FUZZY EIGENVALUE METHOD IN LIFE CYCLE COST MODELING OF SHIP EQUIPMENT

摘要

The parameter method is often used in life cycle cost modeling of ship equipment and the least squares regression is frequently adopted in the method. This paper proposes to set up life cycle cost model of ship equipment by the fuzzy eigenvalue method and analyses the life cycle cost with an example. Result indicates that this method can improve multicollinearity of least squares regression, thus having great practical value.
