This research seeks to find an optimal use of systems engineering in proposal management to maximize the probability that a supplier organization will be awarded contracts. A number of systems engineering related factors that can potentially be used to predict contract awards are identified that pertain to the organization, the skill levels of employees, the competitive environment, the proposal project, the contract, …

Rfid And Rtls Enhancement For Retained Surgical Instrument In The Body, Ida Lumintu

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

Retained surgical items (e.g., sponges, needles, and instruments) are classified as preventable medical errors that cost the United States about $17 to $29 billion each year and the most frequently reported sentinel events in 2011 as reported by the Joint Commission. This research proposes a new approach to decrease such preventable medical errors by developing a Radio Frequency Identification-based Real Time Locating System (RTLS) for surgical operations (RfSurg). Patient safety concern, e.g. the excessive exposure of x-ray to the patient after the surgery, is a major motivation behind the need of RTLS in this research. The use of RTLS techniques …

Simulation Modeling And Analysis Of Complex Port Operations With Multimodal Transportation, Mariam Kotachi, Ghaith Rabadi, Mohammad F. Obeid

Engineering Management & Systems Engineering Faculty Publications

World trade has been increasing dramatically in the past two decades, and as a result containers exchange has grown significantly. Accordingly, container terminals are expanding to meet this increase and new container ports have opened. Ports with one or more container terminals are considered complex systems in which many resources, entities and transporters interact to achieve the objective of safely moving containers delivered by ships inland as well as loading containers delivered by trucks and rail onto ships. Ports with multimodal transportation systems are in particular complex as they typically operate with ships arriving to one or more terminals, multiple …

A Theory Of Emergence And Entropy In Systems Of Systems, John J. Johnson Iv, Andreas Tolk, Andres Sousa-Poza

Engineering Management & Systems Engineering Faculty Publications

Systems of Systems (SOS) meet vital needs in our society by providing capabilities that are not possible by their discrete components or subsystems. Some SOS are engineered to produce predictable results, yet they can still display emergent behavior. These behaviors are often considered negative because they are not a function of the design. However, emergent behavior can also be serendipitous and produce unexpected positive results. The authors formalize a theory of emergence based on entropy. The theory has explanatory value for emergence as an ontological and phenomenological concept in systems of systems. © 2013 The Authors.

Determining Stakeholder Influence Using Input-Output Modeling, Patrick T. Hester, Kevin Macg. Adams

Engineering Management & Systems Engineering Faculty Publications

Stakeholders are a vital element in all complex systems problems. They are customers, users, clients, suppliers, employees, and team members. They fund the system, design it, build it, operate it, use it, maintain it, and dispose of it. While many approaches exist for classifying and determining their attitudes, these approaches stop short of evaluating stakeholders in a holistic manner. This paper closes this research gap by developing the metric of stakeholder situation influence, a measure which allows for quantitative evaluation of stakeholder influence on a given problem. This measure is derived from Leontief Input-Output analysis. The developed approach extends previous …

Thinking Systemically About Complex Systems, Patrick T. Hester, Kevin Macg. Adams

Engineering Management & Systems Engineering Faculty Publications

As machine age problems have given way to systems age messes, the underlying complexity associated with understanding these situations has increased exponentially. Accordingly, the methods we use to address these situations must evolve as well. Unfortunately, many antiquated methods for dealing with situations remain prominent. Systems engineering, traditionally, is the practical application of procedural problem solving, typically geared toward the acquisition of large-scale systems. The underlying paradigm for solving these problems can be characterized as systematic thinking. While quite appropriate for machine age problems, this approach lacks the theoretical rigor to deal with systems age messes. Thus, a new paradigm …

Prediction Of Foreign Object Debris/Damage Fod Type Based In Human Factors For Aeronautics Using Logistic Regression Model, David Ricardo Romo

Open Access Theses & Dissertations

Foreign Object Debris/Damage (FOD) has been an issue for military and commercial aircraft manufacturers since the early ages of aviation and aerospace. Currently, aerospace is growing rapidly and the chances of FOD presence are growing as well. One of the principal causes in manufacturing is the human error. The cost associated with human error in commercial and military aircrafts is approximately accountable for 4 billion dollars per year. This problem is currently addressed with prevention programs, elimination techniques, and designation of FOD areas, controlled access, restrictions of personal items entering designated areas, tool accountability, and the use of technology such …

Simulation-Based Cognitive Workload Modeling And Evaluation Of Adaptive Automation Invoking And Revoking Strategies, Christina Rusnock

Electronic Theses and Dissertations

In human-computer systems, such as supervisory control systems, large volumes of incoming and complex information can degrade overall system performance. Strategically integrating automation to offload tasks from the operator has been shown to increase not only human performance but also operator efficiency and safety. However, increased automation allows for increased task complexity, which can lead to high cognitive workload and degradation of situational awareness. Adaptive automation is one potential solution to resolve these issues, while maintaining the benefits of traditional automation. Adaptive automation occurs dynamically, with the quantity of automated tasks changing in real-time to meet performance or workload goals. …

Evaluation Of Quality And Sustainability Incentives To Optimize The Indonesian To The United States Crude Oil Supply Chain, Restu Purwaningtyas Sunarto-Bussey

Industrial, Manufacturing, and Systems Engineering Dissertations - Archive

The New York Times explained that the United States increased its dependence on oil from Saudi Arabia by more than 20 percent last year (Krauss 2012). The United States of Energy Information Administration (U.S. EIA) stated that oil from Saudi Arabia was accounted for 14 percent of the U.S. crude oil and petroleum products in 2012 ("Oil: Explained" 2012). This is problematic due to the fact that 14 percent of the U.S. net crude oil and petroleum products imports come from one country, Saudi Arabia. What happens to the U.S. economy when Saudi Arabia manipulates demand and possibly stops exporting …

Investigation Into The Measure, Correlate And Predict Methodologies Used In Wind Farm Design Software, Brendan O'Sullivan

Theses

This paper is focused on the Measure Correlate and Predict (MCP) methodologies used to estimate long term wind resource at a prospective site. The first common step in all MCP methodologies is a successful wind measurement campaign at the prospective site. This campaign involves the erection of a wind measurement mast (ideally to the hub height of the proposed turbine) and careful selection of booms, mountings and anemometers. The wind measurement campaign is a vital part of the process as the correlation and prediction analysis is only as accurate as the measured wind data. Correlation is a measure of the …

Analysis Of A Multi-Server Queueing Model With Vacations And Optional Secondary Services, Srinivas R. Chakravarthy

Industrial & Manufacturing Engineering Publications

In this paper we study a multi-server queueing model in which the customer arrive according to a Markovian arrival process. The customers may require, with a certain probability, an optional secondary service upon completion of a primary service. The secondary services are offered (in batches of varying size) when any of the following conditions holds good: (a) upon completion of a service a free server finds no primary customer waiting in the queue and there is at least one secondary customer (including possibly the primary customer becoming a secondary customer) waiting for service; (b) upon completion of a primary service, …

Scheduling In Mohs Micrographic Surgery Clinics, Stephen Vincent Steidle

Open Access Theses

Mohs Micrographic Surgery (MMS) is a surgical method used for the excision of aggressive skin cancers in areas of high cosmetic importance, such as the face and hands. The practice has been gaining popularity worldwide for its low recurrence rates and cosmetic results. Current clinics though are plagued by extreme wait times and an overall poor patient experience. In this paper we look to explore this problem by applying systems engineering principles including optimization and scheduling with the goal of improving the patient experience. Currently, little literature exists exploring the difficulties associated with scheduling for MMS clinic which primarily revolve …
