In-Process Manufacturing Quality Control.
Abstract
The thesis developes a methodology for designing plans for the allocation of in-process inspection effort. The focus of the thesis is on constructing operating rules for the allocation of inspection effort along a production line in which inspection and repair are integral parts of that line. The essential feature of such operating rules is their adaptability, i.e., their capacity to detect and respond to changes in the quality levels at various parts of the manufacturing process. The basic methodology is an application of micro-economic analysis to the production process. The major features restricting the problem setting needed for the proposed methodology to be applicalbe are the following: (1) discrete production units and production sub-processes; (2) identifiability of a finite set of independent attribute defects (or surrogate defects); (3) no information available to monitor the current state of the production process by any means other than inspection of the product; (4) nondestructive inspection, and (5) repairable defects.
