Abstract

This paper summarizes the D_RAMP safety analysis methodology and demon- strates a typical application to a system. The safety is quantified in terms of the Mean Time Between hazardous Event (MTBHE). The summarized safety anal- ysis shown the necessary conditions to prove the MTBHE > 1x10^ years. 1.0 Introduction The Union Switch & Signal has been developing a tool to be used for the verifi- cation and validation, concurrent with the design of Real Time Computing Sys- tems (RTCSs). This toolkit is called D_RAMP (Design for Reliability, Availability, Maintainability, Performance and Safety). D_RAMP plays a cen- tral role in the V&V methodology and constitutes a novel approach to accessing and quantifying the
