La fiabilidad humana tiene como objetivo la identificación, cuantificación y análisis de los factores humanos involucrados en los errores de funcionamiento de sistemas complejos. La cuantificación de la influencia de estos factores da lugar a las probabilidades de error humano, cuya estimación es un problema arduo. Dado que dichos factores están relacionados con elementos organizativos y tecnológicos, trabajos previos proponen el uso de modelos gráficos probabilísticos, como las redes Bayesianas o credales. Sin embargo, estos modelos requieren el cómputo de probabilidades condicionadas, lo que puede dar lugar a problemas cuando se condiciona a sucesos que, hasta la fecha, no han ocurrido. Además, las soluciones propuestas hasta ahora combinan aproximaciones frecuentistas y subjetivas, y no son en general robustas. En este trabajo proponemos una alternativa basada en modelos de distorsión, mostrando que el modelo es consistente con las estimaciones previas ganando a la vez en robustez.

Keywords: Fiabilidad humana, modelos gráficos probabilísticos, probabilidades imprecisas, modelos robustos.
