Abstract

This paper introduces a concept of a type-2 intuitionistic triangular fuzzy number (T2ITFN) and its operating rules based on a type-2 intuitionistic fuzzy set and an intuitionistic triangular fuzzy number, thereafter a T2ITFN weighted arithmetic averaging (T2ITFNWAA) operator, a T2ITFN ordered weighted averaging (T2ITFNOWA) operator, a T2ITFN hybrid aggregation (T2ITFNHA) operator are proposed. Considering the diversities of risk attitudes and sensitivities among decision-makers with limited rational behaviors, a prospect effect and a prospect value function of T2ITFN are defined as constructing a prospect T2ITFNHA (PT2ITFNHA). With respect to a multiple criteria group decision making problem, in which decision-makers' weights are known, criteria weights are uncertain, and position weights of PT2ITFNHA are calculating by a normal distribution-based method, an approach for multiple criteria group decision making based on a novel prospect T2ITFNHA operator is proposed. In the approach, a prospect value function of T2ITFN is aggregated by using the PT2ITFNHA operator; a grey system theory model is then built to determine the criteria weights and a ranking of alternatives is obtained by calculating a proposed set pair score function. Finally, a practical example illustrates the practical application background of T2ITFN and shows the feasibility and effectiveness of the proposed approach.
