Definition

A digtial twin uses data and information from sensors and other sources to simulate the behavior and performance of its physical counterpart in real time. Digital twins can be used for various purposes, including monitoring, optimization, prediction, and control.

In order to create a digital twin, several steps are required:

  1. Collect data about the physical object or system. This could include sensor data, operational data, and historical data. The more comprehensive and accurate the data, the better the digital twin will be able to represent the physical counterpart.
  2. Create the digital twin using modeling and simulation software. This involves constructing a mathematical model of the physical object or system based on the collected data.
  3. Validate the digital twin by comparing its behavior to that of the physical counterpart. This step is important for ensuring that the digital twin accurately represents the physical object or system.
  4. Use the digital twin to perform experiments and simulations. These can be used to optimize the performance of the physical object or system, predict future events, or identify potential problems.

Example

One common example of a digital twin is a virtual replica of a piece of industrial machinery, such as a wind turbine or a pump. The digital twin is created using data from sensors installed on the physical machine, which monitor factors such as temperature, pressure, and vibration. This data is used to create a mathematical model of the machine, which is then implemented in a software platform to create the digital twin.

Digital twins are not limited to individual machines – they can also be used to model entire systems, such as a fleet of vehicles or a network of factories. In these cases, the digital twin provides a holistic view of the entire system, enabling operators to manage and optimize it as a whole.
