1. Innovation- and research programmes at TU Delft Safety and Security Institute (DSyS) June 8th 2017 HSD Cafe Pieter van Gelder

2. Safety and Security Science
Is about scientific analysis of undesired events (intentional and unintentional)
At TU Delft we aim to quantify and optimize safety and security by technical and socio-technical measures.

4. We are always looking for cases
Research goals
How to improve the risk management methodologies?
How to improve the data analytics?
How to improve the system of systems approach?
Bayesian networks
Machine Learning / AI
Normative questions
Algorithmic issues
MCDM
We are always looking for cases

5. Bow-tie Model: BUT: Everything leading up to the accident
Everything following the accident
Fault tree
Event tree
BUT:
Logic is NOT deterministic
Causality is probabilistic
Human influence certainly not deterministic
New sort of construct: Bayesian Belief Net
Barriers

6. BBN for road infrastructure
There is an arc from EWE to node Qi, which is the intensity of flow at the location of bridge Bi
Each Qi has three states, namely State0, State1, and State2, denoting low, medium, and high intensity flow
Each bridge Bi has only two states, namely State0 and State1, representing the failure
and operation of the bridge

7. CATS Causal Model for Air Transport Safety
1400 nodes
