Historical Background
The concept of the intelligent factory has evolved significantly over the past few decades, rooted in the early stages of the Industrial Revolution. The First Industrial Revolution in the late 18th century introduced mechanization and steam power, revolutionizing production processes. This period marked the beginning of large-scale manufacturing, shifting from manual labor to machine-based production.
The Second Industrial Revolution in the late 19th and early 20th centuries brought electricity and assembly lines, further enhancing manufacturing efficiency. Factories became more complex, incorporating electrical machinery and mass production techniques. This era laid the foundation for modern manufacturing, emphasizing efficiency and scalability.
The Third Industrial Revolution, beginning in the mid-20th century, introduced digital technology and automation. Computers and programmable logic controllers (PLCs) started to be integrated into manufacturing processes, enabling more precise control and automation. This period marked the beginning of the transition towards smarter, more automated factories.
