Human intent model assisted group work of design and manufacturing engineers

摘要

Advanced computer model based engineering activities produce model entities, their attribute values as well as associativity definitions as results of decisions of engineers. Later modifications and applications of models require information about the background of human decisions. Present day advanced modeling of mechanical systems do not involve techniques for this purpose. The authors investigated creation and exchange of design intent information. They proposed an extension to product models to describe design intent information. As a part of this work, 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, application of results of earlier research and the approach by the authors to describe design intent in product models are outlined. Then role of human-computer procedures in modeling of design intent is characterized. Following this, structure and entities in design intent model description are detailed. Finally design intent description in product modeling environment is discussed and illustrated by examples.
