Abstract:
1. A method for fuzzy logic control, said method comprising: an input module receiving a precisiated proposition associated with a protoform; a fuzzy logic inference engine evaluating a first fuzzy logic rule from a fuzzy logic rule repository; wherein said fuzzy logic inference engine is in or loaded on or executed on or implemented in a computing device; wherein said computing device comprises one or more of following: computer, processor device, integrated circuit, microprocessor, or server; wherein said fuzzy logic rule repository comprises one or more fuzzy logic rules; wherein said first fuzzy logic rule comprises an antecedent part and a consequent part; wherein said precisiated proposition comprises a Z-valuation; wherein said Z-valuation is in a form of ordered triple (X, A, B), representing a statement assignment of X to a pair (A, B); wherein X represents a variable, A is a fuzzy logic set in domain of X, and B is a fuzzy logic set representing a certainty indicator of X being possiblistically restricted by said fuzzy logic set A; and said evaluating step comprises: a test score evaluation module assigning a first test score to a candidate probability distribution for X based on said Z-valuation; wherein said candidate probability distribution belongs to a set of candidate probability distributions; said test score evaluation module assigning a second test score to said antecedent part based on said antecedent part, said set of candidate probability distributions, and said first test score; and said fuzzy logic inference engine determining whether said antecedent part is satisfied beyond a threshold, based on said second test score.
