A New MADA Methodology Based on D Numbers

Multiple attribute decision analysis (MADA) is still a hot issue. In order to represent information of attributemore flexibly and intuitively, quantitative and qualitative data are involved in real-world applications. In this paper, a new methodology to deal with MADA problem based on D numbers is proposed. Different with other existing methods, the new proposed method is more simply and straightforward, due to the integration property of D numbers. A numerical example of car assessment is used to demonstrate the effectiveness of proposed method.
