Khakzad, Sina (author), Yang, M. (author), Lohi, Ali (author), Khakzad, N. (author)Oil and gas pipelines play a key role in the safe and efficient delivery of energy resources around the world. Crude oil by itself is not corrosive, but oil extracted from geological reservoirs is accompanied by varying amounts of water and acidic gases such as carbon dioxide (CO2), which can form a corrosive combination. Estimating the...journal article 2022

Abrishami, S. (author), Khakzad, N. (author), Hosseini, Seyed Mahmoud (author), van Gelder, P.H.A.J.M. (author)Success Likelihood Index Model (SLIM) is one of the widely-used deterministic techniques in human reliability assessment especially when data is insufficient. However, this method suffers from epistemic uncertainty as it extremely relies on expert judgment for determining the model parameters such as the rates and weights of the performance...journal article 2020

Cheraghi, Morteza (author), Eslami Baladeh, Aliakbar (author), Khakzad, N. (author)Hazard and Operability analysis (HAZOP) is a popular technique for hazard identification and risk ranking in hazardous facilities. Conventional HAZOP, however, has some drawbacks: (i) it considers a limited number of risk factors, i.e., only the frequency and the severity of hazards; (ii) it assumes equal weights for the risk factors, thus...journal article 2019

Cincotta, Salvatore (author), Khakzad, N. (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author)Domino effects triggered by fire can cause extremely severe damages to the chemical and process plants. In the need of a more effective prevention of fire domino effects, the present study focuses on firefighting which has received less attention compared to passive and active fire protection systems. Considering both the vulnerability and...journal article 2019

Baladeh, Aliakbar Eslami (author), Khakzad, N. (author)Complex networks play a vital role in reliability analysis of real-world applications, demanding for precise and accurate analysis methods for optimal allocations of cost and reliability. Since the configuration of a system may change with every feasible solution of cost allocation optimization equation, finding the best arrangement of the...conference paper 2019

Zarei, Esmaeil (author), Yazdi, Mohammad (author), Khakzad, N. (author), Reniers, G.L.L.M.E. (author)Risk analysis in process systems is very important to design effective strategies for preventing and mitigating potential major accidents. Although conventional techniques as Bow-tie (BT) have widely been used in risk assessment of process systems, they fall short in effectively modelling epistemic uncertainty which is prevailing in risk...journal article 2019

Chen, C. (author), Reniers, G.L.L.M.E. (author), Khakzad, N. (author)Past accident surveys reveal that loading and unloading operations (LUOs) are responsible for 11% of fire-related domino accidents. This study investigates the domino accidents during LUOs in the last two decades and identifies the main causes and features of these domino effects. An index-based approach is proposed to assess these domino...journal article 2019

Smith, Roland (author), van de Loo, Jasper (author), van den Boomen, M. (author), Khakzad, N. (author), Jan van Heck, Geert (author), Wolfert, A.R.M. (author)Water treatment plants (WTPs) are characterised as complex configurations of repairable and deteriorating components. Previous studies have mainly focused on the average or steady-state availability of such systems while ignoring inherent characteristics like degradation. The current research proposes a two-level hierarchical model for long-term...journal article 2019

Eslami Baladeh, Aliakbar (author), Cheraghi, Morteza (author), Khakzad, N. (author)Optimal selection of safety measures (SMs) is a challenging task for safety managers due to its importance, complexity, and incapability of traditional approaches in considering all the aspects of SMs optimal selection. Sophisticated mathematical models can be used to overcome the limitations of traditional approaches. However, setting the...journal article 2019

Khakzad, N. (author)System safety and reliability assessment relies on historical data and experts opinion for estimating the required failure probabilities. When data comes from different sources, be it different databases or subject domain experts, the estimation of accurate probabilities would be very challenging, if not impossible, and subject to high epistemic...journal article 2019

Chockalingam, S. (author), Pieters, W. (author), Teixeira, Andre M. H. (author), Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)Because of modern societies' dependence on industrial control systems, adequate response to system failures is essential. In order to take appropriate measures, it is crucial for operators to be able to distinguish between intentional attacks and accidental technical failures. However, adequate decision support for this matter is lacking. In...conference paper 2019

Khakzad, N. (author), Landucci, Gabriele (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author), Pasman, HJ (author)The propagation of fire-induced domino effects in chemical plants largely depends on the primary fire scenario, on separation distances between the units, and on the presence of fire protection barriers. Passive and active safety barriers are widely employed to prevent or delay the initiation or propagation of domino effects. In the present...journal article 2018

Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)Natech is a technological accident which is triggered by a natural disaster. Increasing frequency of natural disasters along with an increasing growth of industrial plants are bound to increase the risk of Natechs in the future. Due to a lack of accurate field observations and empirical data, risk assessment of Natechs has largely been...conference paper 2018

Khakzad, N. (author)The performance of fire protection measures plays a key role in the prevention and mitigation of fire escalation (fire domino effect) in process plants. In addition to passive and active safety measures, the intervention of firefighting teams can have a great impact on fire propagation. In the present study, we have demonstrated an application...journal article 2018
