<P>PROBLEM TO BE SOLVED: To provide an information processor, in which an estimation work can be efficiently proceeded even in a state where all items necessary for estimation are not determined and an estimation result with minimized error can be obtained, and a control method and a program therefor. <P>SOLUTION: The project cost estimation support system 100 comprises an estimate characteristic setting part 104, a result information storage part 102 comprising a RAM and the like, an influence coefficient setting part 103 comprising a CPU and the like, a similar work extraction part 105 and an estimated cost calculation part 107, and an estimate information display part 106 comprising a monitor and the like. The estimate characteristic setting part 104 sets, when an estimate characteristic input screen 110 includes a characteristic item having no user input, estimate characteristic data with this characteristic item being undefined, and the similar work extraction part 105 and the estimated cost calculation part 107 calculate a total similarity and an estimated total cost while excluding the undefined characteristic item. <P>COPYRIGHT: (C)2007,JPO&INPIT |
