Demand-and-supply intervening system, demand-and-supply intervening method, and demand-and-supply intervening support program

摘要

A demand-and-supply intervening system which supports determination of a demand-and-supply relationship between users in association with demand resources and supply resources between a plurality of users, comprises an entry acquisition unit for creating an entry set by collecting a plurality of entries each of which has a plurality of resources as demand/supply objects and a combinatorial condition to be satisfied between resources, and a candidate group determination unit for extracting a candidate group of entries so that all entries included in the candidate group satisfy combinatorial conditions included in each entry when extracting the candidate group having a plurality of entry which includes at least one entry designated as a base point, and determining the presence/absence of demand-and-supply relationships between demand and supply resources between entries which belong to the candidate group and demand-and-supply quantities.
