Integrated Planning For Rural Rail Transportation, Jeffrey Cohan Gwaltney
Integrated Planning For Rural Rail Transportation, Jeffrey Cohan Gwaltney
Graduate Theses and Dissertations
Population growth in rural areas has led to new interest in rail transportation. Planning a passenger rail system involves numerous difficult decisions, most representing a trade-off between customer service and cost. In this work, we attempt to integrate many of these planning decisions. We consider strategic decisions such as station location and vehicle procurement, as well as tactical issues that include vehicle scheduling. Our integrated model exploits the linear network structure that best suits many rural American communities, including Northwest Arkansas. Due to the intractability of the integrated rail planning problem, we have developed a customized heuristic approach to solve …
Partial Budgeting Analysis Of Conventional Pump Over Versus Pulsair Cap Management System For A Large–Scale California Winery, Zachary Thomas Hicks
Partial Budgeting Analysis Of Conventional Pump Over Versus Pulsair Cap Management System For A Large–Scale California Winery, Zachary Thomas Hicks
Agribusiness
The purpose of this project was to evaluate the financial feasibility of implementing an automated gas injection system from Pulsair as an alternative to the traditional pump over cap mixing technique that is used during the alcoholic fermentation stage of winemaking.
There were various costs involved in this project that were determined and explained through the use of the partial budgeting method. The costs that were thoroughly analyzed included equipment, labor, utility, and initial investment costs for the Pulsair system as well as the related pump over operation costs. After the two methods associated numbers were evaluated, they were then …
The Fresh Express Lean Changeover Project, Mario Borbas
The Fresh Express Lean Changeover Project, Mario Borbas
Industrial Technology and Packaging
In the current economic turmoil, industry leaders across the globe are resorting to means of increasing efficiency without having a large initial investment. Lean manufacturing principles have been adopted by companies because of its ability to increase throughput, lower overhead, reduce waste, and increase the overall quality of products. The value of lean manufacturing solutions has been increasing in the past decade and continues to increase into 2011.
This project is centered on a current situation regarding a changeover process that has recently been made more efficient. The goal is to create new ways to make this same process even …
Material Weight Station Optimization Senior Project, Douglas Peters, Michael Eng
Material Weight Station Optimization Senior Project, Douglas Peters, Michael Eng
Industrial Technology and Packaging
The main principle of all industry is that “time is money”. This senior project focuses on reducing operation times for Specialty Silicone Fabricators (SSFab) materials weighing station. Currently SSFab is set up so that multiple operators check the weights of materials. This is done to guarantee the accuracy of the readings and maintain tight quality control. This project will focus on eliminating the need of multiple weight checkers as a way to save time and ultimately save money.
Through detailed research and studies it has been determined that the most appropriate solution to this problem is a weight checking software …
Gauge Repeatability And Reproducibility Study For A Bulge Test Fixture For Corrugated Boxes, Anthony J. Hall
Gauge Repeatability And Reproducibility Study For A Bulge Test Fixture For Corrugated Boxes, Anthony J. Hall
Industrial Technology and Packaging
This senior project evaluates the measurement variation within a corrugated container bulge tester by utilizing a gauge repeatability and reproducibility study. Bulge is a type of deformation containers experience when subject to compressive forces such as stacking or internal forces due to under- and over-packaging. Both compressive and internal forces can accelerate the failure of a container by causing panels to flex and flutes to buckle, compromising structural integrity. Additionally, variable environmental conditions such as temperature and humidity can magnify the effect bulge has on a container, speeding up the failure rate of a container.
An Occupational Analysis Of Prepress In The Des Moines And Eastern Iowa Regions, Lee John Geisinger
An Occupational Analysis Of Prepress In The Des Moines And Eastern Iowa Regions, Lee John Geisinger
Dissertations and Theses @ UNI
It is important that educators use a relevant, up-to-date curriculum when educating on a specific occupation. Job task analysis is an effective way for educators to understand an occupation and provide students with valuable information. This study analyzed prepress technicians' duties and tasks.
This research used the occupational analysis method called the DACUM (Developing a Curriculum) process. The DACUM process uses an expert worker panel to identify the duties and tasks of an occupation. This study found that there are 9 duties and 55 tasks for a prepress technician. After identifying the duties and tasks, the study confirmed those duties …
Virtual Design Verification And Process Improvement Of Composite Sheet Material Products Using Intelligent Finite Element Analysis (Ifea), Sathyanarayanan Narasimhan
Virtual Design Verification And Process Improvement Of Composite Sheet Material Products Using Intelligent Finite Element Analysis (Ifea), Sathyanarayanan Narasimhan
Dissertations
Engineering design decisions influence more than 70% of product costs. Various computational analysis tools such as Finite Element Analysis (FEA) are typically utilized, to achieve an effective design cycle. Literature review in design process indicates a striking reality that about 75% of design errors can be eliminated through analysis and about 20% of analyses are misrepresented, leading to inadequate or faulty design. Also, analyses in general, generate more information about the problem than is often looked into, leading to a vast potential to study the knowledge creation.
This research bridges these gaps in design process through efficient use of computer-based …
Quality Costing Knowledge, Attitudes, And Perceptions In A Small Manufacturing Company, Adam M. Benner
Quality Costing Knowledge, Attitudes, And Perceptions In A Small Manufacturing Company, Adam M. Benner
Dissertations and Theses @ UNI
The purpose of this research was to identify and assess employee knowledge, attitude, and perception of quality costing in a manufacturing company. The company selected for this research was a small manufacturer of agricultural processing equipment with an undeveloped quality management program. A quality costs questionnaire was discovered from a review of the literature and was slightly modified to gather data from a sample of company employees. The following information was collected from employees: knowledge of common quality costing terminology, attitude towards quality and non-quality concepts, and perception of departments associated with quality costs and the scale of quality costs …
