摘要
以一个协同集成设计环境的计算机辅助工具为背景 ,对任务机制进行研究。首先提出了一种协作任务模型 ,用于描述设计对象、通讯支持、设计主体及其角色之间的内在联系。然后提出了体现运行时任务、用户、CAD数据文档之间逻辑关系的多任务结构 ,并构造了一个支持建立这种结构的任务向导流程。最后 ,研究了多任务的通讯支持技术 ,包括静态配置的全局任务信息服务器和面向任务动态配置的通讯转发服务器。工程实践表明 ,这些模型、结构、流程和技术方法是正确合理的 。
A case study of cooperative task in Computer-Aided Tools for Collaborative Integrated Design Environment (CATCIDE) was discussed. Firstly, a cooperative task model was established. The model integrated the design objects, communication supporting, designers and their roles in a way of collaboration-awareness. Secondly, a dynamic multi-task structure which describes the logical context of tasks, users, CAD data documents was presented. A task wizard was produced to build the multi-task structure at run time. Finally, in order to utilize the existing communication resources, the multi-task structure configured a static task information server and several task-oriented dynamic messages forwarding servers in CATCIDE framework. The results demonstrated the model,structure and process have more powerful and flexible task functions than application sharing tools.
