Optimization analysis of seismic damage evaluation model based on fuzzy analytical hierarchy process

摘要

The establishment of fuzzy judgement matrix plays an important role in the accuracy of seismic damage assessment using Fuzzy Analytic Hierarchy Process (FAHP). The optimization analysis is mainly focus on the fuzzy judgement matrix because the important value of each two influencing factors is given by the seismic damage experience and seismic design theory subjectively. In this paper, the initial fuzzy judgement matrix has been set up and the assessment results are given by them. Optimization analysis of single factor is carried out in the adjustment of fuzzy judgement matrix to obtain the best assessment results under the assumption of keeping the fuzzy evaluation matrix of index layer unchangeable. The result shows that accuracy of assessment calculated by the optimal fuzzy judgement matrix has been improved by 1.48%.
