- Selección de criterios sociales y ambientales para la delimitación de núcleos rurales en Galicia, EspañaPublication . Barbosa-Brandão, Vasco; Pérez-Rodríguez, Fernando; Rojo-Alboreca, Alberto; Ferreira-Neto, José AmbrósioRural settlements (RS) are references of the territorial reality of the town settlement and constitute a set of social and cultural constructions. Its delimitation is one of the most important and complicated tasks within territorial planning. This paper presents a comparison of methodologies to select the most important criteria for the delimitation of the rural settlements in Galicia (northwest of Spain), considering social, environmental and landscaping aspects. Due to the subjective nature of many of the criteria involved, an expert judgment was designed involving 12 decision-makers, experts from different disciplines related to rural planning, who evaluated the weight or importance of a scheme of 108 criteria spread over three levels, through two methodologies: the scoring method and the multicriteria decision making methodology analytical hierarchy process (AHP). The results indicated that the AHP method was the best methodology for obtaining weights in these criteria compared to the scoring method. The built structure criterion was the only one that had the best result according to the scoring method. The research allows concluding that in both methodologies social criteria obtained better weights than environmental and landscape criteria.
- Selection of social and environmental criteria for the delimitation of rural settlements in Galicia, SpainPublication . Barbosa-Brandão, Vasco; Pérez-Rodríguez, Fernando; Rojo-Alboreca, Alberto; Ferreira-Neto, José AmbrósioLos núcleos rurales (NR) son una referencia de la realidad territorial del asentamiento de un pueblo y constituyen un conjunto de construcciones sociales y culturales. Su delimitación es una de las tareas más importantes y complicadas dentro de la planificación territorial. Este trabajo presenta una comparación de metodologías para seleccionar los criterios más importantes para la delimitación de los núcleos rurales de Galicia (noroeste de España), considerando conjuntamente aspectos sociales, ambientales y paisajísticos. Debido al carácter subjetivo de muchos de los criterios implicados, se diseñó un juicio de expertos en el que participaron 12 decisores, expertos de diferentes disciplinas relacionadas con el medio rural, que evaluaron el peso o importancia de un esquema de 108 criterios repartidos en tres niveles, mediante dos metodologías: el método de puntuación (o scoring) y la metodología de toma de decisiones multicriterio analytical hierarchy process (AHP). Los resultados indicaron que el método AHP fue mejor metodología para la obtención de pesos en dichos criterios que el método de puntuación. El criterio estructura edificada fue el único que tuvo mejor resultado según el método de puntuación. La investigación permitió concluir que en ambas metodologías los criterios sociales obtuvieron mejores pesos que los criterios ambientales y paisajísticos.
- The triangle assessment method: a new procedure for eliciting expert judgementPublication . Pérez-Rodríguez, Fernando; Rojo-Alboreca, AlbertoThe Analytic Hierarchy Process (AHP) is one of the most widely used Multi-Criteria Decision-Making methods worldwide. As such, it is subject to criticisms that highlight some potential weaknesses. In this study, we present a new Multi-Criteria Decision-Making method denominated the “Triangular Assessment Method” (referred to by its Spanish abbreviation, MTC©). The MTC© aims to make use of the potential of AHP while avoiding some of its drawbacks. The main characteristics and advantages of the MTC© can be summarised as follows: (i) evaluation of criteria, and of the alternative options for each criterion, in trios instead of pairs; (ii) elimination of discrete scales and values involved in judgements; (iii) a substantial reduction in the number of evaluations (trios) relative to the corresponding number of pairs which would have to be considered when applying the AHP method; (iv) consistent decision-making; (v) introduction of closed cyclical series for comparing criteria and alternatives; and (vi) the introduction of opinion vectors and opinion surfaces. This new method is recommended for supporting decision-making with large numbers of subjective criteria and/or alternatives and also for group decisions where the consensus must be evaluated. The MTC© provides a different promising perspective in decision-making and could lead to new research lines in the field of information systems.
