非可计算性项目的统计容许性分析

Statistical Permissibility Analysis on Incomputable Project

对于可计算性项目,利用直积法进行统计容许性分析,是常用的一种方法,但是对于非可计算性项目的参数设计噪声因子如何选取,使得能够准确测量出系统的波动情况,或者说系统中分量如何变化才能准确估计出系统的分布情况。本文从理论上说明了对于非可计算性项目的统计容许性分析,田口方法要好于D′Errico提出的方法,并给出了一个实例加以说明。

Direct product is a usual method to do statistical permissibility analysis on incomputable project. However, as for incomputable project, it is hard to choose the parameter factor of design noise to survey the system the undulation situation. That is to say, it is hard to decide how to change the components of the system to better estimate the distributed situation of the system. In this paper, we proves the Taguchi Method outperforms D＇ Errico＇s method for the statistical permissibility analysis of incomputable project, and a practical example is presented to justify the fact.
