针对具有二维平面自然顺序关系的多元数据，提出了一种基于二维Fused LASSO回归模型的多元统计过程控制图。由于二维Fused LASSO多元回归模型对相邻系数的差异进行惩罚，因此它对检测出变量间的自然顺序关系非常有效。通过数值仿真实验可以看到，二维Fused LASSO控制图能更加快速有效地检测出具有二维平面自然顺序的多元过程中均值发生的变化，且在偏移量越大的情况下优势更加明显。最后通过对发动机平面度数据的实例验证，给出了二维Fused LASSO控制图的步骤和适用性。
針對具有二維平麵自然順序關繫的多元數據，提齣瞭一種基于二維Fused LASSO迴歸模型的多元統計過程控製圖。由于二維Fused LASSO多元迴歸模型對相鄰繫數的差異進行懲罰，因此它對檢測齣變量間的自然順序關繫非常有效。通過數值倣真實驗可以看到，二維Fused LASSO控製圖能更加快速有效地檢測齣具有二維平麵自然順序的多元過程中均值髮生的變化，且在偏移量越大的情況下優勢更加明顯。最後通過對髮動機平麵度數據的實例驗證，給齣瞭二維Fused LASSO控製圖的步驟和適用性。

A new multivariate statistical process control ( MSPC) chart methodology is developed based on the two-dimensional Fused LASSO ( least absolute shrinkage and selection operator ) for quality control in which the mean shifts have some natural ordering in two-dimensional plane .Because of the two-dimension-al Fused LASSO penalties on the difference between successive variables , it is a desirable tool to identify the natural ordering among variables .The numeric simulation study shows that the two-dimensional Fused LASSO control chart can more quickly and efficiently detect mean shift of such structure , especially where the shift value is large .Finally an application to the engine flatness data shows that the two-dimensional Fused LASSO control chart is applicable and useful .
