Ethnic Difference In Healthcare Delivery, Benny Mathew Varghese Dec 2011

Ethnic Difference In Healthcare Delivery, Benny Mathew Varghese

Industrial and Management Systems Engineering -- Dissertations and Student Research

Quality in healthcare is a very important aspect; this is obtained when there is proper care provided to the patients without any discrimination. The healthcare system in the US can be improved in the fields of patient’s care, the amount of money spent and proper advice, if proper responsibilities are taken. Quality has been improving over the years, but the median by which there is an increase is too small. The other main factor is access to the healthcare system, which has over the year, has not progressed. Studies in healthcare quality should be conducted on a regular base ...


Economic Analysis Of Continuous Monitoring Of Commercial Truck Tire Pressure Using Tire Pressure Monitoring Systems (Tpms) And Rfid Technologies., Afolabi A. Ogunwemimo Dec 2011

Economic Analysis Of Continuous Monitoring Of Commercial Truck Tire Pressure Using Tire Pressure Monitoring Systems (Tpms) And Rfid Technologies., Afolabi A. Ogunwemimo

Industrial and Management Systems Engineering -- Dissertations and Student Research

The trucking industry is a major contributor to the US economy. By providing the essential services of transportation and distribution needed in today’s dynamic industry, the transportation industry has evolved into an integral player in various supply chains. The trucking industry is the largest transportation provider for other industries and employs 10.1 million workers in the United States (ATA, 2003).

This research is an analysis of the economic impact of maintaining proper air pressure in the tires of commercial trucks. Various studies have been carried out on understanding the relationship between tire pressure and fuel consumption (National Research ...


Electronic Monitoring Of Hand Hygiene Compliance In An Inpatient Hospital Setting, Christopher M. Masek Nov 2011

Electronic Monitoring Of Hand Hygiene Compliance In An Inpatient Hospital Setting, Christopher M. Masek

Industrial and Management Systems Engineering -- Dissertations and Student Research

Proper hand hygiene is known to reduce hospital acquired infections. Currently the most widely accepted method used to measure hand hygiene compliance is through direct observation. This method often provides data that may not accurately represent true hand hygiene compliance due to such factors such as the Hawthorne Effect. Perhaps a better approach is to use counting devices to capture hand hygiene opportunities and activities. This thesis focuses on the measurement of hand hygiene activities of all individuals that either work or visit an inpatient medical ward including healthcare workers, patients and visitors at the patient’s bedside for non-isolation ...


Influence Of Process Parameters On Health Outcome, Vijaya K. Musunuru Aug 2011

Influence Of Process Parameters On Health Outcome, Vijaya K. Musunuru

Industrial and Management Systems Engineering -- Dissertations and Student Research

In the recent years, healthcare organizations have realized that quality in providing service is critical for their survival in this competitive world. This increased attention to service quality has forced many health care providers to reevaluate their systems to stay in business. The main purpose of this study is to test the hypothesis “Process Quality predicts the Product quality (patient satisfaction) in the healthcare domain”. The objective of this study was three- fold. The first objective is to analyze historical data both on patient satisfaction and on provider attributes to yield process parameters for a particular area in a hospital ...


Investigation Of Rfid Readability For License Plates In Static And Motion Testing, Srinivasan Venkatesan Jul 2011

Investigation Of Rfid Readability For License Plates In Static And Motion Testing, Srinivasan Venkatesan

Industrial and Management Systems Engineering -- Dissertations and Student Research

The most important function of RFID in vehicle tracking is to store information concerning tagged elements in order to improve the overall performance of movable asset management. There is a need to discover an RFID system for the tracking of vehicles, as existing vehicle tracking systems are undependable. Experiments were performed with SIRIT, SAVI, and RF code RFID systems under differing conditions, attaching the tag to the license plate instead of the windshield. Different spacers were also tested to reduce the effect of metal surfaces on RFID signals.

Preliminary experiments were performed before stationary and motion testing in order to ...


Integration Of A Real Option Of An Environmental Project, Qi Yang Jul 2011

Integration Of A Real Option Of An Environmental Project, Qi Yang

Industrial and Management Systems Engineering -- Dissertations and Student Research

This thesis explores a problem of how to evaluate environmental projects under the Carbon Cap-and-Trade Scheme (CCTS) from the perspective of an individual firm. The focus is the integration of a real option approach for project investment timing and financial carbon option approach for carbon credit management. The real option is for a mid or long term decision on when to invest on the environmental project, and the financial option is for a supplementary decision to hedge short-term residue risks. Two uncertainties (the carbon price and carbon credit demand) are considered, and their changes are represented by a lattice of ...


A Study On Facility Planning Using Discrete Event Simulation: Case Study Of A Grain Delivery Terminal., Sarah M. Asio Jul 2011

A Study On Facility Planning Using Discrete Event Simulation: Case Study Of A Grain Delivery Terminal., Sarah M. Asio

Industrial and Management Systems Engineering -- Dissertations and Student Research

The application of traditional approaches to the design of efficient facilities can be tedious and time consuming when uncertainty and a number of constraints exist. Queuing models and mathematical programming techniques are not able to capture the complex interaction between resources, the environment and space constraints for dynamic stochastic processes. In the following study discrete event simulation is applied to the facility planning process for a grain delivery terminal. The discrete event simulation approach has been applied to studies such as capacity planning and facility layout for a gasoline station and evaluating the resource requirements for a manufacturing facility. To ...
