Accounting Information System Reliability

My work on Accounting Information System (AIS) Reliability has been with Krishnan, Jim Peters, and Rema Padman (all great advisors). AIS Reliability is a method used by auditors to first assess the reliability of the AIS, and then to infer the reliability of an organization's financial statements. My work includes building a prototype Decision Support System to aid auditors in the Key Control Selection task, a key step in assessing the reliability of the AIS. The DSS has been implemented, and is now available. The implementation is still a little rough (i.e., you need to know the domain to understand application messages), but it's a nice example of interactive web applications.

Technology's Impact on Cooperative Work

Through both field research and simulation, a group of researchers at Carnegie Mellon's HCI Institute is exploring the impact on cooperative work. My role on this project has been to implement a simulation. The COMIT (Communicating and Information Technology) simulation is capable of simulating hierarchically decomposable maintenance tasks whose precedence can be specified a priori. With additional work, COMIT will be capable of simulating an entire organization. Some pictures of the wearable we use to collect data are on line, check 'em out! Perhaps I'll get around to making the simulation web-accessible some day ...

Man is this OLD!

This is way old and not updated. I am working on links to STAR, the program I wrote to demonstrate that the concepts in my thesis worked. It's a multi-agent modeling and simulation system. I wrote it on the Mac in about 40K lines of code. It's GUI is passable, but it needs some work. Come back another time and maybe you will be lucky enough to see the entire STAR web site ... assuming I get it up and running. Meanwhile, what the heck, I'll show you what I have!
