<p>PURPOSE:To obtain an accurate and minute estimated total amount of sales by setting plural estimated amounts of sales within a knowledge base together with the generating frequencies added to these estimated amounts for each condition of each sales factor. CONSTITUTION:A knowledge base 11 formed on a magnetic recording disk is provided together with an inference engine part 12 which actually carries out an inference, and a user interface device 13 which contains an inference condition input part 13a which inputs various conditions for the inference and an inference result output part 13b which displays and outputs the estimated total amount of sales for each generating frequency, i.e., the inference result. Furthermore the conditions are set within the knowledge base 11 for each factor of sales, and plural estimated sales amounts are set to each of these conditions for each of different generating frequencies. Thus an estimated total amount of sales is obtained by accumulating the estimated sales amounts corresponding to the highest generating frequency of the corresponding conditions for each factor of sales. Then it is possible to obtain a more accurate and minute estimated total amount of sales including an error range.</p> |
