Abstract: The main purpose of this paper is an introduction of an application of Petri net model entity representations in concurrent engineering processes. Characteristics of the proposed modeling include feature based and multiple level model structure, generic model entities and an integrated modeling approach. The authors have developed a manufacturing process modeling approach and methodology that is suitable for continuous modification of part manufacturing processes on the basis of messages about changes of part models and other conditions. Generic manufacturing models involve variants. Entities in the model are represented by Petri nets that can be repeatedly executed for changing conditions The method assumes a reorderable form feature based part model. The paper is organized as follows. First, the related and actual issues of concurrent engineering and their relations process modeling are outlined. Following this, the proposed approach and the methodology of integration feature based part models with part manufacturing models are explained. Next, application of the proposed integrated modeling in concurrent engineering processes is detailed. Finally, possible benefits of the proposed model in present day modeling are discussed.
