Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating...

An optimization model is used to evaluate the economics of various components of a large agribusiness. The benefits of using interger programming are contrasted to traditional linear programming analysis in conjunction with outside-the-model budgeting analysis.

Mathematical programming models can incorporate multiple objectives. Shadow prices in such models reflect a mixture of all of the objectives. A procedure is implemented to develop decomposed shadow prices applicable to the individual objectives. The procedure is demonstrated in a GAMS...

A mixed integer, goal programming model designed to aid in management of a meat packing plant is presented along with empirical applications demonstrating its use. Data collection, model conceptualization, model|data development, model refinement, and model use phases are discussed. The...

The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas...

Most municipalities use conventional treatment to produce potable water. Historically, desalination has not been economically feasible, but technological advancements warrant a new analysis. This study analyzes the costs of two Texas municipal facilities producing water using the above...

Arundo donax is a large, invasive weed consuming large quantities of water in the riparian area of the Texas Rio Grande Basin. With water availability a concern to the area, the USDA-ARS is investigating biological control agents to increase available water, creating a benefit to both the...

Two primary potable water-treatment technologies used in South Texas include conventional surface-water and reverse-osmosis (RO) desalination of brackish-groundwater. As the region's population continues to grow, municipalities are searching for economical means to expand their water supplies....

This case study investigates the effect of a change in cropping pattern involving expanded acres of crops for biofuel feedstock, on the discharge of nutrients to rivers. Annual data from 1968-2008 on stream flow, cropped acres, and precipitation for Wharton County, Texas are used. A positive...
