Constraints conflict occurs inevitably in collaborative design process. Therefore, conflict detection and resolution becomes critical for successfully completing the design. This paper puts forward a novel process of constraints conflict visualization to help designers to solve the problem. The process begins with modeling of constraint information based on constraints satisfaction problem (CSP),...
Task partition is a critical problem of collaborative conceptual design. Aiming at the shortage that current task partition methods don't accord to innovative functional reasoning that is the kernel process and essence embodiment of conceptual design, a new task partition method for function tree according to innovative functional reasoning is proposed. To begin with, the concept of task module is...
Reasonable task planning is the key technique to improve cooperation quality and the design efficiency in collaborative design. This paper proposes the concept of Task Precedence Graph (TPG) as the basis of visual task-driven for cooperative task design and task communication. Some constraint transformation rules have been abstracted through the analysis of constraint information, followed which the...
Constraint information is crucial content of CSCD. It becomes more complicated and various with the expanding application and hard to manage. In order to control collaborative design flow efficiently, detect constraint conflicts early and decrease contradiction extension speed, intuitive and vivid constraint information visualization method is created. This paper discusses detailed signification and...
