ABSTRACT
ABSTRACT: After initial research in the field of fuzzy finite elements has started in the middle of the nineties, different aspects of the problem have been considered, and continuous development has improved not only the capabilities but also the performance of the procedures. The improvement of the performance of fuzzy finite element analysis is still a big challenge. Vertex analysis with n uncertain parameters requires 2n deterministic analysis runs for each α-level that is considered. Another approach is optimisation, which is capable of predicting absolute maxima and minima. Unlike vertex analysis, the performance of optimisation procedures is unpredictable. There is a strong demand to reduce the computation time.
