<p><P>PROBLEM TO BE SOLVED: To more accurately obtain an accumulated quantity in future of a restriction-object substance. <P>SOLUTION: The actual values of use ratios in past multiple periods of respective candidate components are statistically processed, if the multiple candidate components exist to one component, to obtain the representative use ratios of the respective candidate components (S9), and the delivery quantities in future respective periods of restriction-object substances are obtained by using: the estimated delivery quantities of one or more products for every future period; the restriction-object substance content ratios in the respective candidate components of the respective products; and the representative use ratios of the respective candidate components in case that multiple candidate components exist in one component (S10). Then, the accumulated quantities of the restriction-object substances up to future respective periods and for each of the future respective periods are obtained by using the delivery quantities of the restriction-object substances for the future respective periods and are stored in a storage device (S11). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
