鱼雷寿命周期费用参数的灰色敏感性分析

The Sensitivity Analysis for Life Cycle Cost Parameters of Torpedo

鱼雷寿命周期费用受多种因素的影响,各因素对寿命周期费用的作用不同,有的作用大,有的作用小。在对鱼雷寿命周期费用建立模型时,需要分析哪些因素是影响寿命周期费用的主要因素,哪些因素是影响寿命周期费用的次要因素,即对寿命周期费用参数进行敏感性分析。利用灰色系统理论的灰色关联度对鱼雷寿命周期费用参数进行敏感性分析,可对这些参数按重要性进行分类,有利于建立模型时对参量的选择。

Life cycle cost of torpedo is affected by many factors. Effects are different for different factors. The actions of some factors are big while others are small. Which factors affect the life cycle cost heavily and which factors affect the life cycle cost softly should be analyzed when the life cycle cost model of torpedo is set up. That is to say, sensitivity of the parameters should be analyzed. Using grey closeness of the grey system theory analyzes the sensitivity of life cycle cost parameters of torpedo can classify the influencing factors with the weightiness. This has goodness for the parameters selecting of life cycle cost modeling.
