Examining Operational Effects of Imperfect Quality
Regarding quality, manufacturing processes are often considered to be "in control", meaning that the quality is not perfect but within acceptable level. Part of imperfect quality is the formation of defective items, which are formed in random manners. In manufacturing processes with assemblies, certain number of each component is required in each assembly, but due to imperfect quality, the numbers of components' units may not match. Quality is often improved by inspections, which add more randomness due to errors. This presentation is of a preliminary examination of operational effects of imperfect quality, including demonstrations of the significance of these effects.
