Risk Assessment Method for Guaranteeing Safety in the Train Control System

초록

Recently, failures of equipments are linked directly to extensive damages of human lives or financial losses from the increasing uses of train control equipments utilizing computers. Then safety activities have to progress for guaranteeing safety during the system life-cycle. In this paper, we examine the methods for risk analysis and assessment of safety activities and propose optimized one method for risk estimation. In the comparison of risk graph and risk matrix method for safety estimation, proposed BP(Best Practice)-risk method combines the most beneficial properties of commonly used approaches.
