This paper suggests a way of measuring the strength of an implication to evaluate the influence of the financing structure chosen by company on its efficiency and profitability. The first part describes the semantics of the fuzzy implication applied to continuous variables. The results of three single implication measurements between two criteria are then analyzed on a sample population of 140 companies.

Keywords: Fuzzy implication, Fuzzy logic
