ABSTRACT:
An inference engine device adapted for use in a computer-controlled expert system, the computer-controlled expert system having a computer and a knowledge base of objects and rules, the objects having known values and unknown values, the rules having at least one test against an object or objects and configured in a Rete based network. The inference engine is comprised of a first module with a function of storing instructions for the computer; a second module, associated with the first module, that is comprised of a function for instructing the computer to perform forward reasoning with the objects having known values and another function for generating a conflict set; a third module, associated with the first module, that has a function of instructing the computer to perform backward reasoning about the objects having unknown values; and a fourth module, associated with the first module, that determines whether the first or second module is being executed by the computer.
