On the in‐process inspection and correction facilities Available to Purchase

Inspection for quality of product is performed mostly at the end of the production line. Therefore, non‐conformance is known at the time it is inspected. One solution is applying in or between process inspection. Moreover, in or between processes the required correction can be performed before parts are manufactured by the subsequent process. Compares two sequences of in‐process inspection and correction facilities. The first is where the correction is made concurrently with the process (reworking). The second involves establishment of a separate correction facility and therefore correction is performed separately(correcting). Uses process, inspection and correction costs as an economical measurement of accepted product for both sequences. On the other hand, an accepted product is not always perfectly on its target value, which will eventually result in loss to the customer. Uses a model of the sum of these costs and loss to determine the best sequence.
