【摘要】：煤炭作為一種國家戰(zhàn)略性的能源,在我國應(yīng)用相當(dāng)廣泛。隨著近年來,煤炭行業(yè)逐漸進(jìn)入低谷期,整個行業(yè)面臨著調(diào)整與革新。在經(jīng)濟(jì)高速發(fā)展時被掩蓋的一些粗放發(fā)展的弊病逐漸顯現(xiàn),如物流規(guī)劃不合理導(dǎo)致的高運(yùn)價,地方保護(hù)主義導(dǎo)致的運(yùn)輸距離延長,各種煤礦點選址的不合理等等。各種問題都表明,在當(dāng)前形勢下高效率的運(yùn)用煤炭資源顯得尤為重要。作為一種低附加值的產(chǎn)品,煤炭運(yùn)輸在整個煤炭開發(fā)利用中占有舉足輕重的地位。因此,規(guī)劃高效率低成本的煤炭運(yùn)輸網(wǎng)絡(luò)既是煤炭產(chǎn)業(yè)發(fā)展的重點也是其健康高效造福社會的必要條件。對于物流節(jié)點選址問題的研究一直是物流領(lǐng)域及學(xué)術(shù)界研究的重點,本文將在以有的研究成果上做出適當(dāng)?shù)恼{(diào)整和創(chuàng)新。在文章開始,本文分別從所研究的背景、研究的必要性、研究的內(nèi)容和方法以及國內(nèi)外研究情況四方面入手,對文章主題進(jìn)行較為詳細(xì)的背景介紹和宏觀把握。包括我國整體的能源格局和分布開發(fā)情況,我國煤炭物流運(yùn)輸目前存在的一些問題,以及將要運(yùn)用的關(guān)于節(jié)點選址、路徑優(yōu)化的相關(guān)方法介紹。隨后,本文對論文中涉及到的相關(guān)理論做簡要陳述,對目前國內(nèi)外學(xué)術(shù)界的相關(guān)研究方法做出簡要羅列。在此基礎(chǔ)上,本文分別從煤炭生產(chǎn)點的選址、中斷情形下的物流中心點的選址及整個系統(tǒng)的路徑優(yōu)化三方面展開對山西省煤炭物流課題的研究。在煤礦生產(chǎn)點選址方面,本文主要以Arcgis地里信息系統(tǒng)軟件為工具,山西省煤層分布情況為依據(jù),繪制出以山西省現(xiàn)有煤炭儲量為選址依據(jù)的煤礦生產(chǎn)點分布圖。并從中選出備選的煤礦生產(chǎn)點作為后文中斷情形下物流中心選址的依據(jù)；在物流中心選址方面,本文充分考慮了不確定性風(fēng)險發(fā)生的可能,嘗試著通過建立一種數(shù)學(xué)模型來模擬出一種可以最大限度的降低中斷風(fēng)險發(fā)生所帶來的成本增加的高魯棒性的供應(yīng)鏈體系,并且運(yùn)用拉格朗日松弛算法進(jìn)行求解；在物流通道優(yōu)化方面,本文著重考慮了在需求點需求不確定情形下的通道優(yōu)化問題,將優(yōu)化問題分為兩步：第一步是在特定的需求環(huán)境下,以最小成本為依據(jù)來決定最佳的路徑選擇計劃,第二步運(yùn)用建立好的數(shù)學(xué)模型來進(jìn)一步確定路徑選擇的種類(公路、鐵路)從而使整個物流網(wǎng)絡(luò)運(yùn)行效應(yīng)最大化。最后總結(jié)了本文的創(chuàng)新點和解決的具體問題,同時分別從變量的選取、數(shù)據(jù)的采集、模型的優(yōu)化等方面介紹了本文的不足和待改進(jìn)之處。
[Abstract]:As a kind of national strategic energy, coal is widely used in China. With the recent years, the coal industry has gradually entered a low period. The whole industry is faced with adjustment and innovation. In the rapid development of the economy, some problems of extensive development gradually appear, such as unreasonable logistics planning resulting in high freight rates, local protectionism caused by the extension of transport distance. All kinds of problems show that the efficient use of coal resources is particularly important in the current situation. As a low value-added product. Coal transportation plays an important role in the development and utilization of coal. Planning the coal transportation network with high efficiency and low cost is not only the focus of the coal industry development but also the necessary condition for its health and efficiency to benefit the society. The point. This paper will make appropriate adjustments and innovations on some research results. At the beginning of the article, this paper respectively from the background of the study, the necessity of research. The contents and methods of the research as well as the domestic and foreign research in four aspects, the article theme of a more detailed background and macro-grasp, including the overall energy pattern and distribution of development in China. Coal logistics transportation in China has some problems, as well as the use of node location, path optimization related to the introduction. Subsequently, this paper makes a brief description of the related theory involved in the paper. On the basis of a brief list of relevant research methods at home and abroad, this paper respectively from the coal production sites. The location of the logistics center and the path optimization of the whole system are studied in three aspects: the coal logistics project in Shanxi Province, and the location of the coal production site in the coal mine. This paper mainly takes the Arcgis field information system software as the tool, Shanxi Province coal seam distribution situation as the basis. The distribution map of coal production sites based on the existing coal reserves in Shanxi Province is drawn, and the alternative coal production sites are selected as the basis for the location of logistics center under the situation of later interruption. In the logistics center location, this paper fully considered the possibility of uncertainty risk. Try to establish a mathematical model to simulate a supply chain system with high robustness which can minimize the cost increase caused by interruption risk. And the Lagrangian relaxation algorithm is used to solve the problem. In the aspect of logistics channel optimization, this paper focuses on the channel optimization problem in the case of demand point demand uncertainty. The optimization problem is divided into two steps: the first step is in a specific demand environment. Based on the minimum cost to determine the best path selection plan, the second step to establish a good mathematical model to further determine the type of path choice (highway). Railway) so as to maximize the operation effect of the entire logistics network. Finally, this paper summarizes the innovation and specific problems solved, at the same time, from the selection of variables, data collection. The optimization of the model and other aspects of this paper and the shortcomings of the improvement.
