Recent Improvements in document image systems and their low-cost implementation on networks of microcomputers is leading to the reengineering of many information systems. We describe how document image systems can be applied to information systems. In order to compare the performance of a conventional information system with one implemented with document imaging processing capability we conducted a discrete event simulation. We modeled the conventional information system for processing graduate student admissions. Then we modeled the system assuming the availability of an. image document capability. The results of 10 simulation runs for each condition indicated that the document image system resulted in faster processing times for graduate student applications and reduced time to answer faculty and student inquires.
