Abstract

This paper develops a model of the cost and quality effectiveness of single and multiple 100% inspections and applies that model to management decision making in the foundry. Four specific cost cases are evaluated against a series of potential scenarios of visual inspection error and the number of inspections performed. Conclusions are drawn about the general advisability of multiple 100% inspections. The work illustrates the relative value of improving incoming product quality and improving the effectiveness of the visual inspection operation and finding that overall cost can be reduced equally by either action to a degree. The work also concludes that repetitive sorting of rejected product to find inadvertently rejected good product is counterproductive in both quality and cost.
