Abstract
This article describes methods for safety integrity level (SIL) verification of safety-related functions with regard to probabilistic criteria given international standards IEC 61508 and IEC 61511. These functions are to be realized using the electrical, electronic and programmable electronic (E/E/PE) systems or safety instrumented systems (SIS). Some methods are proposed for quantitative probabilistic modelling taking into account potential dependent failures in redundant systems with divers channels within subsystems. The analyses of safety-related systems include testing and maintenance planning of subsystems, in particular the sensors and actuators with regard to the probabilistic criteria defined for given SIL. The methods are illustrated on some examples of systems from hazardous industry sector.
