Problems solved by technology

[0008] However, there is a problem that the economic index data of the designated period shifted from the reference period by a predetermined time tends to cause errors from the economic fluctuations in the reference period and the demand generation time of parts, and it is impossible to accurately predict the demand for products.

Embodiment approach 1

[0023] figure 1 It is a block diagram showing the configuration of the demand forecasting device 1 according to the first embodiment. Demand forecasting device 1 is a device for forecasting product demand, such as figure 1 As shown, it includes a time series data input unit 11 , a time series data storage unit 12 , a forecast model storage unit 13 , an analysis unit 14 , a forecast model selection unit 15 and a forecast result output unit 16 . Hereinafter, the product to be subjected to the demand forecast is simply referred to as "product".

[0024] The time-series data input unit 11 is an input unit that accepts input of time-series data. The time-series data storage unit 12 is a storage unit that stores time-series data received by the time-series data input unit 11 . Time-series data includes actual performance data, which is a time-series obtained by sequentially observing actual performance values ​​of product demand over time, and time-series obtained by sequentially...

Embodiment approach 2

[0065] Figure 5 It is a block diagram showing the configuration of a demand forecasting device 1A according to Embodiment 2. exist Figure 5 in, for figure 1 The same structural elements are denoted by the same reference numerals and explanations thereof are omitted. The demand forecasting device 1A includes a time-series data input unit 11 , a time-series data storage unit 12 , a forecast model storage unit 13 , an analysis unit 14A, a forecast model selection unit 15A, and a forecast result output unit 16 .

[0066] The analysis unit 14A processes the waveform of the actual performance data and the waveform of the related data, analyzes the waveform-processed actual performance data and related data, and thereby selects the second actual performance data and the second related data used for product demand forecasting. The analysis unit 14A includes a similarity analysis unit 141 , a data selection unit 142 , a waveform adjustment unit 143 , and a waveform processing unit...

Abstract

A demand prediction device (1) processes first associated data so as to resemble first performance data, selects data resembling the processed first associated data from among second performance data and second associated data, adjusts the waveform of the second associated data so as to match a trend of the selected second performance data, and selects a prediction model in accordance with the trend of the second performance data, thereby predicting demand.

Description

technical field [0001] The invention relates to a demand forecasting device and a demand forecasting method. Background technique [0002] For example, the demand forecasting device described in Patent Document 1 predicts demand for components using a multivariate analytical model. The multivariate analytical model uses the actual number of parts delivered as a solution, the number of devices in operation having the parts as a factor, the operating time of the device as a factor, and an economic index for a specified period as a factor. The economic index is an economic index related to the demand for components, for example, a business trend index, an average stock price, or a fuel price. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2015-118412 Contents of the invention [0006] The problem to be solved by the invention [0007] In the demand forecasting device described in Patent Document 1, in ord...
