Knowledge Representation and Inference in Knowledge Based Systems (Expert Systems) usually monotonic and the control is procedural. Second generation KBS usually exhibit nonmonotonic reasoning, declarative control, and more sophisticated representations of uncertainty. We will focus on the first generation KBS and analyze their typical architecture, composed of a Knowledge Base (

First, we will describe the recursive nature of a simple BC, without considering uncertainty. Then, we will extend the definition of the BC to a simple representa

First, is the diagnostic task which requires determining differences between a model of a mechanical structure and the structure itself. The diagnostic procedure should be efficient

A Rule Backward Chainer for Knowledge Based Systems (Expert Systems)ll describe the recursive nature of a simple BC, without considering uncertainty. Then, we will extend the definition of the BC to a simple representation of uncertainty. Finally we will suggest enhancements for more complex versions of the BC.
