Dependability of computer railway automation systems

Abstract

IT development contributes to the fact that this technology is used in many fields concerning the economic and social life. It also contributes to a fast technological development of railway automations systems that are computer systems nowadays. Progress that undoubtedly must be noted, has to be followed by maintaining by these systems high quality standards, resulting mainly from ensuring safety. Such condition can be achieved, among others, through integrating works connected with reliability and security, by aiming at achieving dependability of the systems. This article presents the problem of the dependability of railway automation systems understood as their operating reliability, which allows to trust tasks accomplished by these systems.
