  Abstract ▼

  Information-computational systems play a key role in processing and analyzing large amounts of data, ensuring the efficient functioning of production, provision, as well as receipt of various digital goods and services. In the conditions of intellectualization and increasing diversity of functional requirements imposed on information systems, there is a need to develop new approaches for their construction and implementation. The paper considers the main features of the proposed agent-modular approach, which involves the construction of flexible and scalable information-computational systems capable of functioning in a distributed environment. The agent-modular approach is a methodological approach to the organization of information-computational systems based on the integration of system analysis methods, as well as agent and modular principle's of building various systems. The aim of the paper is to investigate theoretical and practical aspects of the application of the proposed agent-modular approach in building an information system, to analyze its advantages over other common approaches (object, component, service), and to present examples of its successful use. To achieve the set goal, it is necessary to solve the following tasks: – to research the theoretical foundations and identify the specific features of practical application of the proposed agent-modular approach; – to analyze the differences and describe the advantages of the proposed approach in its comparison with other approaches; – to present an example of building an information-computational system using the proposed approach. The following general scientific methods were used in the research process: decomposition, analysis, synthesis, comparison, description, formalization, structurization, modeling, design, as well as the basic principles of system, modular and agent-based approaches. Computers, and computing software tools were used as research materials. As a result of the study, the main theoretical and practical aspects of the proposed approach were considered. The agent-modular approach can be used to build various information systems at the stages related to their modeling and design. The proposed approach allows describing the structure, functioning, and interaction of various components of information-computational systems.

  Abstract ▼

  The article presents the development results of a module for the retail network mobile application
  modernization. A feature of the presented mobile application module is the display of personalized
  messages with advertising and promotions of the retail network. A mathematical model
  of machine learning is used to collect and analyze data in a mobile application. The process ofchoosing a mathematical model, the operation algorithm and the model training stages on training
  data are described in detail. The quality of the classifier's work was evaluated on a test and training
  sample. Test sample objects classification and the real value of the class comparison with the resulting
  classification were performed. The authors in the article presented the main stages of the algorithms
  development for processing statistical data from customer receipts. The program codes for the
  receipt analysis module implementation and display the mobile application personalized advertising
  are presented. To implement the database as a tool, the authors used the relational data management
  system MS SQL Server. The modules of the mobile application are developed in the Android Studio
  environment for the Android operating system family. The authors presented the algorithm main
  stages and testing the implemented modules operability in the paper. Based on the data on purchases
  made by the buyer, information about preferred products is collected based on the fixation of product
  groups and product items from the receipt. The loyalty card of the retail network is linked to the mobile
  application, and receipts for purchases are linked to loyalty cards, in turn. Previously, the application
  displayed ads for all products participating in promotions. The actual task is to display personalized
  advertising, which has proven its effectiveness. The mobile application is distributed for
  free through the Play Market and is designed for smartphones running the Android OS line.
  The purpose of the development is to display in the application on the buyer's device first advertising
  frequently purchased goods, and then the rest of the promotional goods. The mobile application has
  passed load testing in real use by customers conditions of the retail network.
