Abstract: The paper continues the study on the distinguished property of the space Cp(X)Cp(X) (of real-valued continuous functions over a Tychonoff space XX in the pointwise topology) under the formation of tensor products towards the following […]

Alcaraz, J., Monge, J.F., Ramón, N. (2022) «Ranking ranges in cross-efficiency evaluations: A metaheuristic approach», Journal of the Operational Research Society, 73 (4):779–793

Javier Alcaraz, Juan Francisco Monge and Nuria Ramón (Center of Operations Research (CIO), Miguel Hernández University of Elche) 
Abstract: In the cross-efficiency evaluation, the existence of alternative optima for weights represents an inconvenience because the ranking obtained depends on the weights used. Alcaraz et al. (2013) design an algorithm that provides a range of positions for […]

Javier Alcaraz, Laura Anton-Sanchez, Juan Francisco Monge (Operations Research Center, University Miguel Hernández of Elche)
Abstract: The Kendall rank correlation coefficient, based on the Kendall-τ� distance, is used to measure the ordinal association between two measurements. In this paper, we introduce a new coefficient also based on the Kendall-τ� distance, the Concordance coefficient, and a test to measure whether […]
