HIGHER AVAILABILITY -- A RESULT OF INFLUENCE OF SYSTEM MAINTENANCE
Reliability and availability are important criteria for traffic control and railway signaling systems. Both traffic safety and functionality must be considered. The paper discusses the problem in terms of interaction of maintenance and system components, using Boolean and Markov models of reliability. Both methods are briefly compared with each other. The possibility of the use of either method is discussed. Real reliability data are used which were obtained by examination of transportation systems in action. A mathematical analysis of the basic model shows the influence of the reliability of elements, of the structure of systems, and of maintenance.
