Radyo frekanslı tanımlama teknolojisinin tedarik zinciri üzerindeki etkilerinin analizi ve modellenmesi

It is known that inaccurate inventory records can lead to profit losses in a supply chain.Inventory records may not be correct due to various reasons such as transaction errors,misplacement, shrinkage, etc. Companies invest in information technologies to better man-age their inventories. In order to eliminate the inventory inaccuracy and its reasons byincreasing visibility, new technologies such as Radio Frequency Identification (RFID) canbe used.In this thesis, we consider a supply chain consisting of a retailer (distributor) and a sup-plier. We assume a single-period newsvendor-type setting where the retailer purchases theitems from the supplier and distributes them to her regional warehouses. The thesis focuseson the problem of finding the optimal investment levels that maximize profit by decreasinginventory inaccuracy. The optimal level of investment is examined both for the centralizedand the decentralized systems under two scenarios: inventory sharing between the ware-houses is allowed and not allowed. The coordination problem is also considered for bothscenarios. Finally, several extensions of the model are considered: asymmetric warehouseparameters, demand and inventory inaccuracy correlation, imperfect RFID implementationand multiple products.iii
