A SIMPLE INFERENCE TECHNIQUE FOR DEALING WITH UNCERTAIN FACTS IN TERMS OF POSSIBILITY

In this paper a new approach is proposed for dealing with uncertainty in reasoning. A numerical quantification based on possibility theory is used in the representation of uncertain facts or rules. The chaining of uncertain rules and the combination of results obtained from different chains of inference, are discussed at length. Only min or max operations are used in the chaining and in the combining processes for computing the possibility degrees corresponding to the different alternatives. Partial similarities with other approaches are pointed out.
