PhD defence by Lijia Long
Lijia will defend her PhD thesis "Quantification of the Value of Monitoring Information for Deteriorated Structures". All are welcome.
29.06.2021 kl. 15.00 - 19.00
You are the infrastructure owner, you are responsible to ensure the safety of the infrastructures. You are facing the challenges to make decisions every day. But you are not sure, when to do the maintenance? Is it worthy to do monitoring? Which SHM techniques to choose? Where to install the sensors? What actions to take?
This thesis has developed a new framework to let your investment be worthy, through quantification of the value of monitoring information for deteriorated structures to find the optimal strategies with the highest value. The framework is based on the Bayesian decision theory utilizing the decision tree tools, structural and monitoring system reliability analysis with probabilistic modelling, cost and benefit analysis considering the consequences modelling.
In the end, a value of information-based decision guideline will be provided and you will get to know whether to do the monitoring, when to do the monitoring, and when to do the maintenance. So that you will be able to reduce risk, reduce cost, increase the service life benefits for the value of industry and society, and achieve the sustainability of the world.
