| Abstract: | The impact to roadway network derived from repairing damaged roadway after catastrophe is discussed.From the view of delay-resource conversion,for maximizing the benefit of emergency relief distribution,combining the road network and vehicle routing,considering stochastic travel time,a combinatorial optimization model is developed.An improved genetic algorithm is designed to solve this problem.As a demonstration,a numerical example is presented to highlight the significance of the proposed model as well as the efficacy of the improved algorithm. |
