  1. Available online at www.ijo.ir Iranian Journal of Optimization 3(2011) 183- 196 Iranian Journal of Optimization A Linear Programming Approach for Setting Integer-Valued Targets in DEA Reza Kazemi Matin* Department of Mathematics, Islamic Azad University, Karaj Branch, P.O. Box 31485-313 Karaj, Iran. Abstract Data envelopment analysis (DEA) is a non-parametric technique to measure the relative efficiency of a set of firms called decision making units (DMUs). This paper discusses several previous DEA techniques in efficiency evaluation and setting integer targets for integer-valued units and suggests a new improvement on the ability of linear data envelopment analysis models for finding efficient DMUs, benchmarking inefficient DMUs in integer-valued DEA (IDEA). An empirical study is also used to illustration the method. Keyword: Data envelopment analysis (DEA), Integer-value targets, Mixed integer linear programming (MILP), Linear programming (LP). * Corresponding author: E-Mail :rkmatin@kiau.ac.ir
