Lifecycle Cost Evaluation Of Flexible Facility Designs, Trevor P. Ellis
Lifecycle Cost Evaluation Of Flexible Facility Designs, Trevor P. Ellis
Theses and Dissertations
The purpose of this research is to ascertain the type of facility design, standard, robust, or flexible, that yields the greatest lower lifecycle costs (LCC) savings to the USAF. To this aim, the researcher constructed a Monte Carlo simulation to determine the LCC for flexible, robust, and standard administrative facility designs for thousands of potential facility lifecycles. The simulation also illustrates the circumstances under which each type of design would result in the lowest LCC. The results of this research will show the USAF the importance of focusing on LCC and designing flexible facilities. Standard and robust designs are the …
Independent Verification And Validation Of The Hazardous Material Cost Trade-Off Analysis Tool Developed By The Human Systems Center At Brooks Air Force Base, Thomas S. Choi
Theses and Dissertations
The Air Force realizes that the life cycle cost (LCC) associated with hazardous materials is a significant cost in the acquisition of major weapon systems. In trying to mitigate the growth of environmental LCC for future weapon systems, the Air Force has developed a tool called the Hazardous Material Cost Trade-off Analysis Tool (HAZMAT CTAT). The HAZMAT CTAT estimates the LCC for weapon system hazardous materials, so that intelligent decisions can be made in the early stages of the acquisition process. The problem with implementing this program into the acquisition process is that an independent computer model evaluation has never …
A Model For Forecasting Pollution Prevention Life Cycle Costs For Air Force Major Weapon Systems, Mark E. Garner, Jennifer S. Kirchoffer
A Model For Forecasting Pollution Prevention Life Cycle Costs For Air Force Major Weapon Systems, Mark E. Garner, Jennifer S. Kirchoffer
Theses and Dissertations
This research effort developed a modification to the HAZMAT program so that the program could provide the user with the capability to generate an estimate during the concept exploration and design phases for the total costs associated with hazardous materials usage in a major weapon system. Using the HAZMAT database, a spreadsheet was developed which projects a cost for a weapon system based on its total surface area and the number of aircraft to be produced by performing an analogy with a similar weapon system. The modification uses algorithm which are based on the hazardous material substances rather than processes …
Life-Cycle Cost Analysis For Radioactive Waste Remediation Alternatives, Thomas P. White, Ronald J. Toland, Dorian Y. Buitrago
Life-Cycle Cost Analysis For Radioactive Waste Remediation Alternatives, Thomas P. White, Ronald J. Toland, Dorian Y. Buitrago
Theses and Dissertations
This research has two primary objectives. The first is to develop a generic, interactive, spreadsheet-based life-cycle cost model that uses net present value and risk analysis techniques for cost comparison. The second is to apply the model specifically to the vitrification and cementation methods of waste remediation. By using spreadsheet analysis and graphics capabilities, the model will provide direct and objective comparisons of remediation alternatives. Since vitrification is a new technology, the plant design and operations are conceptual. Therefore, computer simulation and engineering judgement are integral to the vitrification LCC estimate.
A Decision Support Model Using Life Cycle Cost (Lcc) Analysis To Select Cost-Effective Alternatives For Hazardous Materials, Blaine F. Burley, Kirk A. Phillips
A Decision Support Model Using Life Cycle Cost (Lcc) Analysis To Select Cost-Effective Alternatives For Hazardous Materials, Blaine F. Burley, Kirk A. Phillips
Theses and Dissertations
This research focuses on the development of a decision support model to select cost-effective alternatives for hazardous materials using life cycle cost (LCC) analysis. The model provides an effective decision-making tool to evaluate the economic feasibility of using alternatives for hazardous materials. Given a specific operation, the users of this model can enter site-specific cost data to determine the total LCCs of using baseline hazardous materials (i.e., hazardous materials currently being used in an operation), as well as the total LCCs of using various alternatives. This thesis postulates that the material having the lowest total LCC is considered to be …
