A stochastic and capacitated hub-and-spoke airline network design model was proposed. The model w as transformed into chance-constrained programming model and solved by stochastic simulation-based genetic algorithm. Taking 15 cities of Chinese airline netw ork planning as an example, hub-and-spoke network design w ith uncertainty demand was analyzed. Analysis result indicates that hub locations with certainty and uncertainty demands are almost same in the reasonable range of hub numbers, but compared with
