装备效能仿真试验因子灰色关联筛选方法研究

装备效能仿真试验因子众多且分布各异,这导致仿真试验成本增加。提出了一种基于灰色关联分析的试验因子筛选方法。基于少量仿真试验样本数据,通过计算各试验因子相对于装备效能值的灰色绝对关联度,筛选出较敏感指标,从而实现试验因子空间降维,降低仿真试验成本。以某型防空导弹武器系统作战效能仿真试验因子筛选为例,验证了该方法的可行性。

Research on Factor Selection Method of Equipment Effectiveness Simulation Experiment Based on Grey Correlation Analysis

The large number and different distributions of the equipment effectiveness simulation experiments factors, increase the experiments costs. Aiming at this, a factor screening method based on the grey correlation analysis theory is proposed. On the basis of the small amount of simulation data, the grey absolute correlation degree value relative to the effectiveness value of each factor is calculated, and the more sensitive indexes are screened out, the spatial dimensionality reduction is realized and the experiments costs of simulations are reduced. The feasibility of the method is verified by the factor screening simulation experiments of an air defense missile weapon system.
