Multi-echelon inventory modeling and supply redesign
… and finished goods through the supply chain of a multi-national oilfield services company. We study a centralized inventory approach, assessed through heuristics, against the existing decentralized approach. Sensitivity analysis with regard to service level, and mode of transport strengthened the …

A new perspective on multi-echelon inventory systems
We present a new methodology for analyzing multi-echelon inventory systems. The methodology relies on decomposing complicated multi-echelon inventory control problems into much smaller and managable subproblems, whose solutions in turn help us either characterize the structure of optimal policies …

Inventory optimization in a retail multi-echelon environment
… optimal inventory distribution in a retail three-echelon environment, consisting of a supplier, a DC, and stores. An inventory model is built by replicating the echelons' periodic, order-up-to-level policies with all echelons' transactions integrated. Network carrying cost is set as an objective …

Multi-echelon inventory management for a fresh produce retail supply chain
… and lower service levels. If a supply chain has multiple echelons, that further complicates the issue since companies have an added risk of not having the right amount of product at the right location at the right time. We conduct our research on Chiquita's Fresh Express supply chain. We analyze …
