【摘要】 考虑灾后抢修失效路段对路网连通性的影响,以最大化应急资源配送效益为目标,基于资源-时延转换的思路,引入时延的随机性,构建了路网、路径联合优化模型。基于模型整体框架,设计了改进的遗传算法用于求解问题。算例分析展现了模型的实际应用过程和求解算法的有效性。更多还原

【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.更多还原
