We are currently 18 researchers, some of whom also work as senior software engineers. For more than 20 years, we have been developing optimisation methods, software prototypes, libraries and components, and we have built a strong international level of competence and publication record in optimisation. Our software libraries contain a range of different solution methods (exact and approximate) that have been refined over many years. (We do work with the main commercial solvers as well.) In recent years, we have also developed our own discrete event simulator. We conduct basic and applied research on
- and timetabling problems.
Our main market areas are transportation: road, maritime, and aviation; healthcare; sports; building and infrastructure; and finance. We commercialise our results through spin-off companies and software vendors and sometimes sell directly to end users (industry and the public sector).

Currently, maintenance planning in the railroad domain is predominantly performed manually and involves: Crew scheduling (assigning maintenance tasks to crews dependent on skill set) and job shop scheduling (assign time slots for vehicles to depot workstations). These activities should be synchronised and coordinated with vehicles revenue generating activity (where the vehicles are scheduled to transporting goods or passengers). Due to the substantial fixed costs involved, improved planning is expected to generate significant cost savings.
We are the research partner in Space Makers innovation project OptiSite where we try to optimise the best use of a large building site while consider a range of constraints and objectives.
The CO2REOPT project aims at developing methods and tools for full external transport integration where suppliers, manufacturers and customers share a fully integrated and optimized intermodal supply chain.
The goal of the SmartPower project is to demonstrate the usefulness of modern optimisation methods for demand respons applications in energy market. To this end, we develop a prototype for optimised Power Matching/load balancing in large scale Smart Grids, a highly complex optimisation problem.
Next Generation Decision Support Tool
Enabling better collaboration between humans and decision support systems in time-critical complex domains
DynamITe competence project
New optimisation models and solution algorithms are needed to develop systems and services for intermodal personal itinerary planning and vehicle routing that handle dynamics effectively and efficiently.
This is a large industrial project between Nobina AB in Sweden and SINTEF Optimisation. The project focuses on building a personnel scheduling engine - SkiftOpt - that matches bus drivers to shifts. The engine creates a work schedule for personnel by matching bus drivers to shifts for a given planning horizon while considering skills, competence, fairness, laws, regulations, as well as the bus drivers' preferences. The output is a schedule of the working hours for the drivers. In 2016, the new system with the SkiftOpt engine inside was rolled out in Sweden. In 2017, the plan is to roll out the engine in Denmark and Finland.
The BONVOYAGE project aims at designing, developing and testing a platform optimizing multimodal door-to-door transport of passengers and goods.
SPORTING aims to take sports scheduling from the current fragmented, unsatisfactory and obsolete state to a unified, efficient and user-centric future. It will make Profixio a global leader in the sports scheduling market thanks to an innovative sport scheduling software based on state-of-the-art mathematics optimization and a innovative graphical user interface.
Norwegian researchers make European air traffic more efficient
Many major European airports are unable to expand. This means that aircraft departures, arrivals and surface movements will have to be speeded up. A Norwegian system designed to make all airport movements more efficient is tested in Hamburg, and at Arlanda in Stockholm and Charles de Gaulle in Paris.
Optimal fixture scheduling
With help from SINTEF, the northern Norwegian company Profixio is aiming to become a world leader in fixture scheduling for handball, football and volleyball tournaments.
