Abstract

Kualitas menjadi faktor dasar keputusan konsumen dalam banyak produk dan jasa. Untuk itu diperlukan suatu metode atau teknik statistik yang berguna dalam jaminan kualitas. Salah satu diantaranya dengan melakukan pengendalian kualitas statistik untuk menyelidiki terjadinya pergeseran yang keeil yang mungkin terjadi dalam proses produksi. - Di - sini akan dibahas pengendali multivariat rata-rata bergerak tertimbang secara eksponensial (Multivariate Exponentially Weighted Moving Average — MEWMA) yang merupakan perluasan. dari EWMA Univariat. Dengan spesifikasi konstanta penghalusan dari tabel ARL yang diberikan akan diketahui batas atas pengendali dan seberapa besar pergeseran yang telah terjadi, sehinnga dapat diketahui bahwa proses dalam keadaan terkendali atau tidak. Quality become the elementary factor of consumer decision in a lot of product and service. That's way it needed a statistic method or technique which is useful in quality guarantee. One of among other things by doing statistical quality control to investigate the happening of small friction which possible happened in course of production. Multivariate Exponentially Weighted Moving Average (MEWMA) represent the extension from EWMA Univariat. With the specification of constanta attenuation from tables ARL given will be known the boundary for controller and how big friction which have been happened in order to know that process in a state of in control or not,
