Medical Diagnois using Simplified Multi-dimensional Fuzzy Reasoning

Abstract
This paper proposes a method for computer-assisted medical diagnosis using simplified multi-dimensional fuzzy reasoning. The reasoning is based on the iterative use of fuzzy modus ponens and fuzzy modus tollens. Seven types of easy-to-gather production rules for fuzzy medical diagnosis are proposed. The fuzzy inference mechanism accepts patient's symptoms with attached degree of compatibility and infers diagnoses with a degree of certainty that expresses the degree to which it can be certain that the diagnosis is correct. Truthfulness of relationships between symptoms and diseases are fuzzily expressed in terms of linguistic truth values such as "Very True" and "Possibly True". Practical methods for the examination of unconfirmed symptoms and for the reexamination of given symptoms are also considered.
