摘 要
鋼鐵企業對礦石需求量較大，對高品質的鐵礦石依賴性大，而且在目前的情況下國際鐵礦石價格持續高漲，以及運輸價格普遍上漲，需要加強對礦石採購的研究，實施有效的管理和控制。重鋼鐵礦石運輸主要依靠長江水路運輸，因此三峽單線執行給重鋼造成了很大的影響，在供應穩定性和運輸保障之間存在着矛盾更加凸出。爲此，企業佔用了大量的準備成本，並給企業礦石存儲造成極大的風險。從而本論文的研究就顯得更加具有現實意義。
本文將從影響運輸的多個環節展開論述，分析影響運輸的原因，設計多種可行方案，找出合理方案，運用特定的經濟預測模型和運籌學方法，從成本角度出發分析的實際問題，保證礦石供應的'穩定，優化礦石運輸路線，確定礦石的合理運輸量，解決了重鋼在三峽船閘單線執行期間礦石運輸量的問題，同時還可以爲其它的環節如煤炭運輸和其他的相關企業提供借鑑。
關鍵詞： 礦石採購，預測，三峽單線執行，運輸模式，運輸分流
Study on the plans of Emergency Transportation Of Iron ore for Chongqing Iron and Steel Company
ABSTRACT
Iron and steel enterprises have great demand for ores, largely dependent on high quality ores, moreover the international iron ore price continues to surge upward in the present situation, as well as universal transportation price are rising, need to strengthen research on the procurement of ore for implementing effective management and control. Chongqing Iron and Steel Company Ltd (CQISC Ltd) steel transport ore rely mainly on the Yangtze waterway transportation, the Three Gorges single routes movements caused a great deal of influence on CQISC Ltd stability in the supply and transportation , the existence contradiction will be more fierce. Therefore, the enterprise occupies the massive preparations costs, and the ore storage creates the enormous risk for the enterprise. Thus this paper appears has the even more practical significance.
This paper will affect many areas of transport exposition, analysis of the impact on the transportation, designs many kinds of feasible plans and discovers the reasonable plan, use specific economic forecast model and operations research, from the cost point of view of analysis of the actual problem, guarantee a stable supply of ores, ores transport route optimization to determine the reasonable transport ore volume, indeed resolving CQISC Ltd ore freight volume question in the Three Gorges sluice single routes movement period, meanwhile may provides the model for other partials like coal transportation and other similar enterprises.
