Abstract: Based on the uncertainty of attribute value information and the different risk attitudes of decision-makers towards gain and loss, an extended TODIM(an acronym in Portuguese of interactive and multi-criteria decision making)under single-valued neutrosophic linguistic environment is proposed. First, the uncertainty in attribute value information can be quantified directly by using single-valued neutrosophic language set. Second, based on the extended language scale function, the distance measure and aggregator of single-valued neutrosophic linguistic numbers are defined. Based on these, weights are calculated by standard deviation and ranks are obtained by the TODIM method. Finally, the practical application process of the proposed method is illustrated by the case of energy-saving service company selection, which verifies the feasibility and effectiveness of the method.

Key words: single-valued neutrosophic linguistic set, linguistic variable, TODIM method, dominance degree
