This research analyses the environmental footprint of the airline industry in an attempt to highlight potential paths for improvement. We develop a directional economic-environmental distance function (DEED) which accounts for the production of both desirable and undesirable output and the...

We present in this paper the development and application of a cellular automata model that uses irregular cells for simulating land-use change instead of the common regular cells based on the pixels of remote sensing images. The use of irregular cells combines urban form with reliable...

The installation and operation of public facilities, such as schools or hospitals, involve important amounts of public spending, and therefore need to be carefully planned. Research efforts made since the early 1960s led to the development of a rich collection of optimization models and solution...

The deregulation of air transportation was expected to have negative implications on regions with insufficient passenger demand to generate profits – regions where air transportation often plays a crucial role with respect to the mobility of people and goods, as well as to the development of...

In this paper, we present an optimization approach to depot location in one-way carsharing systems where vehicle stock imbalance issues are addressed under three trip selection schemes. The approach is based on mixed-integer programming models whose objective is to maximize the profits of a...

In this article, we introduce an optimization model aimed to assist aviation authorities in their strategic decisions regarding the long-term expansion of a network of airports. The objective is to maximize total system throughput for a given budget taking into account the capacity of the...

Este trabajo estudia la rentabilidad financiera y social de la alta velocidad ferroviaria en España. El análisis se realiza para los cuatro corredores en funcionamiento a finales de 2013. Ambos análisis son contrafactuales, es decir, toman como punto de referencia lo que habría sucedido en...

En este estudio se analiza la regulación aeroportuaria y el sistema de propiedad de los aeropuertos en el mundo, incluyendo diversas opciones de participación privada. En las últimas décadas se ha producido una transición a nivel internacional desde un modelo donde los aeropuertos eran...

In this paper, we assess the potential impacts of different airport charges schemes that can be applied in Madrid Barajas airport. We use a model that has already been applied in the literature to calculate the social welfare of the different price regimes. The term social welfare refers to the...

Air transport provides essential services in modern economies, though it produces significant negative external effects on the environment. Air quality, greenhouse gas emissions and noise are the main issues. The current environmental regulatory practice in air transport usually devises policy...
