Data envelopment analysis 2018/04/21 Data envelopment analysis (DEA) is a nonparametric method in operations research and economics for the estimation of production frontiers[clarification needed]. It is used to empirically measure productive efficiency of decision making units (or DMUs). DEA Software 2018/04/21 What is the best software for Data Envelopment Analysis (DEA)? DEA SOFTWARE TOOLS AND TECHNOLOGY 2018/04/21 Today’s DEA practitioners and researchers have a wide range of solution technology choices. Clearly, software is no longer an impediment to the incorporation of DEA into decision-support systems and benchmarking processes. This is evidenced by the availability of interoperable tools with a variety of user interfaces, advanced modeling options, and the power to evaluate large-scale data sets on inexpensive computing platforms. This survey describes and critiques prominent DEA software packages, both commercial and non-commercial, and summarizes the current state of the art.
