The industrial Internet of Things decentralises the analysis and decision-making and allows for real-time responses. They are basically devices enriched by programming that communicate and interact between themselves and the central controllers. The data generated by these interactions provide opportunity for analysis and decision making in real time to move towards optimising production and energy savings. In recent years the amount of data stored has grown significantly. This trend will increase.
After the mechanization of production by steam power; mass production thanks to electricity; and the digital revolution and electronics enabling an increased automation of production processes, we now have intelligent industry. Industry 4.0 revolves around the concept of the intelligent factory, a factory with all its processes computerized, digitized and connected, and which interact and work more independently thanks to ICT and the Internet of Things.
The global market size of the Internet of Things is forecasted to rise to 14.4 trillion dollars in 2022 (Cisco and Business Insider), with a volume of between 20 to 30 billion connected devices in 2020. This means around four devices for every human being on the planet. In 2003 there were only 500 million worldwide Internet-connected devices.
In the EU, the number of connections will rise from approximately 1.8 million in 2013 to almost 6 billion by 2020. This will bring the market in the EU to over one billion euros in 2020. (Advancing the Internet of Things in Europe. European Commission, 2016). The IoT market revenue will increase from 1,928 billion dollars in 2013 to 7,065 billion dollars by 2020, and aggregate investment in IoT is expected to be 4.8 trillion dollars between 2016 and 2021 (BI Intelligence Estimates).
The Internet of Things opens the door to the 4th industrial revolution
Industry 4.0 transforms design, production systems and products themselves. It creates new business models and has an impact on demand (mass customization, omnichannel access to products and services, predictive knowledge of consumer habits, mass access to information). Manufacturing goes from having individual automated parts to fully integrated automated installations that communicate with each other. Data is gathered and analysed between machines to make processes both faster and more flexible and efficient to produce higher quality goods at lower costs. This increases productivity, promotes industrial growth, modifies the profile of the workforce and redefines the dynamics of global competitiveness in companies and regions. Regarding the IoT’s impact on industry, it is expected that it will grow exponentially over coming years and will lead to a GDP increase in the world's major economies of 10.6 trillion dollars over the next 15 years (Winning with the Industrial Internet of Things. Accenture 2015).
Forecasts suggest that in 2018, 40% of the world’s top 100 manufacturers will rely on connected products to provide their product as a service. The most common applications are:
- In the health field: monitoring and management of diseases, to improve patient welfare.
- Energy management, home savings and security, task automation, design based on the use of domestic appliances
- For retail: automatic payment, store design optimization, smart CRM, personalized in-store promotions, prevention of stock rupture.
- Redesign of office organisation and employee supervision, augmented reality for training, energy monitoring, security of buildings.
- In industrial manufacturing: optimization of operations, predictive maintenance, inventory optimization, health and safety. Also, equipment maintenance, R & D focused on IoT.
- Vehicle upkeep based on predictive prevention.
- In an urban context: public security and health, traffic control, resource management.
- In transport: logistic routing, autonomous cars and trucks and navigation
In a study by ACCIÓ on Industry 4.0 in Catalonia, those companies offering products and services related to IoT in the industrial field have been identified. Due to IoT’s close relationship with other technologies, such as Big Data, Cloud and CyberSecurity, it is difficult to distinguish between companies that work specificallly in each of these technologies, since most work in more than one. All of these companies form the "data and connectivity" segment, which encompasses 150 consolidated companies, with a collective turnover of 1,421 million euros and 7,437 employees.
