Consumer Attention To An Over-The-Counter Warning In Four Different Styles Of Design, Abhishek Gawasane, Laura Bix, Javier De La Fuente, Raghav Prashant Sundar, Timothy J. Smith Nov 2012

Consumer Attention To An Over-The-Counter Warning In Four Different Styles Of Design, Abhishek Gawasane, Laura Bix, Javier De La Fuente, Raghav Prashant Sundar, Timothy J. Smith

Industrial Technology and Packaging

The study consisted of three objectives: (a) to test the relative prominence and conspicuousness of a warning required by US law to be conspicuous; (b) to explore whether or not the conspicuousness of the said warning can be enhanced graphically; and (c) to develop preliminary data for power analysis that would guide decisions related to sample size in future studies.

Seventeen subjects viewed four over-the-counter drug packages (each with a different style of warning) along with five other products while wearing an eye tracking device. Four styles of warning were used on the over-the-counter drug packages: no outline and no …


Assessing Lean Systems Using Variability Mapping, Ahmed Deif May 2012

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 …


Dynamic Analysis Of A Lean Cell Under Uncertainty, Ahmed M. Deif Feb 2012

Dynamic Analysis Of A Lean Cell Under Uncertainty, Ahmed M. Deif

Industrial Technology and Packaging

One of the ultimate targets of lean manufacturing paradigm is to balance production and produce at takt time in production cells. This paper investigates the performance of a lean cell that implements the previous lean goals under uncertainty. The investigation is based on a system dynamics approach to model a dynamic lean cell. Backlog is used as a performance metric that reflects the cell’s responsiveness. The cell performance is compared under certain and uncertain external (demand) and internal (machine availability) conditions. Results showed that although lean cell is expected to be responsive to external demand with minimum waste, however, this …


Measurement And Analysis Of Vehicle Vibration For Delivering Packages In Small‐Sized And Medium‐Sized Trucks And Automobiles, Vanee Chonhenchob, Sher Paul Singh, Jay Jagjit Singh, Joseph Stallings, Gary Grewal Jan 2012

Measurement And Analysis Of Vehicle Vibration For Delivering Packages In Small‐Sized And Medium‐Sized Trucks And Automobiles, Vanee Chonhenchob, Sher Paul Singh, Jay Jagjit Singh, Joseph Stallings, Gary Grewal

Industrial Technology and Packaging

In distribution, packaged products are subjected to the variation in vibration levels from transport vehicles that vary in frequency and acceleration while moving to their destinations. This vibration may negatively affect the product or packaging. This study measured and analysed vibration levels in vehicles commonly used to transport packages in the last leg of the package delivery service that is used by single‐parcel carriers. Using data recorders, we monitored vertical, lateral and longitudinal vibrations over 75 h of travel time in five different types of small and medium package delivery vehicles. The study presents these data as power density (PD) …
