A Data-Driven Approach for Fault Classification of a Manufacturing Process
(Master thesis, 2022)Fault diagnosis is among the most crucial steps in maintenance strategies to sustain the health of machine tools. Traditionally, fault diagnosis was performed based on engineers' vast expertise and technical understanding. ... -
A data-driven approach to improve control room operators' response
(Peer reviewed; Journal article, 2021) -
A data-driven method based on deep belief networks for backlash error prediction in machining centers
(Journal article; Peer reviewed, 2017)Backlash error occurs in a machining center may lead to a series of changes in the geometry of the components and subsequently deteriorate the overall performance of the equipment. Due to the uncertainty of mechanical wear ... -
A DBN-based risk assessment model for prediction and diagnosis of offshore drilling incidents
(Journal article; Peer reviewed, 2016)Drilling operations of offshore oil and gas fields are characterized by high technical complexity, high risks, and high costs, since they are always in harsh environments with complicated geological factors. Lost circulation ... -

A deep learning approach for anomaly detection based on SAE and LSTM in mechanical equipment
(Journal article; Peer reviewed, 2019)Anomaly in mechanical systems may cause equipment to break down with serious safety, environment, and economic impact. Since many mechanical equipment usually operates under tough working environments, which makes them ... -
A Degrading Element of Safety-instrumented Systems with Combined Maintenance Strategy
(Chapter, 2019)Safety-instrumented systems (SISs) are widely used to prevent hazardous events. The mechanical actuator subsystem in a SIS can become more vulnerable with time due to progressive degradation mechanisms, such as erosion, ... -
A diagram for capturing and predicting failure locations in notch geometries produced by additive manufacturing
(Journal article; Peer reviewed, 2020)In a recent work by the authors Solberg and Berto (2019), as-built notch geometries of Inconel 718 produced by selective laser melting was investigated under fatigue loading. One of the findings was that fatigue did not ... -
A Digital Product-Offering Platform in Construction Supply Chains: An Exploratory Study of the Potential Effects on a Pipe Manufacturer’s Business Model
(Master thesis, 2019)En digital produktplattform for bygg- og anleggsnæringen er under vurdering for å forbedre synlighet og koordinasjon i en verdikjede mellom rørprodusent og entreprenør på anleggsprosjekt. Formålet med denne masteroppgaven ... -
A dynamic Bayesian network approach for prognosis computations on discrete state systems
(Journal article, 2017)The maintenance optimization of complex systems is a key question. One important objective is to be able to anticipate future maintenance actions required to optimize the logistic and future investments. That is why, over ... -
A Fatigue Assessment Methodology for Notched Components Containing Defects
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:224, Doctoral thesis, 2007)A probabilistic fatigue assessment tool, P•FAT, directly applicable to the results from a standard finite element stress analysis has been developed. The fatigue assessment tool consist of two deterministic fatigue assessment ... -
A Finite Element Tool for Investigation of Vortex-Induced Vibration of Marine Risers
(Master thesis, 2014)Vortex-induced vibration (VIV) is a major design issue for all deep-water riser systemsoperating in regions where severe sea currents can be expected. This highly complexphenomenon has resulted in a great deal of experimental ... -
A Framework for Continuous Design Reuse Management Supported by an Option-Based Reuse Approach
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:139, Doctoral thesis, 2007)This PhD thesis aims to address the problem of missed design reuse opportunities across consecutive products in industry. The research specifically targets the perceived knowledge gap regarding conceptual tools for ... -
A framework for ICT-enabled real-time production planning and control
(Journal article; Peer reviewed, 2014)This paper aims to develop a conceptual framework for real-time production planning and control (PPC). Firstly, we discuss the most prominently applied contemporary information and communication technologies for PPC. ... -
A Framework for Identification and Management of Project Success: In Water and Sewage agency of Oslo Municipality
(Master thesis, 2011)It is inconceivable to have a city without water. Cities and water are inextricably linked.Oslo Water and Sewage agency (VAV) is a municipally-run utility responsible for the supply and treatment of potable water and ... -
