The Kedi Intelligent Water Industry Smart Operation Decision System (KDAIde®) is a next-generation comprehensive management system specifically tailored for intelligent production and operation in water enterprises. The system strictly follows national and industry guidelines and relevant standards. Based on a dual-core architecture of “Data Center + Knowledge Center,” it integrates artificial intelligence knowledge graphs and large model technologies to enable users to analyze production data in real time, efficiently construct knowledge graphs, and accurately address multi-scenario decision-making challenges in complex production tasks. The system achieves intelligent control across production operations, maintenance, and asset management. By applying this system, operational managers can intuitively monitor, predict, and optimize production processes, proactively respond to shock loads and hydrological anomalies, significantly improve water management efficiency and accuracy, and promote the industry’s transformation toward intelligence and sustainability.
