Abstract: It is critical to repair the road network immediately to improve the emergency efficiency after earthquake. A mathematics model for post-earthquake road network repair scheduling under dynamic traffic flows (PRNRSDTF) is created and a hybrid genetic algorithm is provided to maximum the cumulative utilities. Finally, in the context of Wenchuan earthquake, a numerical example is abstract from Jingyang district of Deyang City to verify the reliability and validity of the proposed model and algorithm. The normal road network repair scheduling model without considering dynamical traffic flows is taken as a comparison. The results show that the PRNRSDTF model can provide more comparable strategy than normal road network repair schedule model and the cumulative utilities generated by road network repair are improved more than 8%. Therefore, the model and algorithm can assist the decision-makers to process road network repair schedule in post-earthquake.

Key words: earthquake disaster, emergency management, dynamic traffic flow, road network repair schedule
