DIGITAL TWINS
INTRODUCTION
A digital twin is a virtual model of a physical object or system that uses real-time data to simulate its behavior. Digital twins can be used to understand how a physical object works, monitor its performance, and identify potential issues.
How do digital twins work?
- Data sources: Digital twins are linked to real-world data sources, such as sensors on the physical object.
- Real-time updates: The digital twin updates in real time to reflect any changes to the physical object.
- Behavioral insights: Digital twins can include visualizations and insights derived from data.
ADVATAGES AND DISADVANTAGES OF DIGITAL TWINS:
Digital twin technology has many advantages, including improved efficiency and decision-making, but it also has some disadvantages.
