This paper explores the application of constrained clustering algorithms to inventory grouping based problems. Our research in this area is based upon a segmentation methodology that considers operationally relevant part attributes. In this paper, we present a brief review of literature on multi-echelon inventory models, and clustering applications to inventory segmentation. Finally, we discuss...

Multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. In this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. We have assumed the demand i...

inventory control is one of the most important issues in supply chain management. in this paper, a three-echelon production, distribution, inventory system composed of one producer, a set of wholesalers and retailers is considered. costumers' demands can be approximated by a normal distribution and the inventory policy is a kind of continuous review (r, q). in this paper, a model based on ...

Materials are often ordered in batches at fixed time intervals in supply chains. We model such a periodic batch-ordering practice as echelon (r, nQ, T ) policies. In addition to linear holding and backorder costs, we consider two types of fixed costs, setup and order costs. The former is incurred for each batch Q ordered; the latter is associated with each reorder interval T . The objective is ...

In this paper, a supplier-retailer transportation system is investigated as a two-echelon environment. There is a single location in each echelon; the unique supplier at the first echelon has to replenish the retailer's warehouse at the second echelon. By the way, the shortage situation should be avoided. For this situation, a model is provided based on the traditional EOQ model. The inventory ...

NATO war medical doctrine was applied in the war in Croatia, Bosnia and Herzegovina. However, due to rather specific martial and organizational circumstances, the doctrine had to be modified. sometimes substantially. A medical team from the war hospital in Livno, Bosnia and Herzegovina describes their work with respect to the four-echelon NATO doctrine. The team covered a relatively large and a...

Joint managed inventory is an advanced supply chain inventory management tool, which will effectively tackle the complicated problem between the inventory cost of supply chain and service level. The research on inventory model and its’ control under JMI environment is a hot issue at present. In this paper, the authors deeply discuss the question of the inventory time costs about the multi-produ...

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.
