Special Issue Information

Dear Colleagues,

In recent years, the "digital twin" technology has received rapid development, aided by advances in smart sensors, Internet of Things, cloud computing and artificial intelligence, and has captured major interest from the manufacturing industry. Digital twin technologies are a key component in the implementation of intelligent manufacturing, Industry 4.0 and cyber-phyiscal systems.

A digital twin, in the context of manufacturing, is a virtual and digitalized representation of a manufacturing system, a manufacturing process or a manufactured product. Through physical modelling/simulation, identification testing and increasing available big data, the digital twin can accurately predict the response of the physical object/process, enabling production visualization, process optimization, real-time monitoring and predictive maintanence of the manufacturing system and processes, etc, which leads to better product quality, improved systems design and holistic production line management. With increasing demand of digital twin technologies in manufacturing, issues such as improving the model accuracy, effective digital twin deployment to improve the physical system and full life-cycle monitoring and predictive maintenance remain challenging.

This Special Issue aims to provide a forum to present the state of the art in the development and application of digital twin technologies in manufacturing, and to introduce innovative approaches to address issues that are currently limiting the application potentials of digital twin technologies. 

 Researchers are invited to submit their work related to, but not limited to, the following topics:

  • Development of digital twins of manufacturing (and metrology) process/systems/products;
  • Novel technologies underpinning the digital twin technology;
  • Innovative approaches to improve accuracy of the digital twin;
  • Application of digital twins to improve the physical systems;
  • Monitoring and predictive correction/control/maintanence;
  • Digital twin-enabled production visualization and management.

Recovering old machinery, once it reaches its end of life, allows companies to be sustainable. Several strategies are available for this purpose, both from the point of view of hardware and software modifications. Especially in the industrial sector, these strategies are classified as revamping, remanufacturing and retrofitting. Machinery revamping, retrofitting and remanufacturing are all used to improve industrial equipment performance, efficiency and sustainability. Each approach has unique benefits and trade-offs, depending on the specific needs and requirements of the equipment and business. Moreover, according to Industry 4.0 principles, it is also possible to talk about smart retrofitting, involving the integration of various technologies such as sensors, automation systems, Digital Twins, artificial intelligence and data analytics software to control and optimise the operation of the machinery. Digital Twins, in particular, have been widely used among smart retrofit solutions and can integrate several innovative aspects of dated systems. However, a literature review needs to clarify their meaning and specific characteristics. For this reason, this paper aims to distinguish different strategies and find a correct definition of smart retrofitting, highlighting its relevance, benefits and sustainability in the industrial sector, focusing more on Digital Twin solutions for smart retrofitting.
