abstract: Incorporating safety in the software architectural design decisions is important for the successful applications in safety-critical systems. However, most of the existing software design rationales do not consider the quantitative aspect of the software architectures with respect to safety. As a result, alternative architectures cannot be compared adequately with respect to safety. In this paper, we present an analytical approach for quantifying safety in software architectural designs. We use the concept of architectural service routes to quantify system safety in terms of software architectural attributes. We show how to make appropriate architectural design decisions based on their impacts on safety. We compare different example architectures with respect to system safety.
