Product modeling methods in collaborative engineering environments

Thousands of advanced modeling tools have been developed for design and planning environments. Computer procedures and engineers work together in a comprehensive system where advanced tools are available for communication between procedures and humans. In recent years these software tools are continuously getting into the every day work of engineers. This paper focuses on the relations amongst the most important modeling procedures for mechanical engineers. The paper is organized as follows. First, the main groups of modeling activities are characterized from the point of view of concurrence and actual problems are outlined. Following this, the possible role of collaborative engineering methods is emphasized. Then an approach to concurrent modeling in a collaborative environment is proposed. Finally, the most important future development areas are considered.
