Item A decision support system for income-producing real estate development feasibility analysis and alternative assessment(Texas A&M University, 2005-08-29) Leelarasamee, YosapornThe purpose of this study is to design, develop, and evaluate a prototype scenarioassisted decision support system (DSS) for use in venture and alternative assessment during the predevelopment stage of income-producing real estate development. This research examines theoretical underpinnings and associated advancements related to income-producing real estate development and decision support systems. Particular emphasis was placed on synthesis of relating disciplines?? models and advancements that support design and development of the decision support system. The result of the system design and development are embodied in a prototype scenario-assisted decision support system for income-producing real estate development (DSSVenture). The design and development of the program are documented in this dissertation. Following the design and development stage, the validation of DSSVenture??s data and logic models was conducted based on two case studies from well-known real estate development publications. The system was then tested on a group of graduate students who enrolled in an advanced real estate development course at Texas A&M University to examine whether its facilitation objective had been achieved. Since this research hypothesized that the decision support system would facilitate developers?? decision making during predevelopment stage of income-producing real estate development, three operational variables were tested, namely number of alternatives examined, time to reach decisions, and coefficient of projected net present value variations. The testing results indicate that DSSVenture system significantly enhances comprehensiveness of the decision context by increasing the number of alternatives for developers. Since the use of the system significantly reduces developers?? time to reach decisions, the efficiency of decision making is improved. Finally, the results of the study confirm that the use of DSSVenture system substantially diminishes variation of profit projection among decision makers. Therefore, the facilitation objective is achieved.Item Development of a Decision Support Geographic Information System for land restoration programs in the Leon, Lampasas, and Bosque River Watersheds(Texas A&M University, 2006-10-30) Jones, Jason SamuelAshe Juniper encroachment onto privately owned rangelands in Central Texas has resulted in significant degradation of the ecological condition of these lands, and a subsequent public concern for the hydrologic function, wildlife habitat, and livestock production these historically predominant grasslands provide. The result has been an interest and public investment in land restoration programs such as the removal and management of brush via landowner cost-share. Implementation of a publicly funded land restoration program requires the allocation of millions of dollars of public funds on private lands over large geographic areas that represent hundreds of landowners with varying property management objectives, tract sizes, ecological conditions, and geologic characteristics. This study describes the development, accuracy, and application of a decision support geographic information system (DSGIS) for land restoration programs in the Leon, Lampasas, and Bosque River watersheds in the Brazos River basin of Central Texas. The spatially referenced data layers and associated database within the DSGIS provide the capability to assemble site specific information including vegetation cover, endangered species habitat, landowners, ecological sites, elevation and slope, hydrologic characteristics, and political boundaries to support policy and implementation decisions for Ashe Juniper (Juniperus ashei) brush control and management and goldencheeked warbler (Dendroica chrysoparia) habitat restoration programs. The goldencheeked warbler is a federally listed endangered species with a breeding range limited to the oak-juniper woodlands of Central Texas. The data layers were developed with the support of ongoing research from the Leon River Restoration Project (LRRP) in Coryell and Hamilton counties. One hundred and eighty-eight (188) sub-watersheds were delineated within the project area and prioritized for implementation of an Ashe Juniper brush control program and a golden-cheeked warbler habitat restoration program. Costs associated with the clearing and stacking of Ashe Juniper were estimated for selected subwatersheds based on projected landowner participation and an analysis of actual costs from the LRRP. Sub-watersheds were targeted for the implementation of an Ashe Juniper brush control and golden-cheeked warbler habitat management program in Bosque, Coryell, Lampasas, Bell, and Burnet counties. Detailed tables were also developed to document the density and quantity of pertinent layer attributes within each of the 188 sub-watersheds.
