Zubcoff, J.-J., Olcina, J., Morales, J., Mazón, J.-N., Mayoral, A.M. (2023) "Usefulness of open data to determine the incidence of COVID-19 and its relationship with atmospheric variables in Spain during the 2020 lockdown", Technological Forecasting and Social Change, 186:122108

Jose-Jacobo Zubcoff, Jorge Olcina, Jose-Norberto Mazón (University of Alicante), Javier Morales and Asunción M. Mayoral (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: The SARS-CoV-2 pandemic and the spread of the COVID-19 disease led to a lockdown being imposed in Spain to minimise contagion from 16 March 2020 to 1 May 2020. Over this period, […]

Miriam Esteva, Juan Aparicio, Jesús Javier (Operations Research Center, University Miguel Hernández of Elche) and Joe Zhu (Foisie Business School, Worcester Polytechnic Institute,)
Abstract: In the technical efficiency evaluation area, it may happen that many observations obtain a similar relative technical efficiency status, making it difficult to discriminate between them. The determination of super-efficiency has been […]

Borrás, F., Ruiz, J.L., Sirvent, I. (2023) "Peer evaluation through cross-efficiency based on reference sets", Omega, 114:102739

Fernando Borrás (Departamento de Estadística, Matemáticas e Informática, Universidad Miguel Hernández), José Luis Ruiz and Inmaculada Sirvent (Operations Research Center, University Miguel Hernández of Elche)
Abstract: Cross-efficiency evaluates the performance of decision making units (DMUs) from the perspective of all of the others, through their individual Data Envelopment Analysis (DEA) weights. The main weakness with this […]
