Hydraulic engineering safety evaluation method based on improved fuzzy analytic hierarchy process

Abstract

The invention discloses a hydraulic engineering safety evaluation method based on the improved fuzzy analytic hierarchy process, and mainly solves the problem that the evaluation result of an existing water conservancy project safety evaluation method is inaccurate. The method comprises the following steps: (S1) determining a factor set of an evaluation object; (S2) determining an evaluation grade set of the evaluation object; (S3) performing single-factor evaluation on the evaluation object to form a membership matrix; (S4) determining a factor weight vector of the evaluation object to obtain a judgment matrix, and carrying out numeralization or normalization on the evaluation grade set; (S5) obtaining a comprehensive evaluation result vector matrix; and (S6) performing judgment according to a membership degree maximum principle, or solving a membership degree grade by using weighted average to obtain a comprehensive judgment value. According to the method, an improved fuzzy comprehensive evaluation method based on natural index e0 / 4-e8 / 4 scales is adopted, safety evaluation is carried out on the water conservancy project, subjective weights and objective weights of bottom layer evaluation indexes are optimized, the subjective weights are corrected, and weight distribution of the indexes is more reasonable.

Description

technical field [0001] The invention relates to a water conservancy project safety evaluation method, in particular to a water conservancy project safety evaluation method based on an improved fuzzy analytic hierarchy process. Background technique [0002] Water conservancy engineering is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. It is also called water engineering. Water is an indispensable and precious resource for human production and life, but its natural existence The state does not fully meet the needs of human beings. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of people's life and production for water resources. Water conservancy projects require the construction of dams, dikes, Spillways, sluices, water intakes, channels, raftways, fishways and other types ...
