【摘要】：隨著我國城市化進(jìn)程的不斷推進(jìn)，城市的人口、財(cái)產(chǎn)以及地鐵、供水、供電等生命線工程越來越密集，一旦發(fā)生突發(fā)事件，將會嚴(yán)重?fù)p害人民的生命安全和財(cái)產(chǎn)安全。突發(fā)事件發(fā)生后，為了有效減少損失，提高應(yīng)急救援效率，如何科學(xué)合理的確定應(yīng)急物流系統(tǒng)中的應(yīng)急物流配送中心選址問題和規(guī)劃安排應(yīng)急救援物資運(yùn)輸路線問題成為災(zāi)后應(yīng)急救援應(yīng)解決的重要問題，也是當(dāng)前應(yīng)急物流研究的關(guān)鍵問題。針對此，本文從集成化角度對應(yīng)急物流定位-路徑問題進(jìn)行了一些研究。 本文以構(gòu)建突發(fā)事件下應(yīng)急救援的應(yīng)急物流定位-路徑問題模型為主線，分析了應(yīng)急物流和應(yīng)急物流定位-路徑問題的國內(nèi)外研究現(xiàn)狀以及當(dāng)前存在的問題，概括了應(yīng)急物流的特點(diǎn)、運(yùn)作流程以及應(yīng)急物流涉及的關(guān)鍵技術(shù)，突出了應(yīng)急物流有別于一般商業(yè)物流，并指出了影響實(shí)際應(yīng)急救援效率的關(guān)鍵因素之一是災(zāi)后物資的配送速度，同時(shí)，對應(yīng)急物流定位-路徑問題進(jìn)行了定義。 由于應(yīng)急物流定位-路徑問題模型的構(gòu)建涉及到應(yīng)急物流配送系統(tǒng)中所包含的各個(gè)環(huán)節(jié)，因此，本文重點(diǎn)分析了應(yīng)急物流配送網(wǎng)絡(luò)所涉及的各個(gè)關(guān)鍵因素，并重點(diǎn)分析應(yīng)急物流配送中心選址和應(yīng)急救援物資路線安排的影響因素，確定了構(gòu)建應(yīng)急物流定位-路徑問題模型的主要約束條件為信息約束、時(shí)間約束以及資源約束等。結(jié)合突發(fā)時(shí)間后應(yīng)急救援的實(shí)際目的，本文構(gòu)建的模型選取的是配送時(shí)間最短和救援成本最低雙目標(biāo)體系，并以配送時(shí)間最短為主要目標(biāo)。 在確定模型目標(biāo)、約束條件后，本文通過定量與定性相結(jié)合的方法，建立了應(yīng)急物流定位-路徑問題的數(shù)學(xué)模型，，模型中考慮到了突發(fā)事件后受災(zāi)區(qū)物資需求的模糊性和受災(zāi)區(qū)應(yīng)急救援的時(shí)間容忍度，并設(shè)計(jì)了雙目標(biāo)混合遺傳禁忌算法對模型進(jìn)行求解。最后，以深圳市為背景，模擬應(yīng)用了所構(gòu)建的模型和設(shè)計(jì)的算法，并分析了在應(yīng)用過程中出現(xiàn)的問題，提出了一些優(yōu)化應(yīng)急物流的建議。
[Abstract]:With the development of urbanization in China, urban population, property, subway, water supply, power supply and other lifeline projects are becoming more and more intensive. Once a sudden event occurs, it will seriously damage the safety of people's lives and property. In order to effectively reduce losses and improve the efficiency of emergency rescue, How to scientifically and reasonably determine the location of emergency logistics distribution center and arrange the transportation route of emergency relief materials in emergency logistics system becomes an important problem that should be solved in post-disaster emergency rescue. It is also the key problem in the research of emergency logistics. In view of this, this paper studies the location-path problem of emergency logistics from the angle of integration. Based on the construction of emergency logistics location-path problem model for emergency rescue, this paper analyzes the domestic and foreign research status and existing problems of emergency logistics and emergency logistics location-path problem. The characteristics of emergency logistics, operation process and key technologies involved in emergency logistics are summarized, and the difference between emergency logistics and general commercial logistics is highlighted. It is pointed out that one of the key factors affecting the efficiency of emergency rescue is the distribution speed of materials after the disaster. At the same time, the location-path problem of emergency logistics is defined. As the construction of the emergency logistics location-path problem model involves all the links in the emergency logistics distribution system, this paper focuses on the analysis of the key factors involved in the emergency logistics distribution network. The factors influencing the location of emergency logistics distribution center and the route arrangement of emergency relief materials are analyzed, and the main constraints of constructing the model are information constraint, time constraint and resource constraint. Combined with the practical purpose of emergency rescue after emergency, the model constructed in this paper selects the two-objective system of the shortest delivery time and the lowest rescue cost, and takes the shortest distribution time as the main target. After determining the objectives and constraints of the model, this paper establishes a mathematical model of the location-path problem of emergency logistics through the combination of quantitative and qualitative methods. The fuzziness of material demand and the time tolerance of emergency rescue are considered in the model, and a hybrid genetic Tabu algorithm is designed to solve the model. Finally, taking Shenzhen as the background, the model and the design algorithm are simulated and applied, and the problems in the application process are analyzed, and some suggestions for optimizing emergency logistics are put forward.
