Hitachi Review

Highlight

Hitachi has long taken advantage of the benefits and expandability of autonomous decentralization to build control systems for steel industry equipment that is subject to frequent retrofitting and modification. The current practice is to work on advances in control by utilizing ICT to include extensive data collection and analysis functions and provide feedback to control systems. Specific work by Hitachi includes a new thickness control system and an IoT drive system. In the future, Hitachi intends to extend the use of the PDCA cycle by expanding the scope of information use and providing feedback to control systems based on the symbiotic autonomous decentralization concept.
