     this paper is devoted to the study of determining optimal process mean in two-stage production systems with rework loops. in this paper, we developed an absorbing markov chain model in production systems where all items are inspected for conformance with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is scrapped. if it falls above an upper limit, the item is reworked, so that rework loops are used for reworking process, because the use of rework loops can significantly increase the system throughput and reduce scrap, cost, etc. this flow of material through the production system can be modeled in an absorbing markov chain. we included cycle time of production line in model. also effects of inspection errors are investigated. numerical examples are given to demonstrate the application of the proposed model.
