Annotation

The article presents a methodological approach to assessing the investment attractiveness of an enterprise  based on the Hopfield neural network mathematical apparatus. An extended set of evaluation parameters of the investment process has been compiled. An algorithm for formalizing the decision-making process regarding the investment attractiveness of the enterprise based on the mathematical apparatus of neural networks has been developed. The proposed approach allows taking into account the constantly changing sets of quantitative and qualitative parameters, identifying the appropriate level of investment attractiveness of the enterprise with minimal money and time expenses – one of the standards of the Hopfield network, which is most similar to the one that characterizes the activity of the enterprise. Developed complex formalization of the investment process  allows you to make investment decisions in the context of incompleteness and heterogeneity of information, based on the methodological tools of neural networks.

Keywords: Hopfield neural network, investing, estimation parameters, modeling, formalization, output parameters.
