Fundamentals of Digital Twins

Before diving into the specifics, it’s important for you to grasp the essence of digital twins. These virtual models are critical tools that help you simulate, predict, and optimize real-world objects or systems through real-time data and analytics.

Defining Digital Twins

Digital twins are virtual simulations of physical objects or systems. They mirror the real assets with such accuracy that you can visualize, monitor, and test them without interacting with the physical world. This revolutionary technology provides you with a comprehensive digital footprint of your physical assets, allowing for advanced analytics and diagnostics. For instance, the concept of digital twins was formalized by Dr. Michael Grieves in 2002. He proposed them as a mirrored model where every unit in the physical space has a digital counterpart.
