【文章內(nèi)容簡(jiǎn)介】 ? How do the binations (interactions) of factors affect the response?各因素之間的相互作用怎樣影響試驗(yàn)響應(yīng)？ – We can write the equation that answers these questions 可以用以下公式進(jìn)行預(yù)測(cè) Y = f (X1, X2, X3, …, X n) Y (Response) = Distance Xi (Factors) = Club, Ball, Wind Distance=Constant + Club Effect + Ball Effect + Wind Effect + Club*Ball Interaction Effect + Club*Wind Interaction Effect + Ball*Wind Interaction Effect + Club*Ball*Wind Interaction Effect 29 Fractional Factorial Fit Estimated Effects and Coefficients for Distance (coded units) Term Effect Coef StDev Coef T P Constant Clubs Wind Ball Clubs*Wind Clubs*Ball Wind*Ball Clubs*Wind*Ball Analysis of Variance for Distance (coded units) Source DF Seq SS Adj SS Adj MS F P Main Effects 3 2Way Interactions 3 3Way Interactions 1 Residual Error 8 Pure Error 8 Total 15 Distance= + *Clubs + *Ball + *Wind + *(Club*Ball) + *(Club*Wind) *(Ball*Wind ) + * (Club*Ball*Wind ) 30 Fractional Factorial Fit Estimated Effects and Coefficients for Distance (coded units) Term Effect Coef StDev Coef T P Constant Clubs Wind Ball Clubs*Wind Clubs*Ball Wind*Ball Clubs*Wind*Ball Analysis of Variance for Distance (coded units) Source DF Seq SS Adj SS Adj MS F P Main Effects 3 2Way Interactions 3 3Way Interactions 1 Residual Error 8 Pure Error 8 Total 15 由于只有 Clubs, Wind, Balls 的 Main Effect 和 Clubs*Wind, Wind*Ball 的 Interaction Effect is Significant (p ) Distance= + *Clubs + *Ball + *Wind + *(Club*Wind) *(Ball*Wind ) 31 球棒 , 球和風(fēng)以及球棒 *風(fēng) , 球 *風(fēng)之間的相互作用 對(duì)提高成績(jī)有顯著影響 Distance= + *Clubs + *Ball + *Wind + *(Club*Wind) *(Ball*Wind ) Distance Max = + + + + = 為得到最佳成績(jī)， 必須使用 Callaway球棒、 Titliest球在有風(fēng)的場(chǎng)地上練習(xí) Key 1 Callaway 1 Ping 1 Windy 1 No wind 1 Pinnacle 1 Titliest 試驗(yàn)結(jié)論 32 試驗(yàn)策略 ?重復(fù) (Replication) : 以隨機(jī)的次序把整個(gè)試驗(yàn)重做一次，而不是按同樣的次序把試驗(yàn)再做一次。 ?隨機(jī)化 (Randomization): 以一種無(wú)固定模式的次序來(lái)做試驗(yàn)。 試驗(yàn)需考慮的 2個(gè)原則： 重復(fù) (Replication) 和 隨機(jī)化 (Randomization) : 試驗(yàn)設(shè)計(jì) (DOE)的 Ramp。R 33 有效試驗(yàn)的障礙 問(wèn)題不清楚 試驗(yàn)?zāi)康牟磺宄? 不理解 DOE的策略和工具 試驗(yàn)結(jié)果不清楚 DOE 成本太高 DOE 浪費(fèi)時(shí)間 我們需要即時(shí)的結(jié)果 不理解 DOE的好處 對(duì) DOE缺乏信心 34 DOE 試驗(yàn) Customers of CHI (Cellulose Helicopters Inc.) have been plaining about the limited flight time of CHI helicopters. 公司的客戶 CHI 抱怨 公司直升機(jī) 的 巡航 飛行時(shí)間 太短 Management wants to increase flight time to improve customer satisfaction. 公司 決定 通過(guò) 提高直升機(jī)的 巡航飛行時(shí)間 來(lái)提高 客戶 滿意度 。 You are put in charge of this improvement project. 你 將 負(fù)責(zé)該項(xiàng)目 How would you approach this problem? 你將 怎樣 來(lái) 解決 這 個(gè) 問(wèn)題 呢 ？ 35 The Standard Design 直升機(jī)的標(biāo)準(zhǔn)設(shè)置 別針處 Factor因子 Standard標(biāo)準(zhǔn) () Paper Clip 別針 無(wú) Wing Width 機(jī)翼寬度 寬 Body Le
