System to build, analyze and manage a computer generated risk assessment model and perform layer of protection analysis using a real world model in software of a safety instrumented system architecture

摘要

A system to build, manage, and analyze a computer generated risk assessment model and perform a layer of protection analysis. The system uses a computer generated safety instrumented system model for managing a process safety lifecycle for a safety instrumented system in a facility. The computer generated safety instrumented system model has at least one instrumented protective function.
