Comparative Study of the Reliability of a Moroccan Level Crossing System Using Belief Function Theory and Imprecise Probabilities

摘要

The Levels Crossings (place of crossing of a railway by a road) are one of the most important sources of accidents in the railway sector in Morocco. For this reason, the National Office of the Moroccan Railways (ONCF) has launched a program which aims at removing hundreds of Level Crossings because of their dangerousness. This paper presents a comparative study between the belief function theory and the imprecise probabilities so as to evaluate the reliability of the Moroccan Level Crossings system over the time by integrating human factor and components failures data uncertainty.
