Case Based Reasoning in Engineering Design
Abstract
Case-Based Problem Solving is based on the idea that problem solving should re-use solutions and other information from previously solved problems instead of relying solely on a base of procedures or rules. The researchers presented a case-based design system, CADET retrieves and re-uses previous successful designs while avoiding previous failures such as poor materials or high cost. The system uses certain behavior-preserving transformation techniques to transform an abstract description of the desired behavior of the device into a description that can be used to find relevant designs in memory. This approach, in effect, decomposes given behavior specifications into 'sub- behaviors', making it possible to recognize parts of previous designs that can be synthesized to form a new device. Currently, the system can perform conceptual design of mechanical devices that exhibit continuous and reciprocating behavior. In addition, since CADET can generate a wide variety of behaviorally equivalent alternative designs for a given set of design specifications, it can be used as a designer's brainstorming assistant.
