Abstract In this paper, the authors propose a concept and method for management of changes of engineering objects during integrated modeling of products. The ultimate objective is development of intelligent model objects that include modeled object data and behavior description, and human intent filtered knowledge. The proposed model objects are intelligent organizers of information, knowledge, and procedures for decision assistance. Results facilitate completing present simple data, rule and formula based relating of parameters of modeled objects by an intelligent solution. The paper details application of integrated model object for the description of an interrelated group of modeled objects. Description of engineering objects is introduced. Following this, essential management of changes of modeled objects is shown. Next communication of changes in the affect zone of changed objects, is detailed. Finally, implementation of the proposed methodology as an extension of shape centered modeling of products and concept of the extended modeling systems are discussed as implementation issues.
