Research on the Competitiveness of China's Tourism Trade in Service with Uncertain Linguistic Information

Abstract

The problem of evaluating the competitiveness of China’s tourism trade in service with uncertain linguistic information is the multiple attribute decision making (MADM) problems. In this paper, we investigate the multiple attribute decision making (MADM) problems for evaluating the competitiveness of China’s tourism trade in service with uncertain linguistic information. We utilize the interval uncertain linguistic weighted average (IULWA) operator to aggregate the uncertain linguistic information corresponding to each alternative and get the overall value of the alternatives, then rank the alternatives and select the most desirable one(s) by using the formula of the degree of possibility for the comparison between two uncertain linguistic variables. Finally, an illustrative example for competitiveness of China’s tourism trade in service with uncertain linguistic information is given.
