Since the last years, the electro-mechanical systems for route-setting are being replaced worldwide with computer-based interlocking system. The replacement typically requires significant interventions for substituting existing electro-mechanical systems up to the railway-yard where the point switches, light signals, track circuits, etc., remain unchanged.

Abstract
Since the last years, the electro-mechanical systems for route-setting are being replaced worldwide with computer-based interlocking system. The replacement typically requires significant interventions for substituting existing electro-mechanical systems up to the railway-yard where the point switches, light signals, track circuits, etc., remain unchanged. The significant changes, allow a significant simplification of the connection network between devices and control apparatuses thus making communication more reliable and processing nucleus dimensions drastically reduced. However, the resulting overall complexity of computer-based procedures makes necessary analyses on the system as a whole. Therefore a reliability analysis of the new system seems essential jointly with a right choice of modelling methods. The present paper illustrates the reliability and availability analyses performed for the new computerised interlocking system implemented for controlling the Roma Termini railway station traffic.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
