This study is designed to show the applicability of Value Added Analysis (VAA) as a multi-criteria decision analysis tool for deriving consensus among three branches of military experts about building military force. Two phased VAA model is developed to identify essential combat functions and specific weapon systems. The phase I is designed to estimate the implicit effectiveness coefficients using AHP and TOPSIS. The phase II is to evaluate the coefficients of explicit effectiveness of weapon systems by analyzing the interaction effect of combat systems. The proposed VAA model is applied to two types of Korean Force Planning scenario in light of the future security environment. Phase I of our model decides the priority of resource allocation among three branches of military services. The evaluation process of Phase I is composed of three level hierarchies. The first hierarchy applies AHP to decide the priority of resource allocation in meeting the strategic goal. The second employs TOPSIS to calculate the relative importance of each essential combat function. The third assesses the cost and performance of a specific weapon system. One of the significant refinements of this thesis is to verify the validity of G-value as a judgment rule of consistency checking in applying AHP to the force planning. The other refinement is to show the applicability of TOPSIS technique in weighting the multi-criteria ($n>7$) decision problems.
