Digital Twins of Activities: Role of Information Actions

The article considers concepts and models for digital twins of activities and methods available to use such digital twins. Emphasis is made on modelling of information actions as a part of activity and information use in the activity. Authors show that there is a multidisciplinary gap between the need to model application of information for further activity in systems (when creating digital twin of activity) and available theoretical means for the modelling of application of information while performing activity. Models suggested can be used to create models for digital twin of activity, which represents an information application for activity. As a result, the digital twin of activity, represented by such models, can be used to synthesize activity characteristics and information actions for systems functioning in various conditions. To build models required, diagrammatic models of information application for activity in systems are suggested. Diagrammatic models suggested can be used for further creation of new formal models of activity and formal models of information technologies applications to fulfill successful activity. Suggested models can be applied to build digital twins of the activity. Such twins allow representing and, then, enhancing activity based on information collected and to enhance information application for activity. This could further allow us to solve problems related to digital transformation planning of various activities, system engineering problems, computer aided design and manufacture problems, information activities synthesis problems.
