摘要:

基于装备费用敏感性分析较少考虑因子间相互作用及因子概率分布等现状,为在项目研制初期有效识别导弹装备费用驱动因子,全面分析单个因子和因子之间相互作用对于研制费用的影响,在定性分析的基础上,引入基于方差的全局灵敏度分析方法,采用蒙特卡罗随机采样模拟各因子的概率分布,求解费用模型的一阶和全阶灵敏度系数。引用多元二阶导弹费用测算模型,评估灵敏度收敛样本量,测算其输入参数对于费用的全局影响情况,利用测算结果简化模型。通过简化后模型、原模型和任意幂次模型的对比结果,验证基于方差全局灵敏度分析对于导弹装备费用驱动因子识别的有效性。

Abstract:

Based on the current situation of less consideration on the interaction between factors and the probability distribution of factors in the sensitivity analysis of equipment costs, in order to effectively identify the cost driving factors and comprehensively analyze the coupling effect among factors on the missile development cost at the early stage, on the basis of qualitative analysis, a variance-based global sensitivity method is introduced, and Monte Carlo random sampling is used to simulate the probability distribution of each factor to solve the first and the total sensitivity coefficients. Quote one multivariate second-order missile cost model, evalue the sample size of sensitivity convergence, analyze the global impact of inputs on costs, and use the results to simplify this cost model. By comparing the simplified model, the original model and the referenced any power model, the effectiveness of the global sensitivity method for identifying the missile equipment cost driven factor is verified.

Key words: missile equipment, cost driven factor, global sensitivity, sensitivity analysis, sensitivity coefficient
