implement process of floor control by utilizing federate authority and ownership management service was described particularly. Using the methods above,data consistency and event time sequence are ensured,and conflict operations are effectively avoided.Finally,the prototype system and application scheme were provided.
