However, all prior studies, except a few of them, assume that changes are equi-proportional. This simplifying assumption makes scale elasticity measure to preserve the throughput mix and implicitly ignores both input independencies and decision-maker preferences. This paper seeks to investigate two main objectives. It initially proposes the notion of directional scale elasticity to allow evaluation of elasticity in any direction which may naturally alter the mix. Subsequently, by providing a tangible geometric interpretation, it attempts to clarify the measure. Relevant computations are used to construct cross sections of frontier in a given direction by enlisting the advantages of parametric optimization algorithm. <\/jats:p>","DOI":"10.1142\/s0217595916500263","type":"journal-article","created":{"date-parts":[[2016,7,18]],"date-time":"2016-07-18T09:37:43Z","timestamp":1468834663000},"page":"1650026","source":"Crossref","is-referenced-by-count":3,"title":["On the Calculation of Directional Scale Elasticity in Data Envelopment Analysis"],"prefix":"10.1142","volume":"33","author":[{"given":"Mahdi","family":"Mirjaberi","sequence":"first","affiliation":[{"name":"Department of Mathematics, Karaj Branch, Islamic Azad University, Karaj, Iran"}]},{"given":"Reza","family":"Kazemi Matin","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Karaj Branch, Islamic Azad University, Karaj, Iran"}]}],"member":"219","published-online":{"date-parts":[[2016,8,5]]},"reference":[{"key":"S0217595916500263BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/j.omega.2004.11.002"},{"key":"S0217595916500263BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2012.01.034"},{"key":"S0217595916500263BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/s11123-014-0399-6"},{"key":"S0217595916500263BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/0377-2217(92)90178-C"},{"key":"S0217595916500263BIB005","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.30.9.1078"},{"key":"S0217595916500263BIB006","volume-title":"New directions: Efficiency and productivity","author":"F\u00e4re R","year":"2003"},{"key":"S0217595916500263BIB007","doi-asserted-by":"publisher","DOI":"10.1007\/BF00157045"},{"key":"S0217595916500263BIB008","doi-asserted-by":"publisher","DOI":"10.1057\/palgrave.jors.2601741"},{"key":"S0217595916500263BIB009","doi-asserted-by":"publisher","DOI":"10.1007\/s11123-007-0047-5"},{"key":"S0217595916500263BIB010","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(99)00200-3"},{"key":"S0217595916500263BIB011","doi-asserted-by":"publisher","DOI":"10.1016\/S0377-2217(01)00389-7"},{"key":"S0217595916500263BIB012","doi-asserted-by":"publisher","DOI":"10.1057\/palgrave.jors.2601759"},{"key":"S0217595916500263BIB013","doi-asserted-by":"publisher","DOI":"10.1007\/s10598-007-0036-6"},{"issue":"6","key":"S0217595916500263BIB014","first-page":"1743","volume":"58","author":"Podinovski VV","year":"2010","journal-title":"Informs"},{"key":"S0217595916500263BIB015","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2008.06.015"},{"key":"S0217595916500263BIB016","doi-asserted-by":"publisher","DOI":"10.1515\/9781400873173"},{"key":"S0217595916500263BIB017","volume-title":"Theory of Cost and Production Functions","author":"Shepard RW","year":"1970"},{"key":"S0217595916500263BIB018","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2006.11.042"},{"key":"S0217595916500263BIB019","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2013.01.012"}],"container-title":["Asia-Pacific Journal of Operational Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0217595916500263","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T18:23:45Z","timestamp":1565115825000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0217595916500263"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,8]]},"references-count":19,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2016,8,5]]},"published-print":{"date-parts":[[2016,8]]}},"alternative-id":["10.1142\/S0217595916500263"],"URL":"https:\/\/doi.org\/10.1142\/s0217595916500263","relation":{},"ISSN":["0217-5959","1793-7019"],"issn-type":[{"value":"0217-5959","type":"print"},{"value":"1793-7019","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,8]]}}}
