The primary goal with the investigation of applicable models and programs, is the later use of the information in a specification of an simulation environment suitable for systems evaluation of weapons for precision engagment. Secondary is to identify areas where lack of knowlidge or models exist. The report only shows models and programs avialable at FOI today. Some of the tools are out of date, but is described due to the fact that parts may be usefull in the future. The questions to be answered is based upon the critical technologies identified, and the conclusions, derived in wargames conducted earlier in the project.
