基于渐进式虚拟原型的并行设计方法

现有的并行设计多采用基于知识的方法和基于约束的方法，它们要求必须有明确的问题表述，并且缺乏对概念设计正确性的确认手段，因此难以适应创新设计的要求，应用范围有限．针对上述问题，给出了渐进式虚拟原型的概念，用原型树模型刻画了渐进式虚拟原型的构成方式和进化过程，并在螺旋模型的基础上，提出了基于渐进式虚拟原型的并行设计方法．该方法可以有效地减少大的设计过程反复，提高设计活动的并行度．基于已开发的并行设计环境，该方法已经应用到实际的设计中，并发挥了重要的作用。

Concurrent Design Methodology Based on the Incremental Virtual Prototyping

The incremental evolving process of a product under virtual development is represented by a tree-like-model named virtual prototyping tree. Design teams with different majors work together around the tree to materialize the conceptual design and improve its performance progressively in a spiral way. Such an approach can avoid the long lasting try-and-error process of product development and highly effectively utilize the joint efforts of teams. The concurrent design environment established in such a way has been verified successfully in a real project.
