Control of product object definition by background of human influence

Definition of product in model space includes contextual decisions and relies upon background of those decisions. This background influences decisions on engineering objects in a very complex way. Appropriately selected combination of engineering object variants may be a compromise in a coordinated product definition. The authors of this paper recognized that conventional model space construction in recent product lifecycle management has not model representation capabilities for the above background. Paper starts with a discussion about influences on product definition in the course of product development in model space. Following this, the currently prevailing and the proposed process of human influence are explained and compared. As the main contribution in the paper, methods for coordinated control of product definition, extended engineering object space, and coordinated change requests for adaptive action generation are introduced. Finally, execution of enabled adaptive action and implementation in PLM system are explained as implementation issues.
