In pursuit of business optimization, cost reduction, improved reliability, and enhanced market competitiveness, selecting the most suitable cloud platform has become a major practical challenge. This paper proposes a novel two-stage multi-attribute decision-making (MADM) model, enhanced through the use of interval type-2 fuzzy sets (IT2FMADM). This was demonstrated through a case study in an IT company based in Serbia. In the first stage, three experts from the company were surveyed to assess the relative importance of the attributes, and their evaluations were aggregated using the fuzzy harmonic mean operator. As a result, unified fuzzy weight vectors were obtained. In the second stage, two MADM methods extended with interval type-2 fuzzy sets, namely COmplex PRoportional Assessment (IT2FCOPRAS) and Evaluation based on Distance from Average Solution (IT2FEDAS), were applied to support the selection of the most suitable cloud platform. Each platform was evaluated by decision-makers (DMs), who reached a consensus in their assessments, supported by data from company records. A comparative analysis of the results revealed that different methods may produce varying rankings of alternatives, particularly when the alternatives are objectively similar in their characteristics. Nevertheless, the proposed model can serve as a highly useful decision-support tool for company management.<\/jats:p>","DOI":"10.3390\/axioms14060469","type":"journal-article","created":{"date-parts":[[2025,6,16]],"date-time":"2025-06-16T10:47:22Z","timestamp":1750070842000},"page":"469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cloud Platform Selection Using Extended Multi-Attribute Decision-Making Methods with Interval Type-2 Fuzzy Sets"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-0208-7663","authenticated-orcid":false,"given":"Ivana","family":"Spaseni\u0107","sequence":"first","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, Sestre Janji\u0107 6, 34000 Kragujevac, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2236-967X","authenticated-orcid":false,"given":"Danijela","family":"Tadi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, Sestre Janji\u0107 6, 34000 Kragujevac, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2094-9649","authenticated-orcid":false,"given":"Milan","family":"\u010cabarkapa","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, Sestre Janji\u0107 6, 34000 Kragujevac, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3583-9434","authenticated-orcid":false,"given":"Dragan","family":"Marinkovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering and Transport Systems, TU Berlin, 10623 Berlin, Germany"},{"name":"Mechanical Science Institute, Vilnius Gediminas Technical University-VILNIUS TECH, Plytin\u0117s st. 25, LT-10105 Vilnius, Lithuania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6964-5673","authenticated-orcid":false,"given":"Nikola","family":"Komatina","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, Sestre Janji\u0107 6, 34000 Kragujevac, Serbia"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,16]]},"reference":[{"key":"ref_1","first-page":"98","article-title":"Understanding the Effect of Cloud Computing on Organizational Agility: An Empirical Examination","volume":"43","author":"Liu","year":"2018","journal-title":"Int.
