Multi-layer Graph Theory Utilisation for Improving Traceability and Knowledge Management in Early Design Stages

Concepts of change propagation analysis in engineering design

“…Change propagation can also involve design parameters, in this context referring to those parameters that are set by the designer. Examples of parameters involved in change propagation are those that define the shape and structure of a product (Zheng et al 2017;Rios-Zapata et al 2017;Zheng et al 2020;Bashir and Ojiako 2020) such as dimensions and material specifications (Koh et al 2012). Parameters in other design domains such as process, labour, cost, material, etc.…”

“…In some cases a decomposition of the design into suitable elements for CPA might already be available, while in other situation a decomposition must be developed from specifically for this purpose (Hamraz et al 2012). Some researchers decompose designs based on systematic processes such as creating patterns or clusters in matrices (Chen et al 2007;Li and Chen 2007, 2010, while some use systematic decomposition methods such as functional decomposition (Raffaeli et al 2007;Rios-Zapata et al 2017;Xue et al 2006;Damak et al 2021), function-structure (Ma et al 2008;Albers et al 2011;Li et al 2017), functionbehaviour-structure (Koh et al 2012), function-parameter (Oizumi and Aoyama 2020) and spatial breakdown by the designer or a team of designers (Yu et al 2017).…”
