  Interval valued bipolar fuzzy weighted neutrosophic set(IVBFWN-set) is a new
generalization of fuzzy set, bipolar fuzzy set, neutrosophic set and bipolar
neutrosophic set so that it can handle uncertain information more flexibly in
the process of decision making. Therefore, in this paper, we propose concept of
IVBFWN-set and its operations. Also we give the IVBFWN-set average operator and
IVBFWN-set geometric operator to aggregate the IVBFWN-sets, which can be
considered as the generalizations of some existing ones under fuzzy,
neutrosophic environments and so on. Finally, a decision making algorithm under
IVBFWN environment is given based on the given aggregation operators and a real
example is used to demonstrate the effectiveness of the method.
