4.0 to 5.0: Ten years of Digitization to Sustainable Human Centric Industry

Diego Galar

Luleå University of Technology, Sweden


The digital transformation of industry has been rapidly accelerating thanks to one decade of Industry 4.0 enabling technologies transforming how we produce and consume goods and services. This revolution is characterized by the integration of advanced technologies into the manufacturing process, including cyber-physical systems, the Internet of Things (IoT), and cloud computing. These technologies have paved the way for the creation of digital twins, virtual representations of physical objects or systems, which can be used to optimize and improve products and services.

As we look ahead to Industry 5.0, we must consider the potential of emerging technologies such as the metaverse and industrial AI. The metaverse refers to a virtual world, a fully immersive and interconnected virtual space, where individuals can interact with each other and with digital objects. In Industry 5.0, the metaverse can be leveraged to enhance collaboration between human-machine and machine-machine, bringing together individuals from different locations and backgrounds to solve complex problems and create innovative solutions. Industrial AI, on the other hand, refers to the integration of artificial intelligence (AI) into industrial processes becoming the AI engine of such metaverse facilitating a new playground for industry where processes are more efficient and sustainable. This virtual space powered by AI can also be used to predict and prevent equipment failures, reducing downtime and maintenance costs, evolving the Maintenance 4.0 concept to Maintenance 5.0.

In this speech, we will explore the journey from Industry 4.0 to Industry 5.0 and discuss the role of digital twins, the metaverse, and industrial AI in achieving a sustainable, human-centric industry. We will examine the challenges and opportunities presented by these emerging technologies and their potential to transform industry. We will also look at the role of businesses, policymakers, and society in shaping the adoption of these technologies and highlight the importance of collaboration and innovation in achieving this goal.

Ultimately, this speech aims to inspire and inform individuals and organizations to embrace the possibilities of a digital future that puts people and the planet at the center of industry. By harnessing the power of emerging technologies to enhance collaboration, creativity, and sustainability, we can create a better future for all.
