Track: Quality
Abstract
In this research, some of the statistical process control techniques were applied on a real case study of industry to reduce the product defective ratio. The company was suffering from the absence of supervision for quality control measurements and monitoring the process, which increased the variability, where the number of defective bags increased with time without taking action. The average loss of material was around $330, which is not accepted by the quality managers. The control charts showed that most of the defects in bags occur in the bag length with a percentage of 56%. Pareto diagram presented the mismatching of triangular pockets, hole perforation and overlapping to be most frequent defective bags.
