Founder of the Systems Analysis Laboratory

was appointed Professor of Applied Mathematics at Helsinki University of Technology (now part of Aalto University) in 1981. He established the in 1984. It has become an internationally recognized research unit and has had a strong national impact in educating operations research professionals for important positions in the Finnish industry and society.  Professor Hämäläinen has a high number of citations for his over 200 publications, and has supervised over 40 doctoral graduates. In 2017 he was also appointed an Honorary Visiting Professor in the Loughborough University, UK.

The Ramsey medal was awarded on 21 October at the INFORMS conference attended by six thousand operations research scholars in Seattle. The conference is an opportunity for the global operations research community to come together to discuss their current research, and they will also be taking time to celebrate Professor Hämäläinen’s distinguished work for the past three decades.

New research area - Behavioural Operations Research

‘My most recent research interests focus on people. I am collaborating with Professor Esa Saarinen in Aalto in developing the concept of Systems Intelligence. The discipline of operations research is about problem solving and there the human component is also essential. We coined the term and defined a new research area in 2013 and subsequently this has emerged as a very active new field internationally. We need to acknowledge that we modelers as well as any other people have multiple cognitive biases. Psychologists are always finding more but we in operations research are trying to come up with ways to mitigate the effects of biases in decision making,’ said Professor Hämäläinen.

Professor Jason Merrick, the chair of the medal award committee said in the statement announcing the prize “Dr. Hämäläinen has an outstanding record as a scholar, focusing on multicriteria decision analysis and related behavioral issues, and as an academic leader of several groups in Finland and Europe.”

‘People´s values  need to be represented in decisions’

Whilst the prize is a celebration of past work, Professor Hämäläinen is still looking to the future, where he sees important questions over the prominence of Artificial Intelligence in decision making. ‘There is a little bit of a blindness going on with respect to AI – it is seen as a magical silver bullet that solves everything. AI can learn by crunching numbers, but decision-making takes numbers and works with people. People´s goals and values also need to be represented in the decision being made”

Professor Hämäläinen has already won honors in Finland and globally. He was invited a member of the Finnish Academy of Technology in 1985 and was named Honorary President of the Finnish Operations Research Society in 2008 for his contributions in developing the field of Operations Research in Finland. He also won the MCDM Edgeworth-Pareto Award, the highest award for career contributions from the International Society on Multiple Criteria Decision Making, which has subsequently also been awarded  this year to his former student today another Aalto university Professor, Ahti Salo.
