【摘要】：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。
[Abstract]:Emergency services need to be arranged in advance in some urban areas according to the actual situation in order to ensure that the demand can reach the demand position in a specified time and provide emergency services. When the location is arranged, it is necessary to consider the reasonable distribution of time and space according to the change of time-varying traffic conditions, so as to provide fair service coverage for urban residents. The traditional maximum location coverage model seldom considers the fair distribution of services, especially under the condition of time-varying traffic and complex large-scale road network, and lacks explicit modeling of equity measurement. Based on the recent development of the regional coverage optimization model, the traditional maximum location coverage model is extended, and the time-varying emergency service coverage model for fair distribution is established, and the corresponding heuristic and efficient solution method is proposed. By using Wuhan data to verify, it is proved that the location allocation solution obtained by the model not only provides a fairer coverage of emergency services, but also takes into account the time-varying traffic conditions, compared with the traditional model. It improves the balanced allocation level of emergency resources in time and space, and improves the quality of emergency services as a whole.
