Doing so improves the efficiency of analyzing situations to aid in better decision-making. Past methods have mostly been based on expert experience, which may be subjective and inefficient when dealing with large, complex datasets. Recently, the system analysis method has been exploited to find the key data. However, few studies address the indirect effects and heterogeneity of time series data. In this study, a data selection method, the modified Decision-Making Trial and Evaluation Laboratory (DEMATEL) method based on the objective data grey relational analysis (GRA), is used to enhance the ability to analyze time-series data. GRA was first applied to assess the direct impact in the raw data indicators. Then, a modified DEMATEL was adopted to find the overall impact by including the indirect impact and data heterogeneity. We applied the method to analyze the Commercial Modular Aero-Propulsion System Simulation (C-MAPSS) dataset and perform the remaining useful life (RUL) prediction of aircraft engines. The results suggest that our method predicts well. Our work offers a nuanced approach of identifying key information in time series data and has potential applications.<\/jats:p>","DOI":"10.3390\/systems11060267","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T02:00:55Z","timestamp":1684980055000},"page":"267","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Modified DEMATEL Method Based on Objective Data Grey Relational Analysis for Time Series"],"prefix":"10.3390","volume":"11","author":[{"given":"Qun","family":"Wang","sequence":"first","affiliation":[{"name":"School of Economics and Management, Beihang University, Beijing 100191, China"},{"name":"NUS Business School and The Logistics Institute-Asia Pacific, National University of Singapore, Singapore 119613, Singapore"}]},{"given":"Kai","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Beihang University, Beijing 100191, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3620-7658","authenticated-orcid":false,"given":"Mark","family":"Goh","sequence":"additional","affiliation":[{"name":"NUS Business School and The Logistics Institute-Asia Pacific, National University of Singapore, Singapore 119613, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8012-7663","authenticated-orcid":false,"given":"Zeyu","family":"Jiao","sequence":"additional","affiliation":[{"name":"Guangdong Key Laboratory of Modern Control Technology, Institute of Intelligent Manufacturing, Guangdong Academy of Sciences, Guangzhou 510070, China"}]},{"given":"Guozhu","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Beihang University, Beijing 100191, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"60","DOI":"10.1016\/j.eswa.2017.12.026","article-title":"A novel data-driven stock price trend prediction system","volume":"97","author":"Zhang","year":"2018","journal-title":"Expert Syst.
