Standards Development
This document provides a collection of representative use cases of Digital Twin applications in a variety of domains, e.g., smart manufacturing, smart cities, etc.
This document can be used in the development of other standards and in support of communications among diverse, interested parties/stakeholders.
This document is applicable to all types of organizations (e.g., commercial enterprises, government agencies, not-for-profit organizations).
A Digital Twin is a digital representation of a particular physical entity or a process with data connections that enable convergence between the physical and digital states at an appropriate rate of synchronization, and provides an integrated view throughout the lifecycle of the physical entity or the process.
The concept of the Digital Twin dates back to a University of Michigan presentation to industry 2002 for the formation of a Product Lifecycle Management (PLM) center,and was initially used in the military and aerospace fields. Similar to the U.S. Air Force Research Laboratory and NASA based on digital twin aircraft health control applications, Lockheed Martin introduced digital twin into the F-35 fighter production process, to improve the process, productivity and quality. Digital twin has been applied to all stages of the product lifecycle, including product design, manufacturing, service and operations, due to the characteristics of virtual fusion and real-time interaction, iterative operation and optimization, and full-element/full-process/full-business data driver. In the face of the wide application of digital twin in various scenarios, it is particularly important to carry out the standardization of digital twin. The first needs to be done is to collect use cases to provide fundamental basis for standardization.
The purpose of the Digital Twin Use Case is twofold:1) helped to group and categorize the use cases according to the identified application domains; and 2) to find the new technical requirements (standardized demand) from the market, accelerating the transformation of science and technology achievements.
