| Abstract | We discuss quantitative software safety assessment based on the safety integrity level (SIL) of IEC 61508, which is the international standard for the functional safety of electrical, electronic and/or programmable electronic (E/E/PE) safety-related systems. On the safety assessment for the E/E/PE safety-related systems, SIL is widely applied as a graded measure representing the safety integrity of E/E/PE safety-related systems. We discuss stochastic modeling for conducting SIL-based safety assessment for the software of E/E/PE safety-related systems by applying the notion of software reliability modeling and assessment method. And we show numerical examples for explainning how to use our approaches.
