摘要

We can not say that a safety-related system is established, based on the usual method of calculating the software safety integrity level (abbreviated as SIL) in the functional safety standards, which is determined only by the number of development methods applied to practical safety-related system (abbreviated as SRSs). In this paper, we discuss quantitative assessment by applying reliability measurement based on software reliability growth models (abbreviated as SRGM's) that have been widely and successfully applied to practical software quality management activities. Based on a nonhomogeneous Poisson process (abbreviated as NHPP), the plausible method of calculating software SIL in the functional safety standard is proposed.
