Abstract: With respect to interval-valued intuitionistic fuzzy multiple attribute decision making problems with preference information on alternatives and incomplete weight information,some operational laws of interval-valued intuitionistic fuzzy numbers,score function and accuracy function of interval-valued intuitionistic fuzzy numbers are introduced.An optimization model based on the minimizing deviation method,by which the attribute weights can be determined,is established.For the special situations where the information about attribute weights is completely unknown,another optimization model is established.By solving this model,a simple and exact formula can be used to determine the attribute weights.Then,the interval-valued intuitionistic fuzzy weighted averaging(IIFWA) operator is utilized to aggregate the interval-valued intuitionistic fuzzy information corresponding to each alternative.Based on the the score function and accuracy function of the interval-valued intuitionistic fuzzy number,a method for ranking the alternatives and selecting the most desirable one(s) is presented.Finally,an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness.
