【摘要】 随着区域同城化,交通一体化的不断发展,人们享受其带来巨大好处的同时,也正在承受其带来的负面影响。突发事件以其突发性、破坏性、不可预测性,给人民的生命财产安全造成严重损失。近年来突发事件的发生呈现跨区域、高频率特征,影响着社会稳定和经济发展大格局,为区域协调发展带来一大挑战。面对影响极其恶劣的突发事件,需要大量的应急物资,进行生命救助、生活保障、联防联控、恢复秩序等工作,才能做到对突发事件的有效控制。目前跨区域救援研究大多数停留在概念提出阶段,本文在总结既有研究现状的基础上,提出跨区域综合交通运输网应急救援基础理论,研究救援需求等级,设计跨区域条件下应急物资的调度方案包括运输工具选择、运送数量、分发方案等详细内容。围绕本文的研究目的,具体研究开展如下:(1)研究跨区域综合交通运输网救援基础理论。首先对跨区域综合交通运输网救援的相关基础概念进行界定,确定研究范围;然后分析跨区域综合交通运输网救援的要素、救援网络特征,对跨区域综合交通运输网救援进行综合分析,包括跨区域救援的条件、制约因素、解决的关键问题以及跨区域救援的运作流程,为核心研究奠定基础。(2)研究跨区域综合交通运输网应急调度理论。总结既有研究与实际调研,分析跨区域救援紧迫性影响因素,设计了基于TOPSIS方法的救援需求等级研究模型,确定各受灾点的救援优先级。在应急物资调度研究中,先对抽象的综合交通运输网进行分析,使得调度过程步骤化、清晰化。详细分析影响调度过程的相关因素,构建多目标多约束的跨区域综合交通运输网应急调度模型,采用改进粒子群算法进行求解。(3)紧跟时事,联系国情。本文对当下正在用举全国之力克服的新冠肺炎为背景做算例研究,致敬正在前线指挥作战的领导、医务人员以及所有抗疫相关的工作人员。通过分析湖北各市(区)的疫情情况,做救援需求等级分析,最后设计跨区域综合交通运输网应急调度算例,验证理论的合理性与有效性。通过本文研究,形成一套系统的跨区域综合交通运输网救援理论,为跨区域物资调度提供决策依据,这是对跨区域应急管理合作研究较好的理论补充,对资源共享与区域协调发展具有重大意义。更多还原

【Abstract】 With development of regional urbanization and the integration of transportation,people are enjoying the huge benefits while also suffering the negative impacts.Due to the suddenness,destructiveness and unpredictability of emergency on transportation,emergencies lead to great losses of people’s lives and property.In recent years,emergencies show characteristics of trans-regional and high-frequency.Cases of emergency has affected social stability and economic pattern,and brought a major challenge to the development of region coordination.Thus,when an unexpected emergency arises,we are facing many difficulties in materials allocation for life rescuing,emergencies relief,reinstating order.By now,most researches just proposed the concept of trans-regional rescue,without further detailed proposals.Based on the summary of current researches,this paper proposes a theory of trans-regional emergency rescue on integrated transportation network,demonstrates the urgency levels of rescue demands.Besides,this paper designs schemes for emergency materials dispatching,which includes the utilization,quantity,and plan for transportation modes,respectively.The main contribution of this paper is shown as follows:(1)Investigated the basic theory of trans-regional on integrated transportation networks to lay the foundation for core research.First,determined the scope of research based on relative concept of emergency rescue.Second,analyzed the fundamental elements of trans-regional rescue on comprehensive transportation network,and analyzed its characteristics.Third,comprehensively analyzed trans-regional rescue about conditions,constraints,main solved issues and operation procedure.(2)Studied the theory of inter-regional emergency dispatching on integrated transportation network.Summarized existing researches,analyzed the urgency influencing factors of trans-regional rescue,and designed a rescue demand level model based on improved TOPSIS method to determine the rescue demand priority of each disaster site.About emergency material dispatching,first analyzed the comprehensive transportation rescue network to make the dispatching process step-by-step and clear.Analyzed the relevant factors that affect the dispatching process in detail,constructed a multi-objective and multi-constraint model for trans-region emergency dispatching on integrated transportation network,and solved it with an improved particle swarm algorithm.(3)This paper is meaningful to current events and national conditions.A case study is conducted based on covid-19 in Wuhan,which is overcome by the whole country,and show much respect for the leaders,medical staff and all staff involved in combating the epidemic.By analyzing the epidemic situation in Hubei cities(districts),analyzed the urgency of rescue needs,and finally designed an emergency dispatching case of trans-regional integrated transportation network.The rationality and effectiveness of proposed theory is verified.Through this paper,a set of systematic trans-regional rescue theory on comprehensive transportation network is formed,which provides a basis for decision-making for trans-regional material dispatching.This is a good supplement on theory of trans-regional emergency management cooperation,and it is significant for resource sharing and regional coordination development.更多还原
