Monte Carlo analysis for safety and reliability of rail transit signal system based on Cloud Computing

Abstract

Abstract Starting from the hot issue of introducing cloud computing into rail transit industry, this paper analyses the impact of cloud computing virtualization technology on the safety and reliability indexes of rail transit signal system, Monte Carlo method is used to model two out of 3,double two out of two and two out of two redundant structures from three main parameters of common cause failure,fault diagnosis coverage rate and dangerous failure rate, considering the uncertainty of relevant parameters. The reliability and safety indexes are calculated and simulated with MATLAB. The results show that the two out of three structure is more suitable for the rail transit signal system based on cloud computing.
