Basically, the traditional DEA scheme calculates the best relative efficiency score (i.e., the \u201coptimistic\u201d efficiency) of each DMU with the most favorable weights. A decision maker may be unable to compare and fully rank the efficiencies of different DMUs that are calculated using these potentially distinct sets of weights on the same basis. Based on the literature, the assignable worst relative efficiency score (i.e., the \u201cpessimistic\u201d efficiency) for each DMU can also be determined. In this paper, the best and the worst relative efficiencies are considered simultaneously. To measure the overall performance of the DMUs, an integration of both the best and the worst relative efficiencies is considered in the form of an interval. The advantage of this efficiency interval is that it provides all of the possible efficiency values and an expanded overview to the decision maker. The proposed method determines the lower- and upper-bounds of the interval efficiency over a common set of weights. To demonstrate the implementation of the introduced method, a numerical example is provided.<\/jats:p>","DOI":"10.1155\/2014\/346763","type":"journal-article","created":{"date-parts":[[2014,6,1]],"date-time":"2014-06-01T17:04:44Z","timestamp":1401642284000},"page":"1-9","source":"Crossref","is-referenced-by-count":6,"title":["Ranking DMUs by Calculating the Interval Efficiency with a Common Set of Weights in DEA"],"prefix":"10.1155","volume":"2014","author":[{"given":"Vahideh","family":"Rezaie","sequence":"first","affiliation":[{"name":"Department of Mathematical Sciences, Faculty of Science and Ibnu Sina Institute, Nanotechnology Research Alliance, Universiti Teknologi Malaysia, Skudai, 81310 Johor Bahru, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tahir","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Department of Mathematical Sciences, Faculty of Science and Ibnu Sina Institute, Nanotechnology Research Alliance, Universiti Teknologi Malaysia, Skudai, 81310 Johor Bahru, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siti-Rahmah","family":"Awang","sequence":"additional","affiliation":[{"name":"Faculty of Management, Universiti Teknologi Malaysia, Skudai, 81310 Johor Bahru, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masumeh","family":"Khanmohammadi","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Faculty of Science, Islamic Azad University, Islamshahr Branch, Tehran 11369, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Normah","family":"Maan","sequence":"additional","affiliation":[{"name":"Department of Mathematical Sciences, Faculty of Science and Ibnu Sina Institute, Nanotechnology Research Alliance, Universiti Teknologi Malaysia, Skudai, 81310 Johor Bahru, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/0377-2217(78)90138-8"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(01)00055-8"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.amc.2005.04.023"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.cam.2005.12.025"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.apm.2010.05.019"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.apm.2010.11.055"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(99)00319-7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2011.01.004"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/492421"},{"year":"1992","key":"10"},{"issue":"1","key":"11","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1080\/07408179108963835","volume":"23","year":"1991","journal-title":"IIE Transactions"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/0305-0483(93)90042-J"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(97)00313-5"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2010.04.011"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.39.10.1261"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/0377-2217(92)90148-3"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2006.06.012"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/S0305-0548(03)00072-8"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1002\/nav.3800090303"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.cor.2006.09.006"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1007\/s10614-014-9423-1"}],"container-title":["Journal of Applied Mathematics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/346763.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/346763.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/346763.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T10:09:47Z","timestamp":1498126187000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jam\/2014\/346763\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":21,"alternative-id":["346763","346763"],"URL":"https:\/\/doi.org\/10.1155\/2014\/346763","relation":{},"ISSN":["1110-757X","1687-0042"],"issn-type":[{"type":"print","value":"1110-757X"},{"type":"electronic","value":"1687-0042"}],"subject":[],"published":{"date-parts":[[2014]]}}}
