Special Issue on Digital Twin and AIoT

Computational systems that interact with the real world may need to assess, simulate, and monitor the effects of its actions; they may need to watch out for and respond to environmental changes in a timely manner. In order to achieve these purposes, it is often beneficial to build a faithful digital model of the real world, known as a Digital Twin. Such models have proven indispensable for smart manufacturing, precision agriculture, and many other application areas.

The technology of Digital Twins and Artificial Intelligence of Things (AIoT) achieves the above goals by the combined use of ubiquitous sensors, Internet of Things, data analytics and artificial intelligence. Building a Digital Twin is no small undertaking, requiring interdisciplinary collaboration, systematic thinking, and thorough understanding of the application domain.

This special issue contains four articles on the topic of Digital Twins and AIoT with insights from both the academia and the industry, covering applications in manufacturing, e-commerce, and agriculture, as well as the relationship between knowledge graphs and Digital Twins. On behalf of the IJIT Editorial Board, I hope that this special issue can provide our readers with examples and insight of how Digital Twin and AIoT systems are conceived, designed, and/or implemented and can facilitate the realization of the Smart Nation that is Singapore.

Yours Sincerely

Chunyan Miao, Chief Editor
