Adaptive objects for behavior based product models

Product design, analysis, and manufacturing planning activities in engineering modeling result model object describing engineering objects. Modification of one of the modeled objects needs modification of one or more modeled objects or one or more model objects do not allow it. The authors in this paper propose environment adaptive model objects for tracking the effects of modification of an existing object or definition of a new object on the basis of existing objects. The necessary modifications are enforced or cancelled. In other words, the modeling system analyses all consequences of a modification in an integrated model. To do this, the proposed objects have the capability of description of mutual effects of a modeled object and objects in its environment. They carry and interpret knowledge necessary for revision of earlier decisions. The paper outlines a concept for engineering design using intelligent model objects. Then basic information and functional structure of the proposed model objects are explained. Following this, mutual effects of modeled objects and their environments are analyzed and relationships within a model object are discussed. Finally, utilization of design intent descriptions in models of engineering object to solve adaptivity-related problems is analyzed.
