地震应急救援队伍派遣及道路重建联合规划模型

摘要

In order to solve the problem of dispatch of emergency rescue teams and road reconstruction under earthquake disaster,considering the uncertainty of dispatch time under roads damaged and the demand of emergency rescue teams,a united programming model which took the constraints of rescue teams,rescue time and survival probability into account was built to maximize the survival probability of trapped people and the effect of the rescue task.To solve this model,the linear weighted method was proposed based on the characteristic of the multi-objective programming model.In addition,a numerical example was given to verify the effectiveness of the model and its solution.The results show that compared with the original schemes,the optimal dispatch scheme of emergency rescue teams generated by the proposed method can improve the rescue efficiency by 75％,and the optimal scheme of road reconstruction can save 89％ rescue resources.%针对地震灾害应急救援队伍的派遣及道路重建问题,在考虑灾区道路损毁情况对派遣时间影响及受灾点应急救援队伍需求量不确定性的基础上,建立了灾后应急救援队伍派遣及道路重建的联合规划模型.该模型以受困人员生存概率最大和应急救援队伍完成救援任务效果最佳为目标,考虑了救援队伍、救援时间和生存概率等约束因素,根据多目标规划模型的特点,给出了基于线性加权法的求解方法,数值算例验证了模型及其求解方法的有效性.研究结果表明:与原派遣方案相比,地震应急救援队伍的最优派遣方案提高了75％的救援效率;道路重建的最优方案节省了89％的救援资源.
