Modeling And Analysis Of Pca Workflow, Ewing Tiong
Modeling And Analysis Of Pca Workflow, Ewing Tiong
Masters Theses
Nursing shortage has been reported as a major problem faced not only by the United States but also by many other countries. One of the many interventions that has been used to curb nursing shortage is the increase in employment of Unlicensed Assistive Personnels (UAPs) as an alternative care delivery model. There are many types of UAP and one of them are Patient Care Assistants (PCAs). This research proposes a methodology to model and analyze the work ow of a PCA in terms of completing assigned tasks in a timely manner. The specific objectives of this research are to model …
Truckload Carrier Selection, Routing And Cost Optimization, Zhixin Han
Truckload Carrier Selection, Routing And Cost Optimization, Zhixin Han
Masters Theses
The aim of this thesis was to investigate the routing decision combined with common carrier selection for dedicated contract carriers to reduce full truckload routing cost on pickup and delivery service within time windows in a multiple depots scenario. Mixed Integer Programming and some heuristic algorithms such as the genetic algorithm and annealing algorithm have been successfully used to solve vehicle routing problems for a long time, but researchers seldom simultaneously focus on issues of carrier selection, multiple depots, time window, and the government regulations for a dedicated contract carrier. Therefore, this thesis involved constraints of pickup and delivery with …
Heuristic Solution For Separated Manufacturing Process, James Dee Davis
Heuristic Solution For Separated Manufacturing Process, James Dee Davis
Masters Theses
Downtime is a major issue for manufactures. Downtime may occur from breakdowns, quality issues, lack of manpower, lack of materials, or in this case a lack of storage containers. A manufacturing system was studied that consists of an injection machine that supplies two assembly lines. The injection machine suffered from frequent downtime from lack of containers. The process was analyzed for root cause of downtime. After analysis of the system it was found that the injection process had high variability in production quantity and quality. The scheduling scheme called for production until all available containers were full regardless of actual …
Evaluation Of A Training Program (Strap) Designed To Decrease Young Drivers Secondary Task Engagement In High Risk Scenarios, Akhilesh Krishnan
Evaluation Of A Training Program (Strap) Designed To Decrease Young Drivers Secondary Task Engagement In High Risk Scenarios, Akhilesh Krishnan
Masters Theses
Distracted driving involving secondary tasks is known to lead to an increased likelihood of being involved in motor vehicle crashes. Some secondary tasks are unnecessary and should never be performed. But other secondary tasks, e.g., operating the defroster, are critical to safe driving. Ideally, the driver should schedule when to perform the critical tasks such that the likelihood of a hazard materializing is relatively small during the performance of the secondary task. The current study evaluates a training program -- STRAP (Secondary Task Regulatory & Anticipatory Program) -- which is designed to make drivers aware of latent hazards …
Integration Of Maintenance Into Design And Sustainability Of Buildings, Dinesh Reddy Patlolla
Integration Of Maintenance Into Design And Sustainability Of Buildings, Dinesh Reddy Patlolla
Masters Theses
Custodial maintenance is an important aspect of operational maintenance in a facility. Custodial maintenance improves an organization's discipline, performance and keeps surroundings healthy. That being said maintaining clean surroundings involves considerable cost. Custodial maintenance cost forms significant portion of building budgets, however these costs are often neglected. This research deals with the identification of variables that affect maintenance costs in a facility and reduction of maintenance costs. The minimization of cost is done by giving the administrator or facilities manager the option of selecting alternatives in frequency of maintenance, level of maintenance and the number of people required to complete …
Modelling Supercomputer Maintenance Interrupts: Maintenance Policy Recommendations, Jagadish Cherukuri
Modelling Supercomputer Maintenance Interrupts: Maintenance Policy Recommendations, Jagadish Cherukuri
Masters Theses
A supercomputer is a repairable system with large number of compute nodes interconnected to work in harmony to achieve superior computational performance. Reliability of such a complex system depends on an effective maintenance strategy that involves both emergency and preventive maintenance. This thesis analyzes the maintenance records of four supercomputers operational at The National Institute of Computational Science located at Oak Ridge National Laboratory. We propose to use the generalized proportional intensities model (GPIM) to model the maintenance interrupts as it can capture both the reliability parameters and maintenance parameters and allows the inclusion of both emergency and preventive maintenance. …
Loss On Ignition Using Infrared Heating, Benjamin J. Binoniemi
Loss On Ignition Using Infrared Heating, Benjamin J. Binoniemi
Masters Theses
The focus of this study is a proof of concept that infrared heating can be used to produce a reliable and rapid method of performing the loss on ignition test. The loss on ignition test is a foundry industry standard test that requires all moisture and volatile organic compounds be vaporized from a sample of foundry sand. The standard test as recommended by the American Foundry Society uses a muffle oven and requires nearly four hours to perform. This new concept performs the same test in approximately ten minutes. The biggest issues with the loss on ignition test are time …
Value Stream Segmentation And New Product Development, Richard Lee Vaughn
Value Stream Segmentation And New Product Development, Richard Lee Vaughn
Masters Theses
This research paper expands upon prior research into the pursuit of the successful new product launch. It reviews the evolution of how new product launches were handled in the past and the best practices used today. The article “Value Stream Segmentation Focuses on Customer Needs” expands upon the success and failure of the practices and poses a new concept for future new product launches. The concept of “value stream segmentation” is how a company should use value stream mapping to streamline its processes to achieve a successful new product launch. By analyzing and segmenting market requirements, a business that is …
