Tehran Seismic Vulnerability Assessment Due to the North City Fault by a Multi Attribute Decision Making Approach Based on Evidential Reasoning

Seismic vulnerability assessment is a multi attribute decision making problem based on geospatial information where the weight and importance of each of the criteria is determined by experts. Geospatial information deals with some uncertainties. One of the ways for integrating this information is evidential reasoning theory. The theory is based on independent assumption of information sources which is not correct in many cases including geospatial information. This paper propose a new method of intelligent decision making based on cautious conjunctive rule of combination for seismic vulnerability assessment in Tehran by assuming activation of the north fault. Also assumed that activation of this fault does not affect on activation of other faults in Tehran. This combination rule does not need independent assumption of information sources and can be used on data sources that have overlapping information and uncertainty.
