Portfolioanalyysi asejärjestelmien kustannustehokkuuden arvioinnissa

Cost-ectiveness evaluation of weapon systems is needed to support acquisition planning of new systems to produce well-grounded allocation of resources to achieve the impact requirements. Evaluation of cost-ectiveness is often complicated by presence of multiple impact criteria, which may depend on other systems used and the operating situation. The cost-ectiveness analysis of weapon systems supports producing recommendations on how resources should be allocated between the acquisition of new systems and the service and maintenance of previously acquired systems. This thesis develops methodologies based on portfolio and scenario analysis for the coste ctiveness evaluation of weapon systems to support acquisition planning. The coste ctiveness of weapon system combinations (i.e. portfolios) is evaluated at dirent budget levels with regard to several impact criteria in multiple scenarios. The information about the impacts of weapon systems is captured from an independent battle simulator, which allows taking into account the interdependencies among weapon systems. The developed methodology admits incomplete information on the evaluation data and also multiple interpretations of impact criteria's importance in dirent scenarios. The developed methodology is applied in the cost-ectiveness evaluation of artillery systems, where impact data is captured from Sandis -battle simulator developed by Finnish Defense Forces
