Research and evidence
The research behind Systems Science and Modelling: the questions it asks, the models and measurements it uses, how uncertainty is stated and how a result is reviewed and reproduced before it is published.

What the research asks.
- 01
Model intercomparison
Comparing models of the same system, and what disagreement tells you.
- 02
Uncertainty and validation
Quantifying uncertainty, validation against observations and the limits of calibration.
- 03
Coupled systems modelling
Linking water, energy, food, health and infrastructure models without hiding assumptions.
- 04
Networks and cascades
Network science for dependency, contagion and cascading failure.
- 05
Agent-based and complexity models
Behaviour, adaptation and emergence in social-technical systems.
- 06
Optimisation under uncertainty
Robust and adaptive decisions when futures are deeply uncertain.
What systems modelling research cannot yet answer well enough for decisions.
Systems modelling research asks how to couple models of different systems without hiding uncertainty or inventing precision.
- How should models from different fields be coupled so that their assumptions are consistent? See coupled systems modelling.
- What validation is possible for models of events that have not happened? See uncertainty and validation.
- How can model intercomparison expose structural uncertainty in cross-sector impacts? See model intercomparison.
- What makes a digital twin a valid method rather than a visualisation? See digital twins as method.
Every result keeps its label.
Results are labelled as observed, published statistics, estimated, modelled, forecast, scenario or expert judgement. Missing data is shown as missing, never filled silently.

Reports is the Consortium’s quarterly publication. What you know about this subject can become evidence, a case or a correction in the next edition, credited to you and published under CC BY 4.0 where it is your own work.

Never send personal data, sensitive infrastructure detail or anything you have no right to share. A contribution is reviewed before use; sending it confers no authorship or editorial rights, and sponsorship never buys a finding.

Information and enquiries are open today. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
