<P>PROBLEM TO BE SOLVED: To calculated expectation effect for each management condition in multistep commercial flow and to establish optimum management condition, that is, an optimum sales condition on a management entity side based on the expectation effect. <P>SOLUTION: A demand prediction model setting part 14 sets a predicted demand of a commodity for one or a plurality of terminal conditions about trade of the commodity by a terminal entity in the multistep commercial flow. A probability distribution calculation part 16 calculates a realization frequency for each terminal condition to the corresponding management condition for one or each of a plurality of management conditions related to the trade of the commodity by the management entity in the multistep commercial flow. Based on the predicted demand and the realization frequency, expectation effect in the multistep commercial flow is calculated for each management condition. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
