Evaluating Launch Vehicle / Reentry Vehicle (Lv/Rv) Separation Concepts, Zheng Tao, Ganghuai Wang, Tudor Masek, Thomas J. St. Clair

Space Traffic Management Conference

Launch Vehicle/Reentry Vehicle (LV/RV) operations are expected to increase across the National Airspace System (NAS) as their reliability and availability improve. LV/RV designs and the industry landscape have vastly changed since the 1960’s, and the Federal Aviation Administration’s (FAA) methods for handling these operations need to evolve to support the expected growth. Currently, large amounts of airspace are segregated for every LV/RV operation. This increases costs for NAS users and may limit LV/RV opportunities. The FAA’s NextGen office recently proposed two more efficient separation concepts for LV/RV operations called Space Transition Corridors, and Four-Dimensional Trajectory Deconfliction. Prior safety research for …

A Method Of Mapping Sinkhole Susceptibility Using A Geographic Information System: A Case Study For Interstates In The Karst Counties Of Virginia, Alexandra L. Todd, Lindsay Ivey-Burden

Sinkhole Conference 2015

Karst terrain is landscape underlain by limestone that has been chemically dissolved by acidic groundwater, producing subsurface voids that pose risks for sinkholes if the overlaying soils can no longer support their own weight and collapse. The western counties of Virginia are heavy in karst due to their natural, geographic boundary of the western Ridge Province and the eastern Blue Ridge Mountain Range. As a result, the Commonwealth of Virginia Hazard Mitigation Plan recommends that the Virginia Department of Transportation (VDOT) develop a method to determine the roadways and regions most susceptible to experiencing sinkholes, in an effort to reduce …

A Machine Learning Approach To Post-Market Surveillance Of Medical Devices, Jonathan Bates, Shu-Xia Li, Craig Parzynski, Ronald Coifman, Harlan Krumholz, Joseph Ross

Yale Day of Data

Post-market surveillance is a collection of processes and activities used by product manufacturers and regulators, such as the U.S. Food and Drug Administration (FDA) to monitor the safety and effectiveness of medical devices once they are available for use “on the market”. These activities are designed to generate information to identify poorly performing devices and other safety problems, accurately characterize real-world device performance and clinical outcomes, and facilitate the development of new devices, or new uses for existing devices. Typically, a device is monitored by comparing adverse events in the exposed population to a matched unexposed population. This research considers …

Customer Complaint Management Systems (Ccms) In A Food Processing Industry, Maggie A. Macleish

Senior Honors Projects, 2010-2019

Abstract

The food processing industry must meet customers’ highest quality expectations at the lowest cost. I partnered with Nestlé’s pizza facility in Little Chute, WI, to improve the current customer complaint approach of the quality department, which aimed to improve product quality. To improve the total quality of the system, this project established a defensive method of addressing customer complaints. Some strategies used to improve the current Customer Complaint Management System (CCMS) include Quality Functional Deployment (QFD), fuzzy logic, Kano’s methods, Voice of the customer (VOC) and Go-See-Think-Do (GSTD). These strategies are all related, but have not previously been used …

Chesapeake Bay Blue Crabs And Consumption Related Illness, Caitlin M. Shipman

Senior Honors Projects, 2010-2019

Currently, 72.2% of the Chesapeake Bay is impaired due to pollutants that impaired water quality. Some common pollutants in the Bay that are also toxic if consumed are: polychlorinated biphenyls (PCBs), mercury, and lead. Pollutants tend to settle on the Bay floor and become accumulate in the sediment. Most shellfish and small finfish live near or on the Bay floor and are may be exposed to high levels of pollutants. Therefore, bioaccumulation and biomagnification of pollutants can occur in shellfish and finfish tissues. These pollutants may cause a risk to human health by either increasing the risk of developing cancer …

Software In Military Aviation And Drone Mishaps: Analysis And Recommendations For The Investigation Process, Veronica Foreman, Francesca Favaro, Joseph Saleh, Christopher Johnson

Faculty Publications

Software plays a central role in military systems. It is also an important factor in many recent incidents and accidents. A safety gap is growing between our software-intensive technological capabilities and our understanding of the ways they can fail or lead to accidents. Traditional forms of accident investigation are poorly equipped to trace the sources of software failure, for instance software does not age in the same way that hardware components fail over time. As such, it can be hard to trace the causes of software failure or mechanisms by which it contributed to accidents back into the development and …

A Risk Based Approach To Node Insertion Within Social Networks, Chancellor A. J. Johnstone

Theses and Dissertations

Social Network Analysis (SNA) is a primary tool for counter-terrorism operations, ranging from resiliency and influence to interdiction on threats stemming from illicit overt and clandestine network operations. In an ideal world, SNA would provide a perfect course of action to eliminate dangerous situations that terrorist organizations bring. Unfortunately, the covert nature of terrorist networks makes the effects of these techniques unknown and possibly detrimental. To avoid potentially harmful changes to enemy networks, tactical involvement must evolve, beginning with the intelligent use of network in filtration through the application of the node insertion problem. The framework for the node insertion …

Risk Management In Motorway Ppp Projects: Empirical-Based Guidelines, Nunzia Carbonara, Nicola Costantino, Louis Gunnigan, Roberta Pellegrino

Articles

This paper deals with the topic of risk management in Public–Private Partnership (PPP). The analysis of the related literature reveals that risks must be analyzed and managed on a context-specific approach, and that there is a lack of a comprehensive study on the appropriate risk mitigation strategies for each risk embedded in PPP projects. Focusing on the transport sector, based on the results of a Delphi survey, the paper provides guidelines for both public and private parties in defining a list of significant risks in PPP motorway projects, and identifying for them both the effective allocation and the suitable mitigation …

Third Party Airport Crash Risk Model For Non-Towered Airports, Christian Salmon

Aviation / Aeronautics / Aerospace International Research Conference

This research leverages the objective accident data record towards an individual and societal 3^rd party “external” airport risk model for aircraft operations that crash while operating at non-towered airports.

Small aircraft, specifically Part 91, operating at non-towered airports have a crash rate estimated at 10-fold that of commercial operations. Given the nature of the typically non-towered airport, situated in close physical proximity with residential structures, this exposes residents to substantive risk of injury and death due to aircraft crashing.

A 3^rd party risk model that maps risk of injury, death and percent structural damage will enable informed decisions …

The Identification Of Assessment Criteria For A Safety Reporting Self-Assessment Tool, Maria Chiara Leva, Samuel Cromie, Ewan Douglas

Conference papers

This paper describes the assessment criteria that have been identified for use within a self-assessment tool for risk reporting within an industrial context. An in-depth review of the available literature was carried out exposing the criteria discussed within this paper. The criteria target all areas of reporting from the design of the reporting interface to the cultural considerations and initiatives. These criteria will be refined and weighted using industrial case study experience and then developed into the full self-assessment tool.

A Simulation-Based Approach To Risk Assessment And Mitigation In Supply Chain Networks, Mamadou Seck, Ghaith Rabadi, Christian Koestler

Engineering Management & Systems Engineering Faculty Publications

We present in this paper a simulation-based approach to evaluate the risk associated with supply chain disruptions caused by failures in some supply chains nodes and measure the impact of such disruptions on supply chain key performance measures (KPIs) of interest. The proposed framework enables analysts and managers to repeatedly assess the risk to their supply chains based on various simulated scenarios and identify the most critical nodes whose disruption will have the highest impact on the KPIs of interest. As a result, companies can focus on the most critical supply chain assets and develop targeted mitigation plans that minimize …

Can Strategic Risk Management Contribute To Enterprise Risk Management? A Strategic Management Perspective, Phil Bromiley, Devaki Rau, Michael K. Mcshane

Finance Faculty Publications

Within the discipline of enterprise risk management (ERM), strategic risk management (SRM) has become a subject of increasing interest to practitioners and academics. To our knowledge, the term “strategic risk management” first appeared in the management literature in 1985 and 1986 (Jammine, 1985; Figenbaum & Thomas, 1986) and in the academic finance literature in 1990 (Rawls and Smithson, 1990), although early usage of the term did not clearly relate to later conceptions. The phrase has been in use even longer than ERM (Bromiley, McShane, Nair, and Rustambekov, 2014). Even with this longevity, the meaning of the term remains unclear, with …

Safety Culture Monitoring: A Management Approach For Assessing Nuclear Safety Culture Health Performance Utilizing Multiple-Criteria Decision Analysis, James Harold Warren Jr.

Engineering Management & Systems Engineering Theses & Dissertations

Nuclear power plants are among the most technologically complex of all energy facilities. This complexity reflects the precision needed in design, maintenance and operations to harness the energy of the atom safely, reliably and economically. Nuclear energy thus requires consistent, high levels of organizational performance by the highly skilled professionals who operate and maintain nuclear power plants (Nuclear Energy Institute [NEI], 2014, p. 1).

A key element for achieving consistent, high levels of performance in a nuclear organization is its safety culture. Nuclear safety culture is for an organization what character and personality is for an individual: a feature that …

The Simulation & Evaluation Of Surge Hazard Using A Response Surface Method In The New York Bight, Michael H. Bredesen

UNF Graduate Theses and Dissertations

Atmospheric features, such as tropical cyclones, act as a driving mechanism for many of the major hazards affecting coastal areas around the world. Accurate and efficient quantification of tropical cyclone surge hazard is essential to the development of resilient coastal communities, particularly given continued sea level trend concerns. Recent major tropical cyclones that have impacted the northeastern portion of the United States have resulted in devastating flooding in New York City, the most densely populated city in the US. As a part of national effort to re-evaluate coastal inundation hazards, the Federal Emergency Management Agency used the Joint Probability Method …
