By the combination of triple exponential smoothing prediction technique and grey prediction technique,the writer makes up the forecasting model of container throughput in Shanghai Port and forecasts the container throughput of 2000-2001 years.

The qualitative analysis on the basis of policy, experience prediction on the basis of the former investigation of environment protection industry and the prediction of the second smooth index are used to predict the total investment of environment protection and the technology equipment market capacity in the next five years.

Application of cubic exponential smoothing method to city underground deformation prediction;

In this paper,the exponential smoothing method and the prediction process of the cubic exponential smoothing method are introduced in detail.

<Abstrcat> Based on the freight volume data of Da-qin railway between 1989 and 2003, quantitative estimation and speculation of the development foreground, scale and level of Da-qin railway are given in the paper with the cubic exponential smoothing method.

According to the non-linear increasing characteristics of the container throughput of port, triple exponential smoothing forecasting model, grey system forecasting model and BP artificial neural network forecasting model are established respectively.

Meanwhile,it also analyzes the price trend according to grey-system theory GM(1,1) and smooth model SM2.
