As an important part of linear algebra, determinant has a wide range of applications in real-world. Due to complexity of various systems, we usually encounter the poor information when obtaining the elements of determinant. In this paper, we defined grey determinant and proposed some fundamental computation rules. The proposed grey determinant can also be(More)
By combining the subjective and objective weights with the optimization technique, we construct an optimal model to make the deviation among the aggregated evaluation values as large as possible. Then the final weights of indices, which reflect the subjective and objective information, can be obtained. This approach is propitious to order schemes and select(More)
