| Abstract | ||||
| In recent years a series of multivariate control procedures were developed can detecting the variables which are out-of-control. In this paper, one of the most common using and important procedures is discussed, this is the decomposition of T2 procedure (MYT procedure). Multivariate control charts using Hotelling's T2 statistic are popular and easy to use but interpreting their signals can be a problem. Identifying which characteristic or group of characteristic out-of-control when the chart signals often necessitate an examination of the univariate charts for each variable. This research develops the interpretation of the out-of-control signal. This will be maintained by making an application on the fertilizers factory, i.e. ; one of the most important and biggest factory's in the field of fertilizers. It is important to know that this factory has a special department for quality control; in order to maintain International Standardization Organization (ISO). | ||||
