Composite objects and dependency relationships in Engineering

This paper depicts two important relationships required for CAD/CAM applications. The first one is the composition relationship between a pair of objects (a set of objects related by the composition relationship is collectively called a composite object). The second one presents the semantics of Dependency between two objects. Within the Knowledge Based Systems like YAFOOL, LOOPS and ORION, the semantics of composition and dependency relationship suffers from a number of serious shortcomings. Our Knowledge Based System, SHOOD, will provide a rich semantics of composition and dependency relationship which mitigates these shortcomings in a consistent and convenient fashion. This work is a part of fully developed scheme for composite object and dependency relationship management.
