Strategic Safety Stock Placement In Supply Chains
We consider a multi-stage production/distribution supply chain subject to stochastic demand. We formulate an optimization problem to determine where to place decoupling inventories, so-called strategic inventories, across the supply chain so as to minimize inventory holding costs subject to a service constraint for satisfying customer demand. We assume demand is normally distributed. For each s...
متن کاملCorrespondence: Erratum: Optimizing Strategic Safety Stock Placement in Supply Chains
In Graves Willems (2000) we consider the problem of finding the optimal placement of safety stocks in a supply chain with bounded demand and guaranteed service times. We develop a dynamic programming algorithm for supply chains that can be modeled as spanning trees. The intent of this note is to correct an error in the algorithm. Ekaterina Lesnaia of MIT and Dr. Salal Humair of Optiant independ...
متن کاملOptimizing Strategic Safety Stock Placement in Supply Chains
Manufacturing managers face increasing pressure to reduce inventories across the supply chain. However, in complex supply chains, it is not always obviouswhere to hold safety stock to minimize inventory costs and provide a high level of service to the final customer. In this paper we develop a framework for modeling strategic safety stock in a supply chain that is subject to demand or forecast ...
متن کاملSafety Stock Positioning in Supply Chains with Stochastic Lead Times
W study the safety stock positioning problem in single-product multistage supply chains with tree network structures, where each stage controls its inventory using an installation continuous-time base-stock policy. External demands follow independent Poisson processes, and unsatisfied demands at each stage are fully backordered. The processing (e.g., production) cycle times and transportation l...
متن کاملPurchase Contract Management with Demand Forecast Updates
We study a two-stage purchase contract with a demand forecast update. The purchase contract provides the buyer an opportunity to adjust an initial commitment based on an updated demand forecast obtained at a later stage. An adjustment, if any, incurs a fixed as well as a variable cost. Using a dynamic programming formulation, we obtain optimal solutions for a class of demand distributions. We a...
