并行工程中的三域原理及其体系结构研究

针对CE的体系结构及其实施过程中的两类支持问题，通过对CE基本理论的研究，建立了以支撑域、执行域和管理域三域为基础的CE体系结构，使CE的实施不仅有一个基本的支持环境，而且从组织管理上确保其严格按CE的基本原理进行，为解决CE关于一体化，并行设计的组织管理问题，提出了CE的微观串行宏观并行原理，并建立了相应的CE螺旋模型，对基于三域原理的CE体系结构的应如信息集成框架，面向对Internet/Intranet的应用和实施以及与企业环境的融合也进行了研究。

Three-Domain Principle Suggested for Concurrent Engineering (CE)

We deem that the study of CE (concurrent engineering) theory and CE technology as a whole has been very inadequate and thus handicaps the further development of CE. In section 2, we discuss in much detail our suggestion of three domain principle for CE. The three domains are domain support, domain implementing and domain management. Domain support provides all the necessary support for CE implementing. Domain implementing considers all the activities of product life cycle. Domain management assures that the implementing of CE is by CE theory and method. Figs.1 and 2 taken together give the CE system structure based on three domain principle. Fig.3 gives a CE spiral model, which is helpful to the better planning of all activities even though, in reality, in product life cycle, the activities are done in series, i.e., the last activity has just finished and the next activity is yet to begin.
