“…By linking risk management and strengthening resilience, the protection of critical infrastructure is extended by the repressive part, i.e., the reaction to already occurring adverse events (NIAC 2009). However, current approaches in various areas focus only on assessing and strengthening critical infrastructure resilience (Alizadeh and Sharifi 2020;Argyroudis et al 2020;Quitana et al 2020;Li et al 2020;Shandiz et al 2020) even though resilience goes beyond traditional risk management (Petersen et al 2020). Therefore, it can be stated that there is currently no appropriate managerial tool that would explicitly deal with preventive measures for the protection of critical infrastructure elements.…”

“…For this reason, in recent years, particular attention has been paid to research into methods for assessing and strengthening critical infrastructure resilience, as resilience goes beyond traditional risk management (Petersen et al 2020). This fact is evidenced, in particular, by articles dealing with resilience in the context of entire cities or urban areas (Chen et al 2020;Li et al 2020;Lu et al 2020;Rehak et al 2019) of their transport systems (Argyroudis et al 2020;Machado-León and Goodchild 2017;Dvorak et al 2017) or individual urban networks (Alizadeh and Sharifi 2020;Liu and Song 2020;Quitana et al 2020;Shandiz et al 2020). These approaches are realistically applicable and contribute to strengthening the resilience of critical infrastructure, but do not allow for the early indication of resilience disruption.…”

Managerial decision making is an integral process used in public and private organizations. Critical infrastructure entities are a strategically significant group dependent on the quality of decision-making processes. They aim to provide services necessary to ensure state security and to satisfy basic human needs. The quality of decision making is an important factor in the management of these entities. The quality level is determined by many factors, the key of which is risk management. For this reason, it is necessary for the operators to minimize risks affecting the elements of the critical infrastructure through which these services are provided. Risk management is commonly used for this purpose, making it possible to assess and manage these risks. However, there is a specific group of threats that affects the resilience of these elements. The indication of these threats is not possible through common risk management. Therefore, it is necessary to develop specific scenarios of negative impacts and procedures for assessing their impact on the resilience of elements of the critical infrastructure. To this end, this conceptual article introduces an entirely new managerial decision-making process for indicating the resilience of critical infrastructure elements.

“…A generic parametric study is needed to capture the spatial variability of soil properties and geometry of the embankments, the results of which can later be applied to different scenarios in a vulnerability analysis of transport network systems. Fragility curves and other outcomes of the study related to the effects of model variables might serve as an input parameter to an integrated framework of a comprehensive study dealing with infrastructure or traffic network resilience [41,42] as well as overall societal flexibility to recover from a natural disaster. In addition, the outcomes of such studies enable a rapid assessment of vulnerability, which can serve as a starting point for a detailed analysis of critical embankments.…”

Fragility Assessment of Traffic Embankments Exposed to Earthquake-Induced Liquefaction

In this study, a vulnerability analysis of road and railway embankments to earthquake-induced liquefaction deformations was carried out. The result of the vulnerability analysis was a set of fragility curves that were obtained for several embankment and soil-profile geometries, as well as for the material properties of the liquefiable layer. The fragility curves were based on the numerical calculations obtained from FLAC 2D software in conjunction with the PM4Sand material model used for simulating the behavior of liquefaction-susceptible soils during dynamic shaking. The fragility analysis was performed using an incremental dynamic analysis approach considering a set of 30 ground motions and at least eight intensity levels. Permanent vertical displacement of the middle top point of the embankment was selected as the damage parameter, while the intensity measure was expressed in terms of peak ground acceleration at bedrock. Fragility curves were derived for three damage states, including minor, moderate and extensive damage, based on threshold values proposed in the literature. The influence of a single model variable was examined through comparison of the fragility curves.

“…The concept of regional resilience is mainly based on the concept of resilience. Based on the different understandings of the concept of resilience, scholars also have different definitions of regional resilience [31][32][33]. A region or country is a coupling system of resources, environment, economy, and society, and the process of regional development is the process of human utilization and transformation of nature.…”

Regional resilience refers to the resilience of a country or region against the ecological environment, social economy, and other internal and external natural factors and human factors in the process of development. When this resilience is lower than a certain critical threshold, the country or region will be in a fragile state. The comprehensive embodiment of ecological resilience, social resilience, and economic resilience of a country or region is regional resilience. Due to the wide range of countries along "the Belt and Road", differences in natural background conditions and stages of economic and social development among different countries lead to different degrees of vulnerability, and the improvement of resilience is conducive to reducing vulnerability. At the same time, the research on the measurement and differentiation characteristics of regional resilience is of considerable significance to solve the weak foundation of environmental management and the lack of ability to deal with climate change of "the Belt and Road" countries. In this study, by using entropy weighting method and multi-index comprehensive evaluation method, 24 specific indicators are selected from three different dimensions: ecology, economy, and society, to construct a comprehensive evaluation index system about "the Belt and Road" countries resilience, and to evaluate the comprehensive resilience and spatial heterogeneity characteristics of China and 64 countries along "the Belt and Road", and use multiple linear regression analysis to identify the main influencing factors of comprehensive resilience and analyze its influencing mechanism. According to the research, the overall resilience level of "the Belt and Road" countries shows prominent differentiation characteristics of "extreme difference", the countries with low and low recovery status account for the vast majority; and the spatial differentiation characteristics of the levels of ecological resilience, economic resilience, and social resilience of countries along "the Belt and Road" are quite different. In countries with high levels of economic development, their comprehensive resilience is significantly higher than that of countries with low levels of economic development. There is no inevitable connection between a country's economic growth rate and its comprehensive resilience level. At the same time, the relationship between resource richness and comprehensive resilience of countries is not apparent, but for those countries that are over-dependent on resources, the
