Analysis of Related Factors Influencing Reliability of Railway Signaling Systems Based on Fuzzy Analytical Hierarchy Process

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 288)


A signaling system is a safety-critical part of railways. Most of the railway signaling systems currently used today are intelligent and automatic high-performance systems, for which the high level of reliability is required. However, there are many factors including those uncertainties that affect system reliability performance. In this paper, fuzzy analytical hierarchy process is further developed by using hierarchical structure to determine weights of contributions of each factor and subfactor to the reliability performance of the system. By using the proposed methodology, the results of reliability analysis indicate that the reliability of a signaling system can be assessed effectively and efficiently.
