Study on evaluation of the foreign trade sustainable development with interval-valued intuitionistic fuzzy information

In this paper, we investigate the MSM operator and extend the MSM operator to interval-valued intuitionistic fuzzy environment and develop the interval-valued intuitionistic fuzzy Maclaurin symmetric mean (IVIFMSM) operator. Using IVIFMSM operator, a novel algorithm to MADM problems by utilizing in terval-valued intuitionistic fuzzy information is developed. In the end, we provide an example for evaluating the foreign trade sustainable development is given.
