多大元評価ベクトルを用いた基本設計における意思決定方法 : 工作機械主軸系の軸受形式選択への応用

The design procedure generally consists of many processes, from concept design to the release of parts and assembly drawings. Over all these procedures, designers always analyse various design requirements and conduct the information processing so as to have the most suitable result. Consequently, to rationally automatise such a design procedure, it is necessary to effectively process the design and its related information, e. g., decision making, by the computer system. In this paper, therefore, to establish a future CAD system of artificial intelligence type, the decision making in the basic layout design process of machine tools has been investigated and a decision making method using the multi-dimensional evaluation vectors has been proposed. The validity of the proposed decision making method has also been verified through the development of a system for selecting the suitable bearing type and arrangement for the main spindle bearing system from many candidates.
