The 3D Geoinformation Group and AiDAPT Lab invite applications for a funded PhD position in the area of Data-/AI-driven infrastructure inspection and maintenance planning. We are looking for candidates highly motivated to work at the confluence of AI, geoinformation, infrastructure safety & sustainability, and algorithmic decision-making, in order to address the life-cycle extension needs of our aging and growing transportation systems.

A significant part of our transportation infrastructure, including roads and bridges, has reached or exceeded its design life. To extend the life of infrastructure in the future and at the same time meet sustainability goals, it is necessary to optimize interventions by predicting the most effective inspection and maintenance strategies, while reducing emissions, and network disruptions due to construction works or poor asset structural conditions, among others.

This PhD research will investigate how optimal inspection and maintenance strategies can be devised using geo-data, engineering models, and AI. The case study will be the city of Amsterdam, however, the methods to be developed will be generic. The PhD research will commence with an inventory of the already existing inspection and maintenance data and will first develop a method to get structured insight into degradation over time based on these historical geo-based data. In a second step, the method will be further developed to propose optimal inspection and maintenance strategies by incorporaing the various factors affecting the condition of infrastructure and its stochastic degradation over time. The method will be validated using historical evolution of road and bridge asset conditions. It will result in a probabilistic digital twin based on which we can simulate intervention actions as the third step, such as repairs, upgrades, inspections, and monitoring system installations. The effects of such interventions will be modeled as an advancement of the digital twin in a fourth step, including improvements to asset condition, delays in deterioration processes, and uncertainty in damage detection. The direction that we intend to explore is developing a novel AI pipeline for this purpose to model the effects as key performance indicators. AI models will interact with the digital twin to generate and optimize policies on when and where to inspect and perform maintenance, based on expected degradation and meeting multiple sustainability goals. For the AI pipeline, the potential for obtaining training data to establish key performance indicators from simulations will be explored, such as traffic changes, carbon emissions, and climate change risks.

The candidate's background can further motivate directions of this PhD project in coordination with supervisors and stakeholders.

The PhD candidate will combine expertise on geo-data, digital twins, and algorithmic decision-making. She/he/they will be supervised by Prof. dr. Jantien Stoter (3D Geoinformation Group) and Dr. Charalampos Andriotis (AiDAPT Lab). The candidate will work as part of a team within the groups, closely collaborating with researchers, engineers, and stakeholders associated with the City of Amsterdam and the Amsterdam Institute of Advanced Metropolitan Solutions. The research will be carried out in the context of the National Growth Fund project “Future proof living environment”. The position is funded for a duration of 4 years, during which the candidate will undertake research on their PhD topic and contribute to the research agenda of the research groups, also dependent on the interest of the candidate.
