The combined use of Database Management Systems (DBMS)and Artificial Intelligence-based Expert Systems (ES) ispotentially very valuable for modern business applications.The large body of facts usually required in business informationsystems can be made available to an ES through anexisting...

As part of the operation of an Expert System, adeductive component accesses a database of facts to helpsimulate the behavior of a human expert in a particularproblem domain. The nature of this access is examined, andfour access strategies are identified. Features of each ofthese strategies are...

Knowledge bases constitute the core of those Artificial Intelligenceprograms which have come to be known as Expert Systems. Anexamination of the most dominant knowledge representation schemes usedin these systems reveals that a knowledge base can, and possiblyshould, be described at several...

The formulation of complex planning models, such as linearprogramming (LP) systems, is a difficult task that enjoys little supportby current decision support systems tools. It is hypothesized thatcurrent artificial intelligence technology is insufficient to buildgeneralized formulation tools...

Over the last decade there have been several efforts at building knowledge based quot;expertsystemsAtilde;cent;Acirc;not;Acirc;?, mostly in the scientific and medical arenas. Despite the fact that almost all suchsystems are in their experimental stages, designers are optimistic about their eventual...

We present expert system (ES) and Integer Programming (IP) formulations of an NP-completeconstraint satisfaction problem (CSP). The problem involves generating aplan for assigning faculty to courses given a variety of constraints and preferences andother tentative data. The expert system...

This paper addresses the problem of managing the development andimplementation of a large expert system in an organization. A traditionalsystems analysis and design methodology is used as a framework to highlightsimilarities and differences in managing large scale traditional computerbased...
