Knowledge Based DSS

Abstract

“A knowledge based DSS is a computer information system that provides information and methodological knowledge (domain knowledge and decision methodology knowledge) by means of analytical decision models and access to data base and knowledge base to support a decision maker in making decisions in complex and ill structured tasks.” (Klein & Methlie) The conceptual frameworks of knowledge based DSS is the result of the merging of two conceptual frameworks, the DSS framework and the knowledge based framework. These two frameworks were developed in parallel over a period of about 20 years, roughly from 1965 to 1985. We shall briefly recall these two frameworks and then explain why they were merged. The knowledge based DSS framework has since then evolved in its own right, taking into account methodological and technological advances.
