A contribution to solution for the problem of human controlled object model definition

Virtual systems for definition, analysis and application of product models are widely applied in development, production, and application of products. These systems provide outstanding performance in description of product information. At the same time, any modification of earlier decided product information needs contribution from the original decision maker. Otherwise new decision is to be made while the original intent is not available. The authors conceptualized a new modeling method where human intent is stored in the product model as content of modeled information. This content is applied at new decision making. Some aspect of this new modeling is introduced in this paper starting with an introduction to model based product development. Following this, a method is shown for tracking affected engineering object chains by using of change affect zone (CAZ) definition. Next, the authors propose an information content extension to product model. They studied current information based product models, recognized conflict as caused by application of information based product modeling, and decided to complete the information based product model by information content based model. The conflict is in the communication between information based modeling procedures and information content based human. The proposed modeling can be implemented as an extension to functionality and model of professional product lifecycle management (PLM) systems.
