The Effect Of Stretch Wrap Pre-Stretch On Unitized Load Containment, Evan A. Cernokus

Master's Theses

There are three main factors affecting the stability of a palletized load that is unitized by a stretch wrapping mechanism. These factors include the type of unitized load, wrapping configuration and shipping method. The wrapping configuration is determined on the basis of the type of unitized load and shipping method. For this study, the aforementioned components were referred to as the package, the product, and the distribution environment. These components come together to make up a stretch wrapping system. The package corresponds to the stretch wrap film that is packaging the unitized load and pallet. The product corresponds to the …

Optimization Models And Algorithms For Truckload Relay Network Design, Hector Andres Vergara Arteaga

Graduate Theses and Dissertations

Driver turnover is a significant problem for full truckload (TL) carriers that operate using point-to-point (PtP) dispatching. The low quality of life of drivers due to the long periods of time they spend away from home is usually identified as one of the main reasons for the high turnover. In contrast, driver turnover is not as significant for less-than-truckload (LTL) carriers that use hub-and-spoke transportation networks which allow drivers to return home more frequently. Based on the differences between TL and LTL, the use of a relay network (RN) has been proposed as an alternative dispatching method for TL transportation …

Assessing Lean Systems Using Variability Mapping, Ahmed Deif

Industrial Technology and Packaging

A new approach to assess lean manufacturing based on system's variability is proposed. The assessment utilizes a new tool called variability source mapping (VSMII) which focuses on capturing and reducing variability across the production system. The new tool offers a new metric called variability index to measure the overall variability level of the system. Based on the mapping and the new metric, VSMII suggests a variability reduction plan guided by a recommendation list of both lean techniques as well as production control policies. An industrial application is used to demonstrate the new tool. Results show that VSMII managed to reduce …

A Phenomenological Study Of Professional Identity Change In Released-Time Seminary Teachers, Mark Daniel Mason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many practitioners commonly deal with implementing a change that is imposed by an organization. Some imposed changes require practitioners to alter more than what they do in practice but also to change their identity. Many researchers have studied identity change through the lens of sociocultural theory, specifically utilizing communities of practice theory (CoP). However, the majority of these studies used CoP theory as a vehicle to implement the imposed change. Yet some studies have found that after the trial period ends many practitioners revert back to the way they performed in practice prior to the study. One reason for this …

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 …

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 Exploratory Model For Predicting Post-Consumer Recycled Pet Content In Pet Sheets, Dong Ho Kang, Rafael Auras, Keith Vorst, Jay Singh

Industrial Technology and Packaging

An exploratory model for determining post-consumer recycled polyethylene terephthalate (PET) content in PET sheets for one specific stream of mechanically recycled PET (RPET) was developed. Six kinds of PET sheets with varying percent of virgin (V) and recycled (R) PET contents (i.e., 100V, 80V20R, 60V40R, 40V60R, 20V80R, and 100R PET) were commercially extruded. The optical, thermal, physicomechanical and barrier properties of the PET sheets were evaluated as function of RPET content. Differences were found between the sheets for UV and visible light absorption in the regions 200–350 nm and 670–700 nm, respectively. Intrinsic viscosities of 100V and 100R PET sheets …
