Ruiz, J.L., Sirvent, I., (2022) "Identifying suitable benchmarks in the way toward achieving targets using data envelopment analysis", International Transactions in Operational Research, 29 (3):1749–1768

José Luis Ruiz and Inmaculada Sirvent (Operations Research Center, University Miguel Hernández of Elche)
Abstract: Setting the closest targets is an appropriate approach for planning. Closest targets minimize the gap between actual performances and best practices, so they are the ones that require the least effort from organizations for their achievement. However, this paper shows that, […]

Ruiz, J.L., Sirvent, I. (2022) «Benchmarking within a DEA framework: setting the closest targets and identifying peer groups with the most similar performances», International Transactions in Operational Research, 29 (1): 554–573

José Luis Ruiz and Inmaculada Sirvent (Operations Research Center, University Miguel Hernández of Elche)
Abstract: Data envelopment analysis (DEA) is widely used as a benchmarking tool for improving performance of organizations. For that purpose, DEA analyses provide information on both target setting and peer identification. However, the identification of peers is actually a by-product of DEA. […]
