A Novel Regional Ecological Assessment Technology Based on Improved Electre Method

Abstract

A lot of efforts have been made in ecological assessment and applications. At present, Chinese government attaches great importance to regional economic development, so this research takes China as the research object. For this reason, a novel regional ecological assessment technology is proposed based on improved ELECTRE method. In the improved ELECTRE method, concordance index, nonconcordance index, credibility index, consistent credibility, non-consistent credibility and net credibility are defined firstly, and the preference matrix, the relation of group individuals is also defined. Based on these definitions, it can be sorted for the quality of all alternatives according to the net credibility. Experimental results suggest that the proposed improved ELECTRE method is feasible and valid to the regional ecological assessment.
