01 / FUNCTIONAL MODELLING
Model how work is accomplished
Functional System Modelling reveals the activities, dependencies and conditions through which real systems produce both successful and unwanted outcomes.

What we do
A research and innovation hub for safety science.
Cambrensis brings together systems thinking, quantitative analysis and operational evidence. We develop methods, working models and research partnerships that help people examine complex sociotechnical systems with greater clarity.
02 / QUANTITATIVE ANALYSIS
Explore variability and uncertainty
We develop transparent analyses that connect functions, operational data, assumptions and simulation to test how system behaviour changes across conditions.
03 / INCIDENT INVESTIGATION
Reconstruct events as system behaviour
Structured investigation combines evidence, functional modelling and disciplined inquiry to explain what happened, how it emerged and why existing controls did not resolve it.
04 / AI-SUPPORTED APPLICATIONS
Make advanced methods usable
We design governed AI-supported tools that help analysts assemble evidence, build models, explore scenarios and retain an auditable line from source to conclusion.
An evidence-led approach
From system definition to useful action.
FrameDefine the system, purpose, boundary and questions.
ModelRepresent functions, couplings and operating conditions.
ConnectLink documents, observations, data and uncertainty.
ExploreTest variability, scenarios and alternative explanations.
LearnTranslate findings into decisions, trials and further research.
Application domains
Where complexity has consequences.
Our work concentrates on settings in which performance emerges from interactions between people, technology, organisation, information and changing operational conditions.
Care systems
Healthcare
Patient flow, bed occupancy, clinical work, incident investigation and the resilience of services under pressure.
Operational data
Aviation & flight analysis
Functional interpretation of flight data, actual-versus-expected performance and evidence-led examination of operational events.
Major hazards
Process industries
Functional HAZOP, barrier performance, plant operations and quantitative exploration of how deviations propagate through complex systems.
Under controlled evaluation
From operational data to system understanding.
FRAIXL connects data from different sources to a functional model of how the system works. It helps users see why changes matter, how effects propagate and where recovery or intervention may be possible.
FRAIXL is being developed as a governed agentic AI workbench. Its agents help analysts organise evidence, build and refine functional models, map operational data and examine results from controlled analyses. Analysts review proposed models, assumptions and findings, while supporting evidence and analysis history are retained.
We are developing the same core approach for healthcare, flight-data analysis and process industries.
Selected supervised trials will test how well people outside the development team can use the workbench.

Building the work around the problem.
Cambrensis convenes the combination of operational, academic, technical and domain expertise that complex safety questions require.
Research consortia
We are exploring research consortia in three areas: healthcare systems, flight-data analysis and process industries. Each would bring operational evidence together with a functional model to examine how the system performs. We welcome interest from researchers, practitioners and organisations with relevant questions, expertise or suitable data.
Express your interest ↗International conferences and workshops
We organise focused events that bring researchers, practitioners, regulators and technology partners together to examine methods, cases and emerging applications.
Research & insights
Ideas made open for examination.
Our papers, working notes and essays explore the foundations, limitations and practical development of safety science.
