在模型构造中，采用小波概率神经网络进行控制图的模式识别和控制图异常模式的参数估计。
In the modeling of the structure, the wavelet probabilistic neural network was used to recognize the control chart patterns and estimate the abnormal patterns parameters.
其次，基于BP神经网络，对控制图的模式识别问题进行了研究。
Secondly, pattern recognition for control chart is researched based on the BP neural network.
