Throughout the operational lifetime of ICs, harsh environmental conditions including extreme high or low temperature, humidity, shock, and stress tend to cause intrinsic physical degradations, which results in significant variations of long-life EMC performance of IC device. Consequently, ensuring along with maintaining electromagnetic robustness (EMR) and integrating IC reliability throughout their whole lifetime period is a key challenge that needs to be addressed. The purpose of this paper is to conduct a comprehensive state-of-the-art study on developing accurate immunity and emission models of ICs focusing on quantitative evaluation of experimental characterization based on various IC EMC measurement methods under various ageing accelerated life tests. Producing accurate transient EMC models help not only estimate EMC immunity and emission levels of ICs but also allows determining different failure types and mechanisms due to radio frequency disturbance when applied to IC model structures. This paper presents a few recent researches on the conducted pulse immunity as well as emission models for ICs based on the IEC standard models, showcasing the electric fast transient (EFT) simulations and measurements applied on different IC pins considering the ageing impact. Previous studies demonstrated the importance of the ageing on the EMC performance of ICs depending on the ageing stress parameters. Future perspective of the current study would involve proposing and implementing predictive reliability model for the IC during its entire lifetime under accelerated life tests.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134098849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst methodologies have been proposed to aid decision makers with optimal routeing and mitigation strategies for these cables, such methods require definition of drag probabilities which thus far have not been empirically validated. In this paper, we present a framework through which anchor drag probabilities can be calculated through analysis of historical vessel traffic data and environmental conditions. Drag distances, probabilities and causal influences of conditions are shown through comparison of three million hours of vessel anchoring exposure. We show that the wind speed and wave height are the most significant factors for calculating the likelihood of anchor dragging, but other factors omitted in this study may also be influential. The results show that the method can improve the validity of Cable Burial Risk Assessments, supporting navigation authorities and developers with mitigating the risks to subsea cables.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132521140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The core of such trend lies with the integration of failure mechanisms in the modelling of systems since the very design phase, focusing on the ability to efficiently absorb and rapidly respond to threats rather than merely avoid them. This is expected to overcome the limitations of traditional design-against-failure approaches, whose efficiency is often undermined by the strong uncertainty associated with rare or hardly predictable hazards. However, the potential advantages such a theoretical shift delivers have not yet been matched by the availability of adequate numerical tools and methodologies targeting the challenges associated with resilience analyses. The current literature and engineering practice lack of a widely agreed upon methodology for the assessment of systems resilience, or even for the definition of its metrics. This study proposes a novel approach for the estimation of the dynamic response of complex systems to safety-threatening perturbations, aiming at providing a solid base for the evaluation of system resilience. The framework proposed relies on the use of Petri nets to capture both the physics of the processes entailed by the system operation and its interaction with the technological installation. The framework is applied to a case-study focusing on the response of a CANDU nuclear reactor to cyber incidents hindering the correct operation of the reactor control system and hence resulting in a loss of regulation threatening the structural integrity of the nuclear fuel.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134222770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since then, research has made considerable advances in the capabilities of analytical techniques applicable to safety critical systems. Technology has also advanced and system designs, their operation conditions and maintenance strategies are now significantly different to those of the 1970s. This paper presents an overview of a new methodology developed, retaining the traditional ways of expressing system failure causality, which aims to develop the next generation of risk assessment methodologies. These evolved techniques, appropriate to meet the demands of modern industrial systems, aim to overcome some of the limitations of the current approaches. These new tools and techniques will seek to retain as much of the current methodology features as possible to reduce the learning curve for practitioners and increase the chances of acceptance. The new approach aims to increase the scope of event tree/fault tree analysis through the incorporation of Petri net, Markov model, and binary decision diagram-based methodologies. Use of these techniques incorporates features such as: non-constant failure rates, dependencies between component failure events, and complex maintenance strategies to boost the capabilities of the methods. In addition, it considers dedicated routines to analyse the accident risk of transport systems formulated as phased mission models. This type of modelling is demonstrated through the application to an aeronautical system, where the system is modelled as a mission consisting of a series of phases. Mission success requires the successful completion of each of the phases. This approach allows the requirements for success (and therefore failure) to differ from one phase to another. It is also possible to model scenarios whereby a system fault that occurs in one phase of a mission may not affect the system until a later phase of the mission.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134298714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human error is often reported as a contributor to maritime and aviation accidents. Therefore, the implementation of human-informed design considerations is essential to improve safety and operational performance in both sectors, especially in the maritime sector, where there is a lack of an established framework to systematically consider human factors at the design stage. Therefore, the SAFEMODE project brings together key experts from both aviation and maritime sectors to address this important gap. The SAFEMODE project aims to deliver a framework that includes human factors considerations and enables designers to make risk-informed decisions. The methodological approach of SAFEMODE builds upon four areas: the collection and analysis of accident data; the development of a toolkit for human performance assurance, the development of Human Factors-based risk models and the creation of a framework to support risk-informed design. The type of safety events considered in SAFEMODE for both domains includes collision and grounding for the maritime sector, and runway collision, taxiway collision and wake vortex during en-route flight phase for the aviation sector. This paper will provide an insight into the efforts conducted as part of the SAFEMODE project to assess the human contribution to risk and the benefits of applying these models to support risk-informed decisions in design and operations.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"3 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114088751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Restrictions on the public life and lockdowns of different characteristics define the life in many countries. This paper focuses on the first year of the COVID-19 pandemic (01-28-2020 to 01-15-2021). As a transfer of methods used in reliability engineering for analyzing occurrence of infection, Weibull distribution models are used to evaluate the spreading behavior of COVID-19. Key issues of this study are the differences of spreading behavior in first and second pandemic phase and the various impacts of lockdown measures with different characteristics (hard, light). Therefore, the occurrence of infection in normed time periods with and without lockdown measures are analyzed in detail on the example of Germany representing the spreading behavior in Europe. Additional information in comparison to classical infection analyzes models like SIR model is generated by the application of Weibull distribution models with easy interpretable parameters and the dynamic development of COVID-19 is outlined. In a further step, the occurrence of infection of COVID-19 is put into the context of other common infectious diseases in Germany like Influenza or Norovirus to evaluate the infectiousness. Differences in spreading behavior of COVID-19 in comparison to these well-known infectious diseases are underlined for different pandemic phases.","PeriodicalId":187633,"journal":{"name":"Proceedings of the 31st European Safety and Reliability Conference (ESREL 2021)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129196223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
