Abstract: To improve reusability of module knowledge and module reconfigurability, aiming at the module design system which couldn't make full reuse of knowledge of module design case, a reconfigurable module design method oriented to networked case based reasoning was proposed. According to this method, the networked case searching mechanism based on module design case was put forward. In this searching method, module was described by using unified data structure. Feature attribute of module was dynamically reduced and weight was computed by fuzzy rough set. The appropriate design case was found by the module similarity computation. Based on parametric modules, needed module was obtained by case reconfiguration. A networked module design system based on case based reasoning was developed in a packaging machinery enterprise. And the networked reconfigurable module design based on case was realized.

Key words: case based reasoning, networked module, reconfigurability, reusability, similarity, case searching
