Hub-and-spoke airline network design with uncertainty demand

In order to adapt to uncertainty demand for hub-and-spoke airline network,the influence factors and distribution characteristics of long-distance and short-distance traffic demands were analyzed.A stochastic and capacitated hub-and-spoke airline network design model was proposed.The model was transformed into chance-constrained programming model and solved by stochastic simulation-based genetic algorithm.Taking 15 cities of Chinese airline network planning as an example,hub-and-spoke network design with 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 long-distance traffic demand,the route choice of short-distance demand changes greatly.The hub-and-spoke airline network with uncertainty demand has lower minimum transportation cost,and can better reflect true network performance.
