An AMPL optimization software library for Data Envelopment Analysis

Abstract

This work presents a new optimization software library, which includes a number of Data Envelopment Analysis (DEA) models. All the DEA models have been implemented in the AMPL algebraic modeling language for mathematical programming and solved using either Gurobi Optimizer v5.5 or MINOS v5.51 (for those models having general nonlinear objectives). In order to verify the correctness of the results, real world datasets have been examined and solved using the well-known commercial DEA Solver Pro v8.0c by SAITECH, Inc. We also present a literature review of both commercial and non-commercial DEA software packages and discuss about the benefits and drawbacks of our proposed DEA model library.
