Abstract Optimizing the design and operation of urban water distribution networks (WDNs) is a complex, nonlinear problem. The optimization of WDNs can be performed for the pumping schedule, the location and elevation of reservoirs, the physical characteristics of pipes, and the placement of pressure-reducing valves, among other objectives. This study applies the anarchic society optimization (ASO) algorithm to find the optimal location and elevation of auxiliary tanks in urban water networks. The ASO is validated with mathematical benchmark functions, and is implemented to determine the location and elevation of auxiliary tanks in two urban water networks. The fuzzy reliability index for urban water network ranges between 74 and 79%, which is close to the global optima. The ASO exhibited better performance optimizing the reliability of WDNs than the genetic algorithm.

Abstract Prior work investigated the use of biological food webs as a source of quantitative guidance to balance the efficiency and redundancy in industrial water distribution networks. Urban water distribution networks, however, present unique challenges that prevent a direct replication of the bio-inspired methods used for industrial network settings. Many of the benefits bio-inspiration can impart on human networks, including resilience-related improvements, makes use of reuse- and recycling-related pathways — maximizing the use of all available value in the network. This work looks at the application of bio-inspiration to urban water network settings, modeling these networks to include local wastewater treatment options and testing actor aggregation options to best fit the ecosystem analogy. The results suggest that biological ecosystems do in fact have characteristics that can be beneficial to urban water distribution, but a change of system boundaries is required to recognize their potential.

In recent years, the SCADA (supervisory control and data acquisition) systems are applied widely for water distribution networks, where the auto-control valves are used to reduce the excessive water pressure of each node for further leakage control. In this paper, first the existing optimal location models of valves are briefly introduced, whose shortcomings are proposed. Then a new method based on direct hydraulic analysis theory of the mass conservation of nodes and the energy conservation of loops is available for optimal location of auto-control valves. Finally taking the water network of Tianjin Port Free Trade Zone as an example, valve location problem is illustrated, which shows the feasibility of the method.

Svm Model

To evaluate the security of urban water distribution network, one model based on LS-SVM was put forth. On the basis of summary and analysis of influential factors for urban water distribution network security, a set of indexes used in the evaluation model above was constructed. The nonlinear mapping between the water distribution networks security classification and its conditions were learned from the finite samples and a water distribution network example was simulated using this model. In addition, the BP ANN model was used to simulate the same example. Through the analysis of the result of the actual security level, the security level acquired by the LS-SVM model and BP ANN model, it may be found that the result acquired by the LS-SVM model has high accuracy, and may used in actual engineering.
