Abstract
This paper presents a probabilistic safety management framework for control laws to provide a balance between normal-case performance, safety and fault-case performance according to the international standard on safety, IEC 61508. It is based on multiobjective design for simultaneous problems for each context to optimize only normal-case performance out of the whole including fault-case performance. Also the framework establishes the existence of trade-off between them quantitatively for the first time ever.
