Matching support device, matching support system, and program

A method using a matching device communicable with a supplier terminal of a supplier and a demander terminal of a demander, the method comprising:

• storing, to a data storage of the matching device, supply information from the supplier terminal and demand information from the demander terminal;
• matching the supply information and the demand information;
• calculating at least one of (i) a demander achievement value of a demander that is calculated based on demand information sent from the demander terminal of the demander within a predetermined past period and a result of transaction that has been actually carried out based on a matching using the demand information within the predetermined past period, and (ii) a supplier achievement value of a supplier that is calculated based on supply information sent from the supplier terminal of the supplier within a predetermined past period and a result of transaction that has been actually carried out based on a matching using the supply information within the predetermined past period;
• and
• calculating at least one of (a) a demander reliability based on the demander achievement value, the demander reliability indicating a reliability of demand information presented by the demander, and (b) a supplier reliability based on the supplier achievement value, the supplier reliability indicating a reliability of supply information presented by the supplier.

A non-transitory computer-readable storage medium having recorded thereon a computer program to control a processor of a matching device communicable with a supplier terminal of a supplier and a demander terminal of a demander such that the computer program causes the processor to:

• store, to a data storage of the matching device, supply information from the supplier terminal and demand information from the demander terminal;
• match the supply information and the demand information;
• calculate at least one of (i) a demander achievement value of a demander that is calculated based on demand information sent from the demander terminal of the demander within a predetermined past period and a result of transaction that has been actually carried out based on a matching using the demand information within the predetermined past period, and (ii) a supplier achievement value of a supplier that is calculated based on supply information sent from the supplier terminal of the supplier within a predetermined past period and a result of transaction that has been actually carried out based on a matching using the supply information within the predetermined past period;
• and
• calculate at least one of (a) a demander reliability based on the demander achievement value, the demander reliability indicating a reliability of demand information presented by the demander, and (b) a supplier reliability based on the supplier achievement value, the supplier reliability indicating a reliability of supply information presented by the supplier.
