Towards a computer-aided assessment of railway system preliminary hazard analysis
Résumé
Preliminary hazard analyses (PHAs) lack a precise and sound definition of their vocabulary, method and presentation format. The purpose of the work described in this paper is to improve the production and assessment of PHAs by providing experts with a software assistance. This paper presents the first stages of the study. These are: the definition of a basic vocabulary for PHAs, the definition of a new method for PHAs, the design of a tabular presentation of the results and, finally, the design of the software assistant architecture.
