摘要: 為了提高制造過程質量,預防和減少不合格產品的數量,必須選用高效的控制方法對制造過程進行質量控制,針對當前工序能力指數C_P和C_pk應用不足,難以指導質量問題原因查找和改進方向的缺點,提出了適于現場應用的三個過程能力測度指標C_pa,C_pe和C_pc,用于反映和控制過程質量的分散和偏移,通過具體應用實例,證明了改進指標的適用性。

Abstract: To increase product quality and predict the unqualified products, effective control methods must be selected. Considering the disadvantages of process capability indices C_p and C_pk that are hard to help to find the reason of quality problems and direct quality improvement, three new indices C_ps, C_pc, and C_pc available in real time are introduced to control the scatters and errors. Finally the feasibility of these indices is proved by an application.
