Approximate Algorithms For The Combined Arrival-Departure Aircraft Sequencing And Reactive Scheduling Problems On Multiple Runways, Gulsah Hancerliogullari

Engineering Management & Systems Engineering Theses & Dissertations

The problem addressed in this dissertation is the Aircraft Sequencing Problem (ASP) in which a schedule must be developed to determine the assignment of each aircraft to a runway, the appropriate sequence of aircraft on each runway, and their departing or landing times. The dissertation examines the ASP over multiple runways, under mixed mode operations with the objective of minimizing the total weighted tardiness of aircraft landings and departures simultaneously. To prevent the dangers associated with wake-vortex effects, separation times enforced by Aviation Administrations (e.g., FAA) are considered, adding another level of complexity given that such times are sequence-dependent. Due …

The Rq-Tech Methodology: A New Paradigm For Conceptualizing Strategic Enterprise Architectures, Christine Ann Hoyland

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research is to develop and apply a system-theoretic based methodology and corresponding model for Enterprise Architecture development. Enterprise Architectures can assist managers by illustrating the systemic relationships within an organization and the impact changes to the organization could make. Unfortunately, today's modeling practices are proprietary, time-consuming, and generally ineffective as tools for understanding the consequences of strategic-level planning decisions across all levels of the enterprise. This research supports the conclusion that system-specific solutions produce islands of technology and can be prevented by employing better enterprise change planning.

This research combined the practice of Enterprise Architectures with …

Micro To Macro Dynamics Of Shared Awareness Emergence In Situations Theory: Towards A General Theory Of Shared Awareness, Samuel F. Kavacic

Engineering Management & Systems Engineering Theses & Dissertations

Engineering Management is an interdisciplinary field of study. As such, Engineering Management must rely on the energies of its participants to integrate toward the problem being solved. Many techniques exist to aid the researcher towards a common goal; however, it can only be surmised on how effective the techniques have been. Not until the activity is over and the participants reflect back on their results can they know whether they shared a common understanding of the problem. This study explores the emergence of shared awareness based the interactions of disparate perspectives at a particulate level. The study builds from observations …

An Expert Based Multi Attribute Group Decision Making (Magdm) Model For Portfolio Evaluation: Application On Ground Force Units, Metin Gultekin

Engineering Management & Systems Engineering Theses & Dissertations

This main objective of this dissertation is to propose an expert based multi attribute group decision making model (MAGDM) for portfolio evaluation and demonstrate it by applying it to evaluate brigade types under different military missions. Specifically, currently used Heavy, Mechanized Infantry, Airborne Infantry, and Stryker brigades are evaluated under a set of possible future military missions. The purpose of the study is to provide a model for decision makers, engaged in a force development process.

This study combined MAGDM and simulation by using expert judgments to create distributions rather than aggregating them into point values. Excel and Monte Carlo …

An Epistemological Inquiry Into The Incorporation Of Emergency Management Concept In The Homeland Security With A Post-Disaster Security Centric Focus, Mehmet Secilmis

Engineering Management & Systems Engineering Theses & Dissertations

The historical roots of the Emergency Management concept in the U.S. date back to 19th century. As disasters occurred, policies relating to disaster response have been developed, and many statuary provisions, including several Federal Disaster Relief Acts, conceptually established the framework of Emergency Management. In 1979, with the foundation of the Federal Emergency Management Agency (FEMA), disaster relief efforts were finally institutionalized, and the federal government acknowledged that Emergency Management included mitigation, preparedness, response and recovery activities as abbreviated 'MPRR.'

However, after 2000, the U.S. experienced two milestone events - the September 11 terrorist attacks in 2001 and Hurricane Katrina …

System Governance Analysis Of Complex Systems, Behnido Y. Calida

Engineering Management & Systems Engineering Theses & Dissertations

The purpose of this research was to develop and deploy a systems-based framework for analysis of complex governance systems using a multimethodology research design. Two research gaps motivated this research: (1) lack of an integrated conceptualization of a system governance construct, (2) an absence of studies that consider both the governed and governing systems as well as the emergent interactions that arise from within complex governance systems.

The research focused on three primary questions: (1) What are the distinctive characteristics of governance?; (2) What system-based framework can be developed for analysis of governance in complex systems?, and (3) What results …

Shared Leadership In Six Sigma Teams From The North Shore-Lij Health System, Brian J. Galli

Engineering Management & Systems Engineering Theses & Dissertations

The main goal of the research was to identify the relationships that the internal research team environment and external coaching variables had with the degree of shared leadership in the context of Six Sigma teams from the North Shore LIJ Health System. Furthermore, the research ascertained the relationships that these variables had with two performance metrics: a team's ability to complete project deliverables and satisfy customer's requirements. This research also sought to understand additional factors that affected the five variables.

The research found that while shared leadership did not positively change as a team progressed through the phases of the …

Naval Surface Warfare Center Dahlgren Division Engagement Systems (G) Department Development Of A Plan To Maintain, Expand, And Create Corporate Knowledge, Luis J. Rodriguez

Engineering Management & Systems Engineering Theses & Dissertations

This dissertation presents the implementation of an organizational study in a technical organization that provides basic information for proper decision making to establish, continue, nurture, modify, transfer or terminate a Knowledge Management (KM) practice. Different aspects of an organization influence the capability to create and retain knowledge. Understanding the factors and the environment of the KM problem in an organization is essential for a successful plan and execution of knowledge creation, transfer and retention. The study purpose was to describe the contextual situation of the organization in terms of Human, Structural and Relational Capital; identify critical knowledge for the organization …
