Girl’S Cybersecurity Camp, Sarah Cunha, Dale Rowe

Journal of Undergraduate Research

In 2015, the BYU Cybersecurity Research Lab (CSRL) held its first annual summer camp for Girls aged 14-18. A total of 38 girls attended the week’s activities and workshops. While over 75% of girls indicated they had taken a computing-related class, only 40% reported any significant interest in cybersecurity prior to the summercamp with 10% believing they had some experience in the field. At the conclusion of the camp, 80% of attendees reported a significant interest in the field with 100% of attendees interested in attending a similar event again.

Systemic Analysis Of Complex System Governance For Acquisition, Charles B. Keating, Joseph M. Bradley, Polinpapilinho F. Katina

Engineering Management & Systems Engineering Faculty Publications

The purpose of this paper is to explore Complex System Governance (CSG) issues related to systemic analysis of acquisition systems. CSG is an emerging field focused on the design, execution, and evolution of the functions necessary to provide continued system performance (stability) in the midst of incessant turbulence and increasing complexity. Integral to this field is the necessity to engage systems to address behavior or performance that is inconsistent with that which is desired. Systemic analysis for CSG serves to examine a system to discover fundamental system issues (e.g. acquisition). Arguably, system acquisition has an unremarkable record of success, ranging …

Cyber-Physical Systems: Complex System Governance As An Integrating Construct, Polinpapilinho F. Katina, Charles B. Keating, Adrian V. Gheorghe

Engineering Management & Systems Engineering Faculty Publications

This paper examines contributions of Complex System Governance (CSG) as an integrating construct for the emerging fields of critical cyber-physical systems (CPS). CPS is concerned with physical entities that are controlled by computational elements. The field is relatively new, emerging, and also somewhat fragmented in development. There are multiple agencies, entities, and activities being undertaken to address a nexus of emerging issues (e.g., cybersecurity) in critical infrastructures. However, the development of critical CPS, as a field, albeit with good intentions and efforts, appears to be largely ‘self-organizing.’ In response, we suggest CSG as an organizing construct capable of provided a …

Complex System Governance For Acquisition, Joseph Bradley, Polinpapilinho Katina, Charles Keating

Engineering Management & Systems Engineering Faculty Publications

As acquisition processes have become more complex, they appear to no longer be governable by traditional approaches. Missed budgets, delayed deliveries, and expensive canceled systems appear to becoming more prevalent. Numerous investigations have been conducted attempting to elicit the factors that prevented success. Those systems that succeed in terms of usability, budget, and delivery schedule are the rarity and often become case studies themselves as we try to extract the characteristics that differentiate success from failure. A different viewpoint is to look at the acquisition system from the perspective of Complex Systems Governance (CSG). Recent developments in the field of …

The Role Of 'Metasystem' In Engineering A System Of Systems, Polinpapilinho F. Katina, Charles B. Keating, Joseph M. Bradley

Engineering Management & Systems Engineering Faculty Publications

Fundamentally, a system of systems is characterized by operational independence, managerial independence, evolutionary development, emergent behavior, and geographical distribution. However, value-wise, a system of systems should provide greater capability beyond that which individual systems can provide. Enabling this greater capability has to be purposely designed for and managed. In this paper, we argue that this is the primary role of the metasystem structure and its execution. A metasystem is a governing structure that provides coordination and integration of multiple systems, brought together to achieve overarching missions and functions beyond those of the constituent systems. This paper articulates the differences between …

Statistical Engineering: A Causal-Stochastic Modeling Research Update, Teddy Steven Cotter

Engineering Management & Systems Engineering Faculty Publications

In the ASEM-IAC 2012, Cotter (2012) summarized prior works that led to the proposal for statistical engineering, identified the gaps in knowledge that statistical engineering needs to address, explored additional gaps in knowledge not addressed in the prior works, set forth a working definition of and body of knowledge for statistical engineering, and set forth proposals of potential systems contributions the Engineering Management profession could make toward the development of statistical engineering. In 2014, the ASQ Statistics Division, DOT&E, NASA, and IDA co-sponsored a Statistical Engineering Agreement to jointly research development of the discipline of statistical engineering. The statistics community …

Simulation Modeling And Analysis Of Customs-Regulated Container Terminal Operations With Multimodal Transportation, Mariam A. Kotachi

Engineering Management & Systems Engineering Theses & Dissertations

World trade has been increasing dramatically in the past two decades and, as a result, container exchange has grown significantly. Consequently and to meet this increase, several container terminals are expanding and many new ones are being established. A port with one or more container terminals is considered a complex system in which many entities interact to accomplish seamless handling of containers inbound and outbound. The level of complexity is drastically heightened for container terminals containing multimodal transportation systems as they typically involve ships, rail, and trucks arriving to one or more terminals delivering containers of different sizes to several …

Research Methodologies: A Look At The Underlying Philosophical Foundations Of Research, Nathapon Siangchokyoo, Andres Sousa-Poza

Engineering Management & Systems Engineering Faculty Publications

Quantitative and qualitative research methodologies have had their greatest share of debates dating back to the 1970s. Researchers have long argued over the underlying philosophical features between the two methodologies and their ability to derive knowledge (Onwuegbuzie & Leech, 2005, Sale, Lohfeld, & Brazil, 2002; Powell, Mihalas, Onwuegbuzie, Suldo and Daley, 2008; Sechrest and Sidani, 1995). More recently, modern researchers have argued that the integration of quantitative and qualitative methods into a single methodology (known simply as mixed methods research) allows researchers to answer questions otherwise unobtainable (Carey, 1993). The emergence of mixed methods research has gained increasing popularities in …

Modeling And Evaluating Role And Team Work Processes Using The Improved Performance Research And Integration Tool, Holly A. H. Handley, Pilar Pazos

Engineering Management & Systems Engineering Faculty Publications

The Human View architecture was designed to capture the human requirements of a system and to answer questions about the interactions between humans and systems. Data captured in the Human View can be used to populate a simulation model to evaluate the performance of the humans interacting in a work process. The work process model can be used to investigate different types of human system analyses, at both the role and team levels, and to identify the appropriate metrics to evaluate the results. This study examined individual role performance using the metrics readily available in the simulation tool, and then …

Examination Timetabling With Mathematical Programming An Application In Turkish Air Force Academy, Emrah Koksalmis

Engineering Management & Systems Engineering Theses & Dissertations

The focus of this thesis is the educational timetabling problem, which is a very challenging problem to solve especially with a high number of the departments, branches, classes, and students. Due to the large scale of educational timetabling problems and preferences of the stakeholders, it is almost impossible to form a general model that solves all of the timetabling problems in the literature. This resulted in the need to develop and employ specific models for specific institutions.

The purpose of this study is to develop a mathematical programming model that solves the examination timetabling problem in Turkish Air Force Academy …

The Role Of Feedback In The Assimilation Of Information In Prediction Markets, Richard Donald Jolly

Dissertations and Theses

Leveraging the knowledge of an organization is an ongoing challenge that has given rise to the field of knowledge management. Yet, despite spending enormous sums of organizational resources on Information Technology (IT) systems, executives recognize there is much more knowledge to harvest. Prediction markets are emerging as one tool to help extract this tacit knowledge and make it operational. Yet, prediction markets, like other markets, are subject to pathologies (e.g., bubbles and crashes) which compromise their accuracy and may discourage organizational use.

The techniques of experimental economics were used to study the characteristics of prediction markets. Empirical data was gathered …

How To Improve Project Management For Agile Federation Development, Priyanka Kotikalpudi

Engineering Management & Systems Engineering Theses & Dissertations

Developing a simulation federation out of a variety of heterogeneous simulation solutions is a complex task requiring very effective project management support in order to accomplish the common objectives and goals of this M&S federation. This thesis study conducts a detailed survey of available literature to identify the project management methods that can be extended to be applied to manage the development of simulation systems. The literature review led to the following two main results: (a) in general, there is insufficient literature dealing with M&S challenges for project management, (b) in particular, the two challenges of often changing requirements leading …

A Study Of Reticle Non-Flatness Induced Image Placement Error In Extreme Ultraviolet Lithography, Sudharshanan Raghunathan

Legacy Theses & Dissertations (2009 - 2024)

As the semiconductor industry continues scaling devices to smaller sizes, the need for next generation lithography technology for fabricating these small structures has always been at the forefront. Over the past few years, conventional optical lithography technology which has adopted a series of resolution enhancement techniques to support the scaling needs is expected to run out of steam in the near future. Extreme Ultra Violet lithography (EUVL) is being actively pursued by the semiconductor industry as one of the most promising next generation lithographic technologies. Most of the issues unique to EUVL arise from the use of 13.5 nm light …
