Abstract: A method is presented to deal with the fuzzy multiple attribute decision making problem with preference values on alternatives，in which the information about attribute weights is incomplete，the attribute values and the preference information on alternatives are given in the form of intuitionistic fuzzy numbers.According to the preference information on alternatives given by decision makers，multi-objective programming model is constructed to obtain the attribute weights.Then，intuitionistic fuzzy weighted arithmetic averaging operator is used to aggregate the intuitionistic fuzzy information corresponding to each alternative，and the alternatives are ranked by the score function.Finally，an illustrative example is given to demonstrate the practicality and effectiveness of the proposed method.

Key words: multiple attribute decision making, intuitionistic fuzzy numbers, objective programming model, weighted arithmetic averaging operator
