摘要：Based on the theory of attribute mathematics, this paper improves on the attribute interval evaluation theory. The main feature is that the evaluation index is an interval rather than a certain value. Using single index attribute analysis of the upper and lower limits of the interval, the paper proposes two calculation methods for the multiple index synthetic attribute measure. Based on the original AIET software, we develop a new set of software packages (NEW AIET) that can automatically complete a large number of calculations in a few seconds. Via engineering application, the accuracy and feasibility of geological disaster risk assessment are verified and can be used to better evaluate engineering disaster risk. © 2020, Springer Nature Switzerland AG.
