Cross docking is a warehouse management concept in which items delivered to a warehouse by inbound trucks are immediately sorted out, reorganized based on customer demands and loaded into outbound trucks for delivery to customers, without requiring excessive inventory at the warehouse. Compared to traditional warehousing, the storage as well as the length of the stay of a product in the warehou...

This article will introduce an inventory model for deteriorating items under a ramp-type demand rate. In the sequel, preservation technology has appeared to reduce deterioration rate of items. The is considered time-dependent. Due demand, retailers may face complete and partial backlogged shortages. We suggest two-warehouse effect when retailer faces storage capacity problem. this model, it wou...

Soybean seed is usually not carried-over to the next planting season because it deteriorates rapidly in storage, resulting in poor growth when planted. This rapid deterioration is a serious problem in seed production. The short shelf life of soybean seed is the result of its high lipid content and high levels of polyunsaturated linolenic and linoleic acids. The soybean production practice of pl...

Although Red Brick performance depends primarily on the logical database design, the placement and allocation of data files in the disk subsystem is another significant performance factor. There are many choices in the configuration and design of the physical database layout. This article reviews best practices propagated by storage and database vendors and presents measurements that compare st...

Erasure codes, such as Reed-Solomon (RS) codes, are being increasingly employed in data centers to combat the cost of reliably storing large amounts of data. Although these codes provide optimal storage efficiency, they require significantly high network and disk usage during recovery of missing data. In this paper, we first present a study on the impact of recovery operations of erasure-coded ...

INTRODUCTION Blood transfusion has health-related, economical and safety implications. In order to optimise the transfusion chain, comprehensive research data are needed. The Dutch Transfusion Data warehouse (DTD) project aims to establish a data warehouse where data from donors and transfusion recipients are linked. This paper describes the design of the data warehouse, challenges and illustra...

A data warehouse stores materialized views derived from one or more sources for the purpose of eeciently implementing decision-support or OLAP queries. One of the most important decisions in designing a data warehouse is the selection of materialized views to be maintained at the warehouse. The goal is to select an appropriate set of views that minimizes total query response time and/or the cos...

This paper considers routing and layout issues for parallel aisle warehouses. In such warehouses order pickers walk or drive along the aisles to pick products from storage. They can change aisles at a number of cross aisles. These cross aisles are usually located at the front and back of the warehouse, but there can also be one or more cross aisles at positions in between. We describe a number ...
