Abstract
A new domain in software problem determination can be automated by means of this knowledge-based system. The system imitates a human problem solver by using the same tools and the same diagnostic approach as the experts use, including the processing of human-readable data. The application is fully integrated within the target Multiple Virtual Storage (MVS) operating system to ensure user acceptance. A large variety of knowledge is contained in the system, ranging from pattern-recognition knowledge to basic MVS knowledge and problem-solving strategies. The diagnostic approach is based on a model of software problem situations and on diagnostic reasoning methods adopted from the medical application domain. The goal of the project was to solve a significant part of the problem resolution process automatically, rather than to build yet another tool for use in software problem determination. This system is a first step to further automation in this area.
