Infrastructure networks such as power, communication, gas, water, and transportation rely on one another for their proper functioning. Such infrastructure networks are subject to diverse disruptive events, including random failures, malevolent attacks, and natural disasters, which could significantly affect their performance and adversely impact economic productivity. Moreover, the proliferation of interdependencies among infrastructure networks has increased the complexity associated with recovery planning after a disruptive event. Consequently, providing solution approaches to restore interdependent networks following the occurrence of a disruptive event has attracted many researchers in the last decade. The goal of this paper is to help decision makers plan for recovery following the occurrence of a disruptive event, to procure strategies that center not only on recovering the system promptly, but also such that the weighted average performance of the system is maximized during the recovery process (i.e., enhancing its resilience). Accordingly, this paper studies the interdependent network restoration problem (INRP) and proposes a resilience-driven multi-objective optimization model to solve it. The proposed model aims to: (i) prioritize the restoration of the disrupted components for each infrastructure network, and (ii) assign and schedule the prioritized networks components to the available work crews, such that the resilience of the system of interdependent infrastructure networks is enhanced considering the physical interdependency among them. The proposed model is formulated using mixed-integer programming (MIP) with the objectives of: (i) enhancing the resilience of the system of interdependent infrastructure networks, and (ii) minimizing the total costs associated with the restoration process (i.e., flow, restoration, and disruption costs).

Abstract
Infrastructure networks such as power, communication, gas, water, and transportation rely
on one another for their proper functioning. Such infrastructure networks are subject to
diverse disruptive events, including random failures, malevolent attacks, and natural disas-
ters, which could significantly affect their performance and adversely impact economic
productivity. Moreover, the proliferation of interdependencies among infrastructure net-
works has increased the complexity associated with recovery planning after a disruptive
event. Consequently, providing solution approaches to restore interdependent networks
following the occurrence of a disruptive event has attracted many researchers in the last
decade. The goal of this paper is to help decision makers plan for recovery following the
occurrence of a disruptive event, to procure strategies that center not only on recovering the
system promptly, but also such that the weighted average performance of the system is
maximized during the recovery process (i.e., enhancing its resilience). Accordingly, this
paper studies the interdependent network restoration problem (INRP) and proposes a
resilience-driven multi-objective optimization model to solve it. The proposed model aims
to: (i) prioritize the restoration of the disrupted components for each infrastructure network,
and (ii) assign and schedule the prioritized networks components to the available work
crews, such that the resilience of the system of interdependent infrastructure networks is
enhanced considering the physical interdependency among them. The proposed model is
formulated using mixed-integer programming (MIP) with the objectives of: (i) enhancing
the resilience of the system of interdependent infrastructure networks, and (ii) minimizing
the total costs associated with the restoration process (i.e., flow, restoration, and disruption
costs). Moreover, the proposed model considers partial disruptions and recovery of the
disrupted network components, and partial dependence between nodes in different net-
works. The proposed model is illustrated through a system of interdependent infrastructure
networks after multiple hypothetical earthquakes in Shelby County, TN, United States.

... Resilience, originally conceptualized by Holling in 1973 [12], denotes the inherent capacity of a system or system-of-systems to absorb perturbations, adaptively reconfigure, and reestablish critical functionalities [4,[13][14][15]. Over the past decade, substantial progress has been achieved in the theoretical foundations and quantitative assessment of resilience across domains such as electrical power infrastructure [16], transportation systems [17], and defense-oriented system-ofsystems architectures [4]. ...

Resilience of unmanned weapon system-of-systems (UWSoS) is critical for preserving sustained operational capability amidst adversarial disruptions and cascading subsystem degradations. However, prevailing resilience enhancement methodologies frequently overlook the semantic richness embedded within meta-paths spanning the heterogeneous network, thereby constraining their adaptability and robustness. This study introduces meta-path-driven reinforcement learning(MPD-RL), an innovative framework that synergizes meta-path-guided node embedding with deep reinforcement learning to surmount this limitation. Within MPD-RL, a topology-informed embedding mechanism utilizes meta-path-based random walks and structurally derived matrices to encapsulate high-order relational semantics intrinsic to the UWSoS architecture. Furthermore, an auxiliary loss function is introduced to embed meta-path knowledge into the reinforcement learning agent’s optimization process, thereby steering policy development toward resilience-oriented decision making. By incorporating meta-path semantics into both the agent’s perceptual state and objective function, MPD-RL facilitates proactive identification and fortification of critical communication pathways, enabling sustained network performance under adverse conditions. Extensive simulation results substantiate that MPD-RL markedly surpasses contemporary baseline techniques in preserving network connectivity and functional integrity across diverse failure and attack scenarios.
... To address this limitation, scholars utilise mathematical programming to find an optimal resource scheduling sequence. Stochastic programming (Fang & Sansavini, 2019;Kong et al., 2023;Xu, Li, & Chen, 2024) or mixed integer programming (Almoghathawi et al., , 2021Arab et al., 2015;Arjomandi-Nezhad et al., 2020;Aziz et al., 2023;Edib et al., 2023;Karakoc et al., 2019;Lei et al., 2019;Li et al., 2021;Luo & Yang, 2021;Mao et al., 2021;Sadnan et al., 2022;Sang et al., 2021) are usually applied. These approaches are primarily utilised for studying power systems (see Fig. 2(c)). ...
... For example, the research on infrastructure networks, such as transportation and power, can not only guide the optimal allocation of resources but also reveal the possible fatal weaknesses of these systems and give corresponding solutions. 38,39 Research on the transmission network of infectious diseases can help us find super-spreaders faster and implement isolation and control measures to break the transmission chain and slow the spread of the epidemic. However, as the exploration of real-world systems continues, network science researchers have realized that networks alone cannot provide a complete description of complex systems because human interactions in real social networks are often higher-order. ...

Bootstrap percolation is a widely studied model to investigate the robustness of a network for cascading failures. Extensive real-world data analysis has revealed the existence of higher-order interactions among elements, i.e., the interactions beyond pairwise, which are usually described by hypergraphs. In this paper, we propose a generalized bootstrap percolation model on hypergraph, which assumes that the activation of an inactive node depends on the number of active neighbors through its hyperedges. Through numerical simulation and theoretical analysis, we found that the bootstrap percolation threshold and the phase transition type are closely related to the infection threshold and the proportion of higher-order edges. When the infection threshold is significant, for any initial activation probability, the size of the giant active component (GAC) shows continuous growth with increasing occupation probability. When the infection threshold is small, with the increase of the initial activation probability, the size of the GAC changes from continuous growth to discontinuous growth. In addition, we found that in the case of a fixed network average degree, increasing the proportion of higher-order edges will reduce the percolation threshold, which is conducive to enhancing the robustness of the network. At the same time, higher-order edges create more opportunities for inactive nodes to be activated, and increasing the proportion of higher-order edges under the same conditions will change the size of the GAC from continuous growth to discontinuous growth.

The high volume of user-generated content in social networks and online platforms facilitates instant access to a substantial amount of data. However, users’ inability to validate and verify the content of online information exacerbates the spread of false and misleading information. Engagement with disinformation can result in inaccurate judgment and maladaptive decision-making, which becomes especially problematic when disinformation targets physical infrastructures. In this research, we explore the effects of a hypothetical scenario where disinformation is spread claiming that a particular subway station in New York City will be closed for maintenance (similar to rumors circulated in New York City in recent years). Assuming that subway users plan their routes based on efficiency (i.e. the shortest travel time), believing such false information would lead to extended travel times and create an unexpected demand for alternative subway lines. Situations like these raise several questions: (i) How can we devise an efficient mechanism to limit the spread of disinformation in communication in a social network? (ii) How can we interdict the spread of disinformation to combat weaponized disinformation campaigns initiated by adversaries? and (iii) What effect does information protection have on the utilization of infrastructure network components? To answer these questions, we linearized a nonlinear integer programming model for competitive information dissemination and proposed a mixed-integer linear programming model to interdict the spread of disinformation in a social network, taking into account the structure of social interactions to help mitigate adversary effects of uncontrolled disinformation spread. We illustrate the proposed model with a case study of the New York City subway system.

Transportation systems are vulnerable to disruptive events such as natural disasters, industrial accidents, terrorist attacks, and climate change. Vulnerability assessment is necessary to understand the impacts of these disruptive events, identify underlying deficiencies within the network, and improve transportation system resilience. Multi-modal transportation networks are often interdependent and form a “system of systems”, which creates a susceptibility to cascading indirect impacts within the integrated transportation network. Accurately modeling these interdependencies typically requires a large amount of data, such as traffic flow and travel demand information for transportation systems, which may not be available or accessible. This paper proposes a network topology-based framework to conduct an interdependent transportation network vulnerability analysis by introducing an algorithm to simulate cascading failures across transport systems. The proposed framework estimates the vulnerability of the network with respect to a specific hazard, combining the network topology and the functional attributes of the transportation infrastructure components. A case study with real-world data is conducted to demonstrate the applicability of the framework to the Houston freight transportation network, and to understand the network performance under different scenarios. This study presents an alternate method that stakeholders may use to assess interdependent transportation network vulnerability when more detailed flow-based data is not available.

The power system is continuously evolving towards a smarter grid by adding intelligent electrical devices that leverage communication technologies to provide visualisation, control and automation. The integration of power system and communication network has brought challenges into the resilience of interdependent networks. Following an outage or blackout, system operators cannot only restore one network while simply ignoring the interconnection with the other network. Effective restoration strategies that involve co‐ordination between power system and communication network have become critical in enhancing the resilience. An optimisation‐based restoration strategy is developed to coordinate the restoration actions between two networks. The problem is modelled as a mixed integer linear programming problem, with the objective of activating every node in both networks with the minimum number of activation/energisation of branches. The developed strategies are tested on the modified IEEE 14‐bus system incorporating communication network. Simulation results demonstrate that the coordinated restoration strategies are effective and critical in the successful recovery of interdependent networks. The developed model could also provide insights in network design and planning to enhance the resilience of interdependent power system and communication network.

The multi-modal freight transportation network plays an important role in the economic vitality of states, regions, and the broader country. The functionality of this network is threatened by disruptive events that can disable the capacity of the network to enable flows of commodities in portions of nodes and links. This work integrates a multi-commodity network flow formulation with an economic interdependency model to quantify the multi-industry impacts of a disruption in the transportation network to ultimately measure and assess the importance of network components. The framework developed here can be used to measure the efficacy of strategies to reduce network vulnerability from the unique perspective of multi-industry impacts. The framework is illustrated with a case study considering the multi-modal freight transportation network consisting of inland waterways, railways, and interstate highways that connect the state of Oklahoma to surrounding states.

Vulnerability due to inter-connectivity of multiple networks has been observed in many complex networks. Previous works mainly focused on robust network design and on recovery strategies after sporadic or massive failures in the case of complete knowledge of failure location. We focus on cascading failures involving the power grid and its communication network with consequent imprecision in damage assessment. We tackle the problem of mitigating the ongoing cascading failure and providing a recovery strategy. We propose a failure mitigation strategy in two steps: 1) Once a cascading failure is detected, we limit further propagation by redistributing the generator and load's power. 2) We formulate a recovery plan to maximize the total amount of power delivered to the demand loads during the recovery intervention. Our approach to cope with insufficient knowledge of damage locations is based on the use of a new algorithm to determine consistent failure sets (CFS). We show that, given knowledge of the system state before the disruption, the CFS algorithm can find all consistent sets of unknown failures in polynomial time provided that, each connected component of the disrupted graph has at least one line whose failure status is known to the controller.

A system is antifragile if its performance improves as the result of exposure to stressors, shocks, or disruptions. This behavior is typical of complex systems and is not usually exhibited by engineered technical systems. In fact, technical systems can display antifragility when new investments are allocated, e.g., after disasters. This study proposes an optimization model for the postdisaster restoration planning of infrastructure networks, taking into account the possibility of combining the construction of new components and the repair of failed ones. The strategic goal is to determine the optimal target system structure so that the performance of the target system is maximized under the constraints of investment cost and network connectivity. The problem is formulated as mixed-integer binary linear programming (MILP), and an efficient Benders decomposition algorithm is devised to cope with the computational complexity of its solution. The proposed approach is tested on a realistic infrastructure network: the 380-kV power transmission grid of northern Italy. The results show that the restored network can achieve an improved functionality as compared to the original network if new components are constructed and some failed components are not repaired, even when the former is much more expensive than the latter. Therefore, antifragility provides an opportunity for the system to meet future service demand increases and a perspective under which disruptions can be seen as chances for system performance improvements.

Critical infrastructure networks such as transportation, telecommunications, electric power, natural gas and oil, and water distribution rely on one another for their proper functionality. Hence, they are increasingly interdependent, making them highly vulnerable, where the occurrence of even a small disruption in one infrastructure network could propagate to affect other dependent infrastructure networks leading to a more significant adverse impact on society. Therefore, a key aspect of preparedness planning in infrastructure networks is identifying the critical network components that influence not only (i) the performance of their networks the most when disrupted and restored but also (ii) the performance of other networks due to their interdependent nature. This work offers a means to study the importance of interdependent network components with a resilience-focused performance measure in mind. We propose two component importance measures, (i) the first of which quantifies the effect of disrupted components on the resilience of the interdependent infrastructure networks once they are recovered, while (ii) the second measures the potential impact on the resilience of the interdependent infrastructure networks caused by a specific disrupted network element. The proposed measures are illustrated through generated interdependent power-water networks and compared with two other common network centrality measures. The use of such measures could identify components that are candidates for the allocation of resources to reduce their vulnerability or to expedite their recovery.

Critical infrastructure networks such as electric power, water distribution, natural gas, transportation and telecommunications are the backbone of modern societies as they provide them with the services that are essential for their continuous functioning. However, these infrastructure networks are not isolated from each other but instead, most of them rely on one another to be functional. Hence, they are highly vulnerable to any disruptive event (e.g., components deteriorating, terrorist attacks, or natural disasters) which makes their restoration more challenging task for decision makers. In this paper, we study the restoration problem of a system of interdependent infrastructure networks following a disruption event considering different disruptions scenarios. We propose a resilience-driven multi-objective restoration model using mixed-integer programming that aims to maximize the resilience of the system of interdependent infrastructure networks while minimizing the total cost associated with the restoration process. The restoration model considers the availability of limited time and resources and provides a prioritized list of components, nodes or links, to be restored along with assigning and scheduling them to the available work crews. The proposed model is illustrated through a generated system of interdependent power-water networks, however it is applicable to any physically interdependent networks.

Modern communities heavily depend on critical infrastructure networks, such as power, water, gas, telecommunications, and transportation. These infrastructure networks are often dependent upon each other for operation. The interdependence of infrastructure networks makes them more vulnerable to disruptive events, such as malevolent attacks, natural disasters, and random failures. Since daily life requires the effective operation of these networks, it is important that they are able to withstand or recover quickly from a disruption. To return the networks to some desired level of performance, work crews must be scheduled to restore certain disrupted components (nodes or links). The proposed model is a multiobjective mixed-integer programming formulation that integrates 1) the order of link and node recovery, 2) the scheduling of recovery tasks to work crews, and 3) the location of facilities (or resources), where each work crew should originate from to effectively facilitate the recovery process. This study demonstrates the use of the model through an illustrative example of two interdependent infrastructure networks that exhibit behaviors of electric power and water networks. Considering four disruption scenarios, the example illustrates how recovery may change by varying the number of facilities established for work crews in each network.

Enhancing the resilience of infrastructure systems is critical to the sustainability of the society against multiple disruptive events. This paper develops an approach for allocating restoration resources to enhance resilience of interdependent infrastructure systems. According to Inoperability Input-Output Model, a resilience metric for infrastructure systems is developed, in which the performance loss of infrastructure systems resulting from a disruptive event is measured in economic loss and inoperability. Model for determining the optimal infrastructure restoration resources allocation is proposed with the objective of maximizing resilience. Infrastructure interdependence is modeled by the Dynamic Inoperability Input-Output Model (DIIM), which is an accepted economic model for describing the interconnected relationship of industry sectors. To investigate the utility of the restoration resource allocation model, numerical analysis is conducted with an example derived from the data provided by the US Bureau of Economic Analysis. The results show that: (1) the optimal restoration resource allocation varies with the resource budget; (2) for a specific disruptive event, there exists an optimal resource budget which can minimize the sum of restoration cost and the performance loss of infrastructure system; and (3) the significance of factors such as initial inoperability of infrastructure systems on the optimal allocation. The proposed model can assist the decision makers in (i) better understand the effects of resource allocation, and (ii) deciding which allocation strategies should be used following a disruptive event.

Theory, methodology, and applications of risk analysis contribute to the quantification and management of resilience. For risk analysis, numerous complementary frameworks, guidelines, case studies, etc., are available in the literature. For resilience, the documented applications are sparse relative to numerous untested definitions and concepts. This essay on resilience analytics motivates the methodology, tools, and processes that will achieve resilience of real systems. The paper describes how risk analysts will lead in the modeling, quantification, and management of resilience for a variety of systems subject to future conditions, including technologies, economics, environment, health, developing regions, regulations, etc. The paper identifies key gaps where methods innovations are needed, presenting resilience of interdependent infrastructure networks as an example. Descriptive, predictive, and prescriptive analytics are differentiated. A key outcome will be the recognition, adoption, and advancement of resilience analytics by scholars and practitioners of risk analysis.

Network repair strategies are tactical methods that restore the efficiency of damaged networks; however, unreasonable repair strategies not only waste resources, they are also ineffective for network recovery. Most extant research on network repair focuses on static networks, but results and findings on static networks cannot be applied to evolutionary dynamic networks because, in dynamic models, complex network repair has completely different characteristics. For instance, repaired nodes face more severe challenges, and require strategic repair methods in order to have a significant effect. In this study, we propose the Shell Repair Strategy (SRS) to minimize the risk of secondary node failures due to the cascading effect. Our proposed method includes the identification of a set of vital nodes that have a significant impact on network repair and defense. Our identification of these vital nodes reduces the number of switching nodes that face the risk of secondary failures during the dynamic repair process. This is positively correlated with the size of the average degree and enhances network invulnerability.
