This study explores the application of using the interval-valued intuitionistic fuzzy soft sets (IVIFSS) approach to the multi-criteria group decision making problem. Firstly;
we define the concept of the IVIFSS value vector;
including the IVIFSS weighted averaging;
the optimistic IVIFSS value and the pessimism IVIFSS value. Then;
some of their desirable properties are investigated in detail. Furthermore;
we prove that the decision makers;
as the parameter sets;
and their IVIFSS value vector;
as mapping rule;
may be consider as a new IVIFSS for all decision makers and the vector of this IVIFSS could be considered as the valuation of the alternatives that all the decision makers decide;
whose score functions could be rank the alternatives. Finally;
an approach to multicriteria group decision making based on IVIFSS is given and an illustrative example is employed to show the validity of this approach;
