Abstract: With respect to DEMATEL decision problems about initial matrix built by interval numbers, this paper proposes an attitudinal decision-making solution. Firstly, it analyzes the deficiency of the existing interval DEMATEL decision-making method. Then, it points out the one-sidedness on the process of standardization and the interval numbers might not satisfy algorithm of the lower and upper limit when the cause degree are calculated. And then it gives the steps of the solution. Finally, the new solution is illustrated by one case and compared with the existing interval DEMATEL method. It shows that the proposed method is simple and feasible and has some referential value.
