Abstract

Safety is a concerned point in today’s railway control system. Historical evidence on railway control system failure makes a matter of concern on safe control system. In this paper, we present a use/misuse case based safety framework for a railway control system with integrated safety analysis. The framework comprises of two major processes i.e. use/misuse case based requirements modelling and application of integrated safety analysis techniques. First, the use case and misuse case specification analyze all the system function and identify possible failures. Second, integrated safety analysis techniques evaluate the specification, identify hazards and propose the mitigations. This paper analyses the railway control system reliability using Unified Modeling Language (UML) and followed by integrated safety analysis techniques such as Hazard and Operability Study (HAZOP) and Fault Tree Analysis (FTA). This approach has been systematically applied to study two different domain in system reliability and system control based on human interaction. We demonstrate how an applicability of UML specification is integrated with safety analysis techniques for the development of safe railway control system.
