In order to solve the problem of inaccuracy of water data obtained by single sensor,homogeneous data are collected by multi-sensor.Firstly,according to the characteristics of hesitant fuzzy set theory,the data is fused in the form of fuzzy matrix,and the weight of attributes is determined by combined weighting method,and the comprehensive fuzzy evaluation index is used to evaluate water samples.Secondly,through the analysis of the shortcomings of the current water quality evaluation methods,a multi-attribute comprehensive evaluation model based on hesitant fuzzy theory is proposed on the basis of the original comprehen-sive fuzzy evaluation method,which solves the problem of the large amount of calculation in the original model.Finally,the score function is used to calculate the evaluation index under the hesitancy fuzzy multi-attribute comprehensive evaluation algorithm,and the comparison analysis with the traditional fuzzy comprehensive evaluation method verifies the rationality and effectiveness of the al-gorithm,which provides a more convenient and objective calculation method for the application of multi-index water quality evalua-tion.
