Creating Cross Organisational Safety Management: Possibility of Public-Private Safety Collaboration

This research focusses on finding an answer to the question how can safety be improved in a public-private environment. By means of literature and a case study some improvement opportunities are identified, which pose promising opportunities for improving safety management. The research focused on one of the opportunities, a collaborative...

Droughts and Decisions: Pastoralism, Decision Junctures and Rain Forecasting

The livelihood of the Maasai pastoral communities in Longido District of Northern Tanzania are impacted by droughts regularly, with expectations of increasing variability in rainfall patterns the coming years due to climate change. The goal of this research is to explore if weather forecast and remote sensing data can be tailored to existing...

Using the Participatory Value Evaluation methodology to discover influences of risk acceptance on preferences for risk mitigation: A case-study on gas induced earthquakes in Groningen

Recent years the Netherlands have been shocked by a series of earthquakes. Normally an earthquake would be considered as a natural hazard, however extracting gas induces these earthquakes. Whenever a hazard is induced, it is perceived as man-made and therefore controllable. This leads to differences in risk acceptance in relation to natural...

Safety through Machine Learning Applications: A Safety Case Analysis

Machine learning applications are increasingly being implemented in socio-technical safety-critical systems, but the safety of these applications is not well understood. This thesis used a mixed-method design and applied four methods to explore the field of machine learning and safety. With the results of these four methods, a framework was...

Simulating ecosystem-level cybersecurity for the future generation of critical infrastructures: Exploring the impact of cyber-defensive strategies on critical infrastructures through agent-based modelling

The increased decentralisation and heterogeneity of critical infrastructure systems pose a threat to the safe and secure operation of critical infrastructures by complicating cybersecurity procedures. The increased frequency and impact of cyberthreats have led to the desire to develop coherent security policies. In order to explore the effects...

Risk allocation between private parties in European Public-private partnerships for social infrastructure projects

In this research, a dichotomy between two different risk approaches is presented. One approach depicts risk management and a subpart of it, risk allocation, to be objective. The other approach contradicts this approach by stating that all stages of risk analysis, including its techniques involve subjectivity (Redmill, 2002). The ‘dual nature of...

Probabilistic downtime analysis for complex marine projects: Development of a modular Markov model that generates binary workability sequences for sequential marine operations

A complex marine project consist of series of operations, with each operation subject to a predefined operational limit and duration, depending on the equipment being used. If actual weather conditions exceed the operational limit, then the operation cannot be executed and hence downtime occurs. It is up to contractors, such as Boskalis, to...
