The Identification of Sensitive Parameters for Life Cycle Cost of Torpedo with Grey Relational Entropy Method

摘要

Which factors influence life cycle cost of torpedo heavily and which factors influence it softly should be analyzed before the life cycle cost model of torpedo is set up. That is to say, the sensitive parameters of life cycle cost should be identified. Using grey relational entropy of the grey system theory identifies the sensitive parameters of torpedo life cycle cost can classify the influencing factors with the weightiness. This has advantage for the parameters selecting of life cycle cost modeling.
