Integration of Human Intent Model Descriptions in Product Models

摘要

Advanced product model based style of engineering design together with internet based globalized project work relies upon advanced communication of model data. Model entities and their parameters represent decisions of engineers. Present day models of mechanical systems do not contain data about the background of human decisions. This situation motivated the authors at their investigations on exchange design intent information between engineers. Their concept was extending of product models to be capable to describe design intent information. Several human-computer and human-human communication issues were also considered. The complex communication problem has been divided into four sub-problems, namely communication of human intent source with the computer system, representation of human intent, exchange of intent data between modeling procedures and communication of the represented intent with humans. The paper is structured as follows. Firstly, main objectives of the research, earlier results and an approach to describe design intent in product models are outlined. Following this, utilization of human-computer procedures in modeling of design intent is characterized. Then main structure of model description of design intent is detailed. Finally design intent description in product modeling environment, is discussed and illustrated by examples.
