Abstract : Quality control plays a vital role in many areas as it contributes to the quality control of the product and upgrade it. And when there are synchronized measurements of the number p of random variables associated with and measured simultaneously; Assuming that these measurements follow the natural society multiple (. Μ) NP, and the control limits have not known; we always need to take the views initial each variable separately. Must determine the influences that are changing the values ​​of variables so that we can not identify a sample of views outside the control limits. And used this sample to determine the control limits, which is a reference that can be used for any new View. This research is based on the application of the method followed (1992) Tracy et-al, which depends on T Hotelling statistic and that a different number of variables of individual views. Also depends on the attempt to apply the same method using the statistical (1988) Tiku, which is characterized by stability and strength compared with the statistical T Hotelling, using the simulation method in a Monte Carlo. We have discussed through this paper how the model can be applied repeatedly until you can get the reference sample, which can be used to examine a sample of the future through two applications on actual data. We also managed through a simulation study of random samples generated from normal distributions of multiple, determine the control limits of the values ​​of p, as well as different sizes for different samples at levels of 0.01 and moral as well as 0.05. As we tried to apply the same method using the statistical Ticao and Blakrishnn (1988), which is characterized by stability and strength compared with the statistical Hutling T Hotelling, we have explained through a simulation study of the stability of this statistic, which we can in future be used to determine control limits for the distributions of multiple may not belong to the distribution of multivariate normal.
