Five pillars, one mathematical core, three ways of working

A pillar is a research field with its own questions, projects and publications. Methods are shared and described once. Anything that is a property of all our work is a dimension of how we work — not a sixth pillar.

Foundation

The methodological core

Six competence groups shared by every pillar: mathematical modelling and econometrics; soft computing and artificial intelligence; statistics and data processing; operations research; traffic modelling and simulation; and impact assessment, validation and virtual testing.

They are described once, in one place, so that a partner reading this site sees a single consistent answer to the question of what we can do.

Cross-cutting dimensions

Properties of everything we do

These are not pillars. They are the character of the work, and they show up inside all five fields.

Sustainability and resilience

Networks optimised purely for efficiency are fragile. We quantify the trade-off through a four-phase assessment — prevent and prepare, absorb, adapt, recover — rather than asserting it. RESISTRANS is the platform where this happens at national scale.

Science for policy

An indicator that never becomes an instrument someone can act on is unfinished work. Concretely: a methodology endorsed by a ministry, a control system in daily operation, a decision toolset in a municipal control centre, and a granted patent.

Human-in-the-loop and explainability

Operators and regulators reject systems they cannot interrogate, and they are right to. A liability question after an incident is answered with an explanation, not an accuracy score — so our AI and our twins are built to be interrogated.

This site is the short form. The full evidence dossier — every project with its grant number and budget, every publication with its DOI, and the figures at full resolution — is available on request.
