Parameter coordination for multidisciplinary collaborative design

This paper presents a parameter coordination approach based on constraints network to support multidisciplinary collaborative design. Firstly, from the point of view of collaborative design, the model of constraints network for parameter coordination is studied. In this model, interval boxes are adopted to describe the uncertainty of design parameters quantitatively to support multidisciplinary collaborative and enhance the design robustness. Secondly, a general consistency algorithm is designed to predict conflict and refine the intervals for parameter coordination, which verso the design process early in the process and assist the designers in determining design variables to reduce the multidisciplinary iterations in collaborative design. Finally, the method is demonstrated by a bogie parameter design problem.
