Digital Twin- The Next Frontier in IIoT
What is a Digital twin?
The concept of the digital twin was originally proposed in 2002 by Michael Grieves for use in the field of product life cycle management (PLM) and gaining momentum with advancement in IIoT ecosystem. The phrase “Digital Twin” refers to digital replica of any physical object, entity, process, person, or a system contextualized in a digital version of its environment. It is a virtual model designed to reflect the properties and behaviors of the physical object and its environment. Digital twins enable organizations to model real-world scenarios and their outcomes, enhancing decision-making and increasing confidence in achieving desired business results.
In a bright sunny day, imagine yourself as a COO overseeing your company’s production facility. Suddenly thrust into a high-stakes decision-making scenario demanding extensive research by evening. The time pressure is intense, increasing the risk of errors and uncertainty. Now, envision your organization possessing a Digital Twin of the entire Supply Chain. It autonomously simulates multiple solutions, presenting them on one screen with probability scores based on robust data. All that’s left is for you to select the optimal course of action.
In the business world, certainty is invaluable, and emerging digital twins can provide it. Essentially, a digital twin is a virtual counterpart of a physical entity or process, allowing realistic simulations for a better understanding of real-world behavior. These twins are continuously updated with data from their real counterparts and include behavioral insights and visualizations. When integrated into a single system, digital twins create an Industrial metaverse—an immersive digital environment that replicates and connects all aspects of an organization, optimizing simulations, scenario planning, and decision-making.
These are the four core technologies upon which the foundation of Digital Twin has been built:
