| 摘 要： | 为提高突发公共事件应急系统的运行绩效，针对应急出救点选择及救援车辆路径的集成优化问题，考虑应急资源需求的模糊性和时间窗限制，以及救援车辆行驶时间的随机性，以各资源需求点的应急资源运达时间之和系统总成本最小为目标，建立一个不确定多目标机会约束规划模型，并设计一种遗传算法。最后，通过算例分析验证该模型和算法的有效性。 |

| Abstract： | To enhance the operation efficiency of emergency systems for public emergency, the integrated optimization of emergency service facility selection and vehicle routing problem is studied by considering the fuzzy demand of relief resources, time window constraints and stochastic travel time of emergency vehicles. An uncertain multi-objective chance-constrained programming model is developed to minimize the sum of arrival time of relief resources to all affected sites and the total system cost. And a genetic algorithm is proposed to solve the model. Finally, the validity of the model and algorithm is demonstrated by a numerical example. |
