Nezha-ITOS, the intelligent terminal optimizer solution reconstructed traditional terminal process by connecting IT, port-handling equipment, and electric-control system seamlessly. It has put into application of latest algorithm, modelling, big-data and AI to create an integrated solution which ensures an energy-saving, carbon-neutral and highly efficient operation for ports. Shanghai-Yangshan-IV, the largest automated container terminal worldwide, equipped with Nezha-ITOS, is to hit five-million-TEU-throughput 2021. 21 QCs can work round the clock, automatically and concurrently, while maintaining a high & stable level of 1000-TEU-throughput per crane per day. Nezha-ITOS has exceeded other system standards currently used by existing automated and traditional terminals globally.
