17Intelligent maintenanceIntelligent maintenance refers to using intelligent algorithms to improve the performance, reliability and availability of engineering assets, making maintenance more cost-effective over the life-cycle of an asset. Bridges are important infrastructure assets, and damage can result in major loss of productivity, or even catastrophic consequences. To ensure bridges are in good condition and prevent serious damage or failure, an intelligent system is needed to process the data collected by sensors, and to analyse the cyclical changes of loads and the responses to changing environmental factors. This enables intelligent algorithms to carry out timely preventive maintenance. Besides transmitting, processing and analysing data, the system is also equipped with decision support tools to calculate the best maintenance strategy, considering downtime, cost and carbon emissions. PolyU%u2019s intelligent health monitoring and maintenance system uses the multi-attribute utility theory, deep reinforcement learning and a decision-making framework to optimise bridge maintenance, extending lifespan and reducing costs.FOREVER YOUNG
