Hereinafter, detailed configurations and functions within such a macroscopic configuration will be described.

2 is a block diagram showing the basic configuration of the system of the present invention, and FIG. 3 is a conceptual diagram showing an embodiment of information and matching between a seller and a buyer according to the present invention.

2, the system 1 of the present invention is basically a member subscription module 110, a sales information management module 120, a purchase condition management module 130, a matching module 200, a payment management module ( 300).

The member registration module 110 serves to process member registration by classifying sellers and buyers. Here, the seller may be a person or a company engaged in manufacturing, crafting, wholesale, and retailing of metal materials. Such a seller may be a business that sells such metal materials in Korea or abroad, and may be authenticated as a seller by submitting a business registration certificate or documents proving that sales are in progress and become a member. How to receive payment and deposit You can enter and save the account together. In addition, the purchaser may be a person or company who wants to purchase the metal material sold by the seller, and may write personal information, payment method, and the like. This member registration processing method is a known technology, so a detailed description thereof will be omitted.

The sales information management module 120 provides a function of receiving price, thickness, size, and delivery date for each metal material from a seller and updating sales information for each metal material in real time.

In this case, the metal material is a material made of a metal such as aluminum, iron, copper, etc. as a raw material, and information on the metal material handled and sold by each seller may be input. Such metal materials may be sold in large quantities or in small quantities, may be raw materials or processed products, and sales information is different for each seller, so there is no specific limitation on this. The seller can update the sales information in real time by inputting such sales information through the seller's terminal, and the updated sales information can be input to the server of the system 1, and accordingly, as shown in FIG. You can check the updated sales information through their terminals.

In addition, sellers often import the above metals. In this case, the process of "import decision-L/C open-B/L ship-in transit-arrival-customs clearance-arrival at head office" is provided to those who wish to purchase or who can purchase. It is shown and the price can be presented at each stage, so that a supply promise can be made with the most favorable discount condition for the buyer who placed the order in the import decision stage, the first stage of import, and in the case of the next stage, L/C open stage, A small discount condition can be presented, and the discount width can be presented slightly lower as the process goes down. That is, the buyer who places the order from the initial import decision stage can purchase on the most favorable terms. Through this process, the seller secures pre-orders from the buyers from the import decision stage, and can achieve the complete sales target by delivering it to all buyers without the burden of inventory upon arrival in Korea. From the perspective of sellers in importing metal raw materials, if inventory increases due to sluggish sales after import, there is a risk that funds are tied up for a long period of time, and due to such risks, they are unable to implement more aggressive and smooth imports and supply and hesitate. In addition, looking one step ahead in the value chain, producers from the production stage also have a burden on the risk of inventory of production. Likewise, as the primary supplier (import and distributor) consumes the production according to accurate purchase forecasts, By being able to execute production with accurate predictions, it is possible to eliminate the risk of losing money across industries. In addition, in the payment method to be described later, it is interlocked to fit the system of the present invention, and when pre-orders are placed in each process, funds are tied with escrow at a certain credit card limit, and payment is automatically made when supply/delivery is completed. You can let it go.

The purchase condition management module 130 provides a function of receiving and storing purchase condition information for each metal material from a purchaser. In this case, the purchase condition information may be a condition that the purchaser wants to purchase, and may be input as information such as the type, size, number, and price of the desired metal material. For example, as shown in FIG. 3, a buyer wants to purchase 1000 aluminum of 150 * 150 mm plate format and can enter purchase condition information through a user terminal, and such purchase condition information is stored in the web or app of the system 1 It can be displayed and printed.

The matching module 200 compares the sales information and purchase condition information to connect the seller and the buyer. In other words, it connects the seller and the buyer to find a seller who sells metal materials that meet the purchase condition information desired by the buyer.

At this time, the seller matching the purchase condition information to the buyer may be automatically matched on the system 1, but as can be seen with reference to FIG. 3, a plurality of sales information can be output as a list and provided to the buyer. You can view the list and finally select the seller to trade.

The payment management module 300 provides a function of determining whether the purchaser has paid the seller. That is, it is possible to determine whether or not payment is made by identifying the seller's payment method and the buyer's payment method. Since the technology for determining whether such payment is paid is a known technology, a detailed description will be omitted.

By issuing a specific credit card for the payment method in this system, the purchase limit is automatically determined according to the credit level of each purchaser, and purchases can be made within the suggested credit limit amount. This allows the limit to be determined according to the amount of purchase and the creditworthiness of the individual or company. In addition, after checking the discount price for each supply stage suggested by the seller, if a pre-order is placed at a specific stage, an escrow is formed within this card limit, and the funds are tied up, wait for payment with a holding certificate, and immediately upon receipt of delivery (or for example, 48 hours Automatic confirmation within) Payment can be made to the seller /

In this case, the matching module 200 may include a reverse auction bidding unit 210.

The reverse auction bidding unit 210 serves to match the seller selected by the buyer by re-determining a price among the sale information provided to the buyer by the plurality of sellers. Here, the plurality of sellers matched with the buyer may re-determine the price to close the transaction with the buyer. Accordingly, the buyer can check the price readjusted by the seller and finally select the seller to trade.

In addition, the payment management module 300 may include a payment intermediary 310, and the payment intermediary 310 may include an asscrow part 311 and a payment payment part 312.

The ascrow part 311 provides a function of depositing at least a part of the price of the metal material supplied by the seller from the buyer, and the payment part 312 is transferred to the buyer by the metal material supplied by the seller It performs a role of determining whether or not it has been done, and delivering the deposit to the seller.

Here, the deposit is essentially included in the purchase price during a transaction, and an amount generated by canceling an order, refunding the payment amount, refunding the difference in excess deposit, etc. that may occur during a transaction between the seller and the buyer may be treated as the deposit. These deposits may be used to promise a transaction with the seller by paying in advance before paying the full amount as a partial amount of the total amount. At this time, the ratio of the deposit in the price of the metal material may be arbitrarily set by the purchaser as 5%, 10%, etc. of the total purchase price, but may be set automatically in the system 1.

In addition, after the metal material is delivered to the purchaser, when the purchaser receives the metal material, the purchaser can check whether the metal material has been delivered through the process of determining that the metal material has been delivered through the purchaser's terminal.

In addition, the payment part may include a function of transmitting a message requesting payment of the balance excluding the deposit from the price of the metal material to the buyer at the time of payment of the deposit. At this time, the buyer can pay the deposit at the price of the metal material to the seller in advance, and "The deposit has been confirmed. Please pay the rest." You can request the buyer to pay the balance with a message such as. After requesting the payment of the balance in this way, when the deposit of the balance is confirmed, the seller can provide the metal material to the buyer.

As another embodiment, the system 1 may evaluate a purchaser based on purchase information of the purchaser by including the purchase index calculation module 140. At this time, the purchase index can be evaluated by weighting the frequency of participation by the buyer from the import decision stage (ie, the frequency reserved in advance on the import route). In addition, buyers who frequently use pre-orders may be offered prices on more favorable terms.

The purchase index calculation module 140 may provide a function of calculating a purchase index based on the number and quantity of purchases of the metal material for each purchaser, and in this case, the purchase index may be calculated through Equation 1 below. .

Equation 1.

Deposit ratio (deposit/standard deposit) when purchasing the first metal material,

The number of purchases of silver metal,

Is the period from the date of the purchaser's first metal material purchase to the last metal material purchase date,

May be a weight for each metal material.

Here, the purchase index means the score of the buyer evaluated through the purchase information of the buyer, and this can be used as an index of trust in the transaction with the buyer to the seller. In addition, the weight of each metal material is a value that can be set differently for each metal material being sold, and it may be set differently according to the type of metal material and information of the seller, and there is no specific limitation on how to set this. In addition, the deposit ratio is a value obtained by dividing the deposit by the standard deposit, and the'standard deposit' may be preset to 20 to 30% of the metal material price. That is, according to Equation 1, the number and quantity of metals purchased by the buyer is large, the price of the metal is high, and the more frequent the purchase is, the higher the purchase index can be calculated, and the higher the purchase index, the higher the reliability to sellers. have.

Accordingly, the ascrow part 311 may differentially adjust the amount of the deposit according to the high or low of the purchase index. That is, the purchaser's reliability is determined through the calculated purchase index, and the amount of the deposit is adjusted accordingly. For example, a buyer whose purchase index is calculated higher can be adjusted by differentially lowering the amount of the deposit.

Furthermore, the system 1 may further include a deposit payment determination module 400 and a deposit payment module 150.

The deposit payment determination module 400 includes a payment request input unit 410 and a payment determination unit 420.

The payment request input unit 410 provides a function of receiving a request for payment of the deposit from the purchaser. In other words, when purchasing metal materials, the buyer can request the seller to pay the deposit to be paid in advance. For example, when the price of a metal material is 10 million won and the deposit is 3 million won, the purchaser may request to pay 3 million won to be paid in advance to the system 1 of the present invention. That is, the payment of the deposit can be said to be a kind of loan system (1).

The payment determination unit 420 determines whether or not the deposit requested for payment is paid based on the purchase index. At this time, since the purchase index is directly related to the reliability of the purchaser, the system 1 may determine the payment of the deposit by determining the purchase index of the purchasers. At this time, the purchase index as a reference may be arbitrarily set by the administrator of the system 1 or may be automatically set on the system 1.

The deposit payment module 150 serves to pay the deposit to the purchaser when it is determined that the deposit will be paid to the purchaser. At this time, the payment of the deposit may be made through account information input by the purchaser when registering as a member in the server of the system 1. The purchaser who received the deposit can use the amount paid as a deposit when purchasing metal materials.

Further, the system 1 may additionally include a repayment management module 500 and a deposit payment remanagement module 600.

The repayment management module 500 includes a repayment condition setting unit 510 and a repayment determination unit 520.

The repayment condition setting unit 510 provides a function of setting repayment conditions including an expected repayment date, repayment amount, and interest rate of the deposit.

At this time, the expected repayment date means the date on which the deposit will be repaid from the buyer who received the deposit, and the repayment amount means the amount of the deposit paid to the buyer, and the interest rate is the interest rate applied according to the period from the payment date to the expected repayment date (at this time The interest rate may be the interest rate set by the system (1) of the present invention, or the interest rate set by the administrator of the system (1) of the present invention, and there is no limitation on it.) do. In addition, among the repayment conditions, the expected repayment date may be designated by the purchaser or by the administrator of the system 1 of the present invention, and there is no limitation on this.

Repayment determination unit 520 performs a role of generating repayment information including whether the buyer repays the deposit, a repayment period from the payment date to the repayment date, the amount of the repaid deposit, and the number of repayments. In other words, when the buyer repays the deposit, it is determined whether the above repayment conditions are met, and the repayment period, which is the period from the payment date when the deposit is paid to the repayment date when the deposit is repaid, and the amount of the deposit repaid by the buyer, and the deposit are divided. In the case of repayment, it provides the function of generating repayment information including the number of repayments.

The deposit payment remanagement module 600 includes a deposit repayment degree grasping unit 610 and a repayment determination unit 620.

The deposit repayment degree grasping unit 610 provides a function of determining a deposit repayment degree, which is whether the purchaser has repaid the deposit to meet the repayment conditions based on the purchase index and the repayment information. That is, the deposit repayment degree is a numerical value that provides a function of determining whether the buyer has sincerely repaid the paid deposit, and it can be calculated based on the number of times the deposit is paid to the buyer and the number of times the deposit is repaid from the buyer.

This deposit repayment degree can be calculated through Equation 2 below.

Equation 2.

,

Means.

Equation 2 above is an equation for calculating the degree of repayment of the deposit by the buyer based on the number of times the deposit is paid and the number of repayments of the deposit, and through this, it is possible to numerically determine how faithfully the buyer repays the deposit.

At this time, the amount weight is a value that is weighted according to the high and low of the amount of the deposit paid to the buyer, and the repayment weight means a value that is weighted according to the high and low of the number of repayments. That is, the greater the amount of the deposit, and the more the buyer repays the deposit, the greater weight is given, so that the repayment integrity of the buyer (that is, the repayment of the deposit) can be more accurately calculated. These amount weights and redemption weights can be set by the administrator of the system 1 of the present invention, and there is no limitation on the setting method.

The repayment determination unit 620 plays a role of determining whether to repay the deposit to the buyer based on the repayment of the deposit. That is, the calculated deposit repayment degree can be said to be a measure of how faithfully the buyer repays the deposit, and it is possible to determine whether the deposit repayment in the system 1 by referring to this. At this time, the administrator of the system 1 can arbitrarily set the exact value of the deposit repayment degree for which the deposit can be repaid, and there are no specific restrictions.

In addition, the deposit payment remanagement module 600 may include a payment weight calculation unit 630 that calculates a payment weight for the purchaser based on the deposit repayment degree.

In this case, the payment weight may be calculated through Equation 3 below.

Equation 3.

Is the above deposit repayment,

Is the quantity of metal at the most recent point of purchase of metal,

The price of the metal at the most recent point of purchase of the silver metal,

Refers to the deposit rate when purchasing a metal material at the most recent point of purchase.

Equation 3 above is an equation for calculating the payment weight based on the redemption degree, quantity of metal material, price, and deposit ratio, and the purchaser's metal material transaction ability through the purchaser's entire metal material transaction record according to the height of the calculated payment weight. Make it easy to figure out numerically. That is, it is possible to more accurately grasp the purchase reliability of the purchaser by further reflecting the numerically displayed reliability of the purchaser's metal material transaction to the calculated purchase index.

Accordingly, the purchase index calculation module 140 may include a function of recalculating the purchase index based on the payment weight.

In this case, the purchase index may be recalculated through Equation 4 below.

Equation 4.

Is the weight of each metal material,

Means the payment weight.

That is, Equation 4 is an equation for recalculating the purchaser's purchase index by further reflecting the payment weight in Equation 1, and through this, it is possible to more accurately grasp the purchaser's metal material trading ability and reliability.

Furthermore, the deposit payment remanagement module 600 may include a purchase accuracy calculation unit 640.

The purchase accuracy calculation unit 640 provides a function of calculating the purchase accuracy of the purchaser based on the number of transactions, quantity, and price of the metal material, and the deposit ratio of the deposit.

In this case, the above-described purchase accuracy may be calculated through Equation 5 below.

Equation 5.

Is

The price of the second metal,

Is

Deposit rate for the first metal purchase,

Is the period from the purchase start date of the purchaser to the time of observation,

Means the total number of metal material transactions by the buyer.

Equation 5 is an equation that calculates the purchaser's purchasing accuracy based on the quantity, price, deposit ratio, observation period, and the number of transactions of the purchaser, and the purchaser's desired metal material according to the calculated level of purchase accuracy. It is possible to determine whether it matches the seller who sells the product and whether it is conducting the desired transaction. In other words, purchase accuracy is a measure of how accurately a buyer has made a transaction he wants.

The calculated purchasing accuracy is further reflected when calculating the payment weight, so that the buyer's ability to trade metals can be more accurately identified. Therefore, the purchase accuracy calculated by Equation 5 above not only numerically indicates the purchase ability of the purchaser, but the system 1 can select a purchaser to pay the deposit according to the high or low purchase accuracy.

Accordingly, the payment weight calculation unit 630 may recalculate the payment weight based on the purchase accuracy.

In addition, the payment weight may be recalculated through Equation 6 below.

Equation 6.
