Abstract: Aiming at the dynamic multi-attribute decision making problems, which period weights and attribute weights for each period were specified and attribute values in different periods were expressed in triangular fuzzy numbers, an extended decision making method based on Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) was presented. According to the basic idea of traditional VIKOR, by integrating the operational laws of triangular fuzzy numbers, the evaluation values for each scheme in different periods were calculated. The specified Dynamic Triangular Fuzzy Weighted Averaging (DTFWA) operator was used to integrate the evaluation values in different periods so as to obtain the total evaluation values of each scheme. Based on the possibility degree formula for the comparison between triangular fuzzy numbers, the ranking of scheme volum was obtained. A numerical example was provided to demonstrate the practicality and feasibility of the proposed method.
