Research group Optimization


Contact person

Our expertise is in mathematical decision-making at scale, with key topics being planning, scheduling, routing, sequencing, design and timetabling. Companies and organizations increasingly need both decision support and automated decisions, and with our decades of experience in optimization and operations research we solve new questions in these areas and help make innovation possible. We have broad experience in the full range of methods, like exact optimization, decomposition methods, metaheuristics and matheuristics.

We develop our own software libraries that have been refined and extended over many years and contain a variety of solution methods, but we also utilize commercial solvers. Our results are exploited, either through existing solution vendors, spin-off companies, or directly by the end users. Our revenues come from users in industry and the public sector, often supported by Norwegian or EU funding agencies. The group is internationally renowned both in industry and academia. We publish actively, also in top level scientific journals.

While applications are dissimilar, the same methods can often be applied in a broad range of situations, and therefore we apply our skills in a wide range of domains. Below is a selection of our market areas, projects and software.

Mathematics as a means to stop snoring

A flag waving in the wind can illustrate what we call "air-solids interaction". When the wind hits the top of the flagpole the flag dances to the wind's rhythms, often in complex ways.  And as we all know: it takes two to tango. The air-flow is also...
