Abstract: In this paper, we first define vague parameterized vague soft sets (vpvs-sets) and study some of their properties. We then introduce vpvs-aggregation operator to form vpvs-decision making method that allows constructing more efficient decision processes. Finally, we give a numerical example to show the method working successfully for problems containing uncertain data.
