Abstract
Changes are unavoidable during the product evolution process, and the propagation of changes leads to an augmentation of the design complexity. The acquisition of an optimal change solution provides a significant challenge for designers due to the non-uniqueness of change propagation paths. This paper aims to develop a method to search for change propagation paths. A product model from the parameter linkage perspective is constructed, through which the propagation mechanism of changes is analyzed. Then, a searching method is proposed based on the product model and change propagation mechanism. It is found that the parameter linkages in designs can be organized in a structured manner with two types of parameter linkages, and the change propagation is an alternate process of influence diffusion and change routing. A case study presented in this paper indicates that this method can provide support for the searching and optimal selection of change propagation paths.
