Abstract: With the deep integration of next-generation information technology and high-end equipment manufacturing, traditional maintenance models face a series of severe challenges in terms of real-time performance, intelligence, and full lifecycle management. This study takes a digital intelligence transformation perspective to systematically explore the digital intelligence maintenance management model driven by next-generation information technology, aiming to construct a new maintenance paradigm that integrates technology, functionality, and organizational collaboration to promote high-quality development in the industry. The study reveals the core characteristics of digital and intelligent operations and maintenance: data-driven decision-making, intelligent technology penetration, full lifecycle management, cross-domain collaboration, and diversified value creation. Based on this, the study proposes a three-tier operations and maintenance management model of “technology-function-organization” and combines the technological foundation, functional closed loop, and industrial ecosystem to achieve a paradigm shift in operations and maintenance management from passive response to proactive prevention and value co-creation. Case studies demonstrate that Goldwind Technology has validated the significant effectiveness of the digital-intelligence operations and maintenance model in enhancing efficiency, optimizing resources, and promoting collaboration by integrating technologies to build a closed-loop system. The study further proposes a path for constructing an operations and maintenance service ecosystem, providing theoretical support and practical guidance for the digital transformation of the high-end equipment manufacturing industry.
