Modeling Emergency Supply Flexibility in a Two-Echelon Inventory System

Patrik Alfredsson, Jos Verrijdt
1999 Management science  
We consider a two-echelon inventory system for service parts.  ...  To obtain high service levels at a low cost we allow not only for normal supply of parts but also for emergency supply options in terms of lateral transhipments and direct deliveries.  ...  Aggarwal and Moinzadeh [1] conduct a similar policy evaluation study for a two-echelon system where the locals can issue an emergency replenishment when the number of outstanding orders drops below a  ...

Optimal randomized ordering policies for a capacitated two-echelon distribution inventory system

Taher Ahmadi, Masoud Mahootchi, Kumaraswamy Ponnambalam
2018 Computers & industrial engineering  
We propose a new formulation for controlling inventory in a two-echelon distribution system consisting of one warehouse and multiple non-identical retailers.  ...  In such a system, customer demand occurs based on a normal distribution at the retailers and propagates backward through the system.  ...  Sincere thanks to the referees of the paper, whose comments were so constructive and helpful.  ...

Efficient heuristics for two-echelon spare parts inventory systems with an aggregate mean waiting time constraint per local warehouse

Hartanto Wong, Bram Kranenburg, Geert-Jan van Houtum, Dirk Cattrysse
2007 OR spectrum  
Abstract: This paper presents solution procedures for determining close-to-optimal stocking policies in a multi-item two-echelon spare parts inventory system.  ...  The system we consider consists of a central warehouse and a number of local warehouses, and there is a target for the aggregate mean waiting time per local warehouse.  ...  This model considers multi-item inventory systems with which repair and distribution processes are controlled in a two-echelon system, consisting of a central warehouse and a number of local warehouses  ...

Service and cost benefits through clicks-and-mortar integration: Implications for the centralization/decentralization debate

Elliot Bendoly, Doug Blocher, Kurt M. Bretthauer, M.A. Venkataramanan
2007 European Journal of Operational Research  
So, while we will continue to discuss the concepts in terms of a central warehouse and retail store satellite, one can think of other 2-echelon systems with analogous decisions.  ...  We compare the Model 1 and 2 results with results from a simulation of the 2-echelon system in Figure 10 .  ...

A Stochastic Two-Echelon Supply Chain Model for the Petrol Station Replenishment Problem

Kizito Paul Mubiru
2015 Journal of Operations and Supply Chain Management  
In this paper, a new mathematical model is developed to optimize replenishment policies and inventory costs of a two-echelon supply chain system of kerosene product under demand uncertainty.  ...  The replenishment cost, holding cost and shortage costs are combined with demand and inventory positions in order to generate the inventory cost matrix over the echelons.  ...  In related work by Haji R (2011), a two-echelon inventory system is considered consisting of one central warehouse and a number of non-identical retailers.  ...

2018 Management science  
In the special case of no initial retailer inventories, two periods, and identical retailers, a relaxed form of the problem admits a closed form solution with surprising insights.  ...  In this paper we re-visit a long-standing multi-echelon inventory allocation problem from a robust optimization perspective.  ...  solving a two-echelon central warehouse and multiple retailer distribution system problem.  ...

We describe the complete analysis for the most basic multi-echelon production/inventory system: the serial, two-echelon production/inventory system with linear inventory holding and backordering costs.  ...  We will start with a complete analysis of the most basic system: the two-echelon, serial system. From there on, we describe many extensions that have been made.  ...  For a two-echelon, distribution system with a stock-keeping central warehouse, the optimality of basestock policies under the balance assumption and the decomposition result were derived by Federgruen  ...

Inventory models with lateral transshipments: A review

Colin Paterson, Gudrun Kiesmüller, Ruud Teunter, Kevin Glazebrook
2011 European Journal of Operational Research  
Lateral transshipments within an inventory system are stock movements between locations of the same echelon.  ...  These transshipments can be conducted periodically at predetermined points in time to proactively redistribute stock, or they can be used reactively as a method of meeting demand which cannot be satisfied  ...  Two echelon centralized systems In a system with two echelons there are several ways in which stockouts can be satisfied through emergency stock movements.  ...

Optimizing Reorder Intervals for Two-Echelon Distribution Systems with Stochastic Demand

Kevin H. Shang, Zhijie Tao, Sean X. Zhou
2015 Operations Research  
We consider a periodic-review inventory system in which N non-identical retailers replenish from a warehouse, which further replenishes from an outside vendor with ample supply.  ...  Each facility faces Poisson demand and replenishes according to a base-stock policy in a fixed time interval. Fixed costs are incurred for placing an order.  ...  The third author is partially supported by Hong Kong General Research Fund [CUHK-419010] and the Asian Institute of Supply Chains and Logistics at CUHK.  ...
