PhD Position in Complex Digital Twins for Infrastructure - Delft, Nederland - Delft University of Technology

Beschrijving

Job description

Digital Twins are proving to be a key innovation, bringing together insights from real-time data, simulation, and predictive analytics to mirror the complexities of physical assets. The relevance of these digital counterparts is in their capacity to provide a detailed, dynamic view of infrastructure systems, enabling proactive decision-making and enhancing operational efficiencies, resilience and sustainability. However, the construction and application of digital twins for infrastructure are inherently complex, necessitating a systematic approach that accounts for the many interactions within these systems and their susceptibility to environmental and operational variances.

Integrating complexity science, network science, and knowledge graphs becomes crucial in addressing these challenges in a complex infrastructure digital twin. Complexity science offers insights into systems' non-linear, emergent behaviours. In contrast, network science provides tools to model and interpret the interdependencies and the flow of information within the infrastructure networks. Knowledge graphs contribute by structuring vast, heterogeneous data into coherent, interconnected models, facilitating a deeper understanding and visualising the relationships and dependencies among various components. Together, these disciplines can create sophisticated, accurate digital twins that reflect the current state of infrastructure assets and predict their future conditions and responses to interventions. Thus, combining complexity science, network science, and knowledge graphs helps create complex digital twins of infrastructure, enabling better understanding, prediction, and management.

This PhD project seeks a candidate to develop an innovative approach for creating an integrated digital twin of infrastructure. This novel method will leverage diverse fields – complexity science, knowledge graphs, network science, game engines, graph neural networks, and multi-simulation integration – to capture the multifaceted nature of infrastructure systems. The research aims to construct a digital twin that incorporates:

• Knowledge graph: Semantic web and ontology engineering principles will be employed to establish a robust knowledge graph, organising and enriching large datasets.
  
• Dynamic behaviours: By utilising frameworks like agent-based modelling, the candidate will capture the intricate interactions within these systems
  
• Multi-simulation integration: The candidate will explore the integration of various simulation tools, enabling the digital twin to incorporate diverse aspects like traffic flow, energy consumption, and structural integrity, fostering a more comprehensive representation of real-world infrastructure behaviour.
  
• Predictive capabilities: Using machine learning methods such as graph neural networks to understand and infer explicit and latent relationships within the infrastructure networks, facilitating the study of emergent properties and future state prediction.
  
  Furthermore, the candidate will utilise game engines to create immersive and interactive simulations, enhancing the digital twin's visualisation and user engagement. This research has the potential to redefine how we understand, manage, and predict the behaviour of complex infrastructure systems.
