The use of modern achievements of scientific and technological progress is crucial in building information systems and implementing information technologies. Recently, artificial neural networks have been used to solve several data classification and clustering tasks, which allow achieving extraordinary accuracy. The availability of a large number of software and hardware tools for creating and training artificial neural networks, as well as the ability to use a large amount of data (including data from real enterprises) to train networks on it, allows you to quickly build effective models for solving various problems, including economic ones. In today's conditions, tracking and calculating the dynamics of the integral indicator of competitiveness of an e-commerce enterprise is one of the main indicators of the state of the enterprise in the economic space of the state. Accordingly, to calculate and model situations related to the calculation of the dynamics of the integral indicator of competitiveness of an e-commerce enterprise, it is worth applying neural network models for processing and analyzing a large amount of data. This approach allows optimizing enterprise management processes, increasing the personalization of service and ensuring effective interaction with customers, etc. The considered convolutional neural network has such special properties as self-organization, the ability to learn in the process of work, generalization, simulation of processes and phenomena, including nonlinear ones, formation of complex dependencies in the space of diagnostic events, efficiency of work with high-dimensional features, which determine the expediency of their use for solving forecasting problems, in particular, calculation and modeling of situations related to the calculation of the dynamics of the integral indicator of competitiveness of an e-commerce enterprise.

The article identifies basic approaches to modelling information systems of the entity, based on the retrospective processes on the issues of cognitive approach to modelling complex information systems. In the article described approaches of usage of the cognitive modelling apparatus to analyse the financial condition and the efficiency of the entity. Information intellectual decision-making systems are found in applied multi-agent systems, geoinformation systems, economic systems, and systems in which decisions are to be made based on knowledge. One of the elements used to remove information from the knowledge base is cognitive maps and they show the dynamic of the properties of various situations. A cognitive map that reflects a specific situation can be considered as a kind of graphic interpretation of a mathematical model, which clearly reflects the situation and allows for the formalization of the problem to present a complex system as a set of interdependent concepts. Cognitive maps are used to solve problems that are primarily related to the analysis of the existing state of the object and decision-making. Cognitive maps make it possible to establish cause and effect ratios and to form a knowledge base for decision-making. The financial condition of the entity requires modelling of intellectual systems, which is recommended to be based on the combination of methods of system analysis and cognitive modelling. This approach allows you to reliably evaluate the financial condition of the entity, because the basis of the information intellectual system for the decision-making is a mathematical model created on the basis of classical system analysis and cognitive methods. The use of artificial intelligence elements in intellectual management and analytical systems for the analysis of the financial condition of an entity is a modern powerful tool for any country's economic business processes.
