Allocation rules of Safety Integrity Levels in a generic TCMS application
Résumé
This article identifies and formalizes specific rules implicitly used for SIL allocation in TCMS (Train Control and Monitoring Systems). Firstly, the context of the SIL (Safety Integrity Level) used within the harmonized risk management process for railway systems in the European Union is presented. Then, the SIL allocation rules in different domains are examined in order to identify specific rules. A generic TCMS application is examined in term of SIL allocation to safety functions results.
