On the way towards model for background of decisions on engineering objects in PLM

Abstract

This paper introduces a method for better communication between collaborating engineers and between engineer and entity generation processes at the definition of products in modeling systems. The authors recognized the importance of correct human-computer- human communication by using of product model as a special medium for engineers. In order to establish a product model that is appropriate for this purpose, they integrated all influencing effects on a product in an influencing space. In order to record content of influencing by engineers and other influencing persons, authorities, etc., the currently prevailing information based product model is completed by representation of information content. This paper emphasizes some relevant issues of information content. Definition of this contents starts from modeling of human intent. Intent model is consists of information about the owner of an intent, characteristics of that intent, and representation of content of intent in some form of knowledge. Information content is organized in the interconnected intent, behavior, and decision spaces. In a hierarchical system, intent space is at the highest and decision space is at the lowest level hierarchy assuring human intent based automation of decision making on engineering object in an improved product model.
