INCIDENCIA DE LA INCLUSIÓN DE LOS FACTORES SOCIALES Y AMBIENTALES EN LA TOMA DE DECISIÓN MEDIANTE MÉTODOS MULTICRITERIO

Abstract

Technical and economic factors have to date been the principal points to take into account in decision making in engineering projects. It has become increasingly patent that social and environmental criteria need to be tackled within these problems. Thus we can see how the social acceptance regarding a company policy or the environmental benefits of one or other production alternative, are factors that have an increasingly greater weight in these decisions. It is for that reason that we present the case of the election of a disinfection system for treated waste water for agricultural use. In this case, water quality, costs, social and environmental criteria have been considered. We have been able to observe, by means of a sensitivity analysis, how the final decision changes depending on the weight given to these factors. For each of the experts consulted the inclusion of these factors leads to certain alternatives being prioritized over others, a situation which did not occur when only quality and cost factors were considered. Keywords: group decision; social criteria; environmental criteria; aid decision support
