Sun, Hao (author), Yang, M. (author), Wang, Haiqing (author)Reliability-based and risk-based methods for directing maintenance activities play a critical role in ensuring system safety and reducing unnecessary downtime. Those methods focus on preventive maintenance to avoid component failures and are applicable before unexpected disruptions occur. However, when disruptions are unavoidable, more attention...journal article 2022

Chowdhury, Shaiful (author), Holmes, Reid (author), Zaidman, A.E. (author), Kazman, Rick (author)Evaluating and predicting software maintenance effort using source code metrics is one of the holy grails of software engineering. Unfortunately, previous research has provided contradictory evidence in this regard. The debate is still open: as a community we are not certain about the relationship between code metrics and maintenance impact....journal article 2022

Walraven, Marc (author), Vrolijk, Koos (author), Kothuis, B.L.M. (author)In several coastal regions around the world, movable storm surge barriers have been implemented to protect against flooding induced by storm surges and waves. These barriers often form an integral part of the coastal defense system. In urban deltas, they are mostly intended to protect urban and industrial interests, while providing access for...book chapter 2022

van Kessel, Paul J. (author), Freeman, Floris C. (author), Santos, Bruno F. (author)Airline maintenance task scheduling takes place in a disruptive environment. The stochastic arrival of corrective maintenance tasks and changes in both fleet and resource availability require schedules to be continuously adjusted. An optimal schedule ensures that all tasks are executed before their due date in both an efficient (at minimum...journal article 2022

Mars, Laura (author)In this thesis, a simulation cost model is presented that can be used to assess the cost-effectiveness of a selection of PdM programs. The proposed model combines a discrete event simulation (DES) model with a cost model. It is specifically designed to analyse the PdM programs for the vacuum compressor pumps at Duyvis. All the PdM programs...master thesis 2021

van Ingen, Floris (author), Geleijnse, Jan (author), Curzi, Fabio (author), Kingma, Pieter (author)On request of Royal Boskalis Westminster N.V. a comprehensive research was performed regarding emission free maintenance dredging in a harbour environment. The project site is the Maasmond at the port of Rotterdam. It covers an area of almost 10 km2 and, on average, a monthly volume of 400.000 cubic meters of sediment needs to be dredged. The...student report 2021

Boekweit, Stan (author)During operation aircraft brakes degrade due to wear. This degradation can be continuously monitored using brake degradation sensors. Using this monitored degradation data the remaining useful life of the brakes can be estimated by means of a prognostic model based on a Gamma probability distribution. Using the remaining useful life estimations...master thesis 2021

Guo, Y. (author), Markine, V.L. (author), Jing, Guoqing (author)Railway ballast beds bear cyclic loadings from vehicles and deteriorate due to ballast particle degradation (breakage and abrasion), ballast pockets (subgrade defects), fouling (or contamination) and plastic deformation of the beds. Ballast bed deterioration changes the ballast track geometry, which leads to uncomfortable rides, exacerbates...review 2021

Trepat Borecka, Jacob (author), Bešinović, Nikola (author)Highly utilized railway networks require regular infrastructure maintenance. Different track sections often need to be closed for entire days to carry out engineering works, which makes the regular timetables no longer feasible and thus adjusted railway services and temporary alternative services need to be planned. We introduce the...journal article 2021

Zomer, Jordi (author), Bešinović, Nikola (author), de Weerdt, M.M. (author), Goverde, R.M.P. (author)Due to increasing railway use, the capacity at railway yards and maintenance locations is becoming limiting to accommodate existing rolling stock. To reduce capacity issues at maintenance locations during nighttime, railway undertakings consider performing more daytime maintenance, but the choice at which locations personnel needs to be...journal article 2021
