Industry 4.0 signifies the promise of a new Industrial Revolution. Concept of Industry 4.0 is not simple. It covers many technologies and is used in different contexts. There are many technologies that define industry 4.0, and some of them are: IoT, Big data, 3D Printers, Smart Factory, cloud computing, Cyber-Physical Systems. IoT allows to embed the information of physical objects into virtual world, and in the end brings with the merging between real and virtual systems. Therefore, IoT is to somehow foundation for the construction of Cyber-Physical Systems. Big Data is actually a mass of diverse data that arrives at a high speed and frequency and is therefore constantly increasing their volume (3V - volume, velocity, variety). A smart factory is a step forward from traditional automation to a fully-fledged and flexible system - one that can use a steady stream of data from related operations and production systems to learn and adapt to new requirements. Cloud computing is an information technology (IT) paradigm, a model for enabling ubiquitous access to shared pools of configurable resources such as computer networks, servers, storage, applications and services. Cyber-physical systems are the basis of industry 4.0. They connect physical objects, enviroments and machines through digital devices such as sensors, which collect and analyse data and make decisions based on it. Recent years have seen the rise of connected technologies throughout the manufacturing and distribution value chain. This combination of digital and physical systems, known as Industry 4.0 has paved the way for increasingly connected experiences that impact everything from product design and planning to supply chain and production. Beyond the processes of designing and producing goods, however, the technologies inherent in Industry 4.0 can also impact the manner in which finished goods are moved, warehoused, and distributed.
