Choice of determining weights method in fuzzy synthetic evaluating model for water quality

doi:10.7523/j.issn.2095-6134.2011.2.006

Abstract

Abstract:

By taking monitoring data of Chagan Lake as an example, fuzzy synthetic assessment was conducted using the principal component weighting, exceeding standard weighting, and analytic hierarchy process. Results show that the principal component weighting can truly reflect the values of various factors; exceeding standard weighting gaves heavier weights to the polluting factors; and the weight values are influenced by subjectivity in analytic hierarchy process.

Key words: fuzzy synthetic evaluating, determining weights method, principal component weighting, analytic hierarchy process, SPSS software
