Industry 4.0 The Industrial Revolution 4.0 Principles

What is Industry 4.0?

→ Industry 4.0 or the Fourth Industrial Revolution is based on the cyber-physical transformation of machining and manufacturing.
→ The current trend of automation and data exchange in manufacturing technologies is known as Industry 4.0.
→ Sometimes it is also known as "I4.0" or "I4"
→ This name has arrived from the German government's initiative to promote manufacturing and a digital convergence between industries and the computerization of manufacturing.
→ The basic principle is that connecting machines, workpieces, processes, businesses, and many other things are creating intelligent networks along the entire value chain.
→ All these things control each other autonomously.
→ An example of the Smart Factory concept is a machine that can predict the probability of failure and start maintenance processes autonomously before the failure happens.
→ In a smart factory, millions of machines, managed by the machines themselves, fortunately using Artificial intelligence developed by humans.

What is the Industrial Revolution?

→ The changes in manufacturing and transportation with the help of new technologies are called the Industrial Revolution.
→ Example: Initially a product was made by hand then it was made by machine then it was manufactured on a larger scale by mass production.

Types of Industrial Revolution:

→ The four types of industrial revolutions are explained below.

Milestone of the Industrial Revolution

What is the First Industrial Revolution?

→ It has happened in the 18th to 19th centuries in Europe and North America.
→ In that period many agrarian and rural societies became industrial and urban.
→ In this duration, the iron ore and textile industries were developed.
→ And mechanization made possible by steam power and water power.

What is the Second Industrial Revolution?

→ The Second Revolution - 1870 and 1914, just before World War I.
→ In this period pre-existing industries were developed rapidly.
→ New businesses, such as steel, oil, and electricity, and used electric power to create mass production were also developed very speedily.
→ Many technical things also developed during this period such as the telephone, light bulb, phonograph, and the internal combustion engine.

What is the Third Industrial Revolution?

→ It is also called Digital Revolution and it was started in the 1980s and still is continuing.
→ This revolution refers to the technology from analog electronic devices and mechanical devices to digital technology.
→ This includes the personal computer, the internet, information, and communications technology, and automated machines and production processes.
➨ It has the potential to grow in the field of,

     ⇢ 5G networks and the internet of things and
     ⇢ Renewable energy.

What is the fourth industrial revolution?

→ The biggest impact of the Fourth Revolution is to improve the quality of life.
→ This is fundamentally different from the previous three
➨ Breakthroughs by this revolution (4IR) in below fields,
     ⇢ Robotics,
     ⇢ Artificial intelligence,
     ⇢ Nanotechnology,
     ⇢ Quantum computing,
     ⇢ Biotechnology,
     ⇢ The Internet of Things (IoT),
     ⇢ The Industrial Internet of Things (IIoT),
     ⇢ Decentralized consensus,
     ⇢ Fifth-generation wireless technologies (5G),
     ⇢ Additive manufacturing/3D printing and
     ⇢ Fully autonomous vehicles.
→ These technologies will connect billions of more people.
→ It will improve the efficiency of businesses and organizations.
→ This revolution will help to regenerate the natural environment through better asset management.

Design Principles of Industry 4.0

  1. Interconnection
  2. Information Transparency
  3. Technical Assistance
  4. Decentralized decisions

[1] Interconnection

→ Interconnection is the ability of machines, devices, sensors, and people to connect and with the help of the Internet of Things, they communicate with each other.
→ It allows us to monitor the effectiveness and efficiency of our process with the help of wireless communication technology and capabilities of the Internet of things (IoT)

[2] Information transparency

→ Information transparency provides large amounts of useful information to make appropriate decisions from all points in the operation process.
→ Inter-connectivity allows operators to collect large amounts of data and information from the operation process.
→ This large amount of information will be used for analysis, innovation, and improvement.

[3] Technical assistance

→ Technical assistance is the key principle for this revolution.
→ In technical assistance, the role of humans as an operator of machines is shited to a problem solver and decision-maker in this concept.
→ Technical assistance helps to solve urgent problems on short notice.
→ It supports to conduct tasks that are unpleasant and unsafe for the human worker.

[4] Decentralized decisions

→ The decentralized decision allows an operator to make a decision from inside the production plant facilities as well outside of the factory.
→ It is possible due to Interconnection and information transparency provided by decentralized decision.
→ Decentralized decisions combine local and global information at the same time.
→ It supports better decision-making and increases overall productivity.

Technologies in Industry 4.0

➨ There are various different technologies are used is such as, Autonomous Robots, Simulation, Horizontal and Vertical System Integration, The Industrial Internet of Things, Cyber Security, Cloud Data Computing and Storage, Additive Manufacturing, Augmented Reality, Big Data Analytics.

The Nine Pillars of Industry 4.0

  1. Autonomous Robots
  2. Simulation
  3. Horizontal and Vertical System Integration
  4. The Industrial Internet of Things
  5. Cyber Security
  6. The Cloud Data Computing and Storage
  7. Additive Manufacturing

Technologies in Industry 40

Autonomous Robots

→ Many industries have robots to complete complex assignments.
→ They are becoming more autonomous, cooperative, and flexible.
→ Robots work safely in a hazardous condition also.
→ The robots will have great capabilities.
→ Very interactive collaboration with a human is possible by high-end sensors and control units.
→ Nowadays robots can automatically adjust their actions.


→ Nowadays 3-D simulations of production processes, products, and materials in production processes are already used.
→ But in the future, simulations will be used on a large scale in manufacturing.
→ These simulations will allow operators to test and optimize the machine settings for the next product in the virtual world before the physical changeover.
→ Therefore, machine setup time will be reduced by 80 percent and increases Product Quality.

Horizontal and Vertical System Integration

→ Companies, suppliers, and customers are rarely closely linked.
→ Any departments such as engineering, production, and service are not integrated.
→ Top management and bottom management are not fully integrated.
→ In this technology, companies, departments, functions, and capabilities will become universal data-integration networks and enable truly automated value chains.

The Industrial Internet of Things [IIoT]

Big Data Analytics

→ By data analytics, we can optimize production quality, saves energy, and improves equipment service.
→ In an Industry 4.0, the collection and comprehensive evaluation of data from many different sources will become standard to support real-time decision making.
➨ The 6C system in Big Data Analytics:
     ⇢ Connection (sensor and networks)
     ⇢ Cloud (computing and data on demand)
     ⇢ Cyber (model & memory)
     ⇢ Content/context (meaning and correlation)
     ⇢ Community (sharing & collaboration)
     ⇢ Customization (personalization and value)

➨ There are two types of issues are available in the factory, visible issues, and invisible issues.
→ Industry 4.0 is capable to handle these issues with the help of an algorithm.
