Including Semantics and Probabilistic Uncertainty in Business Rules Using Fuzzy Modeling and Dempster-Shafer Theory

We discuss the role of fuzzy sets in modeling business rules. The technology involved in fuzzy systems modeling is described. We next introduce some ideas from the Dempster-Shafer theory of evidence. We use the Dempster-Shafer framework to provide a machinery for including randomness in the fuzzy systems modeling process
