Strategy Formulation for Quality Control in Process Industries
نویسنده
چکیده
Control charting is synonymous with statistical process control (SPC). However, the traditional control chart assumption of data independence is often violated in process industries. This problem has been analyzed and necessary modifications to the widely used SPC tools have been suggested. The performances of the modified estimators and proposed control schemes have also been studied, through simulation. Moreover, since the majority of the actual production systems are multi-stage in nature, various strategies of integrated use of SPC and engineering process control (EPC) tools have been studied through simulation at different correlations, for both the single and two-stage production processes.
