Probability based expert systems
Webb25 sep. 1994 · The expert system consists of a series of "if-then" rules that describe the relationship between observed complications and their potential causes. Diagnostic uncertainty is treated by Bayesian statistics and each potential cause is stated with an associated probability according to the signs and symptoms identified by the user.

In the framework of the VBS, belief functions can be used to interpret and combine uncertain information. The VBS has already been used to represent and propagate different types of uncertainties in the literature.
