Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the embodiments.

[0041] figure 1 is a flowchart showing a method for predicting a prediction object according to an embodiment of the present invention. In step S11, a plurality of historical data values ​​of the predicted object within a predetermined historical period are acquired. The prediction objects are, for example, tire sales volume, crude oil sales volume, etc. In this embodiment, only the tire sales volume is used as the prediction object for illustration. The predetermined historical period is, for example, from January 2014 to December 2014, and the acquired multiple historical data values ​​are shown in Table 1.

[0042] Table 1

[0043]

[0044] Next, in step S12, a plurality of influencing factors related to tire sales are searched from the database, and one or more data sources corresponding to each influencing factor in the plurality of influencing factors and a predete...

Abstract

The invention provides a method and a device for carrying out prediction on a predicted object. The method comprises the steps of acquiring a plurality of historical data values of the predicted object in a predetermined historical period; searching a plurality of influence factors related with the predicted object from a database, and acquiring one or more data sources corresponding to each influence factor and a predetermined algorithm; searching text information of each influence factor from the one or more data sources, and converting the text information into a plurality of pieces of structured data according to the predetermined algorithm; acquiring a correlation coefficient of each influence factor and the predicted object according to the plurality of historical data values and the plurality of pieces of structured data, and taking out part of the influence factors whose correlation coefficients meet a predetermined condition from the plurality of influence factors; acquiring the length of a prediction period which is immediately after the predetermined historical period according to the plurality of historical data values, and calculating the weights of part of the influence factors respectively; and acquiring a plurality of prediction data values of the predicted object in the prediction period according to the length of the prediction period and the respective weights.

Description

technical field [0001] The present invention relates to a method and device for forecasting general demand, in particular to a method and device for forecasting objects. Background technique [0002] With the continuous expansion of the scale of modern production and sales, how to make a reasonable production plan has become a major issue that affects the cost and profit of the enterprise. Many companies do not have an effective method to predict future market demand, or the backlog of excess products in the warehouse has brought great pressure to the capital chain, or the supply of products must not miss the effective opportunity to occupy the market. These possible results will seriously affect the operating efficiency of the enterprise and affect the long-term development of the enterprise. [0003] As an important part of the field of artificial intelligence, demand forecasting technology has been studied for many years, and many related technologies have been proposed....
