  3. Abstract:
  4. In this paper we consider a single stage production system in which defective items are produced in each cycle of production. In the litrature of inventory control when the rework is done on defective items it is assumed that the storage space is unlimited and the setup time for rework is ignored. Here we assume that the storage space is limited and due to the nature of the rework process its production rate is different from the normal production rate. We also assume that after each production run the rework process starts immediately after a non-zero setup time for the rework. Further we assume that the unit operation processing cost during the normal production and rework proccessing times are different. For this system, we derive the total cost function, consisting of inventory holding, setup, normal production process, and rework process costs per unit time. Then we obtain the economic batch quantity (EBQ) which minimizes this expected total cost. and satisfies the storage space constraint. Copyright©(2008) by Computers & Industrial Engineering
