- Abstract:
- Urban water supply faces many safety risks such as hydraulic safety risk and water quality safety risk, and the arrangement scheme of pipe network monitoring points considering only a single risk factor has certain limitations. Based on comprehensive consideration of various potential risks such as hydraulic condition and water quality that affect water supply safety, a system for comprehensive evaluation of water supply safety was established to form a node safety risk index by using fuzzy analytic hierarchy process, and a multi-objective optimization model of monitoring point location was established, which took the maximum node coverage security risk index, the maximum node coverage water quantity and the minimum number of monitoring points as the objective functions. The hydraulic and water quality model of pipe network in a typical mountainous city, Chongqing was constructed by EPANET 2.0 software, and the multi-objective mathematical model was solved and analyzed by NSGA-Ⅱ algorithm. The optimization model of pipe network monitoring point arrangement based on comprehensive safety evaluation was capable of effectively exploring all kinds of safety risk information, covering high-safety risk nodes, and obtaining a more uniform distribution of monitoring points, which could provide reference for the monitoring point arrangement of urban water supply network.
