Abstract: | Knowledge acquisition has always been the bottleneck of artificial intelligence. It is the critical point in product family design. Here a knowledge acquisition method was introduced based on scenario model and repository grid and attribute ordering table technology. This method acquired knowledge through providing product design cases to expert, and recording the means and knowledge used by the expert to describe and resolve problems. It used object to express design entity, used scenario to describe the design process, used Event-Condition-Action (ECA) rule to drive design process, and with the help of repository grid and attribute ordering table technology to acquire design knowledge. It's a good way to capture explicit and implicit knowledge. And its validity is proved with respective examples. |
