Economic aspects of building cyber-physical systems using digital twin systems

The subject of consideration in this article is the principles and metrics for evaluating the economic and qualitative components of cyber-physical systems (CPS) based on digital threads (DTh). Existing methods of estimating cost of the software are considered, and comparative evaluation of these methods is given (advantages/disadvantages/application, as well as depending on the characteristics of the system). The potential gains and additional costs associated with the use of DTh, created on the basis of run-time digital twins, in CPS, are given. Economic model of such a system is proposed. Quality indicators of CPS based on DTh are considered: a general approach to the construction of metric systems is formulated and the quality indicators of the CPS, the observed system (OS), which is part of the CPS, and DTh, which is a tool for the interaction of stakeholders with OS, are considered. A classification scheme for the DTh metrics is constructed and can be classified into groups: application level, evaluation object level of detail, JDL-model level, aspects and usage.
