Risk-informed decision-making

How should we act under uncertainty?

Infrastructure decisions combine uncertain outcomes with competing objectives and limited resources. We study how information and stakeholder behaviour influence these choices. Decision-theoretic and behavioural models connect individual actions to consequences for systems and society over time.

Choosing between actions for the same system using available information. Highlighted elements distinguish the actions, and dashed branches indicate uncertain outcomes. Conceptual illustration.

Questions we study

Which action is preferable?

We compare interventions through their costs, avoided consequences, and performance under different future conditions.

How does information change a decision?

Our work examines how knowledge and uncertainty influence choices, including interactions between attackers and defenders.

How do individual choices shape systems?

We investigate how incentives and stakeholder interactions can influence collective behaviour and infrastructure policy.
