摘　　要：传统控制图作为统计过程控制(statistical process control,SPC)的核心工具,对影响制造过程的系统性因素识别效率较低。文章针对传统控制图对系统性因素识别不充分的问题,提出基于随机森林的控制图模式识别模型,利用网格搜索法进行参数优化,建立基于随机森林算法流程和控制图模式识别模型以识别影响过程失控的系统性因素;以汽车离合器为例,将基于随机森林的模式识别算法应用到离合器制造过程中,并与支持向量机(support vector machine,SVM)、逻辑回归(logistic regression,LR)等机器学习算法相比较,结果验证了随机森林模型对控制图模式识别的可行性和有效性。As the core tool of statistical process control(SPC),the traditional control chart has limitations in terms of the recognition of systematic factors that affect the manufacturing process.Aiming to solve the problem of insufficient systematic factors recognition of the traditional control chart,this paper proposes a control chart pattern recognition model based on random forest.The grid search method is used to optimize the parameters,and a model based on random forest algorithm flow and control chart pattern recognition is established to identify the systematic factors that affect the process out of control.Taking the automobile clutch as an example,the pattern recognition algorithm based on random forest is applied to the clutch manufacturing process,and then compared with the support vector machine(SVM),logistic regression(LR)and other machine learning methods to verify the feasibility and effectiveness of the random forest model for the control chart pattern recognition.
