1. Inverse DEA Model with Fuzzy Data for Output Estimation

A. Mahmoodi Rad; R. Dehghan; F. Hosseinzadeh Lotfi

Volume 4, Issue 2 , Summer 2012, , Pages 336-353

Abstract
  In this paper, we show that inverse Data Envelopment Analysis (DEA) models can be used to estimate output with fuzzy data for a Decision Making Unit (DMU) when some or all inputs are increased and deficiency level of the unit remains unchanged.  Read More

2. The interval Malmquist productivity index in DEA

F. Rezai Balf; F. Hosseinzadeh Lotfi; M. Alizadeh Afrouzi

Volume 4, Issue 1 , Winter 2012, , Pages 272-281

Abstract
  One of the most popular approaches to measuring productivity changes is based on using Malmquist productivity indexes. In this paper we propose a method for obtaining interval Malmquist productivity index (IMPI). The classical DEA models have been before used for measuring the Malmquist ...  Read More
