this study deals with a two-level supply chain consisting of one manufacturer and one retailer. we consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. the retailer receives product and conducts a 100% inspection....

A real economic growth only comes from increasing quality and quantity of the factors of production. Most production systems produce items which are of imperfect quality. In a production/inventory situation items which are received or produced are not of perfect quality. Thus the presence of defects which is inevitable in a produced/ordered lot is sorted out by the process of screening. Handlin...

EPQ model; Replenishment lot size; Multiple deliveries; Random defective items; Production; Rework; Scrap items. Abstract This paper derives the optimal replenishment lot size and shipment policy for an Economic Production Quantity (EPQ) model with multiple deliveries and rework of random defective items. The classic EPQmodel assumes a continuous inventory issuing policy for satisfying demand a...

We consider an optimization problem for a multiclass queueing model of a decentralized production-distribution system: A single server can produce a variety of products, and completed units pass through an infinite server delay node on their way to a warehouse inventory. Each product has its own warehouse, demand for each product is satisfied by its associated inventory, and unsatisfied demand ...

One of the celebrated extensions of the economic order/production quantity (EOQ/EPQ) model is one that assumes a received shipment contains a fraction of imperfect (non-conforming) quality items, where these items, detected by 100% screening, are sold as a single batch at a discounted price. This paper revisits this model (Salameh and Jaber, 2000, Int. J. Prod. Econ. 64 (1), 59–64) and extends ...

The production system is unreliable, therefore, prone to random failures directly affecting the products quality. machine status affected by variation and its use over time. In this work a new maintenance strategy with corrective, imperfect perfect employed when process respectively in control, surveillance, critical stages. We increase reliability of subsequent reduction non-conformal items. S...
