This report summarises FOI's 2006 activities within the research area "Support to Assessment, Evaluation and Analysis", which is linked to the Swedish Armed Forces taskings (to FOI) covering Direct OA Support and Assessment and Method Development. The former task is carried out using Operational Research groups placed within the Swedish Armed Forces HQ, and the latter task is carried out using project teams based at FOI. The Operational Research groups have supported long term planning, strategic and operational planning, force concept development, exercises and missions. The FoRMA project has during 2006 provided additional analytical support to long term planning. The OA Methods project has supported the OR-groups with development and evaluation of models and methods, with the aim of meeting immediate and long term needs. The Swedish Armed Forces benefits from the research within the research area Assessment and Operational Research mainly through its planning and decision support function. Research area funding in 2005 totalled 40.1 MSEK, of which 28.9 MSEK covered the Operational Research groups.
