Tets, Evan (author)In this day and age sustainability is becoming increasingly important. Even though the airline business is not the first thing which comes to mind when regarding sustainability there are huge efforts in play to extend the life of airplanes and its corresponding components. This is done via remanufacturing. Remanufacturing can here be defined as:...master thesis 2022

Kalf, Hilt (author)Aircraft LRU (Line Replaceable Unit) MROs (Maintenance, Repair Organization) struggle to meet service levels. To stay competitive, literature describes two strategies; increasing contracted fleet size and not reaching projected repair turn around times. Besides these two strategies, literature does not describe the use of triple echelon order...master thesis 2021

Sulyman, Peywand (author)The aviation Maintenance, Repair and Overhaul (MRO) industry faces an enormous growth due to the increasing air traffic. To accommodate this growth and increase efficiencies of processes it is required to increase the transparency of demand in the Supply Chain (SC). Research into predicting demand in the MRO industry have mainly been focused on...master thesis 2020

van Vuuren, Stijn (author)Engine performance diagnostics play a major role in keeping track of gas turbine condition and performance and identification of possible errors or faults. One of the key performance indicators used in engine performance diagnostics is the Hot Day Exhaust Gas Temperature Margin (EGTM). Ambient humidity affects the EGTM, however humidity is not...master thesis 2019

Röell, Bastiaan (author)After maintenance, turbofan engines are subjected to a performance acceptance test in an indoor test-cell to demonstrate that corrected performance thresholds are met. The same indicators are also monitored after on-wing installation. Despite corrections for operation conditions, differences are observed between test-cell and subsequent on-wing...master thesis 2019

Bosdijk, Nicole (author)Aircraft component maintenance, repair, and overhaul (MRO) outsourcing is a rather new phenomenon. Nowadays, component support solutions that are flexible with predictable cost are pursued. In other words, the time to restore and cost of MRO are aimed to be minimised. This research project is collaboration with one of the worlds leaders in...master thesis 2019

Peschier, Daan (author)Aircraft base maintenance consists of hundreds of tasks including preventive, corrective and modification tasks which have to be scheduled to a few check moments per year. The allocation of tasks to checks represents a complex scheduling problem due to the constraints involved. A mixed integer linear programming model was developed to optimize...master thesis 2019

van den Hoed, Marielle (author)Due to complex nature of aircraft heavy maintenance checks, achieving process stability is difficult. Literature suggests that this stability can be obtained by separating routine and non-routine work, and focusing on quick identification of non-routine tasks by completing inspection tasks early in the check. Current task planning methods show...master thesis 2018

Conijn, J. (author)Increasing competition in today’s markets leads to an increasing need for companies to be competitive. One factor that affects how competitive companies can be, is how innovative they are. Companies therefore want to be innovative, which can be challenging. One way of being innovative is to use innovations created by others. When two companies...master thesis 2016
