A Method of Handling Fuzzy Uncertainty of Data in Disaster Risk Assessment
Chongfu Huang · Journal of Taiyuan University of Technology · 2009
In this paper,for fuzzy uncertainty of data in disaster risk assessment,we suggested a method to granule the information.Its characteristics lie in exploiting the tolerance for imprecision,uncertainty and partial truth to achieve tractability,robustness,low solution cost and better support with reality.Its operation is simpler and more transparent compared with other methods.It provides an important theory and method to describe fuzzy uncertainty of data.In addition,theoretically,we discussed the benefits of suggested method by their representations based on probability and rough set.A simple application of estimating isoseismal area in disaster risk assessment fully demonstrates these advantages.
