A new expert system architecture for decision support

Describes Frameworks for Aiding Decisions (FAD), the goal being to provide decision support or to eventually replace the decision maker. FAD consists of three distinct subsystems: the conceptual level, which is the methodological level; the second level, which is for planning and intertool usage; and the local intelligent tools level. The novel aspect of the system is the introduction of a dynamic aspect in the classical knowledge base and a way of verifying consistency and integrity of data. Also presented is a variant of the blackboard architecture, involving the transformation of the triggering agent in the methodological level.<>
