1. Demystifying the effectiveness in design of production systems - Investigating the coupling between acquisition and maintenance of equipment
Abstract : The purpose of the design of production systems is to create systems that perform according to set targets. With the paradigm shift towards electrification and digitalisation, manufacturing engineers in the heavy truck powertrain industry face several unexplored challenges; in the products for which they are designing production, in the equipment they are purchasing to realise production systems, and finally, in the digitalisation impact on engineering processes.

2. Very high cycle fatigue of high performance steels
Abstract : Many engineering components reach a finite fatigue life well above 109 load cycles. Some examples of such components are found in airplanes, automobiles or high speed trains. For some materials the fatigue failures have lately been found to occur well after 107 load cycles, namely in the Very High Cycle Fatigue (VHCF) range. READ MORE

3. Leveraging supplier material data to inform LCA modelling and resource assessment in the automotive industry
Abstract : This thesis investigates the application of supplier material composition data from the automotive industry's International Material Data System (IMDS) to inform sustainability assessments. A methodology is developed to systematically extract and process IMDS data for use in life cycle assessment (LCA) modelling. READ MORE

4. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs
Abstract : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. READ MORE

5. Assessing Mineral Resource Scarcity in a Circular Economy Context
Abstract : Due to humanity’s dependence on metal resources there are growing concerns regarding impacts related to their potential scarcity, both for current and future generations. The vision of a more circular economy suggests that extending the functional use of metals through measures aiming for resource-efficiency (RE) such as increasing technical lifetime, repairing and recycling could reduce mineral resource scarcity.
