ABSTRACT This paper extends hesitant fuzzy sets to Triangular Hesitant Fuzzy sets based on the combination of the concepts of triangular fuzzy numbers and hesitant fuzzy sets and defines some operations on triangular hesitant fuzzy sets. Then, a decision-making method with linguistic assessments is proposed based on expected values of triangular hesitant fuzzy sets to solve the multi criteria decision-making problem in which the criteria weights are completely unknown and the criteria values for an alternative can be given by the linguistic values of triangular fuzzy numbers provided by a group of decision makers to transform them into triangular hesitant fuzzy sets. The criteria weights can be obtained by establishing a weight model based on the standard deviation of expected values from the triangular hesitant fuzzy decision matrix. Then by an approach of weighted expected values for alternatives, the ranking order of all the alternatives can be determined and the best one can be easily identified as well. Finally, a practical example the health hazard of traffic police is analysed to demonstrate the application of the proposed decision-making method. Keywords:- Triangular Hesitant Fuzzy Set, Triangular Fuzzy Number, Expected Value, Multi criteria Decision Making
