Abstract
The paper discusses the goals and objectives of creating digital twins of the production system of a machine-building enterprise. The data structure of the information model of the production system of a machine-building enterprise, which is the basis for building a digital twin, is presented. The paper shows the main approaches to managing a production system based on the construction of its digital twin. It is revealed that along with traditional approaches to PS management by forming recommendations in terms of PS engineering and its operation, the choice of the most rational PS management algorithms that take into account the peculiarities of the production process organization and ensure the formation of production schedules that take into account PS reliability indicators has a great potential. It is proposed to use a specialized language of DPML to describe the information model of the PS through the “product-process-resource” paradigm, which ensures the coordination of the processes of forming recommendations in terms of engineering and operation of the PS, as well as the choice of the most rational algorithm for managing the PS.
Highlights
Modern trends in the development of information technologies in the world in recent years are inextricably linked with the emergence of new approaches to the design and organization of production
The digital twin of production system (PS) instance of the machine-building enterprise is developed on the basis of the digital twin of the PS prototype and has additional characteristics: - corresponds to a specific PS; - allows us to diagnose and evaluate the behaviour of the PS based on its model, including statistical data on its work; - contains information about the model settings, control parameters, sensor data and statistics about the operation of the PS
The solution of the problem of effective PS management using its digital twin is based on the task of creating an adequate and consistent information model that defines the requirements for the data structure necessary to solve the corresponding problems, as well as for the composition and interaction of information systems containing and processing this data
