Advances in technology make it possible for the EDP auditor to work smarter, faster, and deliver added value on every audit. In part this is true because the commoditization of computer hardware...
Issues in Model Based Troubleshooting, (1998)
Hamscher,Walter, Davis,Randall
To determine why something has stopped working, it's helpful to know how it was supposed to work in the first place. This simple fact underlies recent work on a number of systems that do diagnosis...
Model-based troubleshooting relies on having a representation of devices that can provide predictions about their behavior based on the observations that the troubleshooter makes. For complex devices...
