<P>PROBLEM TO BE SOLVED: To highly accurately prepare an estimate. <P>SOLUTION: An estimate preparation method includes: a step S5 for referring to a unit price information table in which a plurality of components are made to correspond to a plurality of unit prices, and calculating a plurality of component unit prices corresponding to the plurality of components; a step S8 for calculating a plurality of component price movements corresponding to the plurality of components on the basis of purchase scheduled time; and a step S9 for preparing an estimate in which the plurality of components are made to correspond to a plurality of scheduled unit prices. At the time, the scheduled unit price corresponding to an optional component is calculated on the basis of the component price movement corresponding to the optional component among the plurality of component price movements and the component unit price corresponding to the optional component among the plurality of component unit prices. By such an estimate preparation method, the plurality of scheduled unit prices are highly accurately calculated even when the unit price to purchase the component varies depending on the purchase scheduled time, and the estimate is highly accurately prepared. <P>COPYRIGHT: (C)2012,JPO&INPIT |
