Analysis Of Safety Decision-Making Data Using Event Tree Analysis, Gretchen A. Mosher, Nir Keren Nov 2011

Analysis Of Safety Decision-Making Data Using Event Tree Analysis, Gretchen A. Mosher, Nir Keren

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Predicting and analyzing employee safety decision-making is an important component of managing safety in the workplace. This presentation will discuss the process of transforming existing safety decisionmaking data into an event tree pathway. Event tree analysis methodology is utilized to identify contributing factors in complex systems, illustrate interrelationships of the causes of specified events, and to quantify probabilities of occurrence for each pathway of events. Once pathways are constructed and probabilities for each are estimated, safety decision paths with the highest probabilities can be targeted for educational intervention. Thus, the use of safety decision-making data with event tree analysis has ...


Measuring The Relationship Between Employee Trust And Quality Decision-Making, Gretchen A. Mosher Nov 2011

Measuring The Relationship Between Employee Trust And Quality Decision-Making, Gretchen A. Mosher

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Quality is one of several workplace goals and several factors influence the quality climate of an organization. One factor believed to play a role in quality climate is trust. Although limited research has examined the relationship between trust and quality climate, no previous inquiry has examined the role worker trust levels play in quality-related decision-making in a workplace setting. Because workplace quality outcomes depend heavily on the decisions made by employees, an understanding of the factors which influence the decisionmaking process of employees is an important component of workplace quality initiatives.


An Optimization Approach To Assessing The Self-Sustainability Potential Of Food Demand In The Midwestern United States, Guiping Hu, Lizhi Wang, Susan W. Arendt, Randy Boeckenstedt Oct 2011

An Optimization Approach To Assessing The Self-Sustainability Potential Of Food Demand In The Midwestern United States, Guiping Hu, Lizhi Wang, Susan W. Arendt, Randy Boeckenstedt

Apparel, Events and Hospitality Management Publications

Conventional agriculture faces significant challenges as world population grows, food demand increases, and mobility becomes increasingly constrained. Reducing the distance food needs to travel is an important goal of sustainability and resiliency, particularly in the context of a variety of transportation challenges. In this study, we developed a linear programming optimization method to assess the potential of regions to meet dietary requirements with more localized and diversified agricultural systems. Emphasis is on minimizing the distance between population centers and available cropland, accounting for variations in yield among 40 of the most marketable food crops that can be grown in the ...


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 ...


Medial Longitudinal Arch Deformation During Walking And Stair Navigation While Carrying Loads, Elizabeth Rose Hageman, Michelle Hall, Eric Gerard Sterner, Gary A. Mirka Jan 2011

Medial Longitudinal Arch Deformation During Walking And Stair Navigation While Carrying Loads, Elizabeth Rose Hageman, Michelle Hall, Eric Gerard Sterner, Gary A. Mirka

Industrial and Manufacturing Systems Engineering Publications

Background:

Understanding the biomechanics of the medial longitudinal arch (MLA) may provide insights into injury risk and prevention, as well as function of the arch-supporting structures. Our understanding of MLA deformation is currently limited to sit-to-stand, walking, and running.

Material and Methods:

Three-dimensional deformation of the MLA of the right foot was characterized in 17 healthy participants during several simulated activities of daily living. MLA deformation was quantified by both changes in arch length and navicular displacement during the stance phase of three motions: walking, stair ascent, and stair descent. Three levels of load were also evaluated: no load, a ...
