한국형 기동무기체계 양산비 비용추정관계식 개발에 관한 연구

In this paper, we deal with developing a cost estimation relationships (CER) for Korean maneuverable weaponssystems using historical production cost. To develop the CER, we collected the historical data of the production costof four tanks and five armored vehicles. We also analyzed the Required Operational Capability (ROC) of the weaponssystems and chose cost drivers that can compare operational capabilities of the weapons systems We used Forwardselection, Backward selection, Stepwise Regression and R2 selection as the cost drivers which have the greatest influencewith the dependent variables. And we used Principle Component Regression, Robust Regression and WeightedRegression to deal with multicollinearity and outlier among the data to develop a more appropriate CER. As a result,we were able to develop a production cost CER for Korean maneuverable weapons systems that have the lowest costerrors. Thus, this research is meaningful in terms of developing a CER based on Korean original cost data withoutforeign data and these methods will contribute to developing a Korean cost analysis program in the future.
