The theory for measuring efficiency of producers has developed alternative approaches to include the effect of non-discretionary variables in the analysis. A review of different options in the specific literature of Data Envelopment Analysis (DEA) allows us to identify three main approaches: one-stage, two-stage and multi-stage models. Recently, some of(More)
Air Traffic Management (ATM) in general, and Air Traffic Control (ATC) systems, in particular, are commonly limited by their capacity, as they are intended to balance demand in order to provide the best possible performance to the overall network. In the case of ATM, Air Traffic Controllers (ATCO) workload is identified as one of the main limiting factors(More)
Keywords: OR in health services Efficiency Data envelopment analysis Environmental factors Nonparametric analysis a b s t r a c t This paper uses a fully nonparametric approach to estimate efficiency measures for primary care units incorporating the effect of (exogenous) environmental factors. This methodology allows us to account for different types of(More)
This paper uses an innovative approach to evaluate educational performance of Spanish students in PISA 2009. Our purpose is to decompose their overall inefficiency between different components with a special focus on studying the differences between public and state subsidized private schools. We use a technique inspired by the non-parametric free disposal(More)
Traffic Demand Forecast is a key aspect of Air Traffic Management (ATM), even more relevant recently as becomes increasingly more important to effectively scale capacity and associated resources (Air Traffic Controllers amongst them) to match the actual demand. In the case of ATM, many different demand forecasts can be considered, from the simplest to the(More)
OBJECTIVE To evaluate the technical efficiency of primary care units operating in the Basque Health Service during the period 2010-2013, corresponding to the implementation of a care integration strategy by health authorities. METHODS This study included 11 of the 12 primary care units in the Basque Health Service during the period 2010-2013. Data(More)
