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.

The article is devoted to the development of models and algorithms for calculating control (advisory) actions when training operators of technological processes (on the example of reloading processes and, in particular, portal cranes) on computer training complexes (CTC). A complex of models and algorithms is proposed, based on which control actions are calculated regarding discrete crane controls and the possibility of moving the load to a target position with minimization of oscillations at the end point is provided. These models and algorithms use variable parameters of the technological process, described by linguistic variables, and customizable characteristics of crane models and engines, which allows calculating control actions depending on the type of crane, the specifics of the technological process, the training methodology used for operators and other significant factors. Application of the advisory system based on the developed models and algorithms promotes to improve the training process for operators of reloading cranes at CTC and, as a result, to reduce the probability of emergency situations, reduce time and energy costs.

"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. "

The problem of increasing the efficiency of compiling test plans when testing complex software systems is considered. Automation tools for the development of test plans allow us to describe this document in a rather generalized way, without taking into account many of the attributes required for the success of the further stages of testing the software systems. The use of the developed automated system (AS), described in the article, allows to reduce the complexity of creating test plans due to the presence of a clear sequence of steps in the preparation of the document, providing the specialist with background information and advising effects. In the future, this AS can be used both directly in the development of test plans in the course of real software projects, and in training novice specialists in the skills of filling out these documents.
