Automobile Sales Forecasting Model

In the process of economic development, the automotive industry has an important position. In recent years, China's automobile sales with the development of auto parts sales are high-speed development, and sales have been expanding. With the development of information technology, collection of vehicle sales growing wealth of historical data, sales forecast information becomes more prominent. Car dealers need to forecast automobile sales, making future sales plan to ensure a reasonable inventory, parts sales, to meet user demand for automobile sales. Therefore, how to use a more accurate model of vehicle sales forecasts, historical sales data was found hidden in vehicle sales laws, this is a very necessary study.This paper aims to establish a flexible and efficient automobile sales forecasting model, so as to realize the accurate prediction of vehicle sales. In this paper, the popular ERP business management analysis, sales forecasting model and some other comparison, with a focus on some popular now auto industry forecasting methods and a single, hybrid prediction model study. Linear prediction model and nonlinear prediction models, quantitative and qualitative forecasting methods forecasting methods combining prediction model, and using historical data analysis and testing, so as to establish the final prediction model for automobile sales.This article is from the history of automobile sales data of sales to start, build forecasts by the moving average method, exponential smoothing forecasting method and regression analysis forecasting for portfolio allocation by weight combination forecasting model, combined with RBF neural network model integrated forecast model. Combination forecasting model focuses on the weight distribution on this basis, a detailed study of the application of integrated prediction model. In the study, the computer technology, mathematical economics, statistical techniques and technology used in automobile sales forecasting model, which will improve the model of a unity problem areas. Comprehensive prediction model improves on the period of time after the automobile sales forecast accuracy, expand vehicle sales forecast model in practical car sales forecast range.
