The Evolution of Industry 4.0
To understand the impact of Industry 4.0, it’s important to understand the evolution of industry from 1.0 to 4.0:
Industry 1.0
Mechanical production facilities were introduced to the world in the late 18th century, paving the way for steam-powered machines to help workers in manufacturing. The increased production efficiency that these machines provided helped small businesses grow into large organizations with owners, managers, and employees. Industry 1.0 is also deemed as the beginning of industry culture.
Industry 2.0
Industry 2.0 began at the start of the 20th century with the development of machines running on electrical energy. Electrical machines were more efficient to operate and maintain than their steam-powered counterparts, paving the way for a more cost-effective, productive factory floor. The first assembly line was built during this era, further streamlining the process of mass production.
Industry 3.0
Industry 3.0 was centralized around the advances in the electronics industry in the last few decades of the 20th century. The invention of technologies including transistors and integrated circuits revolutionized manufacturing, as they automated machines on the factory floor that resulted in reduced effort, increased speed, greater accuracy, and freed up the human workforce for more advanced tasks.
The integration of electronic devices and machine automation created a requirement of software systems, fueling the software development market. The software systems paved the way for management processes such as enterprise resource planning, inventory management, shipping logistics, product flow scheduling, and tracking throughout the factory.
As expected, the automation of machines and introduction of advanced software systems have evolved over the years as advancements are made in the electronics and IT industries. This is driven by the pressure to reduce costs and speed up production and has led to many companies moving their manufacturing to low-cost countries. This dispersion led to the formation of the concept of Supply Chain Management.
Industry 4.0
Industry 4.0 was introduced in the 1990s as the internet and telecommunications transformed the way we connected and exchanged information. This technology merged the boundaries of the physical and virtual world, and cyber-physical systems (CPS) further blurred this boundary in manufacturing, introducing an influx of new technologies into the industry. CPS allows machines on factory floors to communicate more intelligently with each other, minimizing physical and geographical barriers.
Industry 4.0 technology uses CPS to share, analyze, and guide intelligent actions for different processes involved in manufacturing. Having all the different machines on a factory floor connected and sending real-time data to the cloud creates the concept of a 'Smart Factory'. These smart machines monitor, detect and predict faults, suggesting preventive measures and remedial action before downtime occurs.
CPS also allows manufacturing processes to be virtually visualized, monitored, and managed from remote locations. Industry 4.0 puts machines, people, processes, and infrastructure into a single, connected manufacturing process, which provides businesses with full disclosure over the entire workings of their manufacturing and production. Using this information makes overall management highly efficient.
How Does Industry 4.0 Work?
One of the best ways to understand Industry 4.0 is to think about how it is applied in manufacturing. Here are three use cases that will help you recognize the value Industry 4.0 can add to a manufacturing operation:
Supply Chain Management
Industry 4.0 technologies allow businesses to have greater insight, control, and data visibility over their supply chain. Smart manufacturing means that companies can deliver products and services faster, cheaper, and with better quality. As more and more businesses use Industry 4.0 solutions for supply chain management, the market becomes more competitive, forcing companies to adopt a similar strategy or risk falling behind.
Predictive Maintenance
Industry 4.0 solutions and a connected factory floor can be used to predict potential downtime in machinery before it occurs. Without IoT systems, preventive maintenance must be done manually and happens based on routine or time. Industry 4.0 systems sense problems before they arise and can even provide insight on how to solve issues before they become a problem.
Asset Tracking and Optimization
Industry 4.0 makes it easier for businesses to track inventory, quality, and optimization opportunities related to logistics. Connected manufacturing and the IoT provide employees with visibility over company assets worldwide. Standard asset management tasks such as asset transfers, disposals, reclassifications, and adjustments can be streamlined and managed centrally and in real-time.
