SEE PAG 7./零部件分析階段 2顯示紅 X不是由車門內飾板造成的 ,所以應是由車門板的其余部分引起的 ,見 7頁 . PAIR COMPARISON SHOWS THAT THE DOOR PANEL MOLDING HAS THE CHARACTERISTIC THAT PRODUCE THE DIFFERENCE SEE PAG 9/ 配對對比顯示車門飾板飾件有造成差異的特征 , 參見第 9頁 THIS IS THE BEST STRATEGY BASED ON MULTIVARI SEE PAG 5.這是基于多重變換比較得出的最佳策略 , 參見第 5頁 。 Frequency頻率 GREEN Y RUN CHART SEE PAG 17/綠 Y字流程圖參見第 17頁 。 R3 (Door Panel)Seal WindowDoor PanelMolding door panelHomeBOB WOW STAGE 1 STAGE 2 第一階段 第二階段 最好 最壞 原狀態(tài) 第一次拆裝 第二次拆裝 第三次拆裝 門窗密封條 門飾板 門飾板飾條 鉸鏈 注 :這個圖顯示因為通過了第一階段的試驗 ,所以 RED X不是由操作造成 . 第二階段的試驗顯示門窗密封條不是 RED X,門飾板飾條是 RED X 要素查找 規(guī)則 Rule 1.
