DYNAMIC FAULT ANALYSIS OF LARGE-SCALE TRAFFIC CONTROL SYSTEMS WITH REFERENCE TO COMPONENT'S DETERIORATION

Abstract

In this paper, a dynamic fault analysis model of large-scaled information systems is formulated to investigate the impacts of the system service inoperability upon social systems. The renewal processes of the components of the systems are described by use of rondom Weibull hazard models, and the fault tree model is formulated to analyze the magnitude of the system inoperability. The reliability of the information systems and the expected repair/maintenancce cost estimated by Monte Carlo simulation models. The practical availability of the methodology presented in this paper is investigated by a case study dealing with the traffic control systems for an expressway.
