Abstract
The purpose of this paper is to show the common basis of several object-oriented design modeling principles as compared with those used in classification and coding (C&C) for group technology applications. Five types of decision tree (E-trees, N-trees, X-trees, D-trees, and C-trees) are shown to be in exact correspondence with the object-oriented modeling principles generalization with disjoint subclasses, generalization with overlapping subclasses, classification, generalization with restriction, and aggregation, respectively. In addition, C&C modeling and subsequent database implementation are shown to be enhanced through application of such object-oriented modeling principles as association and role names. Finally, a case study is presented that illustrates the application of these principles in the design and implementation of a C&C system for abrasive flow machining.
