It might sound futuristic, but the Fourth Industrial Revolution - also known as Industry 4.0 - has already begun.
Following the Industrial Revolution’s steam power, electrification in the 1800s, and the Digital Revolution of the late 20th century, Visual Capitalist's Omri Wallach details below how Industry 4.0’s innovative smart technology is unlocking the next steps in automation.
So what does the next major evolution of manufacturing look like? This graphic from ASE Global breaks down the rollout of Industry 4.0, from increased robotization to lights-out manufacturing.
The Basics of Industry 4.0
Each industrial revolution has built on what came before, incorporating new technologies and knowledge of manufacturing. Industry 4.0 has four core principles paving the way:
Interconnection: Machines, devices, sensors, and people in the manufacturing process all connecting and communicating with each other.
Information transparency: Comprehensive data and information being collected from all points in the manufacturing process, allowing for more informed decisions.
Technical assistance: Improved technological facility of systems assisting humans in decision-making, problem-solving, and difficult or unsafe tasks.
Decentralized decisions: Cyber physical systems that are able to make decisions on their own and perform tasks autonomously.
Combining these principles is what makes the ongoing Fourth Industrial Revolution unique. Much of the underlying technology has been available for decades, including robotics and networks, but properly using them together unlocks a massive stride in manufacturing capabilities.
Already, the market size for Industry 4.0 specific technology was estimated to be $116.1 billion in 2021. By 2028, it’s projected to grow almost three times to $337.1 billion, with core components leading the way.
These technologies are already being rolled out in smart factories around the globe, and the most robust and up-to-date versions are being used to unlock the next evolution: lights-out manufacturing.
What is Lights-Out Manufacturing?
Where traditional factories and even smart factories require some direct human interaction, true lights-out factories operate completely autonomously.
Though it might sound like a dream, lights-out factories are fully automated, 24/7 factories with no on-floor human presence. And they already exist in the modern world.
Japanese robotics designer FANUC has been using robots to build themselves in a lights-out factory for 20 years, and even electronics company Philips uses 128 robots in a lights-out manufacturing line to produce electric razors.
One industry that uses lights-out manufacturing extensively is semiconductor manufacturing. ASE Global, the world’s leading provider of semiconductor manufacturing services in assembly and test, used 18 completely automated factories in 2020 alone.
Unlocking Lights-Out Factories
Different businesses and industries will be able to utilize Industry 4.0 technologies in different capacities, and lights-out manufacturing is no different.
Though incorporating fully autonomous factories can unlock huge potential, there are also significant challenges to first overcome.
Which industries will implement lights-out manufacturing? New robot installations in 2019 show that the automotive, electronics, and metal and machinery sectors are unsurprisingly leading the way in Industry 4.0 implementation.
The Industry 4.0 Snowball Rollout
As 4.0 technology improves and costs decrease, the implementation of lights-out capabilities is expected to surge.
A global survey of businesses for their 2025 production plans show that 17% are anticipating having completely lights-out manufacturing, while 79% of manufacturing will be human-driven but digitally-augmented to some degree.
And like other industrial revolutions before, the technological rollout quickly creates a snowball effect that speeds its growth:
Demand increases for cyber physical systems and smart machines.
The supply of smart-capable machines with semiconductors increases.
Bigger and more robust networks of machines are assembled.
Improved capabilities further increase demand.
Many industries are capable of benefiting from 5G, IoT, and more robust usage of data and machines in some way. The question of when your sector will see Industry 4.0 is either sooner than you think, or it has already begun.
