“…Falasca & Zobel (2012) approached the specific problem of volunteer assignment which, until now, has been equally neglected. In their paper, Turner et al (2012) proposed a water distribution using pressurized zones to satisfy the demand in uncovered areas. Sheu (2010) and Xu et al (2010) presented a very interesting and useful proposition to manage and forecast demand.…”

In the last 20 years, Emergency Management has received increasing attention from the scientific community. Meanwhile, the study of relief distribution networks has become one of the most popular topics within the Emergency Management field. In fact, the number and variety of contributions devoted to the design or the management of relief distribution networks has exploded in the recent years, motivating the need for a structured and systematic analysis of the works on this specific topic. To this end, this paper presents a systematic review of contributions on relief distribution networks in response to disasters. Through a systematic and scientific methodology, it gathers and consolidates the published research works in a transparent and objective way. It pursues three goals. First, to conduct an up-to-date survey of the research in relief distribution networks focusing on the logistics aspects of the problem, which despite the number of previous reviews has been overlooked in the past. Second, to highlight the trends and the most promising challenges in the modeling and resolution approaches and, finally, to identify future research perspectives that need to be explored.

“…Моделі змішаного цілочисельного нелінійного програмування (Mixed Integer Nonlinear Programming -MINLP) поєднують властивості MIP та NLP, використовуючи цілочисельні та неперервні змінні разом з принаймні одним нелінійним обмеженням чи нелінійною цільовою функцією [51,52]. Для моделювання водної мережі пропонується задача мінімізації зважених витрат дефіциту води і перевезення води вантажівками [51], яка лінеаризується і розв'язується як MIP.…”

Critical infrastructure of interdependent modern sectors is increasingly relying on cyber systems and cyber infrastructures, which are characterized by growing risks of their cyber components, including cyberphysical subsystems. Therefore, cybersecurity is important for the protection of critical infrastructure. The search for cost-effective ways to increase or improve the security of cyber infrastructure is based on optimization models and methods of cyber infrastructure stability, safety, and reliability. These models and methods have different fields of application and different directions, not necessarily focused on the cyber infrastructure resilience. The growing role of information and communication technologies has influenced the concept of security and the nature of war. Many critical infrastructures (airports, hospitals, oil pipelines) have become potentially vulnerable to organized cyber attacks. Today, the implementation of the major state function of defense and security largely depends on the successful use of information and communication technologies as modern competitive (final and intermediate) dual-use products used by different people for different purposes. Game theory is increasingly used to assess strategic interactions between attackers and defenders in cyberspace. Game research and modeling combinations are combined to study the security of cyberspace. In cyberspace, the arsenal of weapons is built by finding more vulnerabilities in the defense of the target. Vulnerability is a weakness in the security procedures of the system, the design of the system or its implementation, as well as in the organization of internal control, which may be used by the source of the threat. The dynamic nature of vulnerabilities means that they are constantly changing over time. Detecting a vulnerability by a defender reduces the effectiveness of the attacker’s cyber weapon, which exploits the vulnerability, and increases the target protection. Game theory has been applied to many issues, including resource allocation, network security, and human cooperation. In cyberspace, there is often a placement game where the attacker and the defender decide where to allocate their respective resources. Defender’s resources can be security infrastructure (firewalls), finance, training. For example, a network administrator might look for a resource allocation that minimizes the risk of (cyber) attacks and at the same time protects against cyberattacks. The attacker has limited resources and is at risk of being tracked down and punished. The problem of resource allocation in cyberspace can be formulated as a game-theoretic problem, taking into account the concept of common knowledge and the problem of uncertain observability.

“…Previous researches on water supply networks have been performed in the aspects that follow: (1) Seismic response and seismic reliability of buried water pipelines [10][11][12]; (2) seismic connectivity reliability, hydraulic function reliability, and seismic service performance [13,14]; (3) performance-based seismic design [15,16]; (4) post-earthquake function recovery [17][18][19][20]. The above aspects belong to seismic performance research or optimal design of the WSN in earthquake scenarios, which are carried out by the way of theoretical calculation, numerical simulation, and intelligent optimization algorithms [10,20,21], taking external environments (i.e., seismic hazard and site types) and structural attributes of pipes into account. In reality, however, the information that we obtain is incomplete, and the earthquake or the site condition also has highly random characteristics.…”

Historical seismic events show that water supply networks are increasingly vulnerable to seismic damage, especially in a violent earthquake, which leads to an unprecedented level of risk. Evaluation of vulnerability to seismic hazards can be considered as one of the first steps of risk management and mitigation. This paper presents a stochastic interpolation-based fractal model for assessing the physical vulnerability of urban water supply pipelines. Firstly, based on the formation mechanism of natural disaster risk and the concept of seismic vulnerability, the most representative factors were selected as the vulnerability evaluation indices, and the classification criterion of each index was teased out according to the earthquake damage investigations and researches on the aseismatic behavior of water supply pipelines. Secondly, considering the randomness of vulnerability to earthquake hazards, the test data set was produced by way of stochastic interpolation according to the uniform distribution, on the basis of the classification criterion. The fractal dimensions of all of the indices were calculated based on the test data set. The fractal interpolation diagnosis function for identifying the vulnerability levels of pipelines to earthquake disasters was established. Finally, the application of the proposed model to a real water supply network and its comparative analysis showed that the water supply network was basically in a medium vulnerability level. Through the case study verification, we could find that the model was theoretically and practically feasible. This study helps to gain a better understanding of the extents of potential vulnerability levels of water supply pipelines. It can provide technical support for disaster prevention plans of urban water supply networks.
