Modelo para la toma de decisiones multricriterio en grupo para la reducción del riesgo por movimientos en masa en el provincia del Azuay : Propuesta de un modelo de toma de decisiones multicriterio en grupo para la reducción del riesgo por movimientos en masa en la provincia del Azuay

Abstract

The objective of this work is to strengthen the National Risk Management System of Ecuador through the development of a group decision-making model. This model is intended for the prevention, mitigation and monitoring of mass movements, based on the susceptibility of the territory obtained through quantitative techniques. The study focuses on the province of Azuay, located in the southern region of the Ecuadorian Sierra and crossed by the Andes mountain range. This area has a high susceptibility to mass movements due to a combination of socioeconomic factors and specific geological, geomorphological, hydrological and climatic conditions; which is why the management of the risk of mass movements becomes complex, making the decision processes involve multidimensional elements, diverse objectives, multiple intervention alternatives and inherent uncertainty. In this context, the construction of the group decision-making model (TDMCG) is based on the susceptibility of the territory and uses multicriteria analysis techniques, such as Fuzzy-TOPSIS. Furthermore, this model is aligned with the Science, Technology and Innovation (PCTI) policies, ensuring its coherence with national objectives and providing a robust guide for decision-making in risk management. Finally, the criteria and alternatives evaluated are presented to demonstrate the functioning and validation of the model, through roundtable discussions with the decision-making group formed. Likewise, the benefits and limitations of this work are recognized.
