Aplicación de técnicas de análisis multicriterio a la localización óptima de extracciones de arenas y gravas en el entorno de zaragoza

Abstract

Land-use decision making is an intrinsic multicriteria problem. In this article we compare different multicriteria methodologies to identify the most appropriate spatial pattern for future sand and gravel extraction in Zaragoza (Spain). A site search analysis is performed using a SAW method and PROMETHEE-2 is used to perform a site selection analysis. Finally, in order to account for uncertainty in the input values we also apply a stochastic approach. The main result is the similarity of the results obtained after applying the different approaches.
