<P>PROBLEM TO BE SOLVED: To set a preferable reference date for an order date with respect to past commodity order history to be referred to in placement of commodity order. <P>SOLUTION: The commodity order information processor generates, upon input of an order date (D<SB>1</SB>/M<SB>1</SB>/Y<SB>1</SB>) for performing placement of commodity order from an input means, day-of-the-week specification information specifying which day of the week the order date corresponds to and week specification information specifying what number of the weeks of M<SB>1</SB>/Y<SB>1</SB>the D<SB>1</SB>/M<SB>1</SB>/Y<SB>1</SB>corresponds to, and calculates a reference date (D<SB>2</SB>/M<SB>2</SB>/Y<SB>2</SB>) before the order date, which is determined by the week specification information and the day-of-the-week specification information of the same month as that of the order date. When the D<SB>2</SB>/M<SB>2</SB>is included in a predetermined allowable period including the D<SB>1</SB>/M<SB>1</SB>, the processor outputs the calculated reference date to an output means. <P>COPYRIGHT: (C)2009,JPO&INPIT |
