基于Sobol指数法作战能力全局敏感性分析方法

本文采用的Sobol指数法,将模型分解为单个参数及参数之间相互组合的函数,通过计算单个输入参数或输入参数集的方差对总输出方差的影响来分析参数的重要性以及参数之间的交互效应。并将Sobol指数法应用于一定作战条件下的鱼雷作战能力分析,探讨了相关关键技术指标及其交互作用对鱼雷作战能力的影响,为鱼雷武器的论证工作提供依据和参考。

Global Sensitivity Analysis Method Based on Sobol Index Method

The Sobol index method is used to decompose the model into a function of single parameter and its mutual combination, and the importance of the parameters and the interaction effect between the parameters and the parameters is analyzed by calculating the impact of variance of input parameter. The Sobol index method is applied to the analysis of torpedo operational capability under certain operational conditions, and the influence of the key technical indexes and their interaction on the operational capability is discussed which provides the basis and reference for the demonstration of torpedo weapon.
