Water distribution networks (WDNs), which are responsible for delivering water of adequate quantity and quality, vulnerable to threats such as leaks, pipe breaks, contaminant intrusions. Hence, it is important identify critical network elements develop more assertive maintenance strategies systems. This paper aims perform a risk assessment on leaks breaks support the identification in supply To this end, complex theory (CNT) applied an alternative conventional approaches that rely multiple hydraulic simulations. Metrics robustness, redundancy, centrality, connectivity used analyze graphs representing WDNs. Failures modeled using simulations evaluate their impact parameters pressure flow. CNT metrics then applied, including shortest path calculations between sources demand vertices assess importance, vertex centrality node influence network. The results compared with outcomes CNT-based analyses. Multi-criteria analysis employed determine asset priority, considering failures associated impacts system. highlight novel approach shifts focus from state-based assessments topology-driven analysis, reducing uncertainties inherent models.

Systems engineering is an ubiquitous discipline of Engineering overlapping industrial, chemical, mechanical, manufacturing, control, software, electrical, and civil engineering. It provides tools for dealing with the complexity dynamics related to optimisation physical, natural, virtual systems management. This paper presents a review how multi-agent complex networks theory are brought together address management problems. The also encompasses current future research directions both theoretical fundamentals applications in industry. made by considering trends such as mesoscale, multiscale, multilayer along state-of-art analysis on network intelligent networks. Critical smart infrastructure, manufacturing processes, supply chain instances topics which this literature highly relevant.

A water distribution network (WDN) is an indispensable element of civil infrastructure that provides fresh for domestic use, industrial development, and fire-fighting. However, in a large complex network, operation management (O&M) can be challenging. As technical initiative to improve O&M efficiency, the paradigm “divide conquer” divide original WDN into multiple subnetworks. Each subnetwork controlled by boundary pipes installed with gate valves or flow meters control volume entering leaving what are known as district metered areas (DMAs). Many approaches creating DMAs formulated two-phase procedures, clustering sectorizing, called partitioning (WNP) general. To assess benefits drawbacks WDN, we provide comprehensive review various state-of-the-art approaches, which broadly classified as: (1) Clustering algorithms, focus on defining optimal configuration DMAs; (2) sectorization physically decompose selecting installing valves. We also overview emerging problems need studied.

To date immunity to disruptions of multi-scale urban road networks (URNs) has not been effectively quantified. This study uses robustness as a meaningful - if partial representation immunity. We propose novel Relative Area Index (RAI) based on traffic assignment theory quantitatively measure the URNs under global capacity degradation due three different types disruptions, which takes into account many realistic characteristics. also compare RAI with weighted betweenness centrality, traditional topological metric robustness. employ six case studies for this comparison. Our analysis shows that is more effective when suffer from disruptions. improved effectiveness achieved because RAI's ability capture effects network characteristics such topology, flow patterns, link capacity, and travel demand. Also, results highlight importance central management method may provide benchmark tool comparing URNs, facilitates understanding improvement planning URNs.

The detection of contaminant intrusion into a water-distribution network (WDN) is difficult issue due to uncertainty related the type injected contaminant, source location, and time. placement water quality sensors has received increasing interest in last years, it still represents an open problem great challenge for researchers utilities. Efficient numerical techniques are needed support any contamination warning system (CWS) design. These require well-calibrated hydraulic model WDN deal information, both which often unavailable In addition, as size increases, choice effective sensor becomes computationally intractable problem. This paper introduces methodology utilities design CWS without use but just exploiting knowledge topology WDN. To ensure complete coverage network, method relies on priori clustering installation at most central nodes each cluster, selected according different topological centrality metrics. procedure tested benchmark real serving town close Naples, Italy. solutions obtained with criteria terms time, likelihood, redundancy, population exposed through ingestion.

The uneven spatial and temporal distribution of water resources has consistently been one the most significant limiting factors for social development in many regions. Furthermore, with intensification climate change, this inequality is progressively widening, posing a critical challenge to sustainable human societies. construction large-scale projects become crucial means address contradictions between supply demand. Thus, evaluating functional aspects source network structures systematically planning layout engineering measures scientifically reasonable manner are pressing issues that require urgent attention current research efforts. Addressing this, our study takes Erhai Lake basin surrounding areas southwest China as area combines landscape ecology analysis theory methods propose method into account both structure node characteristics. Based on methodology, we analyze connectivity characteristics networks region under (2020) future (2035) scenarios. results show there were 215 nodes 216 links 2020; implementation series conservancy projects, planned 2035 will increase by 122 163 links, regional be significantly improved. Also, identify some key network, have obvious decentralization compared 2020. And, based degradation analysis, find measures, resilience strengthened 2035, stronger risk tolerance. This extends quantitative representation characteristics, which can provide useful reference optimization.

This paper proposes a combined management strategy for monitoring water distribution networks (WDNs). is based on the application of network partitioning (WNP) creation district metered areas (DMAs) and installation sensors quality monitoring. The proposed methodology was tested real WDN, showing that boundary pipes, at which flowmeters are installed to monitor flow, good candidate locations sensor installation, when considered along with few other nodes detected through topological criteria partitioned WDN. option considering only these potential locations, instead all WDN nodes, inside multi-objective optimization process, helps in reducing search space possible solutions and, ultimately, computational burden. obtained effective affected population detection time contamination scenarios, increasing likelihood redundancy system. Last but most importantly, offer benefits terms costs. In fact, installing alongside flowmeter present between two adjacent DMAs yields managerial advantages associated closeness devices. Furthermore, economic due possibility sharing some electronical components data acquisition, saving, transmission derived.
