Social Digital Twin Capable of Prior Examination for Cyber Physical Human Systems

Abstract

In Cyber Physical Human Systems (CPHS), multiple systems and people interact with each other. Therefore, in order to develop a system based on CPHS, it is necessary to examine its effects and impacts across different domains, such as transport, economy, and environment. Social Digital Twin (SDT) is a technology that enables such prior examination. By using SDT, it is possible to examine the effects of a system by simulating society, including human behavior to the system, based on real-world data. We have developed a simulation system that integrates heterogeneous simulators for SDT. This paper describes the requirements, configuration, and technical issues of the system.
