In the first stage, prospective inputs and outputs are determined by field studies. The second stage employs IT2F-AHP to identify the most appropriate performance indicators based on vague expert judgements. Finally, DEA is applied to the decision-making units (DMUs) based on the selected set of input and output measures. The proposed methodology proves its merit on a case study addressing the performance of real estate investment trusts (REITs) in Turkey during their 10-year journey of trading on Borsa Istanbul (BIST). The results demonstrate that the average scores for technical, pure technical and scale efficiencies are 66%, 80% and 80%, respectively. Considering the technical efficiency scores, Turkish REITs could have reduced their input factors by an average of 34%. The findings also reveal that the majority of Turkish REITs suffer from economies of scale and could have improved their performance by expansion.<\/jats:p>","DOI":"10.1142\/s0219622019500354","type":"journal-article","created":{"date-parts":[[2019,10,30]],"date-time":"2019-10-30T03:38:20Z","timestamp":1572406700000},"page":"1785-1820","source":"Crossref","is-referenced-by-count":19,"title":["Performance Evaluation of Real Estate Investment Trusts using a Hybridized Interval Type-2 Fuzzy AHP-DEA Approach: The Case of Borsa Istanbul"],"prefix":"10.1142","volume":"18","author":[{"given":"Mustafa Kemal","family":"Yilmaz","sequence":"first","affiliation":[{"name":"Ibn Haldun University, School of Business, Ulubatli Hasan Cad., No: 2 Basaksehir, 34494, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali Osman","family":"Kusakci","sequence":"additional","affiliation":[{"name":"Ibn Haldun University, School of Business, Ulubatli Hasan Cad., No: 2 Basaksehir, 34494, Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ekrem","family":"Tatoglu","sequence":"additional","affiliation":[{"name":"Ibn Haldun University, School of Business, Ulubatli Hasan Cad., No: 2 Basaksehir, 34494, Istanbul, Turkey"},{"name":"University of Sharjah, College of Business Administration, P.O.
