Introduction: One of the key deterrents to the quality training of engineers for digital economy is the lack of access to modern
laboratory equipment in Russian regional universities. An effective approach to solving this problem is organizing remote access to
experimental equipment based on the concept of multi-tenancy. Purpose: Developing a method to organize a high-tech digital educational
environment, providing laboratory research in a remote multi-user mode for the training of engineers with contextual learning
technology. Methods: Creating a unified structure for a digital educational environment segment, based on multi-user distributed
measuring-control systems with a unified structure and special methods of adapting such systems to various conditions of their operation.
Results: A unified structure for a digital educational environment segment has been developed and tested. Its main elements are
a web laboratory providing regulated access of trainees to the laboratory studies, and multi-user distributed measuring-control systems
implementing these studies by providing the trainees with parallel access to their shared resources: automated laboratory layouts/
stands/installations. The created software complex for the collection and processing of statistical information about the functioning of
multi-user distributed measuring-control systems as mass service systems underlies the proposed method of their adaptation to various
operating conditions. The proposed segment of digital educational environment allows you to implement a number of contextual training
directions, including: application in experimental research of modern computer measuring technologies; studying the characteristics
of a digital twin of a laboratory layout/installation using standard techniques; identification and verification of mathematical models
of objects, devices, processes and phenomena under study, or samples of multi-user systems in the form of appropriate mass service
systems; approbation of various shared resource dispatch algorithms. Practical relevance: The proposed structure of an educational
environment segment provides training of engineers using innovative hardware and software solutions; operation of experimental
equipment on the basis of multi-tenancy concept, reducing the cost of equipping a trainee workplace in dozens of times; system-level
application of contextual learning technology.
