为有效配置应急车辆资源、减少响应时间,在统一考虑规划阶段的车辆布局和运行阶段的车辆动态配置的基础上,提出一个面向城市应急车辆配置的决策支持系统。该系统集合P-Median,r-interdiction Median与Hypercube等相关配置模型,设计应急车辆选址、关键应急车辆辨识、应急车辆动态配置以及应急车辆工作情况评价4个模块,利用Visual C#.NET编程语言与ArcGIS Engine组件,实现模型的算法设计与优化结果的GIS显示。并以设计新疆自治区某市城区消防车辆的配置方案为例,测试该系统。在系统设计的方案中,3个站点工作负荷分别为0.46,0.4和0.52,跨区响应频率分别为0.16,0.35和0.32。仿真结果表明:配置方案的运行指标良好,选址与工作分配比较合理,系统达到测试要求。
In order to effectively allocate the resources of emergency vehicles and reduce the response time, a decision support system for city emergency vehicles configuration is proposed based on the unified vehicle layout during the planning phase and the dynamic configuration of vehicles during the operation phase. The system integrates P-Median, r-interdiction Median and Hypercube and other related configuration models, designs four modules of emergency vehicle location, key emergency vehicle identification, emergency vehicle dynamic configuration and emergency vehicle operation evaluation. Visual C # .NET programming language And ArcGIS Engine components, to achieve the model of the algorithm design and optimization results of the GIS display. And to design a city in Xinjiang Autonomous Region fire vehicles configuration program, for example, test the system. In the scheme of system design, the workloads of three sites are respectively 0.46, 0.4 and 0.52, and the cross-zone response frequencies are 0.16, 0.35 and 0.32 respectively. The simulation results show that the operating plan of the configuration scheme is good, the location and work distribution are reasonable, and the system meets the test requirements.
