In a process that is under control, by removing all special causes that are noticed until then, the remaining variability would come from common causes. After taking the process under control, the next stage improves the process. The only target for the production is to get the statistically control, and to reduce the variables in the same time. Because as the variables reduce, the cost is going to be less, too.A large variety of Statistical Process Control (SPC) schemes have been developed for quality and productivity improvement since the 1960s. SPC utilizes statistical methods to monitor manufacturing processes with an aim to maintain and improve the product quality while decreasing the variance. Much research has been conducted on the issues of SPC and the resulting developments are readily available in the literature, see surveys of research on SPC by Lowry and Montgomery (1995), Woodall and Montgomery (1999) and Stoumbos et al. (2000). Nevertheless, conventional SPC methods are typically restricted to a single process stage in industrial and service applications. Quality Control (QC) is an important function in factory as it deals with product inspection before the product was shipped to customers. Statistical process control (SPC) is one of the tools widely used in QC to monitor whether the production process is in control through the use of statistical control chart. Many
