Assessment of Criticality in Water Distribution Networks via Complex Network Theory

Processes, Год журнала: 2025, Номер 13(2), С. 408 - 408

Опубликована: Фев. 4, 2025

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.

Sustainability Assessment of a Low-Income Building: A BIM-LCSA-FAHP-Based Analysis

Buildings, Год журнала: 2022, Номер 12(2), С. 181 - 181

Опубликована: Фев. 5, 2022

The construction industry is one of the most significant consumers environmental resources worldwide. Faced with need to produce new buildings, but without further burdening environment, attempts improve social, economic, and indicators have turned attention building in recent decades. objective this research develop a novel framework assess sustainable choice materials applied low-income according three pillars Triple Bottom Line (TBL). A BIM-LCSA-FAHP-based model was proposed creation nine different scenarios, where structure (precast concrete, cast-in-place structural masonry), painting (PVA water-based acrylic), roofing (ceramic fiber cement tiles) varied. procedure consists elaboration 3D Building Information Modeling (BIM) model, for which parameters described above were evaluated Life Cycle Sustainability Assessment (LCSA)-TBL-based criteria, divided into ten sub-criteria, that includes: (1) (acidification, eutrophication, global warming, ozone depletion, smog formation, primary energy, non-renewable mass total), (2) economic (construction cost) (3) socio-political issues (community impact). Finally, Fuzzy Analytical Hierarchy Process (AHP) used as multi-criteria decision-making technique helps aggregating classifying impacts each scenario sustainability index (SI). Regarding best option construction, results indicated precast concrete when combined acrylic paint tiles (scenario 3) proved be advantageous achieved first place (SI) developed work. This methodology replicable typologies several categories materials, making it robust decision-aiding tool engineers, architects, decision makers.

Design and Implementation of Node Degree Centrality Computing of Network Security Database Based on Knowledge Graph

Security and Privacy, Год журнала: 2025, Номер 8(1)

Опубликована: Янв. 1, 2025

ABSTRACT With the development and popularization of network technology, security issues are increasingly being valued. The application knowledge graph technology in can significantly enhance level protection, assist users relevant departments understanding overall trends vulnerabilities, swiftly identify respond to threats. To improve analysis response capabilities threats, developing methods for identifying key nodes is urgent. This research focuses on degree centrality calculation method a database based graphs. We propose novel approach computing node within graph‐based database. comprises two main components: weight score calculation. Additionally, we have developed importance ranking module derived from CVE database, providing faster more accurate solution compared manual methods. then discuss significant value promising prospects field protection future work.

A fuzzy group decision-making model for Water Distribution Network rehabilitation

Urban Water Journal, Год журнала: 2024, Номер 21(3), С. 364 - 379

Опубликована: Янв. 4, 2024

Group Decision-Making (GDM), though could aid water companies in determining the Pipeline Rehabilitation Plans (PRPs) any network size, can impose uncertainties on PRPs due to different viewpoints of decision-makers. Thus, it should be determined when GDM ignored or considered for PRPs. To address this problem, a Fuzzy model was developed assess 10 scenarios combination with 7 size. Hence, by participating experienced experts countries, were various sizes case study. The results indicated that fewer pipes, whereas, more pipes. In addition, found groups decision-makers had less effect pipes prioritization, but influence rehabilitation strategies. While, decision-makers, have reverse effect.

Fuzzy logic-based integrated performance evaluation of a water distribution network

Journal of Water Supply Research and Technology—AQUA, Год журнала: 2022, Номер 71(3), С. 490 - 506

Опубликована: Фев. 26, 2022

Abstract A water distribution network (WDN) is an essential component of urban supply scheme to deliver safe and adequate consumers under various operational conditions. This study focuses on the performance evaluation WDN using fuzzy logic-based aggregation reliability, resilience, vulnerability indices. To assess individual indicators, this advocates pressure-dependent analysis (PDA) for hydraulic simulation. Furthermore, it a rule-based aggregated index (API) that will outcome in linguistic form help decision-maker prioritize maintenance WDN. The proposed method illustrated with real-time part Dire Dawa city Ethiopia. It has been found API values are 0.721 0.624, respectively, normal abnormal conditions, which just satisfactory. noticed nodes J4, J44, J47, J49 critical from overall low API. Efforts should be made improve residual chlorine conditions at these increase felt such methodology decision-makers existing

Опубликована: Окт. 31, 2023

The primary objective of this work is to introduce a novel approach that modifies the method for analyzing and assessing risk water supply network failure. aligns with recommendations from World Health Organization European Union regarding reliability safety consumers. presented in distribution subsystem was based on vulnerability identifying (VIM) involves determination index (VI). VIM factors considered encompass failure rate, chemical stability water, issues related corrosion properties subsystems. obtained assessment includes parameters such as probability hazard occurrence, consequences these hazards, them. This concept evaluated using real operational data subsystem. estimated level, under given operating conditions, indicates its acceptability.
