Simulation Analysis On Alternatives To Accelerate The Passenger Flow In Security Checkpoints, Maria Luisa Janer Rubio

Industrial Engineering Undergraduate Honors Theses

This study consists of discrete event simulation analysis of two alternative solutions designed to mitigate the congestion of passengers in the exit roller area of the security checkpoints. We study the particular case of Orlando International Airport, where this problem is prominent due to the high proportion of passengers who travel for leisure purposes. We developed three simulation models to represent the current configuration and the two alternative solutions. We compare the solutions to the current configuration by observing the response of the passenger throughput and passenger system time when performing a sensitivity on the percentage of passengers throughput. We …

Optimization Of Support Structures For Selective Laser Melting., Kai Zeng

Gaucher disease (GD) is a lysosomal storage disorder; symptomatic patients with type 1 GD need long-term disease-specific therapy of which the standard of care has been enzyme replacement therapy (ERT). Thirty-eight of 40 patients (aged 9–71 years) clinically stable on ERT with imiglucerase, safely switched to a comparable dose of velaglucerase alfa (units/kg) during TKT034, a 12-month, open-label clinical study, and for 10–50 months in an extension study. The most common adverse events (AEs) judged to be drug-related in the extension were fatigue and bone pain. No drug-related serious AEs were reported. No AEs led to study withdrawal. At 24 …

Type 1 Gaucher disease is an inherited lysosomal enzyme deficiency with variable age of symptom onset. Common presenting signs include thrombocytopenia, anemia, hepatosplenomegaly, bone abnormalities, and, additionally in children, growth failure. Fifty-seven patients aged 3–62 years at the baseline of two phase III trials for velaglucerase alfa treatment were enrolled in the single extension study. In the extension, they received every-other-week velaglucerase alfa intravenous infusions for 1.2–4.8 years at 60 U/kg, although 10 patients experienced dose reduction. No patient experienced a drug-related serious adverse event or withdrew due to an adverse event. One patient died following a convulsion that was …

An Adaptive Large Neighborhood Search Heuristic For The Inventory Routing Problem With Time Windows, Mina Hadianniasar

Graduate Theses and Dissertations

This research addresses an integrated distribution and inventory control problem which is faced by a large retail chain in the United States. In their current distribution network, a direct shipping policy is used to keep stores stocked with products. The shipping policy specifies that a dedicated trailer should be sent from the warehouse to a store when the trailer is full or after five business days, whichever comes first. Stores can only receive deliveries during a window of time (6 am to 6 pm). The retail chain is seeking more efficient alternatives to this policy, as measured by total transportation, …

Creating Quality Metrics For The Capital Facilities Delivery Industry, Kelsey D. Lamb

Graduate Theses and Dissertations

A standard for industry-wide quality metrics, similar to safety metrics, for the capital facilities delivery industry is investigated and developed with the goal to motivate industry-wide adoption of this new quality metric program. A survey of the literature found key differences between capital facilities and other industries, mainly that other industries focus on the quality of the product while capital facilities focus on maintaining the cost and schedule of a project. Creating a framework that can be used across the industry can potentially lead to uniform improvement of quality for the entire industry. Quality is defined for the capital facilities …

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.

Cost Effective Analysis Of Big Data, Steven J. Litzsinger, Nehad Dababo

Industrial and Manufacturing Engineering

Executive Summary

Big data is everywhere and businesses that can access and analyze it have a huge advantage over those who can’t. One option for leveraging big data to make more informed decisions is to hire a big data consulting company to take over the entire project. This method requires the least effort, but is also the least cost effective. The problem is that the know-how for starting a big data project is not commonly known and the consulting alternative is not very cost effective. This creates the need for a cost effective approach that businesses can use to start …

Dcpp/Polygait Inventory Control System, Logan Pace, Robert Garlinghouse

Industrial and Manufacturing Engineering

This report discusses a proposed system to improve upon inventory management issues experienced in the M&TE Tool room for the PG&E Diablo Canyon Power plant. Effective inventory tracking and management is an important characteristic of any organization handling physical assets, and without the proper system in place, companies may lose expensive items and waste time by not having equipment available when needed. The tool room is experiencing inventory shrinkage of M&TE equipment nearing $100,000 per year largely because of an inefficient checkout system that fails to keep employees accountable for the tools they check out. Even more costly than the …

Void Modeling In Resin Infusion, Mark Wesley Brandley

Theses and Dissertations

Resin infusion of composite parts has continually been reaching to achieve laminate quality equal to, or exceeding, the quality produced with prepreg in an autoclave. In order for this to occur, developers must understand the key process variables that go in to producing a laminate with minimal void content. The purpose of this research is to continue efforts in understanding 1) the effect of process conditions on the resultant void content, with a focus on resin infusion flow rate, 2) applying statistical metrics to the formation, location and size of voids formed, and 3) correlate these metrics with the local …
