“…Regarding design change and change propagation, there have been some existing researches, for example, Clarkson et al. 21 proposed a change propagation prediction method for complex design; Eckert et al. 22 studied the characteristics of change propagation, and categorized the change propagation into blossom propagation, ripple propagation, and avalanche propagation; Raffaeli et al.…”

Excellence in function and performance is one of the key reasons for a product to sustain its market competitiveness. Upgrading of products, including those of the adaptable-function products, is necessary to ensure their market attractiveness. Current research that is specifically on upgrading of adaptable-function products is lacking. To this end, this paper attempts to study both functional aspect and performance aspect of upgrade design of this kind of products. For the former, the study focuses on some fundamental issues of functional upgrading relevant to the upgrading type, where an analogy-based functional upgrading strategy is proposed. The proposed work is illustrated by the functional upgrading of an electric drill design case. For the latter, the study focuses on how to evaluate the upgrading priority, for which a number of performance attributes to be upgraded are specified. For this purpose, the technology potentials for enabling the upgrade design (which should be maximized) and the influence caused by the upgrading (which should be minimized) are first studied. Based on technology potentials and upgrading influence, the priority ranking is evaluated to help the designer making performance upgrading decisions. Finally, a case study of upgrading a multifunction machine tool is presented, which demonstrates the feasibility of the proposed evaluation method. With the help of the established upgrading design prototype and the strategy of upgrading priority ranking guidelines, the designers can get the relevant design support during their upgrade design process.

In the product-oriented approaches usually, dependencies between components are captured by likelihood and impact, 3 attributes, 13 design parameters, 14 and topology (contact surface) 15 to explore the effect of change requirements. Moreover, extensions were made to wider the scope of these approaches and also to refine the results.…”

Design projects have been surrounded by tight schedule and cost overruns. Therefore, it is indispensable to resolve the design changes in an economical way. This work introduces an advanced technique to assess and optimize change propagation paths for multiple change requirements occurring simultaneously during the product development process. A novel multiple change requirement algorithm and a mathematical model considering the overall propagated risk are developed, to explore cost-effective change propagation paths in terms of lead time. The risk is quantified with regard to propagation likelihood and change impact, which results in re-work. Design structure matrix framework is used to capture the dependencies between components. It is revealed that the change requirements execution sequence has a significant effect on the total number of change propagation paths, change steps, distinct change components, and completion time. This approach is illustrated by a case study, which indicates that the proposed methodology can assist the designer in exploring and selecting optimal change propagation paths.

“…Clarkson built DSM according to the parameter relationships of design components. 15 A further extension is studied by Hamraz et al, 16 who modified DSM to exclude the propagation loop path and self-dependent path. Morkos et al 17 added a requirement layer in DSM to control the requirement change propagation.…”

Lack of objective design change analysis model is a major problem for the accurate change impact prediction. To solve this problem, this paper proposes an ontology-based model named design change analysis model to organize the unstructured design properties as a basis for design change management. Design change analysis model is constructed by formalizing the mechanical design specifications in the form of design property network. Benefiting from the fine-grained organization, design change analysis model ensures the objectivity and accuracy of design change impact assessment. Since design change analysis model satisfies the attributions of small-world network, the change impact assessment should focus on more meaningful aspects including the linkage weight, node degree, and long-chain linkages of design change analysis model. With design change analysis model, the changeability of each design property which provides a quantified change propagation measurement could be evaluated. Additionally, different components could be distinguished in design change analysis model by using clustering algorithms without specializing them in advance. Design change analysis model modeled in web ontology language is a semantic enrichment model. It supports the semantic design change management due to the mathematic logic-based semantics of web ontology language and semantic web rule language. These lays a basis for updating changes among heterogeneous product development systems, and acquiring feasible change impacted properties.
