The paper develops a model to determine the optimal product reliability and production rate that achieves the biggest total integrated profit for an imperfect manufacturing process. The basic assumption of the classical Economic Manufacturing Quantity (EMQ) model is that all manufacturing items...

The paper investigates an EPL (Economic Production Lotsize) model in an imperfect production system in which the production facility may shift from an 'in-control' state to an 'out-of-control' state at any random time. The basic assumption of the classical EPL model is that 100% of produced...
