摘要由于其在确定产品的基本特征和开发成本中的作用，概念设计与基本设计或细节设计的相对意义得到了广泛的认可。尽管有一些通用方法在设计设计中的功能，但实际上，没有商业CAD系统可以支持功能设计，特别是设计的合成阶段。支持概念设计的合成阶段是具有功能建模功能的CAD系统的关键问题之一。在本文中，我们提出了一种称为功能行为状态（FBS）建模器的计算机工具，不仅在分析阶段，而且在合成阶段都支持功能设计。为此，建模者知识库中的功能分解知识和物理特征，以及子系统定性过程绑架系统（QPA）扮演着重要角色。描述了与FBS建模者中概念设计的行为，结构和设计过程相关的功能方案。 FBS Modeler的优势是通过呈现两个示例来证明的。也就是说，设计师使用此工具以及功能多余的机器设计的实验，这是用于高度可靠机器的新设计方法，作为其应用。
Abstract The relative significance of conceptual design to basic design or detail design is widely recognized, due to its influential roles in determining the product's fundamental features and development costs. Although there are some general methodologies dealing with functions in design, virtually no commercial CAD systems can support functional design, in particular so-called synthetic phase of design. Supporting the synthetic phase of conceptual design is one of the crucial issues of CAD systems with function modeling capabilities. In this paper, we propose a computer tool called a Function-Behavior-State (FBS) Modeler to support functional design not only in the analytical phase but also in the synthetic phase. To do so, the functional decomposition knowledge and physical features in the knowledge base of the modeler, and a subsystem Qualitative Process Abduction System (QPAS) play crucial roles. Modeling scheme of function in relation with behavior and structure and design process for conceptual design in the FBS Modeler are described. The advantages of the FBS Modeler are demonstrated by presenting two examples; namely, an experiment in which designers used this tool and the design of functionally redundant machines, which is a new design methodology for highly reliable machines, as its application.
