Dear readers: Contained within the compressed folder labeled "Simulation Model", there are two ARENA model files, ten text files, and two Excel files. The ARENA software program is required to view the ARENA model files. To run the simulation models the text files and Excel files must first be linked to the ARENA model files by means of the "File" data module. The SIMAN code for each of the simulation models are also available in text files. Patrick M. Rappold July 17, 2006
