A new method for enhanced information content in product model

Abstract

Abstract- This paper introduces a new method in order to establish a better communication between engineers and modeling procedures during lifecycle management of product information in computer based engineering systems. The proposed method is intended as one of the initial attempts for resolution of an inherent conflict in product modeling. This conflict is between information content based thinking of engineer and data based processing in classical product modeling systems. The author applies a new sector of product model that describes information content for engineering activities. This sector controls engineering object data in the second sector for classical product model entities. In this manner, the new modeling can be interconnected with existing modeling in industrially applied engineering systems. Information content is stored in interconnected levels of the product model for human intent, meaning of concepts, engineering objectives, contexts, and decisions. This paper explains basic concepts, refers to research in the related topics, introduces role of humans and human-computer interactions in the proposed modeling, and details information content based product modeling. Following this, it emphasizes difficulties of decisions in case of high number of dependencies amongst engineering objects in large product models and proposes a new method for change management in those models. Implementation of the proposed product modeling methods can be realized in industrial professional modeling systems by using of their functionality for open architecture.
