RATIONALE "Maher, CBR in Design survey" M. L. Maher & A. Gomez de Silva Garza (Mar/Apr 1997) Case-based reasoning in design, IEEE Expert, Volume 12, Issue 2 pp. 34-41. This survey reviews CBR and how it can be used in design systems. At one extreme, cases are selected for use by human users, and at the other the design process is automated. Issues discussed include what a case can be, how to index cases, and how to modify cases to fit the current situation.
