方案设计两级实例推理过程模型及系统结构的研究

本文将重点研究机械方案创新设计过程。作者根据机械方案设计特点，提出两级实例推理过程模型，设计并描述基于实例功能推理的机械方案智能设计系统。同时对实例分解表示进行详细研究，并讨论了功能结构图及机械装置的框架表示方法，描述一种改进的组合功能分类方法，建立了方案功能结构实例库和机械装置实例库。

Research on Process Model and System Architecture of the Two-grade Case Based Reasoning for Conceptual Design

This paper emphasizes on the study of design process of mechanical conceptual.According to the character of mechanical conceptual design,the author presents a two-grade case based reasoning process model,and designs and describes a mechanical conceptual intelligent design system of case based function reasoning,and studies in details case decomposition representation and discusses function structure diagram and frame based representation approach to mechanical device,and describes an improved function classification method,and establishes a conceptual function structure diagram case base and mechanical device case base.
