We consider a maintenance service provider that services geographically dispersed customers with its local service engineers. Traditionally, when a system failure is reported, a service engineer makes a diagnostic visit to the customer's location to perform corrective maintenance. If spare parts are required, they are ordered and a second...

Shipping companies aim to reach the climate goals by following the rules from the International Maritime Oranization (IMO), which includes reducing Scope 3 emissions. Maintenance is a great contributor to the Scope 3 emissions of a shipping company, especially the transportation of spare parts. The current state-of-the-art supply chain...

This graduation project delves into the use of Additive Manufacturing (AM) to produce spare parts through a case study of vacuum cleaners. Waste from Electrical and Electronic Equipment (WEEE), including products like vacuum cleaners, challenges the European Union’s (EU) sustainability goals. In 2020 alone, the EU collected an estimated 12.4...

Europe’s offshore wind capacity is expected to reach 450 GW by 2050, meeting 30% of Europe’s electricity demand. With the increase of installed capacity, the costs invested in O&M will also increase significantly considering O&M cost is one of the biggest contributors to life cycle costs. The improvement of O&M management for...

Spare parts availability is crucial for extending the life of consumer products. However, long-term availability could lead to high stocks of spare parts, which might not be used. Instead, on-demand manufacturing of spare parts with additive manufacturing (AM) is a promising alternative. This paper presents a method to evaluate parts on their...

Thanks to Industry 4.0 technologies, predictive algorithms can provide advance demand information on spare parts demand. Understanding how the goodness of predictions affects on-hand inventory and costs is important for decision makers before integrating these models into existing systems. We consider a spare parts inventory problem for multiple...

The availability and storage of spare parts are the main barriers to product repair. One possibility would be to 3D print spare parts, which would also enable the repair of products not intended to be repaired. Besides manufacturers, 3D printing spare parts is an interesting option for self-repair by consumers. However, the digitisation of...

The Sharepair project aims to decrease the waste of electronic and electric consumer products and increase their useful life, by supporting repair communities and scaling up citizen repairs through digital tools. One of the focus areas of this project is to support the discovery or manufacturing of spare parts. With a 3D CAD model of a part and...

This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is an iterative process in which the part is analysed, redesigned,...

The master thesis project explores the spare parts business due to the evidence available on how well it contributes to the revenues and profits of firms. With increasing product variety, shorter product lifecycles and market competition, it is necessary for firms to supply spare parts to customers for keeping the products functional....

To better govern inventory control of spare parts in tandem with scheduling of maintenance operations in a railway setting, a Railway Spare Inventory & Maintenance Scheduling (R-SIMS) model is developed. To suit the railway industry setting the model includes an inventory control strategy which envokes continuous monitoring and a reorder...

For the shared mobility service providers, it is essential to have an economic operation and therefore, it is necessary to maximise their fleet utilisation. Of influence on the latter is the availability of the spare parts. The topics for which spare part forecasting research is already performed are different in several ways compared to the...

This study provides new insights in the problem of lumpy aircraft spare parts demands by incorporating new drivers that have an impact on the failure patterns of aircraft components. The study introduces a model and presents corresponding results that obtains component failure characteristics based on data from an aircraft manufacturer. A Monte...

The competition in the airline industry has rapidly increased during the last decades, especially with the entrance in the market of low-cost carriers. The high costs incurred in Maintenance, Repair and Overhaul (MRO) activities are generating a great interest in the improvement of maintenance operations as a way to stay competitive in the...

This project focuses on enhancing the accessibility of 3D printing for repairers by designing a system in which repairers can collaborate with makers. Repair has become rare in societies with an abundance of cheap goods. However in recent years repair is making a gradual comeback in western culture. Citizen repair initiatives such as Repair...

KLM Engineering & Maintenance Component Services manages a spare part pool. They are responsible for ensuring spare part availability for their contracted customers. For rotable spare parts, which are interchangeable and repairable, the supply chain is closed-loop. As the demand for spare parts is sporadic, with large zero demand periods, a...

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...

Due to the complexity of aircraft spare part management, the aviation supply chain and ecosystem are not deemed as transparent as desired. As a result, participants face additional cost of communication and compliancy as proprietary component data is not made immediately accessible. To solve these problems, Maintenance, Repair and Overhaul (MRO)...
