Review on Digital Twin Modelling Applications To Support Human-Centricity in Manufacturing

In today's manufacturing environment the Industry 5.0 (I5.0) paradigm has emerged and the concept of human-centricity started to be integrated enhancing workers roles, prioritizing their physical health, mental health and well-being. In particular, to support humans in their workplace, the Digital Twin (DT) paradigm can serve for designing and/or analyzing manufacturing environments that improve workers' well-being. Recently, this approach has evolved into the concept of Human Digital Twin (HDT) which aims at presenting a comprehensive representation of the human entity analyzing their behavior and understanding possible improvement approaches for workers status. The aim of this paper is to analyze, through a systematic literature review, DT solutions that support human-centric manufacturing systems, focusing also on the roles played by technological tools in assisting operators in their work environment. In this sense, attention will be devoted to improving human factors through modelling approaches and technological tools.
