The data warehouse (DWH) is usually presented as a centralized database. In this paper, we propose a new approach to manage data storage and distribution in a data warehouse environment. This approach deals with the dynamic data distribution of the DWH on a set of servers. The data distribution that we consider is different from the “classical” one which depends on the data use. The distributio...

this paper presents a new formulation for warehouse inventory management in a stochastic situation. the primary source of this formulation is derived from fp model, which has been proposed by fletcher and ponnambalam for reservoir management. the new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. using this model, the expected value...

Data warehouses collect data from multiple remote sources and integrate the information as materialized views in a local database. The materialized views are used to answer queries that analyze the collected data for patterns, anomalies, and trends. This type of query processing is often called on-line analytical processing (OLAP). So that OLAP queries can be posed and answered easily, the data...

Logistics warehouse layout problem in circulation is one of the issues the enterprise concerned; storage as a logistics hub for transport links plays a role in the protection of stored products. During storage planning, in order to design a reasonable layout of warehouses, companies must consider seasonal product, quantity demand characteristics and the treasury itself highly characteristic and...

We investigate the effect of assigning the most-active items to the best locations in unitload warehouses with non-traditional aisles. Specifically, we report the performance of flying-V and fishbone designs when products exhibit different velocity profiles. We consider both singleand dual-command operations in a warehouse where receiving and shipping are located at the midpoint of one side of ...

The picking process is a critical supply chain component for many companies. A proper warehouse configuration, storage policy, trays replenishment policy, and other factors are also important to reduce not only the delivery time, but also increase productivity while maintaining quality factors at competitive costs. This paper presents an integrated approach to tackle the complexity of warehouse...

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 ...

We propose a simulated annealing algorithm specifically tailored to optimise total retrieval times in a multi-level warehouse under complex pre-batched picking constraints. Experiments on real data from a picker-to-parts order picking process in the warehouse of a European manufacturer show that optimal storage assignments do not necessarily display features presumed in heuristics, such as clus...

Waste ecologic storage is the main domestic waste treatment channel in EU. The paper describes the impact of a non-ecological warehouse existing in the municipality of Târgu-Jiu, upon the soil and the need for controlled storage of domestic waste and industrial waste. The necessary field for waste storage has to be mutually agreed upon with the local, sanitary, and environmental protection auth...

Determining the optimal storage assignment for products in a dedicated warehouse has been addressed extensively in the Facility Logistics literature. However, the process of implementing a particular storage assignment given the current location of products has not received much attention in the existing literature. Typically, warehouses use downtime or overtime to remove products from their cu...
