基于EWMA的计算机辅助质量控制系统

A EWMA-based CAQC System

对传统的质量控制算法和常规计算机质量控制算法进行了比较,把它们统一起来,并提出了一个变形了的EWMA质量控制算法,推导验证了其无偏估计量,分别针对抛弃和非抛弃两种形式求出了各自递推表达式。最后设计了一个基于EWMA计算机辅助质量控制系统,并据此进行了实验仿真。

This paper compares the traditional QC Algorithm with that one of convent ional CAQC,while using a same expression to unify them.Then,it brings forward a deformed EWMA-based CAQC algorithm,deduces and verifies its no-deviation estimate,and gives out two recursive expressions with /without the consideratio n of data dump respectively.Finally,an EWMA-based CAQC system is designed and a s imulation experiment is performed.[
