Computer Simulation Analysis of the USAF Vehicle Allowance/Authorization Process.

摘要

This research examined the effects of the incorporation of Electronic Data Interchange (EDI) on the USAF vehicle allowance/authorization process. The study utilized a computer simulation model to mimic the flow of the AF form 601, Equipment Action Request, as it is submitted at base level and coordinated through the MAJCOM and WR-ALC. The hypothesis was that the allowance/authorization cycle time could be made shorter by transmitting the information contained on the form 601 electronically, rather than mailing the form to each coordinating agency. In order to compare the process with and without the use of EDI, two computer simulation models were developed, one which reproduced the current system and another whose variables and parameters were modified to simulate the effects of EDI. The output from the models was compared by using a paired-t test to determine differences in average system residence time for the 601. The incorporation of EDI was found to produce modest improvements in 601 residence times--the time elapsed in the coordination process between 601 submittal and approval. Mean residence times were reduced by approximately nine days by transmitting the information electronically. Additionally, it was found that reductions in processing times hinted at even greater reductions in average 601 residence times.
