| Abstract |
Among safety-related systems that are responsible for the functional safety of an overall system, the share of E/E/PE safety-related systems with embedded software is expanding. Under that situation, there is necessity to discuss the functional safety for the software installed into the E/E/PE safety-related system, not only for the hardware systems. We discuss quantitative software functional safety assessment methodologies for the software of the E/E/PE safety-related systems, which enable us to conduct simulation-based interval estimations of target failure measures even if the size of software failure data is small by applying a bootstrapping method. Numerical examples for our approaches to be proposed here are also shown to demonstrate our simulation-based interval estimation approaches.
