  • A training system for testing knowledge and skills in the basics of programming in high-level languages

    The article is devoted to the development of training systems for training specialists in automation and informatization. The structure and mathematical model of a training system (TS) were developed to control skills in training these specialists (in particular, in the basics of programming). The parameters of the mathematical model are based on the representation of knowledge about the studied objects and processes in the field of development of automated information systems, which allows using TS to automatically generate and evaluate small practical tasks for students. A prototype of TS software in the form of a web application has been developed. In a practical aspect, the use of TS in the educational process in the disciplines in the field of programming will reduce the proportion of labor-intensive work of the teacher in compiling and checking assignments.

  • Automation of evaluation of operator training efficiency on computer simulators using statistical methods

    "The article is devoted to solving the problem in the field of development of methods and means of automation of evaluation of training efficiency on computer simulators, which are used for the training of operators of production processes. Approaches to assessing the effectiveness of training are given in many scientific studies on the creation and application of computer simulators. However, the problem of automation of the process of this assessment on the basis of the simulators themselves is not sufficiently considered. The evaluation methodology (based on mathematical statistics methods) and the prototype subsystem of the computer simulator complex were proposed to solve the indicated problem. They reduce the effort of the expert responsible for performance evaluation. Output results can be used for training operators in educational organizations. The reported study was funded by RFBR according to the research project № 18-38-00835. "
