Abstract
Since domestic iron ore resources are wide, poor and of lower grade, the steel
industry relies on imported iron ore more than ever when steel output in China reached
300 million tons a year. Current logistics management methods and tools, which are far
from systemic and advanced, cannot adapt to the changing environment of iron ore
logistics effectively and are facing the pressure to ensure production and lower the
purchase costs. In this case, optimize the logistics system of imported iron ore in Wuhan
Iron and Steel (Group) Corporation (WISCO), which is ranked 3rd in China, by modern
theory and technology to reduce the costs, petitiveness of domestic iron and
steel enterprises is of great significance.
By analyzing problems and difficulties about the logistics system of imported iron
ore in WISCO, this paper researches on actual situation using quantitative solutions, to
improve service capability and reduce costs of logistics system. First of all, current
situation of domestic logistics management, especially in the steel industry is briefed as
well as the circumstance of WISCO. Secondly, current researches of time series analysis
and location-allocation problem are introduced with a specific introduction of logistics
costs forecasting in ocean shipping. With specific logistic
