MULTITYPE REWORK IN 2-STAGE PRODUCTION SYSTEMS - EXPECTED OUTPUT

This paper deals with the analysis of a two-stage production system. It provides an integrated framework to consider manufacturing, inspection and rework activities simultaneously. Rework of a defective item produced by machine I is done on machine I itself and depends on the type of defect. Explicit expressions for some of the system characteristics have been obtained using the state-space method and regeneration point technique. All the random variables involved in the analysis are assumed to be arbitrarily distributed (i.e., general) except for the arrival time distribution of input to the system.
