DIGITAL DOUBLES IN MANAGEMENT

Abstract

The work considers some digital models of real devices that have interface means by which the simulated object interacts with the external environment. Such models are called «digital twins». Two types of models used in creation of digital twins are considered. These are time series models and domain models. Domain models use the laws of a given domain. They use mathematical, logical and probabilistic properties inherent in a particular domain. Time series models are universal for various domains and do not depend on the physical nature of variables of a specific series. Such models can be used to predict the behavior of a simulated object. As examples, a delay prediction model in a video traffic control system and a model for recharging batteries of wireless sensor networks are considered.
