A New Aggregating Operator for Linguistic Information Based on D Numbers

How to efficiently make decision under uncertain is a hot research topic. In this paper, a new aggregating operator for linguistic decision making based on D numbers is proposed. D numbers is a new mathematic tool to model uncertainty, since it ignores the condition that elements on the frame must be mutually exclusive. Compared with these existing aggregating operators, the new method is clear, concise and less computational complexity. A numerical example is used to demonstrate the effectiveness of the proposed method.
