HFES Nordic: Rasmussen Redux
IDA Conference, København. Tuesday 21 April 2026. 08:30 – 16:30
The Nordic chapter of the Human Factors and Ergonomics Society (HFES Nordic) is delighted to invite you for a special one-day meeting in Copenhagen on Tuesday, April 21, the day before the start of the HFES Europe conference.
The symposium analyzes the legacy of Jens Rasmussen and the application of his ideas in contemporary and novel human factors research. Marking the centenary of his birth, the meeting throws light on the unique cross-disciplinary environment at Risø where Rasmussen and colleagues developed models that remain relevant today to safety critical domains including healthcare, transport, offshore and process industry,
For five decades, the Risø group’s concepts have influenced human factors theory, system safety, and sociotechnical system design. From the Skills-Rules-Knowledge framework to the Abstraction Hierarchy and Ecological Interface design and from AcciMaps to the dynamic safety model, concepts developed at Risø in the 1970s and 80s continue to inform research across multiple domains.
The morning programme outlines the work at Risø and connects it to parallel developments in cognitive science and systems thinking. Speakers will discuss these topics and their historical context.
The afternoon session focuses on current and future applications. Speakers from industry and applied research will demonstrate how Rasmussen’s ideas are currently used in interface design, human reliability, risk assessment, control room studies, and accident investigation.
The symposium welcomes both experienced practitioners and those new to these foundational ideas. The event includes ample opportunities for networking, followed by a Copenhagen canal cruise and symposium dinner.
Organizers: The symposium is organized by HFES Nordic (The Nordic chapter of the Human Factors and Ergonomics Society) and IDA Risk, in collaboration with DSKS (Danish Society for Healthcare Quality) and SimTrans.
