Operational fault states in railways
Andreas Schöbel, Thomas Maly · European Transport Research Review · 2012
In railway systems, there are many different fault states which can occur during operation. For safety reasons, these well known fault states have to be prevented by train monitoring. But fault states may also have dependencies among each other, which are not sufficiently known yet or used for fault state prevention. Thus, in a first step an abstract approach has been developed for the description of dependencies. Based on this and as systematic description of all relevant states and their dependencies a fault state matrix has been created, which is considered in this paper.
