RESYGESS
REsilience of Railway Safety Management Systems
The European legal framework, and in particular safety directive 2004/49, introduces the need for rail operators to have a " Safety Management System " (SMS) authorized by a national safety agency (NSA) for a limited period. An SMS provides a systematic and precise description of the company's safety management organization. It makes explicit the organization of all rules, procedures, methods and technical or human means to achieve safety objectives and mitigate the risks of railway activities.
The main challenge is to properly evaluate an "organizational" system involving a large number of factors. The SMS assessment process is often a difficult task as the system is very complex and involves various aspects, such as the characteristics of the rail operator (its organization, safety experience, etc.), changes in the SMS over time, human factors... In this context, the RESYGESS project aims to propose a new assessment framework based on three SMS performance attributes, namely compliance, effectiveness and maturity (abbreviated to CEM). The modeling approach used verifies the completeness and robustness of railway operators' safety management systems, and highlights potential weaknesses (resilience testing). It focuses primarily on the processing of information and decision flows in incident and accident management. This project complements and extends the organizational and systemic modeling developed by LAMIH. (ANR - PIA)
