In view of relatively low management efficiency and unbalanced resource allocation in the past port projects constrcution in Yantian Port,we carry out the application research of intelligent management system.We adopt the method of system analysis and design to build a intelligent management system,integrating the latest IT technology,internet of things (IoT),big data and artificial intelligence algorithms technology etc.The system enables to monitor and control the personnel,machinery,materials,methods,and environment in the construction site,and integrate safety,quality,technical,and progress management systems.The results show that construction efficiency is improved by an average of 30%,the rate of safety incidents is decreased by 25%,and construction cost is reduced by 10% after the implementation of the intelligent management system.The system not only successfully resolves the issues of efficiency and resource allocation in traditional port construction,but also provides strong technical backup and serving as management tool for the sustainable development and enhancement for port competitiveness.
