    Abstract: 製程良率常用來評估製程能力好壞的衡量標準,Boyles(1994)提出在常態製程下之Spu, Spl和Spk指標,並說明Spk和製程良率有一對一的函數關係。然而在非常態下,Spk公式有重新檢討的必要,本文藉由Chen(2000)所提出之不受限常態製程下之S''''pu, S''''pl和S''''pk指標,利用無母數Burr分配的架構,找出S''''pu, S''''pl和''''Spk的估計式,並在常態及各種非常態製程分配下,以均方差來評估S''''pu, S''''pl和Spk估計式的準確性。最後,模擬結果證實本研究所提出之估計式能夠在各種常態與非常態下準確的評估製程的良率。
