System performance analysis of complex systems with failure dependence
(Doctoral theses at NTNU;2024:113, Doctoral thesis, 2024)Many technical systems are becoming more and more complex, consisting of multiple components and prone to failure dependences. Within such systems with failure dependences, the failure of a component or some components may ... -
System Thinking, Evaluations and Learning - Experience from Road Construction Megaproject in Algeria
(Journal article; Peer reviewed, 2018)Ex-post evaluation is starting to be recognized in the Algerian different government institutions (e.g., ministries); and evaluation is becoming part of any program or project for two main reasons, justify the legitimacy ... -
Systematisering av kontinuerlig erfaringsoverføring i prosjektbaserte organisasjoner
(Master thesis, 2020)På grunn av byggeprosjekters egenart og midlertidige karakter er erfaringsoverføring i og mellom byggeprosjekter utfordrende å systematisere. Dersom bedrifter mislykkes i å strukturere effektiv erfaringsoverføring kan de ... -
Systematisk ferdigstillelse og VDC i byggeprosjekter
(Master thesis, 2022)Abstract will be available on 2025-09-11 -
Systems Engineering and Lean Product Development in Ship Design
(Master thesis, 2010)The goal of this master thesis is to generate knowledge about integrating best practices from systems engineering and lean product development into ship building. There is a need to develop product development processes ... -
Systems engineering for the subsea oil & gas industry – requirements elicitation through semantically aware technologies – a quantitative assessment
(Doctoral theses at NTNU;2018:251, Doctoral thesis, 2018)From the year 2000 through to 2016, no floating production storage and offloading (FPSO) projects were delivered on time or on budget. This straightforward but astonishing reality highlights the challenges of requirements ... -
A Systems Engineering Framework for Bioeconomic Transitions in a Sustainable Development Goal Context
(Peer reviewed; Journal article, 2020)To address sustainable development goals (SDGs), national and international strategies have been increasingly interested in the bioeconomy. SDGs have been criticized for lacking stakeholder perspectives and agency, and for ... -
Systems performance analysis of Oslo’s water and wastewater system
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:50, Doctoral thesis, 2011)Introduction: An advanced urban water and wastewater network – from the source of raw water to the sink for the treated effluent wastewater – is, to say the least, a complex one. The interdependencies and interrelationships ... -
Systems-Theoretic Process Analysis (STPA) Applied to the Operation of Fully Autonomous Vessels
(Master thesis, 2018)The objective of this master thesis is to assess the feasibility of using the STPA for hazard identification and assessment of complex and fully autonomous operating systems. As a continuous work from autumn 2017, this ... -
T-stress effects on fatigue crack growth – Theory and experiment
(Journal article, 2018)The effects of specimen geometry on the fatigue crack growth rate and the number of elapsed cycles have been investigated experimentally and theoretically for Al 7075-T6 using four different cracked specimens with positive ... -
Tactical and Operational Issues in a Hybrid MTO-MTS Production Environment: The Case of Food Production
(Chapter, 2013)Hybrid production environments that combine MTO and MTS strategies have emerged to enable production systems to better respond to changes in consumer and market demand. This paper discusses some of the tactical and operational ... -
Taguchi Optimization of Parameters for Feedstock Fabrication and FDM Manufacturing of Wear-Resistant UHMWPE-Based Composites
(Peer reviewed; Journal article, 2020)It is believed that the structure and properties of parts fabricated by additive (i.e., non-stationary) manufacturing are slightly worse compared to hot pressing. To further proceed with improving the quality of Fused ... -
Tailoring Biocomposites with Reduced Water Uptake for 3D Printing
(Master thesis, 2017)In this study, two different grades of bioPE, with a varying melt flow index (MFI) were tested for making biocomposites reinforced with wood fibre. A low MFI was found to be more adequate for the manufacturing. Filaments ... -
Takt-time control in high-mix/low-volume production
(Master thesis, 2015)Purpose The purpose of this thesis is to develop a spreadsheet tool for takt planning in a high-mix/low-volume (HMLV) environment. Ultimately, the objective is to develop tool that the production planner can use to test ... -
Tangential strain‐based criteria for mixed‐mode I/II fracture toughness of cement concrete
(Journal article; Peer reviewed, 2018)Experimental and theoretical works are performed on the mixed‐mode I/II brittle fracture of cement concrete tested by edge cracked semicircular bend specimens. Theoretical background of the traditional fracture criteria ... -
Tape winding angle influence on subsea cable sheathing fatigue performance
(Peer reviewed; Journal article, 2020)A fundamental component of subsea power cables is the thin galvanized steel tape winded around the dielectric and sheathing layer in order to prevent permanent thermal cycling induced deformation. The pressure state induced ... -
Task Programming of Redundant Industrial Robots: A Virtually Extended Null Space Formulation Verified Through Obstacle Avoidance
(Master thesis, 2012)Industrial robots are an important part of modern automation and are used in a variety of applications such as handling, welding, painting and assembling. They have normally six degrees of freedom to provide an arbitrary ... -
A Taxonomy for Engineering Change Management in Complex ETO Firms
