The purpose of the study is to analyze the available methods for assessing resources in the economy and identify the most promising ones. Particular attention is paid to the processing of large amounts of information, automation of clustering and interpretation of the results obtained. Scientific novelty: the authors analyzed the advantages and disadvantages of using mathematical methods in economic analysis. As a result, the method of neural network cluster analysis was identified, which has the greatest advantages for economic analysis. Examples of the use of neural network methods in the tasks of financial analysis and risk assessment are given. The results of the work demonstrate the effectiveness of neural network approaches in comparison with traditional statistical methods. The article discusses the prospects for the further use of neural network cluster analysis in the economic sphere. The authors come to the conclusion that the use of mathematical methods in economic analysis provides an opportunity to significantly expand the toolkit for conducting research.
