Abstract: In the optimization design of single layer latticed domes,the used mathematical models without considering uncertain factors have some extents of limitations.Based on the considering of fuzzy and random quality of each design parameter of single layer latticed domes,a new multi-objection optimization model is established.In this model,the fuzziness of multi-objective function and the stress control criterion are solved.The computation results for single layer latticed domes demonstrate that the model is reasonable and feasible.

Key words: single layer latticed dome； fuzzy optimization； fuzzy and reliability；
