基于工作流驱动的航天产品分布式协同设计环境

摘要

A distributed collaboration design environment is proposed in this paper, based on the analysis of current aerospace products’ situation and problems. A sole defined and operated data source, Task Unified Model (TUM), is introduced in the coordinate design environment to commonly describe the knowledge, task, object, personnel and process. The definition of TUM, organization, views conversion and operation mechanism are detailed discussed. The distributed design environment, APEngine, is built on the basis of Eclipse RCP and Web Portal technology, which realized the TUM implementation, live example utilization and operation through the entire product design process. It has been proved in the design and utilization in an aerospace product that research work in this paper is highly useful in engineering application.%在分析目前航天产品研制面临形势和存在问题的基础上,引入了构建分布式协同设计环境的解决途径,同时针对产品协同设计过程中知识、任务、对象、人员和流程的统一描述问题,提出了协同设计环境中定义和运行的唯一数据源——任务统一模型(Task Unified Model,简称为TUM)的概念,并对TUM定义、组织、视图转换及运行机制进行了详细论述。然后基于Eclipse RCP和Web Portal技术构建了分布式协同设计环境APEngine,实现了面向产品设计全过程的 TUM 建模、实例化和运行过程。最后通过某航天历史型号设计的工程实际应用,证明了本文研究成果具有较强的工程应用价值。
