Study on Pre-estimating Sale Volume of Petroleum Products in Gas Station Based on Time Sequence

It is an important measure for improving the level of controlling the stock of petroleum products in a gas station by conducting a precise pre-estimation of the sale volume of the petroleum products in the gas station. This paper provides a variable weight combined model for conducting reasonable pre-estimation of the sale volume of the petroleum products in a gas station. Empirical simulation proves that this model is better than those simple pre-estimation methods both in sample and out of sample, indicating that this variable weight combined model is a petroleum product sale volume pre-estimation model that has higher precision and certain practical value.
