CONSTRAINT-BASED RETRIEVAL OF ENGINEERING DESIGN CASES Context as constraints
Taner Bi̇lgi̇ç, Mark S. Fox · 1996
. The case-based retrieval is frequently reported as a valuable tool for engineering design. We discuss similarity based retrieval in the engineering design domain when the context is given as a set of constraints. This approach comprises the lowest level with which we support case-based retrieval from our Integrated Knowledge-Base. The characterization of the retrieval process yields a robust compliance measure and a similarity measure for the cases in a given context. The problematic concept of context is taken up front by making it an explicit part of the query. 1. Introduction Engineeringdesign involves usage of domain specific technical knowledge together with creative problem solving skills to come up with a properly functioning artifact that complies with a set of requirements --- performance goals, physical constraints, etc. It is a creative process that relies heavily upon associations to past experiences and similar designs (Goel, 1994). Consequently case-based reasoning (CB...
