Abstract

Disclosed herein is a mutual agreement type sale price determination method using cumulative distributions. The sale price determination method includes the steps of storing offered selling prices, desired quantities of commodities to sell, and personal information from the sellers, and offered purchasing prices, desired quantities of commodities to purchase, and personal information from the purchasers; obtaining cumulative distributions of the desired quantities of commodities to sell by arranging the offered selling prices and the desired quantities of commodities to sell in order ranging from a lowest price to a highest price; obtaining cumulative distributions of the desired quantities of commodities to purchase by arranging the offered purchasing prices and the desired quantities of commodities to purchase in order ranging from the highest price to the lowest price; and determining a sale price and the quantities of commodities for sale based on the cumulative distributions of the desired quantities of commodities to sell and purchase.

Claims

1. A mutual agreement type sale price determination method using cumulative distributions, in which a plurality of purchasers and a plurality of sellers determine a sale price to trade commodities using an on-line auction method, comprising:

a first step of receiving offered selling prices, desired quantities of commodities to sell, and personal information from the sellers, and offered purchasing prices, desired quantities of commodities to purchase, and personal information from the purchasers through an input unit, and storing them in a storage unit;

a second step of a price determination unit obtaining cumulative distributions of the desired quantities of commodities to sell by arranging the offered selling prices and the desired quantities of commodities to sell, which are input from the sellers, in order ranging from a lowest price to a highest price with respect to a reference price;

a third step of a price determination unit obtaining cumulative distributions of the desired quantities of commodities to purchase by arranging the offered purchasing prices and the desired quantities of commodities to purchase, which are input from the purchasers, in order ranging from the highest price to the lowest price with respect to the reference price;

a fourth step of the price determination unit arranging the cumulative distributions of the desired quantities of commodities to sell and the cumulative distributions of the desired quantities of commodities to purchase according to individual prices between the lowest and highest prices with respect to the reference price, and comparing the cumulative distributions with each other; and

a fifth step of the price determination unit determining at least one price, at which, in the cumulative distributions of the desired quantities of commodities to sell and purchase, a quantity of commodities for sale is maximal and a cumulative deviation is minimal, to be the sale price, and determining the quantity of commodities, which is available for sale at the determined sale price, to be a quantity of commodities for sale.

2. The mutual agreement type sale price determination method according to claim 1, further comprising, if the number of the determined sale prices is two, a sixth step of comparing cumulative quantities of commodities to purchase and cumulative quantities of commodities to sell at the determined sale prices, determining a higher price to be the sale price when a cumulative quantity of commodities to purchase is greater than a cumulative quantity of commodities to sell, and a lower price to be the sale price when a cumulative quantity of commodities to sell is greater than a cumulative quantity of commodities to purchase, and determining an average of two sale prices to be the sale price when a cumulative quantity of commodities to purchase and a cumulative quantity of commodities to sell are the same, or cumulative quantities of commodities to purchase and cumulative quantities of commodities to sell are symmetrically crossed.

3. The mutual agreement type sale price determination method according to claim 2, further comprising, if the number of the determined sale prices is three or four, a seventh step of comparing cumulative quantities of commodities to purchase and cumulative quantities of commodities to sell at the determined sale prices, and determining an average of a higher price, at which the cumulative quantity of commodities to purchase is greater than cumulative quantity of commodities to sell, and a lower price, at which the cumulative quantity of commodities to sell is greater than the cumulative quantity of commodities to purchase, to be the sale price.

4. The mutual agreement type sale price determination method according to claim 1, further comprising an eighth step of determining a sale type by determining the quantity of commodities for sale based on the determined sale price, and classifying the personal information according to an area, sale characteristics, and a degree of preference.

8. The mutual agreement type sale price determination method according to claim 2, further comprising an eighth step of determining a sale type by determining the quantity of commodities for sale based on the determined sale price, and classifying the personal information according to an area, sale characteristics, and a degree of preference.

9. The mutual agreement type sale price determination method according to claim 3, further comprising an eighth step of determining a sale type by determining the quantity of commodities for sale based on the determined sale price, and classifying the personal information according to an area, sale characteristics, and a degree of preference.

5. A mutual agreement type sale price determination system using cumulative distributions, in which a plurality of purchasers and a plurality of sellers determine a sale price to trade commodities using an on-line auction method, comprising:

an input unit for receiving offered selling prices, desired quantities of commodities to sell, and personal information from the sellers, and offered purchasing prices, desired quantities of commodities to purchase, and personal information from the purchasers;

a storage unit for storing the offered selling prices, the desired quantities of commodities to sell, and the personal information input from the sellers, and the offered purchasing prices, the desired quantities of commodities to purchase, and the personal information input from the purchasers;
