How does SIL Solver® do the calculations?
SIL Solver® is an advisory software package intended for use in the verification of the Integrity Level (IL) of Protective Instrumented Functions (PIF) commonly encountered in the process industries. SIL Solver® utilizes reliability block diagrams with fault tree equations to calculate the probability to fail on demand (PFDAVG) and the MTTFspurious of the protective instrumented function (PIF). SIL Solver® uses globally recognized standards and methodologies to analyze components, subsystems, and PIFs, such as: ANSI/ISA 84.00.01-2004 (IEC 61511) ISA TR84.00.02 IEC 61511 IEC 61508 SIL Solver® is capable of analyzing PIF with multiple input and output elements, tested at different intervals, including partial stroke testing of valves, and includes a device failure rate database.
