同类异型产品环境因子的确定方法及应用

Determination Method of Environmental Factors for Same Kind Products and Its Application

把同类异型产品在不同试验条件下的试验数据作为一个整体,提出了同类异型产品环境因子的2种确定方法,推导了极大似然估计和利用混合泊松分布模型的矩估计环境因子估计公式。通过数值仿真对所提方法进行了验证,分析了环境因子估计方法的精度。最后,将该方法应用于火炮火力系统的环境因子估算中,结果合理。

The experiment data of same kind products under different test environments were considered as an integrated whole.On the basis of this,two methods used for environmental factors determination were put forward,and the formulae to evaluate environmental factors were established on basis of the maximum likelihood estimation and the moment estimation of mixed Poisson random variables.The accuracy of environmental factors determined by the two methods was analyzed by numerical simulation.Finally,the methods established were applied to evaluate the environmental factors in cannon fire system,and reasonable results were obtained.
