The concepts, operating rules and possibility degree of triangular type-2 fuzzy numbers are proposed. For the
problem of the multi-criteria decision making that the uncertainty of the criteria values is difficult to give with an accurate
number, triangular type-2 fuzzy number is used to show the decision information. And multi-criteria decision-making method
based on triangular type-2 induced OWA operator is proposed. In this method, the comprehensive criteria are attained by
using the triangular type-2 induced OWA operator. Then the ranking of alternatives is obtained by using the possibility
degree. Finally, an example analysis shows the feasibility and effectiveness of the proposed method.
