INTEGRATED IMPERFECT PRODUCTION INVENTORY MODEL UNDERPERMISSIBLE DELAY IN PAYMENTWITHSYNCHORNISED UNEQUAL-SIZE BATCH DELIVERY POLICY

Abstract
Abstract - A integrated inventory model reduced the cost between vendor and buyer, improving the efficiency of whole supply chain. In this paper, we present a multi-vendor multi-buyer for a single product mathematical model that the production process is imperfect and it will be inspected when the vendor receives the products. To make the model closer to the reality, we consider the vendor offers permissible delay in payment for the buyer in JIT system. Furthermore, the order from each buyer was divided into a number of unequal-size batches shipment. We aim to get the minimize joint total cost obtain by the optimal decision, applying some numerical examples to illustrate the effect of the model.
