Abstract:
1. In a computer-based risk management system utilizing fuzzy logic, a method for generating an indication of risk, said method comprising: a) said system receiving an expert defined rule entered by a user into said risk management system mapping at least one rule input A to at least one rule output B; b) said system receiving a data input A′ and a data output B′ from said user; c) comparing said data input A′ with said rule input A to determine a first degree of mismatch d d) assigning a function M e) using said first degree of mismatch and said function M f) calculating said envelope of possibility B g) calculating an envelope of belief B h) said system receiving additional expert input having at least one assertion G required to be proven true; i) said system receiving an expert defined minimum degree of proof H j) comparing said envelope of belief B k) comparing said required minimum degree of proof H l) said system receiving an expert defined minimum degree of ignorance l m) calculating an actual degree of ignorance l for said assertion G according to a difference between said envelope of belief B n) comparing said minimum degree of ignorance l for said assertion G and said actual degree of ignorance l for said assertion G to generate a second conclusion about an acceptability of said degree of ignorance l for said assertion G; o) said system receiving an expert defined minimum degree of possibility K p) comparing said envelope of possibilities B q) comparing said actual degree of possibility K and said required minimum degree of possibility K r) generating said indication of risk by evaluating said conclusions against said assertion G, said indication of risk indicating whether or not said assertion G is good; and s) said system outputting said indication of risk.
