Req: 置信 度 confidence = 95%Once confirmed that the RED X is living in the door panel molding, we decided to change our strategy from “model to model” to “truck to truck” because the door panel molding is unique for Cadillac models. In other words, find one characteristic in the same door panel 805/830 model that makes the difference, because there are some door panels that require almost 20 lbs to pulled out of it position from the door and there are others with less than 10 lbs to pulled out of it position。Frequency頻率GREEN Y RUN CHART SEE PAG 17/綠 Y字流程圖參見第 17頁。PASSED B vs C WHERE IT SHOWS THAT THE DOOR MOLDING KEEP IN POSITION THE DOOR PANEL SEE PAG 10, BUT WE CHOICE OTHER CHARACTERISTIC THAT KEEP IN POSITION THE DOOR PANEL AND WITOUT INVEST MONEY SEE PAG 11 13.通過 BC對比試驗(yàn)，顯示車門飾板飾件能夠使車門飾板保持正確位置，見第 10頁。GOAL: eliminate 100% the poor fit.目標(biāo)： 100%消除不良的配合Project statement項(xiàng)目綜述Need energy to release the trim door panel需要用力才能卸下門飾板Customer is calling the problem in both sides客戶現(xiàn)在對兩側(cè)都在抱怨Effort to release (lbs)/釋放力 (磅 )Frequency頻率 CURRENT現(xiàn)有 DESIRED希望Solution tree項(xiàng)目解決樹TARGET: Eliminate condition 100%目標(biāo)： 100%消除現(xiàn)有問題PASSED ISOPLOT DR= SEE PAG 4通過等量圖驗(yàn)證 DR= 參見第 4頁P(yáng)ASSED STAGE 1 SO THE RED X DOESN’T LIVE IN THE PROCESS SEE PAG 7.通過第一階段驗(yàn)證，因此紅 X不在裝配過程中，參見第 7頁。此項(xiàng)目便是一個(gè)這樣的例子。學(xué)到的經(jīng)驗(yàn) ： 我們學(xué)到了 當(dāng)投資不會(huì)太多的情況下，用其它策略以尋求可選擇的方法解決問題。用 6對數(shù)據(jù)進(jìn)行比較具有 95%的可信度和最大累加值為 6.不可撤銷的糾正措施 ：為使門邊緣加長 。成對比較表明門型是成對比較點(diǎn)。 (DR=, M=, P= 4頁 線索產(chǎn)生 ： 階段 1表明紅 X不在過程中。 (見見第 6頁 )測量系統(tǒng) ：用測力計(jì)作為測量系統(tǒng)。 (805/830型 )項(xiàng)目綜述 ： 針對 Lilao裝配廠 805/830車型的右后門飾板，發(fā)現(xiàn)并解決其配合不好的問題。vez salcedoInitial date: oct042023Final date: oct292023Problem description:This month it was reported by the shipping lot in USA a problem of quality existed in the 805/830 vehicles.
