| 摘 要： | 为了解决高速公路网多救援点出救,多种类、多数量救援车辆处置多起交通事故问题,应用agent方法建立了救援车辆动态派遣模型.模型将事故作为任务agent,救援车辆作为资源a-gent,将任务延时损失最小和派遣资源成本最少作为系统性能指标.针对多agent协作性特点及多起事故救援的不确定性,设计了招投标过程,并在积累救援信息、寻求多目标最优解过程中,制定了agent启发式学习过程,获得动态最优解.南京市周边高速公路网救援实例表明,基于agent的救援车辆派遣方法可以动态地获得全局优化的派遣决策方案,验证了方法的可行性和有效性.

| Abstract: | In order to solve the multi-accident handling problem with multi-depot,multi-variety and many rescue vehicles over the expressway network,the agent-based method is used to establish the dynamic dispatch model for rescue vehicles.Each accident is considered as a task agent and each kind of rescue vehicle is viewed as a resource agent.The system performance indexes are to minimize the delay losses of the task and the costs of dispatching the resources from depots.According to the cooperation characteristic of... |
