The combination of principal component analysis and grey theory is employed to assign weights to grey indexes. The grey target evaluation model is introduced to evaluate the performance of historical regulation processes, and the evaluation results are analyzed to derive optimization mechanism for pressure regulating schemes.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>A case study based on monitoring data from nearly 300 regulation processes verifies the feasibility of the proposed method. On the one hand, the improved principal component analysis method can achieve rational weighting for grey indexes. On the other hand, the method comparison intuitively shows that the proposed method performs better.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>The pressure test bench is a fundamental technical equipment in the aviation industry, serving the development and testing of aircraft engines. Due to the complex system composition, the pressure and flow adjustment of the test bench heavily rely on manual experience, leading to issues such as slow adjustment speed and insufficient accuracy. This paper proposes a performance evaluation method for the regulation process of pressure test bench, which can draw knowledge from historical regulation processes, provide guidance for the pressure regulation of test benches, and ultimately achieve the goal of reducing equipment operating costs.<\/jats:p><\/jats:sec>","DOI":"10.1108\/gs-01-2024-0013","type":"journal-article","created":{"date-parts":[[2024,8,28]],"date-time":"2024-08-28T08:48:16Z","timestamp":1724834896000},"page":"812-829","source":"Crossref","is-referenced-by-count":0,"title":["A grey target performance evaluation model for aeroengine pressure test bench"],"prefix":"10.1108","volume":"14","author":[{"given":"Yanhua","family":"Zhang","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5707-4480","authenticated-orcid":false,"given":"Kaixin","family":"Ying","sequence":"additional","affiliation":[]},{"given":"Jialin","family":"Zhou","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1985-0198","authenticated-orcid":false,"given":"Yuehua","family":"Cheng","sequence":"additional","affiliation":[]},{"given":"Chenghui","family":"Xu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5732-3319","authenticated-orcid":false,"given":"Zhigeng","family":"Fang","sequence":"additional","affiliation":[]}],"member":"140","published-online":{"date-parts":[[2024,8,29]]},"reference":[{"issue":"3","key":"key2024092402102932500_ref001","doi-asserted-by":"publisher","first-page":"3989","DOI":"10.1038\/s41598-024-53233-7","article-title":"Identification of factors affecting student academic burnout in online education during the COVID-19 pandemic using grey Delphi and grey-DEMATEL techniques","volume":"14","year":"2024","journal-title":"Scientific Reports"},{"issue":"11","key":"key2024092402102932500_ref002","doi-asserted-by":"publisher","first-page":"2991","DOI":"10.12011\/1000-6788-2019-0869-09","article-title":"Research on generalized grey target decision model based on principal component weight of improved regulating variables","volume":"40","year":"2020","journal-title":"System Engineering \u2013 Theory and Practice"},{"key":"key2024092402102932500_ref003","doi-asserted-by":"publisher","DOI":"10.13700\/j.bh.1001-5965.2022.0489","article-title":"Performance evaluation method for attitude control system of Earth observation satellites","volume":"5","year":"2024","journal-title":"Journal of Beijing University of Aeronautics and Astronautics"},{"key":"key2024092402102932500_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/j.dajour.2021.100021","article-title":"TOPSIS and Modified TOPSIS: a comparative analysis","volume":"2","year":"2022","journal-title":"Decision Analytics Journal"},{"key":"key2024092402102932500_ref005","doi-asserted-by":"publisher","first-page":"779","DOI":"10.1109\/ICIBA56860.2023.10164981","article-title":"Effectiveness evaluation of marine law enforcement unmanned aerial vehicle based on ADC model","year":"2023"},{"key":"key2024092402102932500_ref006","doi-asserted-by":"publisher","DOI":"10.1016\/j.cageo.2021.104836","article-title":"Application of group decision-making AHP of confidence index and cloud model for rock slope stability evaluation","volume":"155","year":"2021","journal-title":"Computers and Geosciences"},{"key":"key2024092402102932500_ref007","doi-asserted-by":"publisher","first-page":"228","DOI":"10.1016\/j.comcom.2022.11.005","article-title":"Performance evaluation methodologies for smart grid substation communication networks: a survey","volume":"198","year":"2022","journal-title":"Computer Communications"},{"key":"key2024092402102932500_ref008","doi-asserted-by":"publisher","DOI":"10.1016\/j.commatsci.2022.111820","article-title":"Capabilities of auto-encoders and principal component analysis of the reduction of microstructural images; application on the acceleration of phase-field simulations","volume":"216","year":"2023","journal-title":"Computational Materials Science"},{"issue":"4","key":"key2024092402102932500_ref009","doi-asserted-by":"publisher","first-page":"3125","DOI":"10.15244\/pjoes\/162250","article-title":"Virtual power plant operation based on entropy-weight-improved cloud risk assessment model","volume":"32","year":"2023","journal-title":"Polish Journal of Environmental Studies"},{"issue":"2065","key":"key2024092402102932500_ref010","doi-asserted-by":"publisher","first-page":"20150202","DOI":"10.1098\/rsta.2015.0202","article-title":"Principal component analysis: a review and recent developments","volume":"374","year":"2016","journal-title":"Philosophical Transactions.
