A Kaufmann reliability network approach based on components off-the-shelf to design Safety Instrumented Systems
Résumé
This paper deals with an approach to design a Safety Instrumented System with the aim of reducing design costs under availability constraints. The design involves the determination of the SIS structure and the allocation of equipment availability and redundancy based on Components off-the-shelf. The SIS structure is interpreted as a p-graph and handled as a Kaufmann reliability network. The optimization approach is genetic method applied to several design problems of increasing complexity.
