High Speed Railway Degradation Modelling

高速铁路基础设施是一个复杂的系统和结构安排，包括：轨道，开关，排水，信号，供电和通信，除了土方工程，隧道，桥梁和车站的土建结构。随着新的高速铁路的建设，重要的是要制定计划，以确保它们是可持续的和负担得起的，以便在它们磨损或因新技术而过时时可以更新。为了能够计划更新，有必要了解所有基础设施元素是如何由于时间的流逝或使用而退化的。这可以估计何时需要更换，并且可以使用包括人工智能（AI）在内的建模方法来实现。这个项目是开发和应用的方法，通过数据，表明时间和使用情况对铁路状况的影响，可以预测更新的预期时间是必要的。

High-speed railway infrastructure is a complex arrangement of systems and structures, which includes: track, switches, drainage, signalling, power supply and communications, in addition to the civil structures comprising earthworks, tunnels, bridges and stations. As new high speed railways are built, it is important that plans are in place to ensure that they are sustainable and affordable so that elements can be renewed as they wear out or become obsolete due to new technologies. To be able to plan for renewals it is necessary to understand how all the infrastructure elements degrade due to either the passage of time or use. This enables the estimation of when replacement is necessary, and can be achieved using modelling methods which include artificial intelligence (AI). This project is to develop and apply methods by which data, indicating the effects that time and usage have on the railway condition, can be used to predict the expected time that renewal will be necessary.
