A Study On Resource Satellite Image Product Demand Forecasting Model Based On Combined Method

As the continuous development of the aviation technology, Earth Resource Satellite Image has been applied into more and more fields such as environment prediction, climate prediction, and disaster prediction. This thesis studies the demand forecasting of Earth Resource Satellite Image in order to promote its development and achieve better economic effects. This thesis studies the correlation of total demand for repeat purchases and the accumulated users, describes the changing of the users diffusion and its mechanism and uses examples to testify the conclusion. The research has important theoretical and practical significance. .Firstly, gives a brief introduction to the background, status quo and the framework of this thesis. Secondly, talks about the characteristics of Earth Resources Satellite Images and its demanding situation; devises the demangding model and its compounding forms; gives a total description of the study method. In the main part of this thesis, a Bass model is brought forward to analyze the predicting process of the user numbers and repeated purchases, discusses their correlations, and uses the diffusion model to describe user diffusion. At last, known data are used to testify the established models; suggestions for future studies are proposed after comparing the forecasting results.This thesis focus on the demanding forecast of Earth Resource Satellite Image, expounds its classification, influence factors and the correlation with the user number. Bass model is used to describe the mechanism, which provides references in user diffusion and Earth Resource Satellite Image forecast for future research.
