Analysis of an inventory system under supply uncertainty
Gullu, R; Onol, E; Erkip, N (Elsevier BV, 1999-03-20)
In this paper, we analyze a periodic review, single-item inventory model under supply uncertainty. The objective is to minimize expected holding and backorder costs over a finite planning horizon under the supply constraints. The uncertainty in supply is modeled using a three-point probability mass function. The supply is either completely available, partially available, or the supply is unavailable. Machine breakdowns, shortages in the capacity of the supplier, strikes, etc., are possible causes of uncerta...
Analysis of a deterministic demand production/inventory system under nonstationary supply uncertainty
Gullu, R; Onol, E; Erkip, N (Informa UK Limited, 1997-08-01)
In this article we investigate a periodic review inventory model under deterministic dynamic demand and supply unavailability. In a given period, supply is either available or completely unavailable with given probabilities. Supply unavailability probabilities are nonstationary over time. We show the optimality of an order-up-to level policy, and obtain a newsboy-like formula that determines the optimal order-up-to levels. Our formula would provide guidence as to the appropriate amount of inventory to stock...

Analysis of an inventory system with advance emand information and supply uncertainty
Arıkan, Emel; Süral, Haldun; Department of Industrial Engineering (2005)
In this study we address a periodic review capacitated inventory system with supply uncertainty where advance demand information is available. A stochastic dynamic programming formulation is applied with the objective of minimizing the expected inventory related costs over a finite horizon. Three different supply processes are assumed. Under the all-or-nothing type supply process and partially available supply process, the structure of optimal policy is proved to be a base stock policy and numerical example...
Analysis of serial inventory systems under nonstationary demand
Baskan, Fevzi; Güllü, Refik; Department of Industrial Engineering (2004)
In this study we consider a two-echelon supply chain with a nonstationary demand process. The retailer batches the customer demand for a predetermined number of periods before placing an order to the supplier. We show that the demand process for the supplier is more variable than that for the retailer. It is observed that the supplier can reduce the variability of orders by tracking the exogenous demand occurring at the retailer's side.
