面向公平分配的时变应急服务覆盖优化
|
Abstract:
应急服务需要根据实际情况在城市的某些区位中提前布置，才能保证需求发生时能在规定时间内到达需求位置，提供应急服务。布置区位时，需要根据时变交通条件的变化，适当考虑时空的合理分布，以为城市居民提供较为公平的服务覆盖。传统最大区位覆盖模型较少考虑服务的公平分配，特别是在时变交通和复杂大规模路网条件下，缺乏对公平量度的显式建模。基于目前区域覆盖优化模型的最近进展，扩展了传统最大区位覆盖模型，建立面向公平分配的时变应急服务覆盖模型，提出了相应的启发式高效求解方法。利用武汉市数据进行实验验证，证实模型求解得到的区位配置解较之传统模型，不仅提供了更加公平的应急服务覆盖，也考虑到了时变交通条件，改善了应急资源在时空上的均衡配置水平，整体上提高了应急服务质量
