PilarMartínez Núñez, MargaritaMultivariate data envelopment analysis to measure airline efficiency in european airspace: a network-based approachART-2019-115691In this paper, data envelopment analysis (DEA) is applied to exhaustively examine the efficiency of the main airline companies in the European airspace by using novel input/output parameters: business management factors, network analysis metrics, as well as social media estimators. Furthermore, we also use network analysis to provide a better differentiation among efficiency values. Results indicate that user engagement, as well as the analysis of the position within the airspace-from an operative perspective, influence the efficiency of the airline companies, allowing a more comprehensive understanding of its functioning.2019http://zaguan.unizar.es/record/8756410.3390/app9245312http://zaguan.unizar.es/record/87564oai:zaguan.unizar.es:87564info:eu-repo/grantAgreement/ES/AEI-FEDER/TIN2016-78011-C4-3-Rinfo:eu-repo/grantAgreement/ES/DGA/S42-17R-CREVALORApplied Sciences (Switzerland) 9, 24 (2019), 5312 [23 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
