Statistical Quality Control On Vitafoam (Whitefoam) Products

ABSTRACT

In this work, the measured quality characteristics of the Vitafoam Whitefoam products were considered to construct control charts that could be used to study the production processes of Vitafoarn Whitefoam products. Statistical quality control technique used in this work is process control. It was carefully observed that both the process variability and the process mean of the five quality characteristics of the Vitafoarn Whitefoam products are relatively slightly stable. But for a more stable process variability arid process mean, the points that fall outside the warning and action limits were discarded and the revised control limits constructed. Since it was concluded that the company operate on a relatively slightly stable quality standard for the product (Vitafoam). Then for a more improved quality, the company should consider operating a quality control chart for vitafoam whitefoam products and some others.
