Designing Control and Protection Systems with Regard to Integrated Functional Safety and Cybersecurity Aspects

This article addresses current problems of risk analysis and probabilistic modelling for functional safety management in the life cycle safety-related systems. Two main stages lifecycle these systems are distinguished, namely design operation. The differ view available knowledge data. Due to complexity uncertainty involved, both qualitative quantitative information can be useful modelling. Some methodological aspects assessment outlined that include dependent failures or cybersecurity verifying integrity level (SIL) under uncertainty. It is illustrated how assumptions process influence results obtained and, therefore, potentially decisions taken management. Programmable control play an important role mitigating controlling risks operation hazardous installations. paper presents ways deal with hazards involving such considered integrated
