Juan F. Monge, & José L. Ruiz (2023). Setting closer targets based on non-dominated convex combinations of Pareto-efficient units: A bi-level linear programming approach in Data Envelopment Analysis. European Journal of Operational Research, 311, 1084-1096.

Juan F. Monge (Operations Research Center, University Miguel Hernández of Elche) and José L. Ruiz (Operations Research Center, University Miguel Hernández of Elche)
Abstract:
Data Envelopment Analysis (DEA) very often sets unrealistic targets, which require from the decision-making units (DMUs) a huge amount effort, perhaps non-assumable, for their achievement. For the identification of best practices in […]
