We consider a periodic-review inventory system with one warehouse and N non-identical retailers. Each location replenishes inventory according to a base-stock policy in a fixed time interval. A fixed cost is incurred for each inventory reorder. The warehouse fills the retailers’ orders in the same sequence as the original demand. The objective is to minimize the long-run average system cost per...

We consider a distribution system with a central warehouse and multiple retailers. The warehouse orders from an outside supplier and replenishes the retailers which in turn satisfy customer demand. The retailers are nonidentical, and their demand processes are independent compound Poisson. There are economies of scale in inventory replenishment, which is controlled by an echelon-stock, batch-tr...

In this paper, we consider a dual-channel vendor-buyer system consisting of a buyer and two vendor-owned facilities: a central distribution center (DC) and a regional DC. Orders for a single item are delivered through two distinct channels: an indirect channel, comprising the central DC, the regional DC and the buyer; and a direct channel, comprising the central DC and the buyer, bypassing the ...

This paper considers a single-item, two-echelon, continuous-review inventory model. A number of retailers have their stock replenished from a central warehouse. The warehouse in turn replenishes stock from an external supplier. The demand processes on the retailers are independent Poisson. Demand not met at a retailer is lost. The order quantity from each retailer on the warehouse and from the ...
