Water supply network failure updating strategy method based on multi-target prediction model

Abstract

The invention discloses a water supply network failure updating strategy method based on a multi-target prediction model, and relates to the technical field of water supply networks, and the method comprises the following steps: carrying out the data collection in advance, and collecting and filtering basic data needed by model establishment and scheme prediction; establishing a prediction model and a pipe network aging and failure prediction model, carrying out pipe explosion severity analysis, and carrying out generation and quantitative evaluation of a pipe network updating strategy scheme. Establishment of the water supply pipe network failure prediction model is an effective way for optimizing a pipe network updating and transformation strategy and reducing the pipe explosion risk, and the scientific statistical model is combined with the economic factors to be applied to formulation of a multi-target pipe network updating scheme, so that pipe network failure can be effectively prevented, and the use efficiency of transformation funds can be improved, and the pipe network asset efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water supply pipe network, in particular to a method for updating a water supply pipe network failure update strategy based on a multi-objective prediction model. Background technique [0002] Urban water supply network is an indispensable and important part of urban infrastructure, accounting for about 70-80% of the total asset value of water companies. Because the leakage and failure rate of the urban water supply pipe network will increase year by year with the extension of the service life, resulting in burst accidents and leakage of the water supply pipe network, affecting the safety of urban water supply and residents' water supply services, and reducing the efficiency of pipe network operation . Therefore, the timely renewal and transformation of urban water supply pipe network is particularly important. [0003] At present, the renewal of urban water supply pipe network is mostly based on the ex...

AI Technical Summary

Problems solved by technology

[0003] At present, the renewal of urban water supply pipe network is mostly based on the experience of water company operation and management personnel or the static maintenance information recorded by the pipe network information system. The analysis parameters are single, and it is impossible to accurately formulate medium and long-term renewal plans. The degree of improvement in the burst rate of the water supply pipe network is difficult to quantify the input and output of the pipe network transformation, which is not conducive to the precise use of funds
