| Summary: | Carta kawalan multivariat ialah alat yang berkuasa dalam kawalan proses yang
melibatkan kawalan serentak beberapa cirian kualiti yang berkorelasi. Carta-carta
multivariat hasil tambah longgokan {MCUSUM) dan multivariat purata bergerak
berpemberat eksponen (MEWMA) sentiasa dicadangkan dalam kawalan proses

A multivariate control chart is a powerful tool in process control involving a
simultaneous monitoring of several correlated quality characteristics. The multivariate
cumulative sum (MCUSUM) and multivariate exponentially weighted moving average
(MEWMA) charts are often recommended in process monitoring when a quick
detection of small or moderate sustained shifts in the mean vector is desired. |
