We consider the problem of preparing for a disaster season by determining where to open warehouses and how much relief item inventory preposition in each. Then, after each disaster, prepositioned items are distributed demand nodes during post-disaster phase, additional procured as needed. There is often uncertainty level, affected areas’ locations, items, usable fraction post-disaster, procurem...

The purpose of data warehouses is to enable business analysts to make better decisions. Over the years the technology has matured and data warehouses have become extremely successful. As a consequence, more and more data has been added to the data warehouses and their schemas have become increasingly complex. These systems still work great in order to generate pre-canned reports. However, with ...

Data warehouses and OLAP systems help to analyze complex multidimensional data and provide decision support. With the availability of large amounts of spatial data in recent years, several new models have been proposed to enable the integration of spatial data in data warehouses and to help analyze such data. This is often achieved by a combination of GIS and spatial analysis tools with OLAP an...

An approach for organizing the information in the data warehouses is presented in the paper. The possibilities of the numbered information spaces for building data warehouses are discussed. An application is outlined in the paper.

Many data warehouses contain massive amounts of data and grow rapidly. Examples include warehouses with retail sales data capturing customer behavior and warehouses with click-stream data capturing user behavior on web sites. The sheer size of these warehouses makes them increasingly hard to manage and query efficiently. As time passes, old, detailed data in the warehouses tend to become less i...

The maintenance of data warehouses is becoming an increasingly important topic due to the growing use, derivation and integration of digital information. Most previous work has dealt with one centralized data warehouse (DW) only. In this paper, we now focus on environments with multiple data warehouses that are possibly derived from other data warehouses. In such a large-scale environment, data...

Four vitamins were analyzed in several fruit and vegetable commodities to evaluate the differences between fresh and frozen produce. Ascorbic acid, riboflavin, α-tocopherol, and β-carotene were evaluated in corn, carrots, broccoli, spinach, peas, green beans, strawberries, and blueberries. Samples of each commodity were harvested, processed, and analyzed for nutrient content at three storage ti...

Because current literature on globalization largely neglects racism, it fails to explain the experiences of contemporary African American youth within the new racialized social class formations of globalization. I suggest that because African American youth live within the borders of the sole remaining world superpower, their experiences might shed light on social class relations of advanced ca...
