20.500.12556/DKUM-97319 Change impact analysis of complex product using an improved three-parameter interval grey relation model Change impact evaluation of complex product plays an important role in controlling change cost and improving change efficiency of engineering change enterprises. In order to improve the accuracy of engineering change impact evaluation, this paper introduces three-parameter interval grey number to evaluate complex products according to the data characteristics. The linear combination of BWM and Gini coefficient method is used to improve the three-parameter interval grey number correlation model. It is applied to the impact evaluation of complex product engineering change. This paper firstly constructs a multi-stage complex network for complex product engineering change. Then the engineering change impact evaluation index system is determined. Finally, a case analysis was carried out with the permanent magnet synchronous centrifugal compressor in a large permanent magnet synchronous centrifugal unit to verify the effectiveness of the proposed method. manufacturing engineering complex product change impact analysis three-parameter interval grey number grey relational model BWM method (best-worst model) Gini weighting method proizvodnja inženirirng kompleksni izdelki analiza vpliva sprememb triparametrski interval siva številka sivi relacijski model metoda BWM (model najboljše-najslabše) Ginijeva metoda uteži true false true Univerza v Mariboru Angleški jezik Slovenski jezik https://apem-journal.org/Archives/2021/Abstract-APEM16-2_185-198.html Članek v reviji 2026-02-27 14:17:37 2026-02-27 14:17:38 2026-02-28 03:16:22 0000-00-00 00:00:00 2021 0 0 str. 185-198 no. 2 Vol. 16 June 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-04-10 2021-06-05 2021-06-25 658.5 269812227 10.14743/apem2021.2.393 1854-6250 APEM16-2_185-198.pdf APEM16-2_185-198.pdf 1 6A13DE6CE350383C97F156E41A7ED638 84cc9249a0d3eb8643bec86aeb330043ed2f4d28844ee70aef913d620358671e 08476994-13df-11f1-bb89-00155d580e1a https://dk.um.si/Dokument.php?lang=slv&id=204028 https://apem-journal.org/Archives/2021/Abstract-APEM16-2_185-198.html 0 0db831c4-13df-11f1-bb89-00155d580e1a https://dk.um.si/Dokument.php?lang=slv&id=204029 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
