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.
