Shewhart Control Charts Implementation for Quality and Production Management

Shewhart control charts are suitable for stable but repetitive production processes used the subsequent identification of random deviations while indicating breached quality limits. They provide information on process variability and, at same time, make it possible to obtain reliability monitored processes. The objective this paper is assess characteristics plastic mouldings needs automotive industry with application method, specifically charts. were applied evaluate characteristics, or, more specifically, measured width and length produced by statistical analysis. Statistical analyses show that set parameters not met in first two days test series. An improvement observed last day well set, as confirmed our verification stability process. important condition setting observe correct chronological arrangement regular acquisition values. Solving tasks future must be oriented an evaluation capability product. proposal research will toward via indices derive continuous data using classical method.
