“…Rather it is a depiction of the logical interrelationships of basic events that may lead to a particular undesired event. 9,11 In this paper, a full FTA study is not advised as the method can be very cumbersome and tedious. Instead, the technique provided by the method is used to check whether a certain type of failure is possible or not.…”

Application of active suspensions in high-speed passenger trains is gradually getting more and more common. Active suspensions are primarily aimed at improving ride comfort, wear or stability. Failure of these systems may not only just deteriorate the performance but it may also put vehicle safety at risk. There are not many studies that explain how a thorough study proving safety of active suspension should be performed. Therefore, initiating this type of study is necessary for not only preventing incidences but also for assuring acceptance of active suspension by rail vehicle operators and authorities. This study proposes a flowchart for systematic studies of active suspension failures in rail vehicles. The flowchart steps are solidified by using failure mode and effects analysis and fault tree analysis techniques and also acceptance criteria from the EN14363 standard. Furthermore, six failure modes are introduced which are very general and their use can be extended to other studies of active suspension failure. In the last section of the paper, the proposed flowchart is put into practice through four failure examples of active vertical suspension.

“…As a whole, only about 30-40% of large software projects that are initiated will run to completion (Brooks, 1995), and this was one that did not. Even though the record in manufacturing systems-which are highly structured-is probably better than this average, it still could benefit from substantial improvement (Place and Kang, 1993-selected references from older literature have also been repeated here). Startups of new manufacturing and process plants are often notoriously delayed.…”

“…One of the main challenges in these safety-critical systems is how to guarantee that the incoming data streams are processed under strict timing constraints, while jointly providing strong dependability guarantees in terms of high availability and failure resiliency [14]. Clearly, in order to ensure adequate fault-tolerance levels, proper mechanisms need to be employed across all the tiers (i.e., sensors, sinks and back-end) of the data acquisition system.…”
