工学解析モデリングのための知識管理フレームワークについての考察(<小特集>第18回設計工学・システム部門講演会) Research on Knowledge Management Framework for Engineering Analysis Modeling(<Special Issue>18th Design & Systems Conference)
Any engineering analysis model is indispensable to predict the behavior of a product for its rational evaluation and optimization. In the process of modeling engineering analysis, an engineer makes model idealizations, which depend on a various factors of design such as the kinds or types of products, the objectives of the engineering analysis, and design leadtime constraints. Because the knowledge of engineering analysis exists in modeling process, it is important to capture and manage the modeling process for enhancement of rationality and reusability of engineering analysis models. This research aims to develop the knowledge management framework for engineering analysis modeling. This paper proposes a concise and comprehensive description format of modeling process called Engineering Analysis Modeling Matrix (EAMM). Three modeling levels, i.e., conceptual model, mathematical model and computational model, three modeling aspects, i.e., target objects, governing principles and behavior, and seven modeling operations are defined as fundamental terms of modeling process. A modeling example of heater analysis shows the EAMM's capability as a foundation of the management framework of engineering analysis modeling knowledge.
