A continuous real-time expert system for computer operations

The Yorktown Expert System/MVS Manager (or YES/MVS for short) is a continuous real-time expert system that exerts active control over a computing system and provides advice to computer operators. YES/MVS provides advice on routine operations and detects, diagnoses, and responds to problems in the computer operators domain. This paper discusses the YES/MVS system, its domain of application, and issues that arise in the design and development of an expert system that runs continuously in real time.

A New Class of Algorithms for Multipoint Network Optimization

A class of second-order greedy algorithms (SOGA) for the optimization of multipoint networks is defined that is capable of generating improved solutions to problems by an average of more than two percent, relative to the solutions generated by the Esau-Williams algorithm. These SOGA utilize repeated calls of a modified Esau-Williams procedure. They consequently take much longer to execute than does the Esau-Williams algorithm. Nevertheless, problems involving up to 400 points can be solved on a large computer, and 200-point problems can be solved on machines of intermediate size.

An experiment in constructing an open expert system using a knowledge substrate

This paper discusses an experiment in the use of an object-centered knowledge representation service to provide a common conceptual model for the construction of a large knowledge-intensive decision support tool. A core knowledge substrate forms a common resource for a variety of problem-solving activities and a basis for the rapid construction of new capabilities. FAME, a substantial expert system to aid in the financial marketing of IBM mainframes, has been built and extensively tested in the field to validate our tools and techniques.
