设计与计算的双向集成

Bi-directional integration of design and calculation

在CAD系统与计算程序协同工作中发生的数据交换,应理想地沿两个方向进行,以支持产品开发过程,这通常称为"双向数据交换".然而,如何对此概念准确理解,学术界在表述上都不尽相同.原本意义上的单向数据交换,可以按序反向地进行,而被说成是"双向"的.这样,在一种事实上每时每刻都沿双向进行的数据交换之外,还存在一个相同的提法.然而,这两种方案有根本区别的.由此,对概念进行区分,并指出其差别.

In support of the product development process the data flow between CAD and calculation systems should be enabled in both directions. The common term for this topic is 'bi\|directional data flow'. But even in professional circles the usage of this term is equivocal. A unidirectional data flow can be specified 'bi\|directional' if it's done sequentially and counterdirectionally. In this case it is notional equal to a real bi\|directional data flow that is done continuously. Both approaches mentioned are fundamentally different. The article distinguishes the term 'bi\|directional' and points out the differences.
