USING THE ELECTRE II METHOD TO APPLY AND ANALYZE THE DIFFERENTIATION THEORY

The ELECTRE evaluation method is widely recognized for high-performance policy analysis involving both qualitative and quantitative criteria. However, a critical advantage of this evaluation method is its capacity to pinpoint the exact needs of a decision maker and suggest an appropriate evaluation approach. The discordance indices of modified ELECTRE evaluation method are used to explain the significance of modified evaluation standards. The ELECTRE II evaluation method, applied to case simulation, helps analyze the potential effects triggered by the absolute value of the maximum differentiated performance and the absolute value of the sum of differentiated performance under two discordance index evaluation standards. In general, using the ELECTRE evaluation method in the absence of a differentiation process may produce results opposite to those desired by a decision maker. In addition to discussing the above phenomena, the author attempts to explain the policy-making process using a case study of land redevelopment in Heping Harbor Zone, Keelung, Taiwan, ROC
