We consider a multistage inventory system composed of a single warehouse that receives a single product from a single supplier and replenishes the inventory of n retailers through direct shipments. Ordering costs are dominated by the shipping costs associated with full truckload transportation with cargo capacity constraints. All costs are stationary. Demands for the n retailers over a planning...

This study investigates a two-echelon supply chain model for deteriorating inventory in which the retailer’s warehouse has a limited capacity. The system includes one wholesaler and one retailer and aims to minimise the total cost. The demand rate in retailer is stock-dependent and in case of any shortages, the demand is partially backlogged. The warehouse capacity in the retailer (OW) is limit...

This paper considers the so called warehouse problem with both space and injection/withdrawal capacity limits. This is a foundational problem in the merchant management of assets for the storage of commodities, such as energy sources and natural resources. When the commodity spot price evolves according to an exogenous Markov process, this work shows that the optimal inventory trading policy of...

The data warehousing is becoming increasingly important in terms of strategic decision making through their capacity to integrate heterogeneous data from multiple information sources in a common storage space, for querying and analysis. So it can evolve into a multi-tier structure where parts of the organization take information from the main data warehouse into their own systems. These may inc...

This study examines the effect of monetary inflation for a two-warehouse single-product inventory system, in which items are stored limited capacity Own Warehouse (OW) and an unlimited Rental (RW). Demand item is considered stock dependent. Items may deteriorate at different constant rate both warehouses. Shortages allowed stock-out period partially backlogged satisfied next replenishment point...

The problem that we consider here deals with a single vehicle of a given capacity that needs to serve N customers: some of the customers require a delivery of stock from the warehouse, whereas others need to deliver stock from their location to the warehouse. The objective is to find a shortest feasible tour visiting all customers, emanating from and ending at the warehouse. We introduce an eff...

This model considers a two-warehouse inventory system of deteriorated items with ramp-type demand and constant rate deterioration. It is maintained rental warehouse (RW) infinite capacity to load the excess replenished goods after filling finite in own (OW). Retailers are encouraged opt for prepayment option paying their purchase cost equal installments prior delivery ordered considerable disco...

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...
