The Busan Waterworks Authority has independently developed a digital twin-based next-generation public administration platform. The system goes beyond simple document automation by integrating facilities, spaces, data, and AI into a single three-dimensional (3D) environment, building what is evaluated as the first public AI model of its kind among local governments nationwide.
Busan City announced Wednesday that it will hold a presentation on the development of the digital twin-based "Integrated Public Affairs Platform" at the Waterworks Authority on the afternoon of the 28th. The platform fundamentally transforms the public affairs execution system based on digital twin technology, which builds a digital environment identical to physical space.
The newly unveiled "Sangsu iN2.5" represents an evolution from the previous single-AI-agent-centered system. It adopts a "Multi-Agent Orchestration" approach in which AI agents specialized in different roles—audit, legal analysis, facility operation, and situational response—organically collaborate.
The city previously unveiled "Sangsu iN," its first independently developed AI agent, in February—a national first. In just three months, the city has independently implemented a multi-AI collaboration system, advancing public AI administrative innovation.
The platform goes beyond document search based on simple Retrieval-Augmented Generation (RAG), integrating facility, spatial, and operational data into a 3D environment. It visualizes the operational status and data of public facilities in real time, with AI analyzing the information to support decision-making and situational response.
The city expects benefits including improved facility operation efficiency, reduced decision-making time, and lower maintenance costs by leveraging operational experience and real-time data accumulated in the waterworks sector. The plan is to develop the system into a general-purpose platform model that can be expanded beyond waterworks to other public administration fields.
"Following the nation's first unveiling of an independently developed AI agent, we have now implemented a Multi-Agent Orchestration structure, advancing public AI innovation to the next level," said Acting Mayor Kim Kyung-deok. "Through advanced AI technology, we will make Busan a leading city in administrative innovation."
