摘要

The issue of food safety in modern life has become a worldwide concern. Edible oil is essential for the human body and many types of food processing. The selection of the raw material suppliers in order to control the quality of a oil's final product is very critical. Therefore, a good decision procedure for evaluating the supplier capability is essential. The capability of each supplier can be evaluated from its raw material. The information extracted from samples can be used to calculate a process capability index for estimating the supplier's capabilities. In this paper, the process capability index C_(pu)^T for a product with multiple independent characteristics is employed to deal with a group supplier selection problem. A procedure to compare multiple suppliers is proposed. Comparisons of the proposed method between division and multiple comparisons with the best methods are also provided. Some numerical results for decision making are also presented. Finally, an illustration example based on peanut oil with specifications for levels of heavy metal content is shown.

現代生活中的食品安全問題已成為全世界關注的問題。食用油對於人體和許多類型的食品加工是必不可少的。為了控制油的最終產品的質量，選擇原料供應商是非常關鍵的。因此，用於評估供應商能力的良好決定程序是至關重要的。每個供應商的能力可以從其原材料進行評估。從樣品中提取的信息可被用來計算製程能力指數，用於估計供應商的能力。在本文中，使用具有多個獨立特性的產品的製程能力指數C_(pu)^T來處理集體供應商選擇問題。提出了比較多個供應商的程序。還提供了除法和多重比較之間提出的方法的比較。並提出了一些決策的數值結果。最後，提出了一種基於規範的重金屬含量級別的花生油例證實例。
