Factory of the future, Industry 4.0, cyber-factory or connected factory: Regardless of what it is called, this transformation of industry represents a revolution in manufacturing processes based on new technologies and innovative concepts. Why is it called Industry 4.0?\
Because before getting at this point, three successive industrial revolutions had already taken place:
- The first, in the 18th century, was characterized by mechanized production using coal and the development of the steam engine….
- The second, at the end of the 18th century, allowed for mass production after the arrival of electric power.
- The third, in the middle of the 20th century, allowed for automated production, using machine control and robots.
With Industry 4.0, the sector is entering its fourth revolution, characterized by a merging of the Internet and factories. At each link in the production and supply chains, tools and workstations communicate constantly via the Internet and virtual networks. Machines, systems, and products exchange information both among themselves and with the outside. By optimizing production tools, manufacturers hope to speed up production at a lower cost, and in a more environmentally sound way.
In some countries, Industry 4.0 is already a reality. In Brazil, some industries already incorporate the new technologies into a strategy for development and competitiveness. Accenture estimates that the implementation of Internet technologies in various sectors of the economy should impact the Brazilian GDP by approximately US $ 39 billion by 2030.
(2) McKinsey estimates that, by 2025, industry-related processes 4.0 can reduce equipment maintenance costs by 10% to 40%, reduce energy consumption by 10% to 20%, and increase work efficiency by 10% to 25%.
A transformation of industry more than a revolution
The main tools needed to implement Industry 4.0 already exist: sensors, controllers, big data (lien vers lexique), the Internet of Things (lien vers lexique), cloud computing (lien vers article cloud computing)… More to a technological revolution, Industry 4.0 is rather than a complete reorganization of the mode of production using existing tools and placing greater reliance on networks. This new generation of factories aims to revive the dynamism of European industry in several ways: by modernizing production, increasing competitiveness, and positioning manufacturers to face the challenges of globalization etc
What Industry 4.0 means?
Behind this initiative waits a real revolution: by being interconnected, machines are capable of manufacturing products intelligently. In fact, this is reflected in many ways, for example:
- More flexible production which allows for real-time adaptation to demand;
- Advanced tracking to inform us not only where and when a product was manufactured but also by what method. In addition, security checks throughout the manufacturing process allow for rapid and precisely targeted recalls in case of failure;
- Machines capable of contacting a specialist to troubleshoot them at distance, and which can update themselves and improve their performance through the Internet;
- A scripted manufacturing cycle in which production is directed according to the customer’s requirements and which is capable of customize the product (size, color, packaging…);
- Optimization of consumption based on energy efficiency: Production is optimized according to the cost of energy and its availability throughout the day, while it is less expensive or while alternative energies can be used. Machines are also powered down if they do not need to be running. Information feedback can also help to optimize consumption and thus participate in the energy efficiency of the factory;
- In addition to improving the security and safety of personnel at work, these factories allow greater value to be placed on people by assigning them tasks that add value;
Industry 4.0 from VINCI Energies
Actemium, the VINCI Energies brand dedicated to industrial processes, is active in optimizing the production, maintenance, and energy efficiency of factories. For example, it has implemented a computerized industrial system for real-time production to be able to ship car seats on demand. The manufacturing of a seat is thus initiated at the same time as the production of the vehicle in which it will be installed, so is “just in time”. Actemium has also designed a software application that permits 3D virtualization of a manufacturing plant. Assembly lines are displayed using the latest networked modelling technologies. The plant takes form before our eyes. Every significant change (addition of an assembly line, an element in the production chain…) is modelled to verify its integration with the current process.
Connections among machines engender many challenges for manufacturers: how to get them to communicate with each other, as well as how to collect, store, and manage the vast amount of information derived from their sensors. Axians, the VINCI Energies brand dedicated to information and communications technology (ICT), is involved and implements efficient telecommunications infrastructures along with cloud computing. The same brand also creates, manages, and ensures the maintenance of the IP network necessary for inter-machine communication.
