Announcing our 12th and 13th speakers for this years’ annual Risk Forum 16th and 17th September…
Chris Harrison – The Rail Safety and Standards Board
Ruairí Kennedy – CRA
Topic: Modelling Uncertainty in the Railways
In the first part of this presentation Chris will look at some of the different ways that uncertainty has been taken into account in the RSSB Safety Risk Model (SRM). The SRM accounts for both high frequency events where traditional statistical techniques can be applied and low frequency events where a more expert judgement driven approach can be applied. The talk will focus on the application of these methods to the passenger derailment event tree from the SRM, with an explanation of the methodology and analysis applied, along with some examples of the results obtained.
In the second part of the presentation, Ruairi will take a close look at failures in worksite protection. He will show how he dealt with uncertainty in analysing the risk from these failures and will present the resultant cost benefit argument for change.
