The article analyzes the available theoretical studies on assessing both the financial state and financial stability of an enterprise based on various approaches, including bankruptcy models, simulation modeling, etc. This made it possible for the authors of the article to develop their own mathematical and structural models of the process of assessing the financial state of the enterprise by means of system analysis, as well as its formalization based on the apparatus of fuzzy logic. A set of aggregating functions for summarizing quantitative evaluation parameters describing the financial stability, liquidity and solvency, business activity, and profitability of the enterprise under study is substantiated. Moreover, the mathematical model took into account the company’s business reputation, which is evaluated based on five qualitative parameters, to obtain an accurate resulting decision. The experimental pool of verification of the developed model for assessing the enterprise’s financial state is 15 enterprises.
Keywords: system analysis, mathematical modeling, fuzzy logic, assessing of enterprise’s financial state.
