A programming method based on the ESC pattern is presented. The relevance of the work is due to the fact that the object-oriented approach is one of the most popular and sought-after ways to develop an information product due to a huge regularly updated selection of various methods, templates and ways of its implementation. The most significant of them is Entity System Component (ESC). This method of implementing OOP allows you to make the software product flexible and extensible. The ESC pattern is based on the reactive programming method and divides the entire code architecture into three components: entity, system, component. The tool package that implements the ESC pattern is the ESC DOTS package, designed for the Unity3D environment. The built-in Jobs System package provides the ability to work with multi-threaded programming in Unity. This package distributes threads created at runtime into groups of a certain type, which have a strictly limited execution time. Thus, the task of enumerating an array of several hundred elements goes into a Temp type thread, which runs for one frame in Unity, and the enumeration of a million polygons of the Unity landscape is placed in a Persistent type thread, which has an unlimited time limit.

The algorithm and code listing of the developed self-learning chatbot are presented. Able to maintain a conversation with the user, switch to training mode in the absence of the necessary information, analyze the context of the conversation for "forbidden" words. The Trim function is used, which removes extraneous characters represented in the tr property. And also an additional option "Solve arithmetic problems" is implemented in case of a request from the user. When implementing the latter option, a recursive descent algorithm based on three nested recursive functions was used, while the binary tree is filled in. A function has been developed to divide the incoming string into tokens. The chatbot code is developed in C++/C# based on the principles of object-oriented programming with the development of classes.

The article describes the architectural techniques used in the process of developing case studies for assessing the professional skills of students, implemented as part of the educational process of the RSTU. The decision to use the interface as the center of architecture is justified. Possible problems in the process of developing the interface of the specified software are described, and ways of solving them are also presented. Thanks to the presented methods of building the project architecture, you can get rid of the main drawbacks associated with the dependence of the program code of the implemented product on the user interface. Increase the scalability and reliability of the application, while maintaining the overall quality and functionality.

The virtual simulator of the car inspector is considered. A distinctive feature of this project is that a visual programming editor was developed specifically for this simulator with a set of necessary functionality for developing other virtual simulators. The editor is designed for the Unity3D engine . The editor's functionality has been scaled and expanded, and new vertexes have been added to the developed system. The animation processing algorithm was used and new classes were created. The resulting vertexes are combined into a chain and their performance is checked.

An algorithm for generating and calculating a cargo plan for the Annenkov ferry is described. On the basis of data from the automated control system for the operation of the Caucasus station of the North Caucasian Railway, a software application is being developed that allows to automate the process of drawing up a freight plan. It is proposed to upgrade the existing process of sorting in the process of following the composition in the cargo port
