Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

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 great potential for use in the discipline of safety management.
