With the development of Internet and big data, more consumer behavior data are used in different forecasting problems, which greatly improve performance prediction. As main travel tool, sales automobiles will change with variations market external environment. Accurate prediction automobile can not only help dealers adjust their marketing plans dynamically but also economy transportation sector make policy decisions. The is a product high value involvement, its purchase decision be affected by own attributes, economy, other factors. Furthermore, sample have characteristics various sources, great complexity large volatility. Therefore, this paper uses Support Vector Regression (SVR) model, has global optimization, simple structure, strong generalization abilities suitable for multi-dimensional, small to predict monthly automobiles. In addition, parameters optimized Grey Wolf Optimizer (GWO) algorithm accuracy. First, grey correlation analysis method analyze determine factors that affect sales. Second, it build GWO-SVR model. Third, experimental carried out using from Suteng Kaluola Chinese car segment, proposed model compared four commonly methods. results show best mean absolute percentage error (MAPE) root square (RMSE). Finally, some management implications put forward reference.

The study compares the forecasting performance of grey type models, represented by an optimized nonlinear Bernoulli model (ONGBM), a with particle swarm optimization (NGBM-PSO), and standard GM classic time series model, Auto-Regressive Integrated Moving Average (ARIMA). models are compared based on simulations energy consumption in Brazil India at aggregate disaggregate levels from 1992 to 2019. illustrates picture nexus disaggregated levels. accuracy is using measures such as MAPE, MSE, RMSE, normalized RMSE. Diebold-Mariano test findings validates ARIMA (1,1,1), (1,1), ONGBM (1,1) NGBM (1,1)-PSO models' equal predictive performance. used compute forecast combinations, ensuring smaller errors than single models. Optimizing two algorithms ensures highest efficiency for short series. results allow recommendation use short-term combine these forecasts (1,1,1) practical applications.
