    Fuzzy electre model for the characterisation of aeronautical operational risks in the approach and landing phase
    (Universidad EAFIT, 2023) Leal Cabra, Estefanía del Pilar; Peña, Juan Alejandro
    One of the significant challenges facing the aviation sector is the management of risks arising from its flight operations, especially in the approach and landing phases, where pilot experience and training are of great importance and where the most significant incidents for air safety occur. Therefore, this paper proposes a model inspired by the structure of a Fuzzy ELECTRE model for managing the operational risks that arise in the approach and landing phases that can lead to safety events. Thanks to the analysis of the literature collected, the management criteria and risk parameters to be taken into account for these two flight phases were shown following air safety manuals such as the International Civil Aviation Organization (ICAO) manual, and where the data obtained was obtained qualitatively thanks to the implementation of surveys with expert pilots, whose information served as the primary input for the characterisation of risks. Following the structure of the proposed model, five (5) reference risk scenarios management were constructed using the previous information, and an analysis of the dominance and discrepancy of a risk scenario vs. the previously established reference scenarios was carried out. Finally, it can be concluded that the proposed model allowed the quantitative-qualitative characterisation for managing the most relevant risks in the approach and landing phases, integrating the expertise of experts in this area.

    Operadores responsables : del modelo EAST a la norma social
    (Universidad EAFIT, 2022) Cáceres Escobar, Piedad Paola; Hernández Cañola, Liza María; Galeano Arias, Felipe; Vélez Zapata, Sara
    The objective of this intervention was to identify how people's perception of their role changes, based on actions proposed by behavioral sciences, seeking to reinforce the stereotype of responsible operators in collaborators of power generation plants in a power generation company. the city of Medellin. For the implementation, a design was used under the EAST model seeking to mobilize the social norm, with pre and post evaluation of the results, which showed that the perception of people can change from interventions in which their context is considered, allowing the installation of behaviors based on new social norms that promote the adoption of safe practices within the operation. This change can be generated from messages that operate as Nudges after the segmentation of the population and the knowledge of the perceptions about the role of the operator in hydroelectric plants, thus facilitating the recognition of elements that promote the social norm.
