Problems solved by technology

[0004] However, most of the existing forecasting technologies face the following problems: 1. The forecasting technology is not universal enough, and most forecasting tools are designed for a specific field to select forecasting impact factors and design forecasting models
The prediction tools developed in this way are difficult to apply to other fields, and repeated development is also a waste of resources
2. Relying too much on data integrity when making forecasts
In many practical applications, customers cannot provide the data required for complete prediction, so it is impossible to train a high-precision prediction model

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 present invention provides a method and device for predicting a forecasted object, the method comprising: acquiring multiple historical data values ​​of the forecasted object within a predetermined historical period; looking for multiple influencing factors related to the forecasted object from the database, And obtain one or more data sources and predetermined algorithms corresponding to each impact factor; search the text information of each impact factor from one or more data sources, and convert the text information into multiple structured data according to the predetermined algorithm; According to multiple historical data values ​​and multiple structured data, the correlation coefficient between each impact factor and the forecast object is obtained, and part of the impact factors whose correlation coefficient meets the predetermined condition is taken out from multiple impact factors; according to multiple historical data values, it is calculated The length of the forecast period immediately after the predetermined historical period, and calculate the respective weights for some of the impact factors; according to the length of the forecast period and their respective weights, multiple forecast data values ​​of the forecast object within the forecast period are obtained.

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....
