Abstract

Abstract: During the process of emergency decision-making, information is frequently hesitant, fuzzy, and unbalanced, and decision makers often present their intuitive and rapid linguistic decision preference. In this work, an emergency decision-making method based on fuzzy linguistic TOPSIS is proposed. It combines the hesitant fuzzy linguistic term set (HFLTS) and 2-tuple linguistic expression to deal with words in highly uncertain context, which not only improves the elicitation of hesitant fuzzy information but also leads to linguistic results easy to understand by decision makers, and it could be helpful to making a rapid and accurate decision judgement. A case study verifies the feasibility and effectiveness of this method and proves its certain practical value.

Key words: emergency decision, flight alternate, hesitant fuzzy linguistic term set, 2-tuple, Mahalanobis distance-based TOPSIS method
