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.
