Statistical process control(SPC) and engineering process control(EPC) are two strategies for quality improvement that have developed independently. In general, both techniques have reduction of variability as their objective, although they seek to accomplish these objective in different ways. Integration of SPC and EPC is finding wide recognition and is successfully used in continuous process industries. A simple case of an integral controller is presented here to show the application of MMSE controller to stochastic process. In order to keep the system on target, the actual adjustment in terms of MMSE using integral control can be implemented. This paper demonstrates that SPC, already used for process monitoring in the parts industries, and EPC, now used in process industries, may be integrated in various type industry for more effective control of processes.
