Abstract
A knowledge engineering tool for building expert systems is disclosed. The knowledge engineering tool includes a knowledge base containing 'if-then' rules and an inference engine that includes a plurality of object processors. Each object processor has access to a set of variables defining an object. Rules are selected from the knowledge base and routed to the object processors having access to the objects referenced in the rule. In a parallel processing configuration, each object processor executes on a processing unit and rules are passed as messages.
