if shown control chart patterns, the six sigma black belt should be able to match the control chart with the correct situation ( e . g ., an outlier pattern vs . a gradual trend matched to a tool breaking vs . a machine gradually warming up ) 译文:如果看一份控制图,六西格玛黑带应该能够将控制图与正确的状况匹配(例如,把超出控制限的图案、渐进的趋势与工具损坏、设计越来越热相匹配。)
pattern recognition of abnormal control charts can provide clues to reveal potential quality problems in manufacturing process . it has been a necessary technology to realize the automatic recognition of abnormal patterns with the need of automation and intelligence of pqc . in this paper, a new ann model named regional supervised feature mapping ( rsfm ) network is proposed to recognize the control chart patterns, which include six basic patterns and their mixed patterns 提出了一种新型的神经网络模型??局部有监督特征映射(regionalsupervisedfeaturemapping,rsfm)网络,对网络的收敛性、模式分类和自适应能力等性能进行了理论分析和实验验证,结果表明该网络学习快速,特征提取能力强,自适应能力也较好。
