The bi-objective warehouse problem in a crisp environment is often not eective in dealing with the imprecision or vagueness in the values of the problem parameters. To deal with such situations, several researchers have proposed that the parameters be represented as fuzzy numbers. We describe a new algorithm for fuzzy bi-objective warehouse problem using a ranking function followed by an applic...

In this research work, a wholesaler-retailer-customer supply chain model for a deteriorating item is considered, where the retailer's warehouse in the market place has a limited capacity. The retailer can rent an additional warehouse (rented warehouse) if needed, with a higher rent compared to the existing warehouse (own warehouse). The customers' demand of the item is linearly influenced by th...

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

Data warehouse is the powerful tool in telecommunications industry for handling the massive amounts of data. It assists telecommunication companies in achieving a competitive advantage and higher profits. Theaim of this paper is to focus on data warehousing in telecommunication companies and why they need advanced data warehouse platforms and new technology. It compares traditional data warehou...

We develop a decision support system, based on the data warehousing approach. We define a conceptual object-oriented data warehouse model, which describes the data warehouse as a central repository of relevant, complex and temporal data. Our model integrates three concepts: warehouse object, environment and warehouse class. Each warehouse object representing a source entity, is composed of one ...

This paper deals with an i * Corresponding author Email address:   nventory system with one central warehouse and a number of identical retailers. We consider perishable-on-the-shelf items; that is, all items have a fixed shelf life and start to age on their arrival at the retailers. Each retailer faces Poisson demand and employs (1, T) inventory policy. Although demand not met at a retai...

In this paper, we study the data warehouse modelling used in decision support systems. We provide an objectoriented data warehouse model allowing data warehouse description as a central repository of relevant, complex and temporal data. Our model integrates three concepts such as warehouse object, environment and warehouse class. Each warehouse object is composed of one current state, several p...

Warehouse is one of the most important components in logistics of the supply chain network. Efficiency of warehouse operations is influenced by many different factors. One of the key factors is the racks layout configuration. A warehouse with good racks layout may significantly reduce the cost of warehouse servicing. The objective of this paper is to give a scheme for building warehouses models...
