Optimization Research On Our Country's Imports Iron Ore Logistics System

As the world's largest steel producer and consumer countries, to ensure a stable supply of raw materials and continuous steel channels, in particular the supply of ferrous raw materials for the healthy development of China's iron and steel industry is particularly important.Since regarding to the import iron ore this kind of batch very big primary raw material product, many years our country's iron and steel enterprise has been used the self-management way to carry on its thing to flow, also carries on the order, the transportation respectively, stores in the storehouse, transfers and so on the process, some enterprises even have the bulk cargo ships, to manage the marine transportation section transportation voluntarily. At the same time, the traditional import ore transportation, all is undertaken to transport the artificial center by the marine transportation, only is responsible for the port to the port transportation, to before and after each link does not need to care about. In the cargo circulation process such as the declaration, declares for examination, the memory, loading and unloading, the cargo connects with and so on the link, all artificial has wasted many time, the energy and the money.Firstly, the article analyzes the status of our country's transport ore imports through import ore flow to our country's characteristics, transportation and logistics flow research organization, makes our country's existing import ore transport problems.Secondly, the article analyzes the impact of import ore logistics relevant factors, to study our country's imported ore logistics needs, and uses linear regression, the index smooth and grey sequence GM (1,1) the three forecasting methods for our country's import of ores logistics conducted forecasts for 2006-2015.Thirdly, the article proposes our country's import ore delivery system optimized programmer and its specific optimization models and optimization process, according to China's imports of ores logistics system statuscharacteristics, the study of our country's import ore distribution center layout, scale and management, the establishment of the country's import ore delivery system optimization models introduced to the port as a starting point, building to grasp the overall situation and grasp the import of iron ore sparse port situation, steel enterprises and coordination of railways, highways, information communication port logistics distribution center for our imports of ore delivery system optimization programmer.Fourthly, the article achieves the model calculations and examples of the results of analysis. This article in full consideration import all quarters benefit under the iron ore supplier and iron and steel enterprise premise and so on, allocates and dispatches the thing to flow the total expense most to be small as a goal, bases on the model adopted for the identification of relevant parameters and carries on the solution, thus formulates the most superior thing to exile to a far away place delivers the strategy.
