Abstract
In this paper, we describe an interactive web application (deaR-shiny) to measure efficiency and productivity using data envelopment analysis (DEA). deaR-shiny aims to fill the gap that currently exists in the availability of online DEA software offering practitioners and researchers free access to a very wide variety of DEA models (both conventional and fuzzy models). We illustrate how to use the web app by replicating the main results obtained by Carlucci, Cirà and Coccorese in 2018, who investigate the efficiency and economic sustainability of Italian regional airport by using two conventional DEA models, and the results given by Kao and Liu in their papers published in 2000 and 2003, who calculate the efficiency scores of university libraries in Taiwan by using a fuzzy DEA model because they treat missing data as fuzzy numbers.
Highlights
Daraio, Kerstens and Cavalcante [51] conducted a comprehensive review of current software options for productivity and efficiency analysis and carried out a comparative analysis on them
It is worth noting the great diversity of models implemented in MaxDEA (http://www.maxdea.cn), which is developed with VBA Access
The relative efficiency scores of the university libraries in Kao and Liu [77,78] are obtained by running an output-oriented fuzzy data envelopment analysis (DEA) model under variable returns to scale
Summary
In parallel to the development of DEA models, some software has emerged to facilitate their use by practitioners. Daraio, Kerstens and Cavalcante [51] conducted a comprehensive review of current software options for productivity and efficiency analysis and carried out a comparative analysis on them It is worth noting the great diversity of models implemented in MaxDEA (http://www.maxdea.cn (accessed on 12 June 2021)), which is developed with VBA Access. MaxDEA offers two versions to users: (1) MaxDEA Basic, which allows running basic models (CCR, BCC, Slacks Based Model and Cost model) under different orientations (input, output and non-orientation) and returns-to-scale with no limit of DMUs, and (2) MaxDEA Ultra, the commercial version in which a wide variety of models are available (a list of them can be consulted at: http://maxdea.com/Features.htm (accessed on 12 June 2021)). DeaR-shiny aims to fill the gap that currently exists in the availability of online DEA software and it offers practitioners free access to a wide variety of DEA models and without any requirement of prior registration. Detailed technical information about the DEA models and built-in datasets available in deaR-shiny can be consulted at: https://rdrr.io/cran/deaR/man/ (accessed on 12 June 2021)
