中文摘要 | 製程能力指標是用一個指標的數值來衡量製程是否具有製程能力。大部份有關製程能力的研究均假設泄品的品質特性為常態分配,當產品的品質特性為偏態分配的情況時,是一般研究者較為忽略的。在這篇文章裡,吾人提出一個新的製程能力指標來處理偏態母體,同時也舉一個例子來比較新指標與其他現有的指標。比較結果顯示所提出的新指標比其他現有指標能較合理地測出實際的製程能力。最後吾人提出一個新指標的估計式來估算一個製程的製程能力。 |
英文摘要 | Process capability indices (PCIs), whose purpose is to provide a mumerical measure on whether a production process is capable of producting tiems satisfying the quality requirement present by the customers, have received substantial research attention. Most research work, however, have focused on developing and investigating PCIs for normal populations. PCIs for skew populations have been comparatively neglected. In this paper, we consider a new family of capability indices to cover skew populations. The proposed indices are compared with other existing indices. The results show that the new indices are more reasonable that other existing ones in measuring process capability. In addition, we also consider an estimation method to calculate the proposed new indices. |
