Value Focused Inland Waterway Infrastructure Investment Decisions, Othman Boudhoum

Graduate Theses and Dissertations

Maritime transportation functions as the backbone of world trade. The U.S. inland waterway transportation system is comprised of 12,000 miles of navigable waterways that connect and move freight between the global supply chain and thirty eight States. When investing in inland waterway infrastructure, we should aim to maximize all benefits associated with the investment including flood protection, water supply, hydropower generation, recreation, and environmental impact benefits. We formulate an initial qualitative value model for the inland waterway infrastructure investment decision based on a value-focused thinking approach which allows us to holistically evaluate project investment alternatives.

A Framework To Simplify The Choice Of Alternative Analysis And Selection Methods, James Paul Lewis Holzgrefe

Engineering Management & Systems Engineering Theses & Dissertations

This dissertation contributes a framework for analysts and engineering managers to investigate and choose alternative analysis and selection methods based upon their problem and its context. It began as an investigation into the alternative analysis and selection methods used in military planning. The existing military methods were inconsistent, violated the decision science body of knowledge, and provided no guidance to the practitioner on matching methods to problems. These challenges made it necessary to conduct this investigation.

This research used a three-phase mixed methods approach. The first phase applied the general inductive method to the decision making body of knowledge to …

Probabilistic Inference Based Message-Passing For Resource Constrained Dcops, Supriyo Ghosh, Akshat Kumar, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Distributed constraint optimization (DCOP) is an important framework for coordinated multiagent decision making. We address a practically useful variant of DCOP, called resource-constrained DCOP (RC-DCOP), which takes into account agents’ consumption of shared limited resources. We present a promising new class of algorithm for RC-DCOPs by translating the underlying co- ordination problem to probabilistic inference. Using inference techniques such as expectation- maximization and convex optimization machinery, we develop a novel convergent message-passing algorithm for RC-DCOPs. Experiments on standard benchmarks show that our approach provides better quality than previous best DCOP algorithms and has much lower failure rate. Comparisons against an …

Supply Chain Interoperability Measurement, Christos E. Chalyvidis

Theses and Dissertations

Academia recognizes that although supply chains have an inherent need to be validated for their performance, supply chain performance measurement systems are still inadequate and one of the major barriers to successful supply chain collaboration. In this research, theory of Systems Architecture is used to make the first step towards an innovative supply chain performance measure defined as supply chain interoperability. Interoperability is considered a similarity metric with regard to a set of deterministic and stochastic characters (criteria) describing supply chain participants, a methodology that adapts and expands an interoperability measurement tool initially developed in and for a military context. …

An Assessment Of The Effectiveness Of Air Force Risk Management Practices In Program Acquisition Using Survey Instrument Analysis, Michael J. Maroney Jr.

Theses and Dissertations

Air Force acquisition programs invest a large amount of resources to develop and field systems. Many of these resources go to risk management in order to help ensure those programs finish successfully with respect to cost, schedule, and technical performance goals. The question arises as to whether this is a sound investment. Although risk management has been shown to be effective in industry, scant empirical evidence exists for its effectiveness within the Air Force. Correlation and regression analysis of survey data show that a positive relationship does exist between specific risk practices and project success. Furthermore, the analysis suggests that …

Tensions In The Productivity In Design Task Tinkering – Fundamental, Gina Quan, Ayush Gupta

Faculty Publications

Tensions in the Productivity in Design Task TinkeringTinkering is an ad-hoc approach to a problem and involves the practice of manipulating objectsto characterize and build knowledge about a particular system in an exploratory way, often withthe goal of getting some product/idea to produce desired behavior (e.g. Turkle & Papert, 1991;Berland, 2013; Roth, 1996). Tinkering thus contrasts with more deliberate activity towardsunderstanding how some phenomenon works or towards achieving conceptual understanding.Some researchers have argued that tinkering is an unproductive process because it does notalways lead to progress and/or conceptual learning (Law, 1998; Yeshno & Ben-Ari, 2001).Others view it as productive for …
