fa عمومى General پژوهشي Research <p>To rank Decision Making Units (DMU) in Data Envelopment Analysis (DEA), the peer-evaluation based cross-efficiency method is generally used. Indeed, in this method, each DMU is evaluated from the view point of other DMUs. In this article, a method is suggested which instead examines each DMU just by using the weights resulting from the evaluation of ideal and anti-ideal virtual DMUs and thus exhibits a new secondary goal that possibly prevents the existence of multiple weights in cross-efficiency evaluation, in addition to introducing a new cross-efficiency score. The advantage of this method over the others is that it needs less computations in determining the cross-efficiency score. To this end, some examples are illustrated which show how it differs with other methods.</p> <p></p> 69 79 http://ijorlu.lahijan.iau.ir/browse.php?a_code=A-10-12-1&slc_lang=fa&sid=1 S.H. naseri nasseri@umz.ac.ir 1003194753284600721 1003194753284600721 Yes Departement of Mathematics, University of Mazandaran, Babolsar, Iran H.
