A digital twin is primarily used in industries for simulation and analysis of real-world systems or processes. By creating a virtual replica of physical assets, machines, or systems, industries can monitor performance, predict failures, and optimize operations. This technology allows for real-time data collection and analysis, aiding in maintenance and improving efficiency. In sectors such as manufacturing, healthcare, or urban planning, digital twins enable companies to test changes in a risk-free environment before implementation, ultimately leading to enhanced productivity and reduced costs.
