摘要： Variant product design is critical to the continued survival of a product in the demand-changing market. As variant product design involves numerous and concurrent attempts at requirement and product modification, a change impact analysis (CIA) becomes essential in order to capture both the potential and contextual impacts of a change proposal, and thereby ensure the consistency of the product’s integrated content throughout the process of carrying out any changes. In this regard, this paper presents an attribute-based, object-oriented approach for effectively and comprehensively performing the CIA tasks in variant product design. This approach models the integrated content of a product by characterizing its components and associated requirements with attributes and linkages. It then features an object-oriented change propagation design in order to handle the dynamic and recursive CIA loops. This approach is also able to show the collective impact when multiple changes are attempted. A computerized prototype, EPCII_EC, is implemented in order to realize the approach, and an illustrative product case with a comparative evaluation is provided in order to validate the work. Issues and limitations of this study are also discussed and suggestions are provided for future studies. •An integrated product model for identifying contextual impacts of design changes.•An OO mechanism for handling dynamic and recursive change propagation processes.•A tool to handle multiple change attempts and show the collective impact result. 出版者： Elsevier Ltd 出版日期： 2015-05-01 出處： Computer aided design, 2015-05, Vol.62, p.203-217 資源來源： Elsevier ScienceDirect Journals AutoHoldings 版權： 2014 Elsevier Ltd 識別號： ISSN: 0010-4485 識別號： EISSN: 1879-2685 識別號： DOI: 10.1016/j.cad.2014.11.006
