The modern world’s backbone engineering systems are becoming increasingly complex and connected. Many of our critical infrastructure ecosystems are comprised of interdependent sub-systems, each governed by complex non-linear dynamics and cascade interactions.
The CoTRE project (Complexity Twin for Resilient Ecosystems) will build a mathematical mirror to the UK’s critical infrastructure ecosystems. The ‘complexity twin’ will be a world first attempt to understand the resilience of large-scale complex systems that increasingly face threats from nature and human activity. This work will address the fundamental theoretical aspects of the stability of complex systems and work with a variety of critical infrastructure operators to develop resilience investment strategies, with the aim of improving critical infrastructure safety.
The project is funded by EPSRC under the Engineering for Prosperous Nation call.
CoTRE will develop a generalised complexity model of interdependent complex critical infrastructure (CI) ecosystems. The project aims to improve uncertainty quantification and decision-making processes. The project will leverage pre-existing CI operators to perform data-driven validation and translate resilience science into industrial impact to sustain the research beyond the two-year lifecycle. To ensure this, the CoTRE project has the following objectives:
- Develop generalised low-dimensional resilience measures for high-dimensional complex CI ecosystems, linking functional resilience of subsystems to topological resilience of the whole network.
- Engage CI operator stakeholders to translate fundamental resilience science into actionable operational algorithms and investment advice.
In addition, the project aims to promote industrial and public awareness of connected resilience by demonstrating the UK national CI systems on a public interactive interface.
