Bringing up product model to thinking of engineer

Effectiveness of an engineering process in product modeling is determined by modeling system capability in representation of elements from the human thinking process during decision making on strongly interrelated engineering objects. Engineering objects are not only objects in the product structure but also include objects for product related activities such as analysis, manufacturing and production. Current product modeling systems apply the well-proven information based modeling and model in order to assist product related engineering activities in the industry. The authors analyzed this classical modeling and developed a modeling methodology to improve communication between engineer and information based modeling procedures. The proposed methodology is also aimed to enhance indirect communication between engineers by using of the product model as medium. In this paper, thinking process of human for product definition, information content based modeling, changed application of knowledge, and restricted automation of engineering decision processes are discussed. A comparison of information and information content based product modeling methods is given. In addition to enhanced human-computer and human-human communication, higher level of automation in product related engineering mainly in decision making is also discussed.
