Obtención de un Índice General de Seguridad en Pistas Aeroportuarias mediante un Proceso de Ponderación de Criterios Basado en Datos Cardinales

espanolEste trabajo propone un enfoque para obtener un indice global de seguridad operacional en pistas aeroportuarias, con criterios basados en eventos de seguridad. Se ponderan los eventos en base a los datos cardinales extraidos a partir de la percepcion de un experto sobre los riesgos de seguridad derivados de ellos, utilizando el metodo de los pesos dinamicos (Swing Weights). Se ha utilizado la teoria del valor multi- atributo para agrupar los diferentes criterios en un indice global, con el fin de analizar la evolucion de los niveles de seguridad. Este enfoque se aplico a las operaciones del Aeropuerto Internacional de Sao Paulo- Guarulhos. Se realizaron analisis de tendencias con el fin de poner de relieve los indicadores con mayor urgencia para llevar a cabo acciones encaminadas a aumentar los niveles de seguridad. Los resultados fueron considerados consistentes, lo que contribuye a la continuidad de su aplicacion practica en la gestion de la seguridad del aeropuerto. EnglishThis paper proposes an approach to obtain a global index of safety in airport runways, with criteria based on safety events. Events were weighted based on the cardinal data extracted from the perception of an expert on safety risks, using the Swing Weights method. The multi-attribute value theory to group the different criteria in a global index was employed to analyze the evolution of the safety levels. This approach was applied to the operations of the Sao Paulo-Guarulhos International Airport. Trend analyses were done to highlight the most urgent indicators to carry out actions to increase the safety levels. The results were considered to be consistent, contributing to the continuity of its practical application in the management of airport safety.

A multicriteria model to evaluate airport ramp safety: A study at São Paulo International Airport

ABSTRACT This paper presenting as contribution a model for the evaluation, control, and improvement of airport safety by analyzing different operational events. This model is based on multicriteria methods, in particular, the entropy and TOPSIS methods. It allows to operationalize the evaluation of the airport ramp safety performance in contexts of scarce information about the weights of each criterion, and where the absence of personal judgments in the weighting process is considered important. Operational events were used to develop the criteria. In addition, an application was conducted and the data from airport ramp safety events were used to identify trends, diagnose problems, support the planning of actions, and provide a basis for allocating resources for prevention of catastrophic accidents and improvement of safety. This application was used to validate the model. It was concluded that the airport ramp safety did not maintain a trend of continuous improvement and the proposed model allowed the identification of trends, of criteria with low performance, and the realization of recommendations for improvinge airport safety.Keywords: Safety indicators, TOPSIS, entropy, airport.
