Digital twins of objects in the solution of control problems

Abstract

The paper includes the development analysis for digital representation of objects and processes in the field of production. Authors pay special attention to a description of digital twins (DT) as a key element in a structure of digital transformation tools for production management. The narration covers creation of DT and their groups with known techniques for entity conceptual simulation. There are the new approaches shown as to pressing problems in the comprehensive assessment of a state and administration of production facility’s functioning using digital twins. The considered approaches relate to the comprehensive assessment of an object’s state at any time (in the past, present, future) throughout its life cycle. Authors show that to solve tasks in digital transformation of production processes and management of complex industrial facilities, it makes sense to use the indicators proposed in the paper: system’s internal propensity towards conflicts, its update potential and remaining lifetime. Besides, they conclude that a qualitative analysis of a real entity’s behaviour and its control based on the DT model involve collection and accumulation of all of the available historical data about it, which, in turn, necessitates the creation of special-purpose software for big data processing that support the multidimensional temporal model for organisation of integrated information storages.

Developing a knowledge-based system for the design of innovative product creation processes for network enterprises

“…The development of the concept of dynamic maintenance of information about the state of project decisions regarding the product being developed at various stages of the product life cycle is a concept that is characterized by "the use of integrated information stores, which include, in addition to collecting and analyzing primary data, tools for object representation of the domain in the form of collections of digital twins (DTC) with a description of the structure, composition of objects, their properties, as well as known relationships between them. Promising technologies for organizing integrated information storage should also include methods for their systematic description (construction) and logical and analytical processing" [4].…”

“…The solution of the problem of integrated representation of knowledge about a product and related business processes is currently based on a model-oriented approach to building systems and enterprises [2,3], the implementation of the concept of digital twins [4], as well as the concept of dynamic maintenance of product models at all stages of the lifecycle -the concept of a digital thread [5,6]. Semantic integrity and consistency of information sources used (semantic interoperability) is studied in works related to the construction of ontologies of enterprises [7,8].…”

Creating a Digital Twin to the Online Promotion Process for Small Businesses

“…The Ontology (O) in relation to the online promotion process under study consists of a set of ontologies and has the form: O= {W, Y, X, V, M}, where W is the ontology of the matrix of the targets, Ystrategies ontology, X ontology SEO-nucleus, V-ontology recommendations, M-ontology comparisons. Using software products for managing intellectual space, the ontological model is digitized [17] and digital twin is formed [18]. The interface of the virtual copy concept is shown in Figure 3.…”

Electric heater mathematical model for cyber-physical systems

“…While designing cyber-physical systems, it is necessary to solve a variety of interrelated problems. One of the important tasks is the development of real object's digital twin based on mathematical modeling [2,3]. A digital twin is a digital model obtained based on information from sensors installed on a physical object, which allows you to simulate object's behavior in the real world.…”
