This paper considers a two-echelon capacitated supply chain with two non-identical retailers and information sharing. We characterize the optimal inventory policies. We also study the benefits of the optimal stock rationing policy over the first come first served (FCFS) and the modified echelon-stock rationing (MESR) policies. © 2006 Elsevier B.V.

• Two-echelon vehicle routing problem with three important real-world extensions. Simultaneous handling of reverse flows, satellite capacities, and timing aspects. Matheuristic solution approach combines different decomposition strategies. New for efficient feasibility testing local-search moves. Last-mile collection delivery services often rely on multi-echelon logistic systems many types prac...

In multi-echelon inventory systems the performance of a given node is affected by events that occur at many other nodes and in many other time periods. For example, a supply disruption upstream will have an effect on downstream, customer-facing nodes several periods later as the disruption "cascades" through the system. There is very little research on stock-out prediction in single-echelon sys...

With the increasing complexities in supply chains and increasing global trade, integrated supply chain network design is utilized by the firms in order to reduce the overall cost while meeting the customer demand with requisite levels of service. This view of collaborative approach towards supply chain design has the potential of providing competitive edge for the firms in a highly competitive ...

Multi-echelon distribution schemes are one of the most common strategies adopted by the transport companies in an aim of cost reduction, but their identification in scientific literature is not always easy due to a lack of unification. This paper presents the main concepts of two-echelon distribution via a systematic review, in the specific a meta-narrative analysis, in order to identify and un...

We study a class of two echelon, serial systems with identical ordering capacities or limits for both echelons. For the case where the lead time to the upstream echelon is one period, the optimality of state-dependent, modified echelon base-stock policies is proved using a decomposition approach. For the case where the upstream lead time is two periods, we introduce a new class of policies call...

Trade credit is a crucial source of capital particularly for small businesses with limited financing opportunities. Inventory models considering trade have been widely studied. However, while there extensive research on the single-vendor single-buyer inventory model allowing delays in payments, systems where vendor supplies to more than one buyer received less attention. In this paper, we analy...
