A fuzzy logic evaluation system for commercial loan analysis

Abstract

This paper introduces an application of fuzzy logic to commercial loan analysis. It describes the fuzzy sets and linguistic variables that contribute to the financial evaluation. It also presents a computer-based Fuzzy Logic Evaluation System consisting of the components Specify Fuzzy Sets, Edit Rules, and Evaluator. The Evaluator performs fuzzification, evaluation, and defuzzification activities. Using company-specific and industry financial data, the current version of the system appraises a company's credit, capital, and capacity performance. A specific example for efficiency analysis illustrates the system constructs.commercial loan analysis fuzzy logic fuzzy set
