The lack of the ability to generate the actual weights, not considering the impact of undesirable outputs in the evaluation process and the measuring of efficiencies of DMUs based upon precise observations are three main drawbacks of the conventional DEA models. This paper proposes a novel approach for finding the common set of weights (CSW) to compute efficiencies in DEA model with undesirable outputs when the data are represented by fuzzy numbers. The proposed approach is based on fuzzy arithmetic which formulates the fuzzy additive DEA model as a linear programing problem and gives fuzzy efficiencies of all DMUs based on resulting CSW. We demonstrate the applicability of the proposed model with a simple numerical example. Finally, in the context of performance management, an application of banking industry in Iran is presented for analyzing the influence of fuzzy data and depicting the impact of undesirable outputs over the efficiency results.<\/jats:p>","DOI":"10.3233\/jifs-201022","type":"journal-article","created":{"date-parts":[[2020,10,16]],"date-time":"2020-10-16T12:12:46Z","timestamp":1602850366000},"page":"7705-7722","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["A common-weights approach for efficiency evaluation in fuzzy data envelopment analysis with undesirable outputs: Application in banking industry"],"prefix":"10.1177","volume":"39","author":[{"given":"Mohammad","family":"Kachouei","sequence":"first","affiliation":[{"name":"Department of Mathematics, Yadegar-e-Imam Khomeini (RAH) Shahre Rey Branch, Islamic Azad University, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Ebrahimnejad","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Qaemshahr Branch, Islamic Azad University, Qaemshahr, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hadi","family":"Bagherzadeh-Valami","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Yadegar-e-Imam Khomeini (RAH) Shahre Rey Branch, Islamic Azad University, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,10,14]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trd.2015.12.016"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2016.04.006"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40815-020-00821-0"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00500-018-3504-3"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3233\/IFS-151710"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","unstructured":"BagheriM.
