Robust Sensitivity Analysis Of Courses Of Action Using An Additive Value Model, Hunter A. Marks
Robust Sensitivity Analysis Of Courses Of Action Using An Additive Value Model, Hunter A. Marks
Theses and Dissertations
The Department of Defense (DoD) requires the ability to quantifiably measure progress in arenas that are complex and difficult to measure, such as the stability of a region. Therefore, the DoD works diligently to predict the effect of operations and sponsors research to improve prediction and analysis. They desire a repeatable, systematic methodology to aid in the selection of courses of action (COA) that efficiently meet stated objectives and quantitatively measure the degree of accomplishment of these objectives. The author proposes a value-focused thinking (VFT) decision analysis (DA) approach to this problem. This methodology not only aids in selection of …
Value-Focused Thinking In The Presence Of Weight Ambiguity: A Solution Technique Using Monte Carlo Simulation, Timothy W. Porter
Value-Focused Thinking In The Presence Of Weight Ambiguity: A Solution Technique Using Monte Carlo Simulation, Timothy W. Porter
Theses and Dissertations
When a Decision Maker is asked to provide his or her preferences, the response represents a snapshot in time. While their preference structure elicited at any given moment may represent their revealed preferences at that point in time, it may change over time. These changing preferences over time represent ambiguity in the decision maker's preferences. Other sources of ambiguity may exist. One weakness of many decision analysis techniques today is the inability to incorporate ambiguity into the basic decision model. The existence of the problem has been known and commented on for many years. This research addresses that problem. It …
Linear Programming And Genetic Algorithm Based Optimization For The Weighting Scheme Of A Value Focused Thinking Hierarchy, David M. Thawley
Linear Programming And Genetic Algorithm Based Optimization For The Weighting Scheme Of A Value Focused Thinking Hierarchy, David M. Thawley
Theses and Dissertations
Deriving weights for a Value Focused Thinking (VFT) hierarchy demands considerable time and input from Decision Makers (DM) and Subject Matter Experts (SME). Often, the DMs and SMEs are the leaders of companies and organizations, and this required time is unrealistic with their schedules. In these situations, as well as scenarios where there no available DMs/SMEs, conventional means of weighting a VFT hierarchy are impossible, and any VFT analysis is halted. When historical data exists on evaluation measures and performance of alternatives, linear programming and genetic algorithm based optimization may be used to derive historically optimal weights for a hierarchy. …
Technology Selection For Enhancing F-16 Capability: An Analysis Using Value Focused Thinking, Cihangir Yay
Technology Selection For Enhancing F-16 Capability: An Analysis Using Value Focused Thinking, Cihangir Yay
Theses and Dissertations
This study, with support of the Aeronautical Systems center, builds a scientific decision support system intended for Air Combat Command. Past decision-making techniques are discussed and their limitations are explained. Two multiattribute decision-making techniques, analytical hierarch process and value focused thinking, are studied. Due to limitations of analytical hierarchy process, value focused thinking is accepted as the best fit for our problem. A value hierarchy model is developed using value focused thinking for selecting the most beneficiary F-16 engine modifications depending on Air Combat Command values. Ten modifications are ranked using value model to validate the process. Cost is involved …
