Based on the characteristics of urban water supply system, the urban pipe network security assessment system was established, and then AHP method combined with fuzzy evaluation was used to carry out a comprehensive security assessment for the leakage of the urban pipe network. By calculating a real case and analyzing various leakage causes and their impact,(More)
In this article, the evaluation technology is proposed for optimal operation scheme based on safety water supply, in order to verify the security and economy of the optimal operation scheme and provide the evidence for optimal operation decision-making. Four evaluation indices, named flow coincidence, pressure coincidence, pump efficiency and direct power(More)
The water supply pipe network security issue is the safety of drinking water problem of urban residents faced the basic problem, in order to quantitatively study the safety of urban water supply pipe network level. Using the improved AHP built determination matrix and determined the weight of each index, using multi-level fuzzy assessment method to evaluate(More)
