Description
Summary:The set pair analysis is a system analysis method to deal with uncertain problem. The concepts of the main same, supper same, assimilation degree and the new determining levels law are stipulated to make up for the defects of routine set pair analysis about the weights and determining levels law based on the theories of improved entropy weight and set pair analysis malleability. The method to determine system level and rank order projects by the main same and assimilation degree was put forward, and then, the multi-factors degree set pair analysis fuzzy evaluation model (EWMFSPAFM) has been suggested. A study under taken groundwater environment evaluation as demonstration, the water resources are evaluated by the EWMFSPAFM. And the results are compared with the results of the routine set pair analysis evaluation model and improved set pair analysis evaluation model. It is showed that the EWMFSPAFM is structure simple, calculation easy, result practical and reasonable, the method feasible and reliable.
