Using Fuzzy Principal Component Estimate in weapon system Life Cycle Cost modeling

摘要

Life Cycle Cost modeling of weapon system more adopts Parameter method, and Parameter method most frequently uses the Least Squares Estimate. This paper proposes using Fuzzy Principal Component Estimate to set up life cycle cost model of weapon system, and as an example, a Life Cycle Cost model is set up by this method. Result indicates that this method can improve multicollinearity of the Least Squares Estimate, at the same time, it have practical value.
