Abstract

Troubleshooting measurement equipment can be complex and time consuming task. We developed a system that incorporates model-based diagnosis to troubleshoot measurement instrumentation systems. It consists of a knowledge representation scheme for modeling the structure and behavior of measurement systems and the ability to reason from first principles about these models. It accepts observed values from the user and returns a list of components that are suspected of failing. The current system was developed using the object oriented approach and was designed to be reusable for a variety of measurement systems. We discuss our expansion of Randy Davis' approach to model-based diagnosis to include instrumentation systems.
