Dynamically transforming mission contexts in conjunction with ever-increasing budgetary constraints provides great impetus for the Department of Defense (DoD) to identify resilient systems early in the design process. The engineered resilient systems (ERS) community of interest (COI) research efforts focus on identifying and quantifying methods to perform systems engineering analysis in a model-based physics-driven environment. Research conducted has approached resiliency from various perspectives, including inherent resilience, mission and platform resilience, and value-driven resilient tradespace. This article examines resilience in an ERS context and presents multiple perspectives of resilience for consideration when developing modeling and simulation platforms to support analysis of systems under acquisition consideration.

Full textAbstract:
This paper surveys the literature on resilience, provides several definitions of resilience, and proposes a new comprehensive definition for a resilient engineered system, which is: a system that is able to successfully complete its planned mission(s) in the face of disruption(s) (environmental or adversarial), and has capabilities allowing it to successfully complete future missions with evolving threats. This definition captures the subtle differences between resilience and a resilient engineered system. We further examine the terminology associated with resilience to understand the various resilient time-frames and use the terminology to propose a resilience cycle, which differentiates mission resilience (short term) and platform resilience (long term). We then provide insight into various resilience evaluation methodologies and discuss how understanding the full scope of resilience enable designers to better incorporate resilience into system design, decision makers to consider resilient trade-offs in their assessment, and operators to better manage their systems. A resilient engineered system can lead to improved performance, reduced life-cycle costs, increased value, and extended service life for engineered systems.

Full textAbstract:
To provide a building design that is robust, adaptable, and affordable, one must understand the aspects of the building’s geographic location that will impact equipment selections, operating hours, and maintenance needs. One must also consider the building’s “thermal resilience,” i.e., its ability to withstand a heating plant outage. Designing for resilience is of growing importance, especially for military and government installations that must maintain critical functions even during outages. Buildings with a fast rate of temperature degradation with the loss of heating system function have low resiliency; buildings with a slower rate of temperature degradation have higher resiliency. In extreme cold climates, resiliency can play an integral role in protecting property during an outage. A drop in indoor temperature can pose a risk of freezing plumbing, which can lead to burst pipes and interior flooding that can cause enormous and costly damage, and which can effect a loss of workspace in an office building. More resilient designs must consider not only building HVAC installations, but also building envelope and the whole energy infrastructure, including thermal capacity of concrete and brick walls, internal water pipes, critical system redundancy, outside insulation without weak points, and a centrally controlled, low carbon hot water heat supply. This paper describes a quantitative approach to evaluate a system’s resiliency based on analytical and experimental studies conducted under IEA EBC Annex 73 and the Environmental Security Technology Certification Program (ESTCP) project Technologies Integration to Achieve Resilient, Low-Energy Military Installations, to evaluate building energy performance in extreme climate conditions. This work recommends that more thermally resilient designs for buildings in cold climates include consideration of increased thermal resistance of the building envelope, improved whole-building airtightness, and higher thermal mass.

Full textAbstract:
Research suggests that trait resilience may be best understood within an ecological resilient systems theory, comprising engineering, ecological, and adaptive capacity resilience. However, there is no evidence as to how this theory translates to specific life domains. Data from two samples (the United States, n = 1,278; the United Kingdom, n = 211) facilitated five studies that introduce the Domain-Specific Resilient Systems Scales for assessing ecological resilient systems theory within work, health, marriage, friendships, and education. The Domain-Specific Resilient Systems Scales are found to predict unique variance in job satisfaction, lower job burnout, quality-of-life following illness, marriage commitment, and educational engagement, while controlling for factors including sex, age, personality, cognitive ability, and trait resilience. The findings also suggest a distinction between the three resilience dimensions in terms of the types of systems to which they contribute. Engineering resilience may contribute most to life domains where an established system needs to be maintained, for example, one’s health. Ecological resilience may contribute most to life domains where the system needs sustainability in terms of present and future goal orientation, for example, one’s work. Adaptive Capacity may contribute most to life domains where the system needs to be retained, preventing it from reaching a crisis state, for example, work burnout.

AbstractResilient systems have the capability to survive and recover from seriously affecting events. Resilience engineering already is established for socio-economic organisations and extended network-like structures e. g. supply systems like power grids. Transferring the known principles and concepts used in these disciplines enables engineering resilient load-carrying systems and subsystems, too. Unexpected load conditions or component damages are summarised as disruptions caused by nesciense that may cause damages to the system or even system breakdowns. Disruptions caused by nescience can be controlled by analysing the resilience characteristics and synthesising resilient load-carrying systems. This paper contributes to a development methodology for resilient load-carrying systems by presenting a resilience applications model to support engineers analysing system resilience characteristics and behaviour. Further a concept of a systematically structured solution catalogue is provided that can be used for the classification of measures to realise resilience functions depending on system adaptivity and disruption progress. The resilience characteristics are illustrated by 3 examples.

Full textAbstract:
Advanced driver assistance and automated driving systems must operate in complex environments and make safety-critical decisions. Resilient behavior of these systems in their targeted operation design domain is essential. In this paper, we describe developments in our Model-Based Systems Engineering (MBSE) approach to develop resilient safety-critical automated systems. An MBSE approach provides the ability to provide guarantees about system behavior and potentially reduces dependence on in-vehicle testing through the use of rigorous models and extensive simulation. We are applying MBSE methods to two key aspects of developing resilient systems: (1) ensuring resilient behavior through the use of Resilience Contracts for system decision making; and (2) applying simulation-based testing methods to verify the system handles all known scenarios and to validate the system against potential unknown scenarios. Resilience Contracts make use of contract-based design methods and Partially Observable Markov Decision Processes (POMDP), which allow the system to model potential uncertainty in the sensed environment and thus make more resilient decisions. The simulation-based testing methodology provides a structured approach to evaluate the operation of the target system in a wide variety of operating conditions and thus confirm that the expected resilient behavior has indeed been achieved. This paper provides details on the development of a utility function to support Resilience Contracts and outlines the specific test methods used to evaluate known and unknown operating scenarios.

Full textAbstract:
Digital technologies nowadays provide essential support for companies, making them a priority for businesses and a prominent area of study for researchers. In response to the increasing emphasis on sustainability and resilience, new information systems are developing to meet evolving business needs, namely circular and resilient information systems (CRISs). These systems integrate with traditional ones to optimise key performance indicators (KPIs) related to circularity and resiliency. Despite extensive methodologies for evaluating traditional information systems, systems designed for circularity and resiliency need to be assessed in parallel and in depth. Existing evaluations focus on efficiency and user satisfaction but often neglect the unique demands of circularity and resiliency. This study introduces a novel evaluation methodology for CRISs. Through a case study of an innovative system and the established literature, we address real-life needs and challenges in manufacturing. In particular, the system serves the needs of three distinct case studies: Carbon Fibre-Reinforced Polymer (CFRP) waste utilisation in drone manufacturing, recovery of magnets from Waste Electrical and Electronic Equipment (WEEE), and the repurposing of citrus processing waste into juice by-products. Our methodology is built on the 5W1H method to make our approach context-specific and aligned with each case’s unique requirements, making it also replicable for other industries. Our findings offer insights and a tool for practitioners and researchers to evaluate CRIS performance. The research highlights the importance of a two-fold evaluation approach for CRISs, evaluating both pilot-specific KPIs and the system’s technical performance. Policy implications suggest the need for regulatory frameworks and incentives to support the adoption, as well as evaluation, of CRISs and promote sustainable and resilient industrial practices.

Full textAbstract:
Internet-of-Things (IoT) ecosystems tend to grow both in scale and complexity, as they consist of a variety of heterogeneous devices that span over multiple architectural IoT layers (e.g., cloud, edge, sensors). Further, IoT systems increasingly demand the resilient operability of services, as they become part of critical infrastructures. This leads to a broad variety of research works that aim to increase the resilience of these systems. In this article, we create a systematization of knowledge about existing scientific efforts of making IoT systems resilient. In particular, we first discuss the taxonomy and classification of resilience and resilience mechanisms and subsequently survey state-of-the-art resilience mechanisms that have been proposed by research work and are applicable to IoT. As part of the survey, we also discuss questions that focus on the practical aspects of resilience, e.g., which constraints resilience mechanisms impose on developers when designing resilient systems by incorporating a specific mechanism into IoT systems.

Abstract. Infrastructure systems are inextricably tied to society by providing a variety of vital services. These systems play a fundamental role in reducing the vulnerability of communities and increasing their resilience to natural and human-induced hazards. While various definitions of resilience for infrastructure systems exist, analyzing the resilience of these systems within cross-sectoral and interdisciplinary perspectives remains limited and fragmented in research and practice. With the aim to assist researchers and practitioners in advancing understanding of resilience in designing infrastructure systems, this systematic literature review synthesizes and complements existing knowledge on designing resilient vital infrastructures by identifying (1) key conceptual tensions and challenges, (2) engineering and non-engineering measures, and (3) directions for future research. Here, a conceptual framework is developed in which infrastructures are defined as a conglomeration of interdependent social–ecological–technical systems. In addition, we define resilient infrastructures as systems with ability to (i) anticipate and absorb disturbances, (ii) adapt/transform in response to changes, (iii) recover, and (iv) learn from prior unforeseen events. Our results indicate that conceptual and practical challenges in designing resilient infrastructures continue to exist. Hence these systems are still being built without taking resilience explicitly into account. Our review of measures and recent applications shows that the available measures have not been widely applied in designing resilient infrastructure systems. Key concerns to address are identified as (i) the integration of social, ecological, and technical resilience of infrastructure systems with explicit attention paid to cascading effects and dependencies across these complex systems and (ii) the development of new technologies to identify factors that create different recovery characteristics.

Big cities in developing countries face many obstacles related to the built environment when confronted by socioeconomic inequalities, which is reflected by the uneven access to basic living infrastructure, such as sanitation and housing. In the light of new approaches to traditional materials and building techniques, this article aims to investigate the use of digital fabrication tools in the production of lightweight precast systems for the social production of habitat in Brazil.
 To develop a clear assessment of the possibilities created by these technological alternatives, two academic applied researches are considered as case studies: a modular sidewalk for rain water drainage and a precast building system for housing. The main goal here is to discuss the role of high-tech solutions —such as digital fabrication tools and lightweight precast systems— in promoting urban community-driven upgrading initiatives in precarious settlements, accompanied by local economic development.

Health system resilience is a prerequisite for effectively managing cataclysmic events adversely affecting health outcomes. The COVID-19 pandemic reasserted the importance of having resilient health systems and called for a relook at the existing framework that measures health system resilience. Mixed methods were used in this study. The review started with the measurement of health systems resilience and its context. Ebola epidemic triggered the importance, hence our search focused on published literature from 2014 to 2021. Based on the review, a semi-structured tool was developed for key in-depth interviews of seven experts from different countries. The frameworks focused on climate change, disaster management, health systems, city-specific resilience, and e-resilience were reviewed. In-depth interviews highlighted that resilient health systems need to engage the private sector, priority areas like leadership and governance, health resources, and a unified agenda for global collaboration. From experts’ point of view, the inherent nature of health systems to respond to shock was clearly defined as the resilient health system. Health systems resilience definition needs to be defined, based on which assessment indicators will be identified. Indicators need to evolve continuously and be able to measure resilience at sub-national, national, regional, and global levels.

Unternehmensresilienz gewinnt angesichts globaler Unsicherheiten zunehmend an Bedeutung. Um auf externe Veränderungen und Krisen schnell reagieren zu können, müssen Unternehmen ihre Prozesse und Strukturen flexibel anpassen – und damit auch die IT-Systeme, auf die sie angewiesen sind, wie etwa Enterprise-Resource-Planning und Manufacturing-Execution-Systems. Die steigende Abhängigkeit der Unternehmen von diesen IT-Systemen macht ihre Anpassungsfähigkeit umso wichtiger. Viele IT-Systeme bieten zwar eine gewisse technische Flexibilität, notwendige Veränderungen werden jedoch häufig durch organisatorische und menschliche Faktoren erschwert. In diesem Beitrag werden die relevanten Elemente des soziotechnischen Systems im Kontext von IT-Systemen – des soziotechnischen Informationssystems – identifiziert und definiert. Das daraus entwickelte Modell unterstützt Unternehmen dabei, die Komplexität von IT-Systemen zu durchdringen und resilienzfördernde Anpassungen effektiv umzusetzen. Es legt die Grundlage für die Identifikation von Wechselwirkungen zwischen den Elementen, um Stellschrauben für resiliente IT-Systeme zu erkennen und zu nutzen.

Motivation: The efficient functioning of transportation systems is subject to various types of disruptions and risks. Transportation systems are strongly affected by all kinds of local, regional, national, or global crises. The European Union’s transport policy indicates the need to build sustainable, intelligent, and resilient urban mobility systems based on public mass transit. The paradigm of resilience has gained particular importance in the context of the global crises of the last five years. Resilient urban mobility systems are intended to provide the ability to respond quickly to disruptions that occur, allowing urban organisms to achieve operational stability.Aim: The purpose of the study is to identify the main problems with financing the resilience of public mass transit systems in Polish cities. The specific aims are the identification of the factors determining the resilience of urban mobility systems and tools supporting it, measures of resilience and ways of financing it. The study sought to verify whether the mobility systems of Polish regional cities can be considered resilient from a financial point of view.Results: Financing urban public mass transport in Poland is based on two key sources of income: fees from ticket sales and payments (compensations) made by local governments. The economic and energy crisis contributed to a significant increase in the operating costs of public mass transportation providers. In this context, the key to building resilient public mass transport systems in urban areas is to make changes to existing models to ensure a stable PTA financing system.

The rapid development of information technology has expanded the capabilities of cyberthreads regarding computer systems. Cybercriminals are developing new ways to avoid attack detection, so existing approaches are not able to withstand the growing threat of attacks. Meanwhile, the consequences of cyberattacks are becoming more dangerous and destructive. One of the approaches to solve the problem is the construction of resilient systems that are able to quickly recover and continue to function under attack conditions. The subject of research is the construction process of the resilient computer systems in the face of cyber threats. The goal is to develop a taxonomy and ontology of resilient computer systems under cyberthreats. Results. The article presents the definitions of the resilience from the point of view of cybersecurity, presents the gap between the concepts of resilience and dependability. The paper presents the main elements of the taxonomic scheme of computer system resilience, which include threats (changes in the environment and requirements, network attacks, attacks on software, software and hardware vulnerabilities, errors, failures), information and technical conditions that computer system passes during its operating cycle, the principles on which resilience is based (proactivity, adaptability, resistance, diversity, elasticity, controlled degradation, defense in depth, ability to evolvability), as well as primary and secondary properties. Based on the above elements, a generalized taxonomic scheme of resilience related to information security has been developed. The work presents the operational cycle of a resilient CS as a set of information and technical states that the system goes through (preparation, system protection, threat detection, threat absorption, response to a threat, system recovery after a cyberattack, adaptation.) An ontology scheme of the resilience from the point of view of information security of computer systems in the presence of cyberthreats is developed. Conclusions A taxonomy and ontology of resilient computer systems in the presence of cyberthreats has been developed.

Full textAbstract:
Resilience thinking provides valuable insights into the dynamics of complex adaptive systems. To achieve resilience in urban systems, it can be fruitful to delve into the intricacies of resilience processes. This paper theorizes about how the specific characteristics of resilient systems can be integrated into the spatial design of cities. Emphasizing the importance of the built form and spatial systems in maintaining order within urban processes, we focus on how adaptive renewal cycles can be applied to various systems and dimensions where urban change, adaptation, and renewal occur. The paper identifies key resilient system characteristics applicable to urban spatial form and contextualizes urban renewal within the adaptive renewal cycle—a framework originally developed to capture temporal and spatial ecosystem dynamics. We integrate insights within ‘space syntax theory’, theorizing about how cities renew themselves over space and time. We discuss instances of ‘compressed resilience’ and the challenges posed by the ‘tyranny of small decisions’ in urban planning and development. In conclusion, we identify future research directions in the theory of spatial morphology and resilient urban systems, emphasizing the need for a deeper understanding of the interplay between urban processes, urban form, resilience, and adaptive renewal.

This study focuses on the development of a conceptual framework that delineates the resilience of information systems through the analysis of their key operational stages in the context of countering prevalent threats. These stages encompass preliminary security measures, active counteraction against threats, as well as strategies for adaptation and recovery following security breaches. The realization of this objective necessitates the identification and formulation of fundamental goals and objectives associated with resilience, which play a crucial role in the neutralization of potential threats and significantly influence risk management policies, emphasizing the importance of a comprehensive analysis of the key functions of organizations. Throughout the research, special attention was devoted to the creation of models for resilient and non-resilient behavioral scenarios of systems and their responses to threats. The employment of the delta function facilitated a detailed examination of the stages of resilient response to threats, including the processes of adaptation and subsequent recovery. The work contributes significantly to the field of information security, presenting a multifaceted approach to advancing the resilience of information systems.

The paper contains the results of the development and implementation of a cybernetic approach to the creation of resilient systems. The architecture of a resilient system contains redundant components compared to a traditional feedback control system. This is primarily due to the need to implement additional channels in the control system to respond to changes in requirements, environment, or unspecified faults and failures. The general structure of a resilient system is based on the principle of dividing control channels for functional and non-functional characteristics. This allows to react to changes in the information component of the environment during attacks on the system to ensure its cybersecurity. The case for a space resilient system with online verification is described. Three scenarios of the system behaviour to assure resilience are suggested and the first scenario is explored by the use of Markov model. That allows offering options for improving availability function and other indicators of resilient systems

Extreme weather events lead to electrical network failures, damages, and long-lasting blackouts. Therefore, enhancement of the resiliency of electrical systems during emergency situations is essential. By using the concept of standby redundancy, this paper proposes two different energy systems for increasing load resiliency during a random blackout. The main contribution of this paper is the techno-economic and environmental comparison of two different resilient energy systems. The first energy system utilizes a typical traditional generator (TG) as a standby component for providing electricity during the blackouts and the second energy system is a grid-connected microgrid consisting of photovoltaic (PV) and battery energy storage (BES) as a standby component. Sensitivity analyses are conducted to investigate the survivability of both energy systems during the blackouts. The objective function minimizes total net present cost (NPC) and cost of energy (COE) by considering the defined constraints of the system for increasing the resiliency. Simulations are performed by HOMER, and results show that for having almost the same resilience enhancement in both systems, the second system, which is a grid-connected microgrid, indicates lower NPC and COE compared to the first system. More comparison details are shown in this paper to highlight the effectiveness and weakness of each resilient energy system.

AbstractThe 2014–15 Ebola epidemic in West Africa highlighted the significance of trust between the public and public health authorities in the mitigation of health crises. Since the end of the epidemic, there has been a focus amongst scholars and practitioners on building resilient health systems, which many see as an important precondition for successfully combatting future outbreaks. While trust has been acknowledged as a relevant component of health system resilience, we argue for a more sustained theoretical engagement with underlying models of trust in the literature. This article takes a first step in showing the importance of theoretical engagement by focusing on the appeal to rational models of trust in particular in the health system resilience literature, and how currently unconsidered assumptions in this model cast doubt on the effectiveness of strategies to generate trust, and therein resilience, during acute public health emergencies.

The study confirms the relationship between fiscal resilience and socio-economic resilience of the regions. The analysis of panel data for 75 regions from 2007 to 2016 shows that there are significant differences in the dynamics of indicators in different periods. In particular, the degree of exposure to the negative effects of the crises of 2008—2009 and 2014—2015 in non-resilient regions is higher than in resilient ones.

Objectives. To develop and test a framework to assess the potential of public health systems to maintain a resilient performance. Methods. Quantitative data from public databases and qualitative data from technical reports of Brazilian health authorities were used to develop the framework which was assessed and modified by experts. Fuzzy logic was used for the mathematical model to determine scores for four resilient abilities – monitoring, anticipation, learning, and response – and an aggregated coefficient of resilient potential in health care. The coefficient measures used data from before the coronavirus disease 2019 (COVID-19) pandemic. These were compared with measures of the actual performance of health systems in 10 cities in Brazil during the pandemic. Results. The coefficient of resilient potential in health care showed that the cities most affected by COVID-19 had lower potential for resilient performance before the pandemic. Some local health systems had adequate response capabilities, but other abilities were not well developed, which adversely affected the management of the spread of COVID-19. Conclusions. The coefficient of resilient potential in health care is useful to indicate important areas for resilient performance and the different types of resilience capacities that can be considered in different contexts and levels of public health systems. Regular assessment of the potential of health systems for resilient performance would help highlight opportunities for continuous improvement in health system functions during chronic stress situations, which could strengthen their ability to keep functioning in the face of sudden disturbances.

Full textAbstract:
In a world facing unprecedented challenges, such as climate changes and growing social problems, the pharmaceutical industry must ensure that its supply chains are environmentally sustainable and resilient, guaranteeing access to key medications even when faced with unanticipated disruptions or crises. The core goal of this work is to develop an innovative simulation-based approach to support more informed and effective decision making, while establishing reasonable trade-offs between supply chain robustness and resiliency, operational efficiency, and environmental and social concerns. Such a decision-support system will contribute to the development of more resilient and sustainable pharmaceutical supply chains, which are, in general, critical for maintaining access to essential medicines, especially during times of crises or relevant disruptions. The system will help companies to better manage and design their supply chains, providing a valuable tool to achieve higher levels of resilience and sustainability. The study we conducted has two primary contributions that are noteworthy. Firstly, we present a new advanced approach that integrates multiple simulation techniques, allowing for the modeling of highly complex environments. Secondly, we introduce a new conceptual framework that helps to comprehend the interplay between resiliency and sustainability in decision-making processes. These two contributions provide valuable insights into understanding complex systems and can aid in designing more resilient and sustainable systems.

Full textAbstract:
The complete failure of the power systems infrastructure in Puerto Rico, following Hurricanes Irma and Maria in 2017, severely hampered the recovery efforts of multiple critical infrastructure systems (CIS). Understanding the relationships of infrastructure recovery efforts between power infrastructure systems and the other CIS has the potential to be a key in developing an effective recovery plan leading to resilient infrastructure systems, and thereby a more resilient community. This paper explores the critical interfaces and interdependencies in CIS recovery by examining the disruptions and recovery progress of the CIS, including the power infrastructure systems, in Puerto immediately following the events of Hurricane Maria. This research uncovers that strong CIS recovery interdependency relationships exist between the power infrastructure systems and other CIS in Puerto Rico, and these relationships contribute to the resilience of these CIS. The resultant CIS recovery associations may potentially predict the recovery progress of post-disaster CIS recovery centered on the power infrastructure systems and lay the groundwork for further interdependency analysis of CIS in post-disaster scenarios. The results may also be helpful while designing CIS for resiliency in natural disaster areas.

AbstractIn Information Systems development, resilience has often been treated as a non-functional requirement and little or no work is aimed at building resilience in end-users through systems development. The question of how values and resilience (for the end-user) can be incorporated into the design of systems is an on-going research activity in user-centered design. In this paper we evaluate the relation of values and resilience within the context of an ongoing software development project and contribute a formal model of co-design based on a significant extension of Abstract Design Theory. The formal analysis provides a full and clear-cut definition of the co-design space, its objectives and processes. On the basis of both, we provide an abstract definition of resilient system (for the end-user). We conclude that value-sensitive co-design enforces better resilience in end-users.

Abstract: In recent years, with the accelerated process of urbanization, the continuous growth of urban areas and population sizes has posed higher demands on urban earthquake safety. The theory of resilient cities offers a new approach to effectively address urban earthquake safety risks. However, there is still a lack of reasonable methods for assessing and constructing urban seismic resilience both domestically and internationally. Therefore, this paper elucidates the connotation, essential characteristics, components, and evaluation indicators of a seismic-resilient city, summarizing the components of urban seismic resilience as "one fundamental, two guarantees," which include the engineering system, institutional system, and social and economic system. This paper establishes a dual-parameter urban seismic resilience assessment method based on post-earthquake losses and recovery time, proposing a "set goals, assess, improve, reassess" approach for building resilient cities. The proposed method can provide theoretical guidance and practical basis for assessing and enhancing the seismic resilience of individual infrastructures, engineering systems, urban systems, and resilience to other disasters.

As systems continue to grow in scale and complexity and have to operate safely in challenging disruptive environments, system safety and resilience has become a critical requirement. This recognition has drawn attention to the concept of resilience, which has different definitions and several different interpretations that tend to be domain specific. For example, resilience in health care clinics means something quite different than resilience in self-driving cars, or energy grids. This paper reviews the different characterizations of resilience and assesses their value proposition in realizing engineered resilient systems. This paper emphasizes the importance of systems modeling in engineering resilient systems and presents an overarching methodology that employs different modeling approaches for operational tasks as a function of problem context. This paper specifically focuses on systems modeling in partially observable and potentially hostile environments. It discusses the need for system model verification, which is key to safety, and system flexibility and adaptability, which are key to resilience. It introduces a formal, probabilistic modeling construct called the “resilience contract.” This construct employs a state-based representation that formalizes the concept of resilience while enabling system model verification and affording requisite flexibility for adaptation and learning. The key findings of our research are that different system modeling approaches and algorithms are needed based on mission tasks and operational context; adaptive capacity and continual adaptability are the two promising characterizations of resilience that can be cost-effectively realized in real-world systems; and the resilience contract construct is an effective means for probabilistic verification of system model correctness while affording flexibility needed for adaptation and learning. Collectively, these findings contribute to the body of knowledge in both model-based systems engineering (MBSE) and engineered resilient systems.

The social structure of India is rapidly evolving, towards modernization. The urban population of India is projected to approach 60 crores by 2036. Urban health resilience stands for building the capacity of urban systems to withstand and adapt to health-related stresses like natural disasters, man-made disasters, and pandemics like COVID-19 and the capability to recover from them by well-equipped hospitals, efficient emergency response mechanisms, and a network of well-trained and motivated healthcare professionals. Also, the involvement of communities is central to building urban health resilience. Strong policy frameworks are required for establishing a resilient urban health ecosystem. Addressing social determinants, such as income inequality, education, and housing, is also a basis of building urban health resilience. Some examples have been instrumental in designing a resilient urban health system like Singapore’s Smart Nation Initiative, Copenhagen, Denmark’s Model for Sustainable Urban Living internationally, Ahmedabad’s Heat Action Plan and Kochi’s Waterfront Development for Climate Resilience are excellent examples from our country. The suggested strategy for an urban resilient system is a Rapid, Extensive, Sturdy, Ingenious, Lucid approach with an International collaboration for an Enthusiastic, Non-latent, Continuous Early warning system (RESILIENCE).

Full textAbstract:
Purpose: This study explores the organisational barriers to implementing resilient safety management systems (RSMS) in the Ghanaian construction industry. Study Design/Methodology/Approach: A quantitative research approach involving a structured questionnaire survey was utilised. The survey included 144 members of the Ghana Association of Building and Civil Engineering Contractors. A purposive sampling method was used. The analysis employed was exploratory factor analysis. Findings: The research identified significant barriers to implementing resilient safety management systems, including inadequate training and awareness, fragmented communication, and financial constraints. These barriers contribute to the Ghanaian construction industry's reactive rather than proactive safety culture. Research Limitations: The study's geographic restrictions to Ghana could make its conclusions less applicable to other areas. Furthermore, depending solely on self-reported data can introduce response bias. Practical Implication: The findings suggest that addressing these barriers requires targeted interventions, such as enhanced training programs, improved communication channels, and financial support for safety initiatives. These measures can help construction firms in Ghana build a more resilient safety culture. Social Implication: Enhancing the resilience of safety management systems can reduce workplace accidents and injuries, improving construction workers' overall health and safety. This aligns with broader societal goals of promoting safe and sustainable working environments. Originality/Value: This study provides new insights into the specific organisational barriers to RSMS in the Ghanaian construction sector. It contributes to the limited literature on resilience in construction safety management in developing countries and offers practical recommendations for overcoming these barriers.

The energy availability at all occupied times of the buildings poses a challenge in most developing countries. However, it is readily available to the different sectors in the advanced world. This robust and resilient energy supply system needs to be investigated. In this research, resilience in energy supply of the UK, USA & Europe is explored and how they have achieved this. Further, the resilience in the energy supply of Pakistan is discussed to highlight its shortcomings, and some solutions are proposed, based on the in-depth analysis of past, present and future supply chains-highlights on circular debt. The 4 A’s of broader resilience sense, encapsulating availability, accessibility, acceptability and affordability, are explained. The threats and challenges of this system are overcome by providing a conceptual transition model against the conventional supply streams. The energy supply and demand, along with plans to achieve sustainability, are also studied. The vulnerable energy system exhibits the presence of real and running faults, which can be a warning for the proper performance of the system. Energy supply must ensure two factors, referring to accessibility, dependability, and economic stability. The research has produced an ‘Orbital Model’ of energy resilience for Pakistan. The resilient path should be decreasing reliance on foreign energy, a variety of supply, enhanced efficiencies, appropriate back-ups, renewable heat initiatives (RHI) tactics, good management, decarbonization, localised production and green energy exploitation, are few measures which can bring Pakistan close to have a low carbon resilient energy supply system.

Full textAbstract:
Most eHealth systems are cyber-physical systems (CPSs) making safety-critical decisions based on information from other systems not known during development. In this design science research, a conceptual resilience governance framework for eHealth CPSs is built utilizing 1) cybersecurity initiatives, standards and frameworks, 2) science of design for software-intensive systems and 3) empowering cyber trust and resilience. According to our study, a resilient CPS consists of two sub-systems: the proper resilient system and the situational awareness system. In a system of CPSs, three networks are composed: platform, software and social network. The resilient platform network is the basis on which information sharing between stakeholders could be created via software layers. However, the trust inside social networks quantifies the pieces of information that will be shared - and with whom. From citizens’ point of view, eHealth is wholeness in which requirements of information security hold true. Present procedures emphasize confidentiality at the expense of integrity and availability, and regulations/instructions are used as an excuse not to change even vital information. The mental-picture of cybersecurity should turn from “threat, crime, attack” to “trust” and “resilience”. Creating confidence in safe digital future is truly needed in the integration of the digital and physical world’s leading to a new digital revolution. The precondition for the exchange of information “trust” must be systematically built at every CPS’ level. In health sector, increasingly interconnected social, technical and economic networks create large complex CPSs, and risk assessment of many individual components becomes cost and time prohibitive. When no-one can control all aspects of CPSs, protection-based risk management is not enough to help prepare for and prevent consequences of foreseeable events, but resilience must be built into systems to help them quickly recover and adapt when adverse events do occur.

Although the severity of the COVID-19 pandemic has appears to have subsided in most parts of the world, nevertheless, in addition to six million deaths, it has yielded unprecedented challenges in the economy, energy, education, urban services, and healthcare sectors. Meanwhile, based on some reports, smart solutions and technologies have had significant success in achieving pandemic-resilient cities. This paper reviews smart city initiatives and contributions to the prevention and treatment of coronavirus disease, as well as reducing its destructive impact, leading towards pandemic-resilient economic and health systems. Furthermore, the situational awareness contributions are reviewed in pandemic-resilient governance. The main contribution of this study is to describe the construction of social capital in smart cities as a facilitator in creating a pandemic-resilient society in crisis through two analyses. Moreover, this research describes smart cities’ energy as interconnection of energy hubs (EHs) that leads to a high level of resiliency in dealing with the main challenges of the electricity industry during the pandemic. Energy-hub-based smart cities can contribute to designing pandemic-resilient energy infrastructure, which can significantly affect resilience in economic and health infrastructure. In brief, this paper describes a smart city as a pandemic-resilient city in the economic, energy, and health infrastructural, social, and governmental areas.
