About the position

We have a vacancy for a PhD Candidate at Department of Mechanical and Industrial Engineering.

Operations of complex technical systems such as railways networks, offshore oil and gas platforms, or autonomous cyber physical systems are subject to uncertainties, making the system drifting from its regular operations. Maintenance interventions may prevent incidents and accidents, yet also with costs, induced down times, and must therefore be optimized. It would be possible to perform “on demand” maintenance, via health monitoring of components, devices, or subsystems. The PhD position consists in studying concepts, methods, and tools to assess the performance of maintenance policies in view of optimizing them.

More specifically, the objective is to explore what can be done by: (1) Designing stochastic models to represent the dynamics of systems and maintenance policies.

(2) Performing Monte-Carlo simulations on these models to assess the values of key indicators characterizing the performance of maintenance policies. (3) Using advanced reinforcement learning and other AI techniques to improve the latter.

The PhD candidate is expected to design and apply the innovative reinforcement learning and other AI techniques to a new application area, namely maintenance optimization and more specifically the optimization of maintenance policies represented by stochastic models and assessed by means of discrete event simulations.

You will report to Professors.

Duties of the position

  • take part in the mandatory PhD research education program
  • conduct independent research and publish the result in recognised scientific journals
  • participate actively in the series of PhD seminars

Required selection criteria

  • you must have a professionally relevant background in Reliability, Availability, Maintainability and Safety or in Project Management or in Computer Science/Data Science or in Applied Mathematics
  • your education must correspond to a five-year Norwegian degree programme, where 120 credits are obtained at master's level 
  • you must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale.

The application and supporting documentation to be used as the basis for the assessment must be in English or Norwegian

Publications and other scientific work must follow the application. Please note that your application will be considered based solely on information submitted by the application deadline. You must therefore ensure that your application clearly demonstrates how your skills and experience fulfil the criteria specified above.

The application must include: 

  • CV and certificates
  • transcripts and diplomas for bachelor's and master's degrees. If you have not completed the master's degree, you must submit a confirmation that the master's thesis has been submitted.
