Method, device and program for predicting sales number of merchandise, determination method of quantity, device and program

摘要

Problem to be solved: to provide a method of predicting the number of sales of a product, an apparatus and a program, an order of determining an order, an apparatus and a program, which are low in computational cost and low in computational cost.A sales number prediction method isParameter data comprising state variable 104 and external variable 105 and on line Gauss process parameter 106 andPast sales volumeWeatherA filtering step 107 for updating the state variable 104 and the external variable 105 and the on-line Gauss process parameter 106 to the latest state using the past performance data 101 comprising price, etc., andFuture state variables 111 and external variables 112 are updated using updated state variables 104 and external variables 105 and parameter data 106, and future condition data 108, including weather and priceA prediction step 113 for obtaining a sales quantity prediction value 114 and.Diagram
