1、精品名师归纳总结交巡警服务平台的设置与调度摘要警察肩负着刑事执法、治安治理、交通治理、服务群众四大职能,交巡警服务平台的设置与调度直接关系着上述职能的实现.本文主要争论城市中交巡警服务平台设置和详细调度问题,在确定各平台管辖范畴和增加平台位置置、数量等相关问题时,通过对已知条件中点的坐标和相应道路信息,对已知条件进行合理分析,从而进一步得出合理的平台设置和详细调度方案 .针对问题一:1.1 结合附件所给程序以及“路口到管辖其的交巡警服务台距离最短”的原就,来划分交巡警服务台的管辖区域,我们利用Floyd 算法求出任意两个路口的最短距离,在此基础上给出了 A 区各交巡警服务台的管辖范畴,发觉各服

2、务台的工作量安排不均衡,为此我们建立0-1 规划模型,利用 LINGO 软件求出各平台的管辖范畴(见表1) .1.2 这是一个关于发生重大突发大事时警力的调度问题,通过建模为13 个路口安排平台, 目标是使得封锁时间最小化,建立0-1 目标规划,运用 LINGO 软件编程,从而得到1.3针对问题二:2.12.2关键词:一、问题背景及重述1.1 问题背景可编辑资料 - - - 欢迎下载精品名师归纳总结“有困难找警察 ”,是家喻户晓的一句流行语.警察肩负着刑事执法、治安治理、交通治理、服务群众四大职能.为了更有效的贯彻实施这些职能,需要在市区的一些交通要道和重要部位设置交巡警服务平台.每个交巡警服

3、务平台的职能和警力配备基本相同.由于警务资源是有限的,如何依据城市的实际情形与需求合理的设置交巡警服务平台、安排各平台的管辖范畴、调度警务资源是警务部门面临的一个实际课题.1.2 问题重述试就某市设置交巡警服务平台的相关情形,建立数学模型分析争论下面的问题:( 1)附件 1 中的附图 1 给出了该市中心城区A 的交通网络和现有的20 个交巡警服务平台的设置情形示意图,相关的数据信息见附件2.请为各交巡警服务平台安排管辖范畴, 使其在所管辖的范畴内显现突发大事时,尽量能在3 分钟内有交巡警(警车的时速为60km/h )到达事发的 .对于重大突发大事,需要调度全区20 个交巡警服务平台的警力资源,

4、对进出该区的13 条交通要道实现快速全封锁.实际中一个平台的警力最多封锁一个路口,请给出该区交巡警服务平台警力合理的调度方案.依据现有交巡警服务平台的工作量不均衡和有些的方出警时间过长的实际情形,拟在该区内再增加2 至 5 个平台,请确定需要增加平台的详细个数和位置.( 2)针对全市(主城六区A ,B, C, D,E, F)的详细情形,依据设置交巡警服务平台的原就和任务,分析争论该市现有交巡警服务平台设置方案(参见附件)的合理性.假如有明显不合理,请给出解决方案.假如该市的点 P(第 32 个节点)处发生了重大刑事案件,在案发3 分钟后接到报警, 犯罪嫌疑人已驾车逃跑.为了快速搜捕嫌疑犯,请给

5、出调度全市交巡警服务平台警力资源的正确围堵方案 .二、问题分析问题一:1.1 此题主要解决A 区交巡警服务平台的管辖范畴,主要考虑出警的最短时间问题(即最短距离问题)与每个平台的发案率两因素.这里运用0-1 规划模型,采纳Floyd 算法求出两个节点间的最短距离,再依据所建立的模型划分出各平台的管辖范畴.1.21.3问题二:2.12.2三、模型假设1、两相邻路口间车辆同向行驶,假设在此路段上不发生事故,事故只会发生在路口的节点处。2、假设每一个交巡警服务平台接到报警时,能立马前去支援。3、假设犯罪嫌疑人逃亡速度与警车速度相同.四、符号说明i : 第i个节点。j : 第j 个交巡警服务平台。可编
