项目摘要

This research has been done with the purpose of constructing Knowledge information processing systems to support conceptual design tasks.Main results are summarized as follows :1. By introducing the functional analysis methods in Value Engineering, a way of analyzing designed objects from the teleological, causal and economical rationalities, which result in multilayered modeling of designed objects.2. Based on this method of analysis and a machine learning method called Explanation-Based Generalization, a way of acquiring varied design knowledge from designed objects is introduced and implemented using a logic programming language.3. The operationality of the acquired knowledge is analyzed in relation to the mode of knowledge acquisition, by which we can find the most suited phase of design for each piece of the acquired knowledge.4. Based on the idea of Axiomatic Design Approach, the above knowledge acquisition system is extended so that it can also extract strategic design knowledge from the analyses of designed objects, by which design processed are efficiently guired.5. A way of searching and indexing for the above acquired knowledge is introduced by referring to the methods of Explanation-Based Generalization and Case-Based Reasoning. Also, a way of modifying and combining designed objects is introduced in relation to design requirements.6. In order to build effective human interfaces for the support system, a representational method of modification and combination of design models is introduced, by which a designer (user) can grasp the essential effects of modification and the consistency of the combination.

这项研究的目的是构建知识信息处理系统以支持概念设计任务。结果总结如下：1。通过引入价值工程中的功能分析方法，这是分析目的论，因果和经济合理性的设计对象的一种方式，从而导致设计对象的多层建模。2。基于这种分析方法和一种称为基于解释的概括的机器学习方法，使用逻辑编程语言介绍和实现了从设计对象获取各种设计知识的方法。3。根据知识获取方式分析了获得的知识的运作，我们可以找到最适合的设计阶段的每个获取知识。4。基于公理设计方法的思想，上述知识采集系统也可以扩展，以便它还可以从设计对象的分析中提取战略设计知识，而设计对象进行了有效的设计。5。通过参考基于解释的概括和基于案例的推理的方法来介绍一种搜索和索引上述知识的方式。此外，与设计要求有关修改和组合设计对象的一种方法。6。为了为支持系统构建有效的人类界面，引入了设计模型的修改和组合的代表性方法，设计师（用户）可以掌握修改的基本效果和组合的一致性。
