本篇研究的目的為建立Optimal DS AL管制圖,並以ARL為績效的衡量指標,接著以R軟體的基因演算法決定使失控ARL最小化的管制界線。接著建立DSVSI EWMA AL管制圖,並以ATS為績效的衡量指標。當EWMA的權重 時,DSVSI EWMA AL管制圖則簡化為DSVSI AL管制圖,當固定抽樣間隔時,DSVSI EWMA AL管制圖則簡化為DS EWMA AL管制圖,當EWMA的權重 且抽樣間隔固定時,DSVSI EWMA AL管制圖則簡化為DS AL管制圖。最後以資料分析比較 DSVSI EWMA AL管制圖、DSVSI AL管制圖 、DS EWMA AL管制圖、Optimal DS AL管制圖、 DS AL管制圖 、 Optimal VSI AL管制圖(Yang 2013a) 、AL管制圖(Yang 2013)和DS X-bar and S管制圖(He and Grigoryan 2004)之失控的偵測績效。
