    • A practical guideline for human error assessment: A causal model 

      Ayele, Yonas Zewdu; Barabadi, Abbas (Konferansebidrag; Conference object, 2017-12-12)
      To meet the availability target and reduce system downtime, effective maintenance have a great importance. However, maintenance performance is greatly affected in complex ways by human factors. Hence, to have an effective maintenance operation, these factors needs to be assessed and quantified. To avoid the inadequacies of traditional human error assessment (HEA) approaches, the application of ...

    • Prediction of remaining useful life (RUL) of Komatsu excavator under reliability analysis in the Weibull-frailty model 

      Ghomghaleh, Awat; Khaloukakaie, Reza; Ataei, Mohammad; Barabadi, Abbas; Qarahasanlou, Ali Nouri; Rahmani, Omeid; Beiranvand Pour, Amin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)
      It is an essential task to estimate the remaining useful life (RUL) of machinery in the mining sector aimed at ensuring the production and the customer’s satisfaction. In this study, a conceptual framework was used to determine the RUL under the reliability analysis in a frailty model. The proposed framework was implemented on a Komatsu PC-1250 excavator from the Sungun copper mine. Also, the ...

    • Recoverability modeling of power distribution systems using accelerated life models: Case of power cut due to extreme weather events in Norway 

      Rød, Bjarte; Barabadi, Abbas; Naseri, Masoud (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)
      Today’s societies rely on electric power distribution systems. Recent weather events have illustrated that the loss of such service can lead to severe consequences for societies and stakeholders. Hence, to reduce the impact of such extreme events on infrastructure systems and limit the associated losses, it is crucial to design infrastructure that can bounce back and recover rapidly after disruptions ...

    • Reliability modelling on two-dimensional life data using bivariate weibull distribution: with case study of truck in mines 

      Yuan, Fuqing; Barabadi, Abbas; Lu, Jinmei (Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
      An engineering system can exhibit two- or multi-dimensions in its lifetime. As the classical univariate distribution cannot model this multi-dimensional characteristic, it is necessary to extend it to multivariate distribution in order to capture the multi-dimensional characteristics. This paper proposes a bivariate Weibull distribution that combines two classical Weibull models by a common exponent. ...

    • Resilience Assessment of Wind Farms in the Arctic with the Application of Bayesian Networks 

      Mustafa, Albara; Barabadi, Abbas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-22)
      Infrastructure systems, such as wind farms, are prone to various human-induced and natural disruptions such as extreme weather conditions. There is growing concern among decision makers about the ability of wind farms to withstand and regain their performance when facing disruptions, in terms of resilience-enhanced strategies. This paper proposes a probabilistic model to calculate the resilience of ...

    • Resilience Assessment: A Performance‐Based Importance Measure 

      Nouri, ali; Zamani, Ali; Barabadi, Abbas; Mokhberdoran, Mahdi (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-12)
      The resilience of a system can be considered as a function of its reliability and recoverability. Hence, for effective resilience management, the reliability and recoverability of all components which build up the system need to be identified. After that, their importance should be identified using an appropriate model for future resource allocation. The critical infrastructures are under dynamic ...

    • The Resilience of Critical Infrastructure Systems: A Systematic Literature Review 

      Mottahedi, Adel; Sereshki, Farhang; Ataei, Mohammad; Nouri, ali; Barabadi, Abbas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-12)
      Risk management is a fundamental approach to improving critical infrastructure systems’ safety against disruptive events. This approach focuses on designing robust critical infrastructure systems (CISs) that could resist disruptive events by minimizing the possible events’ probability and consequences using preventive and protective programs. However, recent disasters like COVID-19 have shown that ...

    • Risk Assessment of Operation and Maintenance of Wind Turbines in the Arctic [poster] 

      Mustafa, Albara Mohamad Yazid Faisal; Barabadi, Abbas (Conference object; Konferansebidrag, 2019)

    • Risk assessment of wind farm development in ice proven area 

      Mustafa, Albara; Barabadi, Abbas; Markeset, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      There many risks associated with wind farms operating in cold harsh areas, a number of these risks is caused by icing. Atmospheric and super-structure icing can cause ice accretion on wind turbines’ structure, and lead to public safety risks caused by ice throw and the failure of wind turbine’s components. Other risks can affect wind farm’s maintenance crew and their activities. Such risks are ...

    • Spare Part Management Considering Risk Factors 

      Barabadi, Reza; Ataei, Mohammad; Khalokakaie, Reza; Barabadi, Abbas; Nouri, ali (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-01)
      The spare parts provision is a complex process, which needs a precise model to analyze all factors with their possible effects on the required number of spare parts. The required number of spare parts for an item can be calculated based on its reliability performance. Various factors can influence the reliability characteristics of an item, including operational environment, maintenance policy, ...

    • Spare Part Transportation Management in High North 

      Ayele, Yonas Zewdu; Barabadi, Abbas; Markeset, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The demanding physical conditions of the Arctic, remote location, and uncertainty regarding the travel time can both heighten the challenges related to transportation of spare part in the region. Managing to get the appropriate path for transportation of spare parts for oil and gas industries in the region, is one of the major and demanding tasks. In this paper we develop the concept of ...

    • Uncertainties in Managing Atmospheric Icing on Power Lines 

      VAHHABI, MOHSEN; Barabadi, Abbas; Barabady, Javad; Nouri, Ali (Chapter; Bokkapittel, 2023)
      Icing affects the infrastructure dramatically, especially in the cold region. Therefore, applying effective ice disaster management (IDM) to provide a systematic approach to dealing with atmospheric icing on power lines is essential. It includes preparedness, response, recovery, learning, risk assessment, and prevention. Integral to this management is the accurate prediction and modeling of icing, ...
