Abstract:
A fuzzy logic based model assessment system for assessing at least one model of physical phenomena using measurement residual values representing a difference between a measured data sequence corresponding to said physical phenomena and an expected data sequence corresponding to said model to be assessed, said system comprising:a feature identification module for identifying at least one feature present in said measurement residual values, and for generating at least one feature amplitude value and at least one feature amplitude standard deviation value; an anomaly characterization module for characterizing said at least one feature in at least one membership class based upon said at least one feature amplitude value, and for generating class membership interval values for each said at least one membership class based upon said at least one feature amplitude standard deviation value, and wherein said class membership interval values represent a range of degrees of membership in each said at least one membership class; and a hypothesis formulation and evaluation module for determining at least one mismodeling hypothesis by applying fuzzy inferencing to said class membership interval values, and for generating at least one hypothesis certainty value representing a degree of certainty of said at least one mismodeling hypothesis.
