Abstract
Modeling of products in engineering systems for lifecycle management of product information has reached a level where all product related information can be integrated in a single but large and very complex product model. In order to develop well-organized systems and application specific protocols for the construction of product model, an ISO standard provides global platform. The authors analyzed inherent problems with current product modeling and proposed new modeling methods in order to handle them. This paper introduces some of these methods. It starts with a discussion about functions and role of human intent at product definition in modeling systems. Following this, the problem posed by high number of unorganized relationships is emphasized and a new method is proposed for their handling. Rest of the paper is devoted to a second problem of human-computer interaction in case of information based current product models. In order to improve the communication between human thinking and model information generation processes, a new information content based extension is proposed to the currently prevailing product models.
