The Evolution of Digital Twins: Essential Skills for Simulating Real-World Systems

The concept of digital twins has rapidly evolved from a theoretical framework to a practical tool used across various industries. A digital twin is essentially a virtual representation of a physical object or system, allowing for real-time simulation and analysis. This article delves into the evolution of digital twins, the essential skills required for their effective implementation, and how they can transform industries by simulating real-world systems.

The Genesis of Digital Twins

The term digital twin was first coined by Dr. Michael Grieves at the University of Michigan in 2002 as part of a product lifecycle management strategy. Initially, digital twins were used primarily in manufacturing sectors where they could help in design and development processes. For example, General Electric employed digital twins to mirror their jet engines, enabling engineers to analyze performance data and optimize operations.
