摘要
介绍了鱼雷寿命周期费用的概念和研究寿命周期费用的重要性,并对影响寿命周期费用的敏感参量进行识别。影响鱼雷寿命周期费用的参量很多,各参量对寿命周期费用的作用不完全相同,影响大的参量是鱼雷寿命周期费用的敏感参量。信息论中的相对熵可用于度量两个参量符合的程度,符合的程度越大,相对熵越小。结合实例对鱼雷寿命周期费用的敏感参量进行了识别,结果令人满意。利用相对熵理论识别鱼雷寿命周期费用模型敏感参量,对影响寿命周期费用的因素按重要性进行分类,便于建立模型时对参量的选择。
This article introduces the conception of life cycle cost for torpedo and the importance of studying life cycle cost, and then identifies the sensitive parameters of the life cycle cost. Life cycle cost of torpedo is affected by many factors. Effects are different for different parameters. The parameters, which have big effects, are the sensitive parameters. The relative entropy of information theory can be used to measure the consistent degree of two parameters. The greater the consistent degree is, the smaller the relative entropy. Using the relative entropy to identify the sensitive parameters of torpedo life cycle cost can classify the influencing factors with the weightiness, which is convenient for the selection of the life cycle cost model parameters.
