A method and system for scoring the safety quality of drinking water

By constructing a multi-level evaluation index system and an improved AHP (Analytic Hierarchy Process) method, combined with nonlinear formulas and penalty mechanisms, a scientific quantitative assessment and dynamic risk warning of drinking water safety quality were achieved. This solved the problems of insensitivity and insufficient transparency of scoring results in traditional methods, and provided visualized water quality scoring results.

AI Technical Summary

Technical Problem

Existing technologies are insufficient for scientific and unified quantitative assessment of drinking water safety and quality. There is a lack of coordinated evaluation between national standards and enterprise internal control standards. The public's demand for water quality transparency is difficult to meet. Traditional methods are subjective in weight allocation, the scoring results are not sensitive to indicators exceeding the standard, and there is a lack of dynamic adjustment mechanisms.

Method used

A multi-level evaluation index system was constructed, and the health and sensory comprehensive weights of water quality indicators were calculated using nonlinear formulas and an improved AHP (Analytic Hierarchy Process). A penalty mechanism was also introduced to form a comprehensive water quality safety score.

Benefits of technology

It enables a comprehensive quantitative assessment of drinking water safety and quality, taking into account both health risks and sensory experience, dynamically adjusting scoring results, providing visualized water quality risk warnings, and meeting the needs of enterprise management and public inquiry.

Abstract

The application discloses a kind of drinking water safety quality scoring methods, comprising: constructing multilevel evaluation index system, and collecting the monitoring data of each water quality index;According to the monitoring data, the compliance of each water quality index is determined, and the basic score of each water quality index in the health level and the sensory level is calculated using a nonlinear formula;The improved AHP analytic hierarchy process is used to determine the health comprehensive weight and the sensory comprehensive weight of each water quality index;According to the basic score of each water quality index in the health level and the sensory level and the corresponding comprehensive weight, the health level score and the sensory level score are obtained by weighted summation, and the final comprehensive water quality safety score is calculated by introducing a penalty mechanism.The application solves the shortcomings of traditional water quality evaluation methods systematically through multidimensional index design, objective weight calculation, fine scoring mechanism, standard coordination and visual result output, and provides a scientific and efficient quantitative tool for drinking water safety management.
