A Study on the Failure Mode Identification of Railway Signaling Embedded System

This paper is about the study on the failure mode identification of railway signaling embedded system thru which quantitative reliability and safety can be compared reciprocally. Frequency of each failure mode makes possible to compare the reliability of each system and frequency of dangerous failure is used as the measurement standards for system safety. Therefore, this paper provides both reliability-related failure mode and safety-related failure mode by modeling the railway signaling embedded system.
