SIL allocation of SIS by aggregation of experts' opinions

Résumé

This paper deals with a process of subjective evaluation to collect imprecise and uncertain experts' opinions with fuzzy numbers as possibility distributions. These opinions are aggregated in the framework of possibility theory. The risk graph logic is translated in a fuzzy inference system in order to compute SIL level. Aggregation of opinions is shown in different cases and the SIL allocation process is applied to an example found in the standard.
