【摘要】:伴隨我國城市化步伐不斷地邁進,城市化已成為我國發(fā)展的主旋律。然而,當城市規(guī)模不斷地擴大時,城市內(nèi)人口基數(shù)也在變大,當各類突發(fā)事件發(fā)生時,嚴重地影響到人民的生活、生產(chǎn)及生命財產(chǎn)安全。在交通線路密集的城市內(nèi),如何快速地實施救援,,應急救援車輛選徑就顯得尤為重要。在此背景下,研究城市突發(fā)事件應急救援車輛路徑選擇已成為當前城市突發(fā)事件應急救援的迫切需求。 對應急救援車輛路徑選擇的研究離不開對救援車輛的調(diào)配和路徑選擇的研究。如何在城市發(fā)生突發(fā)事件時高效地調(diào)配應急救援車輛并快速地到達事故突發(fā)點,是目前我國應急救援面臨的一道難題。本文根據(jù)我國城市突發(fā)事件應急救援的發(fā)展方向,分析了我國城市當前頻發(fā)生的突發(fā)事件基本類型,并進行了總結(jié),得出了城市突發(fā)事件易發(fā)類型的新趨向。通過對救援車輛調(diào)配及救援路徑選擇的研究,應用TransCAD對城市突發(fā)事件應急救援車輛路徑選擇進行仿真。論文的主要研究內(nèi)容如下: (1)通過對過去的城市突發(fā)事件類型的分析,總結(jié)出了當前城市突發(fā)事件的特點和易發(fā)生的突發(fā)事件類型。 (2)分析了基本的VRP及其擴展問題的相關(guān)模型和算法,得出了研究應急救援車輛路徑所需的要素。 (3)根據(jù)目前對城市突發(fā)事件應急救援中考慮因素的不足,對應急救援車輛選擇的路徑進行了可靠度分析,得出了城市應急救援車輛行程的風險函數(shù)和復雜函。 (4)通過對標準的VRP模型分析,提出了一種帶約束條件的多目標城市應急救援車輛路徑選擇模型。 (5)使用TransCAD軟件對提出的數(shù)學模型進行了仿真,并驗證了該模型的合理性。 (6)對實時條件下城市應急救援車輛選徑進行了分析,得出了在考慮時間優(yōu)先的情況下,應建立一個實時應急指揮系統(tǒng),對應急救援車輛選徑進行實時指揮。
[Abstract]:Along with the pace of urbanization in China, urbanization has become the main theme of the development of our country. However, when the scale of the city continues to expand, the population base of the city is also becoming larger, when all kinds of emergencies occur, It has a serious impact on people's life, production and safety of life and property. In cities with dense traffic lines, it is particularly important how to carry out rescue work quickly, and how to select the paths of emergency rescue vehicles. In this context, It has become an urgent need to study the vehicle route selection for emergency rescue of urban emergencies. The research on the route selection of emergency rescue vehicle is inseparable from the study of the allocation and route selection of the rescue vehicle. According to the development direction of emergency rescue in cities of our country, this paper analyzes the basic types of emergencies that occur frequently in cities of our country, and summarizes them. Through the research on the allocation of rescue vehicles and the choice of rescue path, the TransCAD is used to simulate the route selection of emergency rescue vehicles. The main research contents of this paper are as follows:. 1) by analyzing the types of urban emergencies in the past, this paper summarizes the characteristics of urban emergencies and the types of emergencies that are easy to happen. (2) the basic models and algorithms of VRP and its extended problem are analyzed, and the essential factors for studying the route of emergency rescue vehicle are obtained. 3) according to the deficiency of the factors considered in the emergency rescue of the city, the reliability analysis of the route chosen by the emergency rescue vehicle is carried out, and the risk function and complex letter of the travel of the emergency rescue vehicle in the city are obtained. 4) by analyzing the standard VRP model, a multi-objective urban emergency rescue vehicle routing model with constraints is proposed. 5) the proposed mathematical model is simulated with TransCAD software, and the rationality of the model is verified. This paper analyzes the route selection of urban emergency rescue vehicles under real-time condition, and concludes that a real-time emergency command system should be established under the consideration of time priority to conduct real-time command of emergency rescue vehicles.
