在許多工業應用中，製程或產品的品質特徵可被用一個反應變數和一個或多個解釋變量之間的特殊關係解釋之，則稱為剖面資料。本研究主要探討在多家供應商中，選擇具有較高製程能力的供應商，其產品製程具有線性剖面資料特性，並且是以單邊製程規格為製程能力標準。我們提出基於抽樣計畫的方法，在此情況下利用允收品質水準(AQL)及最低允收水準(LTPD)，使用生產者風險及消費者風險，比較作業曲線上兩點(AQL,1-α)以及(LTPD,β)，計算出檢定所需的臨界值，作為供應商選擇決策的依據，這些資訊能有效地幫助決策者來處理此類型的供應商選擇問題。

In many industrial applications, process or product quality characteristics is explained by the special relationship between the variables and one or more explanatory variables, it is called profile. This study focused on the number of suppliers, the selection process has a high capacity supplier of product manufacturing process has a linear profile data characteristics, and process specifications are one-sided process capability. We propose a method based on the sampling plan, in this case the use of acceptable quality level (AQL) and lot tolerance percent defective (LTPD), the use of producer risk and consumer risk, to comparing operating characteristics curve (AQL, 1- α) and (LTPD, β), calculated verification required critical value, as supplier selection decisions based on that information can help decision makers to effectively deal with this type of supplier choice.
