Sukon Wu is a PhD candidate at the chair of Maintenance Engineering within the department of Design, Production and Management. He did his bachelor in Industrial Management at the University of applied sciences Windesheim in Zwolle (The Netherlands) and his Master in Business Administration at the University of Twente (The Netherlands).



Failure Mode Effect and Criticality Analysis (FMECA) is a method that reveals the most critical parts in a system. In combination with Reliability Centered Maintenance (RCM) logic, maintenance programs can be defined for the assets of an organisation. Methods such as Root-Cause Analysis (RCA) are used to serve as input for improvements in design, operations or maintenance. The current problem with FMECAs and maintenance programs is that they are generally performed a single time in organisations and become static documents with little to no improvement.

This research is part of a larger research project (3 PhD students). The other 2 PhDs focus on prediction models in order to perform just-in-time maintenance. One research does so by analysing the data collected by existing sensors on the railway infrastructure. The other research focusses on physical failure modelling, by using several variables to predict failure. This research aims to combine both models in order to optimise the maintenance planning and to give direction in order to further improve the models.

The research project aims at the development of robust improvement strategies in order to optimise maintenance plans. It does so by re-using RCM and FMECAs and improving data registration and collection. Based on the evidence in the data maintenance plans can be improved.

This research is funded by Strukton Rail (part of Strukton), who are responsible for the maintenance of a large part of the Dutch railway infrastructure, as well as parts of the railway infrastructure of several other countries. The research is carried out together with prof. Leo van Dongen, and dr. Jan Braaksma.
