Public ISBD [article]  inJournal of the operational research society (JORS) > Vol. 61 N° 8 (Août 2010) . - pp. 1297–1301 Titre : Linear programming solutions and distance functions under α-returns to scale Type de document : texte imprimé Auteurs : J.-P. Boussemart, Auteur ; W. Briec, Auteur ; H. Leleu, Auteur Année de publication : 2011 Article en page(s) : pp. 1297–1301 Note générale : Recherche opérationnelle Langues : Anglais (eng) Mots-clés : Data envelopment analysis Methodology Production Index. décimale : 001.424 Résumé : This note generalizes analytical relationships among activity variables of Data envelopment analysis models previously derived in a previous article by the authors of this note. We relax the assumption of constant returns to scale by showing that the key results hold under a weaker assumption of homogeneity. We use the notion of α-returns to scale to extend the analysis to strictly increasing and decreasing returns, covering now the whole range of returns to scale for multi-output homogenous technologies.
