The Analysis Of The Outputs Of Steel And Nonferrous Metal Basing On Time Series

The mineral resources belong to non-renewable resources, which will be exhausted by making use of. And, the mineral resource is an important strategic resources. It's necessary to give the mineral resource intensive management. Therefore, it's vital to forecast the output of the mineral resources. This paper, with the method of time series analysis, explores, from the development's internal cause angle, the inherent laws of steel products output as well as the non-ferrous metal output of our country. This article uses the traditional time series analysis method to unfold the characteristic of steel products output as well as the non-ferrous metal output of our country. And establishes the linear model, witch is used to forecast the long-term trend of the steel products output as well as the non-ferrous metal output. The establishment of the Auto-regressive Moving Model (the ARMA model) is used to give short-term ,exact prediction of the steel products output as well as the non-ferrous metal output .
