One important aspect of inventory management in supply chains is to determine the optimal quantities of stock that should be placed at different stages of the supply chain so as to minimize the costs of inventory and stockouts. This problem is complex due to the presence of multiple interrelationships among materials held at different inventory stockpiles and numerous sources of uncertainty that affect supply chain performance. This dissertation investigates the single-period inventory placement problem for a serial supply chain subject to stochastic demand. In our model, the stock stored at the upstream stages in the series is used to resupply the lowest stage in case of a shortage. Using the assumption of partial backorder/lost sales, the inventory placement problem is formulated under two alternative objectives. In the first formulation, the problem is to select the stock quantities that should be placed in different stages of the supply chain to minimize the total expected system cost. Under the second objective, one selects the stock quantities to maximize the probability of achieving a budgeted profit level. For each formulation of the model, we discuss the properties of the optimal solution and provide an iterative procedure for solving the problem. The major contributions of this dissertation are twofold. First, this dissertation extends the classic single-period, single-stage inventory problem to the situation where the product can be stored in a multi-stage supply chain. We demonstrate that our formulation, which allows the product to be stored in its various forms, and at various distances from the customer, leads to the reduction of the total cost of inventories and stockouts. Second, this dissertation contributes to the current research in supply chain management by offering two alternative formulations of the inventory placement problem and effective algorithms for obtaining their solutions. These models can help managers improve the performance of their supply chains in a number of industries. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
