Description

METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR MANAGING PRICE OF PRODUCT BASED ON PURCHASE HISTORY OF THE PRODUCT}

The present invention relates to a method, a system and a computer readable recording medium for managing a price of a product based on a product purchase history. More specifically, in a price system in which the reference price of the product is set to become lower as the cumulative purchase quantity of the product increases, the surplus profit generated by the increase in the cumulative purchase quantity is provided to the past buyer who purchased the product. A method, a system, and a computer readable recording medium for enabling refund.

In electronic commerce based on a communication network such as the Internet, a discount sales method is generally performed in which a seller provides a product (or service) at a discounted price within a limited range in order to achieve a purpose of attracting customers and increasing sales. have. As an example of a conventional discount sales method, when a plurality of buyers purchase a certain quantity or more of a product (aka joint purchase), the product price is discounted. If you give a discount.

However, since the conventional discount sales method is based on the idea of applying a discount only when a plurality of purchases of a predetermined quantity or more occur, a general buyer (for example, a general consumer, etc.) who purchases a small amount of goods. There is a limit to the limited opportunity for discounts.

The limitation of the conventional electronic commerce method may cause various problems in the product distribution structure.

First, from the point of view of the consumer, the consumer who is the final buyer through several stages of the intermediate distribution process of reselling the product purchased at a relatively low price at a relatively high price by a wholesaler capable of purchasing a large quantity of the product at once There is a problem that the price burden of the greater than the reasonable level occurs. In addition, even from the standpoint of the wholesale and retailer, there is a problem in that a large quantity of products are purchased at a time in order to secure a product at a discounted price, and then, the stock is damaged due to the remaining inventory. .

In addition, assuming a purchase form for expensive goods such as a car, it is difficult for a single buyer to purchase several expensive goods in order to receive a discount due to multiple purchases, and co-purchase If multiple buyers purchase expensive products at the same time in order to receive the discount due to, it is hard to exist, so there is almost no way to get discounts from multiple purchases or joint purchases. It is no exaggeration to say nothing.

However, if the conventional discount system based on the cumulative purchase quantity by one buyer is applied to the discount system based on the cumulative purchase quantity by a plurality of buyers, another problem may occur. Specifically, if you apply the discount system with one buyer without considering multiple buyers, you can purchase the product first because the later purchaser can receive more discounts than the first purchaser. There can be an unfair situation in which one person may lose money relative to the person who bought the product later, which causes the majority of buyers to postpone the purchase of the product in order to receive more discounts. Problems may occur that do not occur.

For example, assume a discount system that discounts the price of the product as the cumulative purchase quantity of the product increases. In addition, the discount system A that discounts the price of the product by 100 won for each increase in the number of purchases by one buyer for one purchase by multiple buyers, and the product even if the cumulative purchase quantity increases for the purchases by multiple buyers We can assume a discount system B that does not discount the price of the car. That is, in the case of the discount system A, a discount is provided to one buyer who purchased a plurality of products by himself, and in the case of the discount system B, a plurality of buyers who cannot actually purchase a plurality of products can be considered as the buyers. We do not offer discounts for the market, and such discounts are natural in the light of market principles.

However, according to the discount scheme B, which is applied to multiple purchases by multiple buyers, the merchandise seller has excessive surplus gains compared to the discount scheme A, because even if the cumulative purchase quantity increases, no discount is provided to the buyer. There is a problem of being taken. Even so, if you apply the discount system A, which applies to multiple purchases by one buyer, to multiple purchases by multiple buyers, later purchasers will receive much more discounts than the first purchaser. Therefore, as mentioned above, an unfair situation may occur such that the first purchaser is relatively injured relative to the later purchaser, and thus, the sale of the product may not be performed normally.

As a compromise for overcoming such a problem, a discount system can be assumed that provides a discount for a middle level between discount schemes A and B according to the overall cumulative purchase quantity for multiple purchases by multiple buyers. This eclectic discount system does not fundamentally solve the above-mentioned critical problem, although it may mean that a plurality of buyers may be provided with a predetermined discount benefit according to a plurality of purchases.

Therefore, even if a plurality of buyers purchase a small amount of goods at different points in time, all of the plurality of buyers can receive the same discount rate as the simultaneous purchase of cumulative purchase quantities by the plurality of buyers. There is a need for an electronic commerce method that can effectively solve the problems of the structure.

It is an object of the present invention to solve all the problems described above.

In addition, the present invention is a price system in which the reference price of the product is set to become lower gradually as the cumulative purchase quantity of the product increases, the past in the surplus profit of the seller additionally generated as the cumulative purchase quantity increases By reimbursing the buyer, it is another object to allow multiple buyers who purchase the product in small quantities at different points in time to receive an equal level of discount.

In addition, the present invention corresponds to the difference between the past reference price of the product and the current reference price to the past buyers of the product when the reference price of the product is gradually set lower as the cumulative purchase quantity for the product increases. By reimbursing the amount, it is another object to provide the same discount to all the buyers who purchased the product in small quantities at different points in time as if the product was purchased at the same time as the cumulative purchase quantity. .

In addition, the present invention allows a general consumer who purchases a small number of products several times to directly deal with the producer to receive a discounted price of the product, thereby increasing the price of the product unnecessarily due to a complicated distribution channel It is another object to improve the distribution structure.

In addition, the present invention is to allow a wholesale and retailer to be provided with a product at a discounted price even if the purchase of only the required quantity of goods, to reduce the burden of inventory and to cultivate human sales is another object.

In addition, the present invention allows all buyers to receive an equal level of discount regardless of the time of purchase, so that there is room for an unfair situation such that a person who purchases later receives more discounts than a person who purchased first. Another goal is to minimize, and thereby enable timed joint purchases (so-called multiple purchases).

In addition, the present invention is to set up a group of buyers to share the discount with each other based on the application information input from the buyer, so that it is possible to determine whether to provide a discount due to multiple purchases according to the buyer's will do.

Representative configuration of the present invention for achieving the above object is as follows.

On the other hand, such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or execute particular abstract data types, described below, in accordance with the present invention.

First, according to an embodiment of the present invention, the purchase history collection unit 210 may perform a function of collecting history information about the purchase of goods by the buyer. More specifically, the purchase history information collected by the purchase history collecting unit 210 may include information about the purchase product, purchase date, purchase quantity and purchase amount of each buyer, and such purchase history information is for each buyer and // Alternatively, the data may be classified in each product and stored in the database 240.

Next, the discount distribution unit 220 according to an embodiment of the present invention performs a function of refunding the surplus profit of the seller generated by the increase in the cumulative purchase quantity to the past buyer who purchased the corresponding product.

More specifically, according to an embodiment of the present invention, the discount benefit distribution unit 220, with reference to the purchase history information of at least one buyer collected by the purchase history collector 210, the product currently being purchased A function of determining a first reference price according to the cumulative purchase quantity in consideration of all the plural purchases by the plural buyers with respect to. Here, the first reference price refers to a reference price according to a general price system considering multiple purchases by a plurality of buyers, and according to an embodiment of the present invention, the plurality of buyers may firstly receive a refund amount before being refunded. 1 The base price will be applied.

In addition, according to one embodiment of the present invention, the discount benefit distribution unit 220, as a price compared to the first reference price, the cumulative purchase quantity applied to a plurality of purchases by one buyer with respect to the product currently purchased To determine a second reference price (ie, a reference price according to a price system to which a discount rate that is greater than the price system of the first reference price is applied according to the cumulative purchase quantity if one buyer purchases the product cumulatively). Perform the function.

According to an embodiment of the present invention, the first and second reference prices, which are set for a product, are an amount corresponding to at least a part of the seller's profits assuming that the product is sold at the same time as the cumulative purchase quantity. As a price determined by discounting from the normal price of, the logic for calculating the reference price of the product may be preset by a seller of the product, an operator of the price management system 200, and the like. In addition, according to an embodiment of the present invention, from a seller's point of view, more discounts to one buyer who purchased a plurality of products alone than a plurality of buyers that can not be seen as a purchase of a plurality of products substantially each of the buyers Since it is natural to provide a benefit, the first reference price can be set higher than the second reference price.

In general, since the profit of the seller due to mass sales increases as the sales quantity increases in consideration of scale gain, according to an embodiment of the present invention, the first and second reference prices of the product are the cumulative purchase quantity of the product. The more this can be set lower. For example, at least one of the first and second reference prices according to one embodiment of the present invention may be linear (i.e. equally spaced) or non-linear (i.e. non- It can be set to be lower (at equal intervals). Meanwhile, according to an embodiment of the present invention, when the cumulative purchase quantity of the product is larger than a preset value, even if the cumulative purchase quantity of the corresponding product increases, the reference price of the corresponding product is no longer lowered. The lower limit value of at least one of the second reference prices may be set.

Regarding the first and second reference prices of goods according to an embodiment of the present invention, reference may be made to the description of "reference price" described in the specification of Korean Patent Application No. 10-2009-0132887 filed by the applicant. It should be understood that the contents of the patent application specification are all incorporated herein.

In addition, according to an embodiment of the present invention, the discount benefit distribution unit 220 has purchased at least a portion of the discount amount additionally generated as the cumulative purchase quantity increases at a relatively expensive price before the current purchase Perform the function of determining to refund the buyer.

More specifically, the discount distribution unit 220 according to an embodiment of the present invention, in the product currently purchased by the current buyer, the current purchase quantity for the product, including the current purchase quantity for the corresponding product Assuming that the cumulative purchase quantity, the product is purchased at the same time as the cumulative purchase quantity, the first reference price and the second reference price, based on the first reference price and the second reference price corresponding to the price charged for the product, A function of determining to refund at least one part of the amount obtained by multiplying the current purchase quantity by the present purchase amount to at least one past buyer who purchased the product before the current purchase.

According to one embodiment of the invention, the amount refunded to at least one past buyer may be determined based on the past price that the buyer was applied to the product, an example of how to determine the refund amount for each past buyer Is represented by Equation 1 below. However, according to Equation 1, it can be assumed that the same distribution is made to each past buyer, but is not necessarily limited thereto, and may also add a differential element to the distribution.

&Quot; (1) "

{(f (k)-g (k)) xj} x {n / (k-j)}

In Equation 1, j denotes a current purchase quantity, k denotes a cumulative purchase quantity including a current purchase quantity, and f (k) and g (k) are first and second criteria according to the cumulative purchase quantity k, respectively. The price, n indicates the number of products purchased in the past by past buyers who are eligible for reimbursement, and (k-j) is the number of past buyers (but if the same person purchases them at different times, they are treated as other buyers) ).

Referring to Equation 1, as compared with the past point in time when the past buyers purchased the product, the current reference price applied to the product as the cumulative purchase quantity of the product at the present time increases the past reference that the past buyer was applied Even if the price is lower than the price and the surplus profit of the seller increases due to the difference between the first reference price and the second reference price, the past purchaser may receive at least a portion of the amount corresponding to the difference between the first reference price and the second reference price. As a result, even a person who has purchased a product in the past can be provided with a level of discount equal to that of the person who is currently purchasing the product and can prevent the seller from taking too much surplus profit.

3 is a diagram exemplarily illustrating a configuration for refunding a predetermined amount to a past purchaser according to an embodiment of the present invention. For reference, FIG. 3 shows the first and tenth items of a in each purchase in the case where the first to tenth purchasers purchase goods a one by one and then the eleventh time when the buyer buys five goods a. In addition to the second reference price, at least one of the first to the tenth time of every first to eleventh time of purchase occurs as the first and second reference prices of the product a gradually decrease in each purchase. The table shows the amount of refunds to buyers who purchase at the time.

First, the refund process in the first to tenth purchases will be described. In FIG. 3, the normal price of the product a may be set to 10,000 won, and the reference price of the product a may be set lower as the cumulative purchase quantity increases. For example, the first reference price of the product a is the cumulative purchase. If the quantity is one 10,000 won, the cumulative purchase quantity is two 9,900 won, ..., if the cumulative purchase quantity is 10, it can be set to 9,100 won, the second reference price of product a is the cumulative purchase quantity is 1 It can be set to 10,000 won for individuals, 9,800 won for two cumulative purchases, and 8,200 won for ten cumulative purchases. Here, the "cumulative purchase quantity" refers to the total purchase quantity corresponding to the first to tenth times by at least one buyer, as mentioned above.

Referring to FIG. 3, (i) in the first purchase, when the first purchaser purchases one commodity a, the cumulative purchase quantity is one and the first purchaser has one cumulative purchase quantity. The product a can be purchased for 10,000 won by applying the first reference price of a. (ii) Next, in the second purchase, when the second purchaser buys one product a, the cumulative purchase quantity is two, and the second purchaser has the cumulative purchase quantity of two products a You can purchase product a for 9,900 won by applying the first reference price of 9,900, where the seller has 9,900 as the first reference price of product a when the cumulative purchase quantity is two compared with the case of multiple purchases by one buyer. Since it can be seen that the surplus profit corresponding to 100 won, which is the amount less than the second reference price of 9,800 won, according to an embodiment of the present invention, the surplus profit of the 100 won in the second purchase The amount may be refunded to the first purchaser, who is the former purchaser. (iii) Similarly, in the tenth purchase, when the tenth purchaser purchases one commodity a, the cumulative purchase quantity is ten, and the tenth purchaser has the cumulative purchase quantity of ten commodities a Receive the first reference price of 9,100 to purchase the product a, where the seller, compared to the case of multiple purchases by a single buyer of 10, when the cumulative purchase quantity is 10, which is the first reference price of the product a 9,100 Since it can be seen that the surplus profit corresponding to 900 won, which is the amount less than the second reference price of 8,200 won from the won, according to an embodiment of the present invention, the surplus profit of the 900 won in the tenth purchase The amount can be divided equally and can be refunded by 100 won each to the first to ninth buyers, the former buyers. On the other hand, in the above embodiment has been described by taking only the case where the quantity of the product a to be purchased in each purchase by each purchaser as an example, but is not necessarily limited thereto.

For example, in the eleventh purchase of FIG. 3, it may be assumed that the eleventh buyer purchases five items a at a time, in which case the cumulative purchase quantity is 15, and the 15th buyer is the cumulative purchase quantity. The product a can be purchased for 8,600 won by applying the first reference price of the product a in the case of 15 items, and the seller can purchase the product a when the cumulative purchase quantity is 15 as compared with the case of multiple purchases by one buyer. According to an embodiment of the present invention, since the surplus profit corresponding to 1,400 won is subtracted from the first reference price of 8,600, subtracting the second reference price of 7,200 won. In this case, the surplus profit amount of 1,400 won will be divided equally and can be refunded 140 won each to the first to tenth buyers who are past buyers.

As described above, according to an embodiment of the present invention, the difference between the first reference price and the second reference price for the product may increase as the purchase continues and the cumulative purchase quantity increases. The amount refunded to each past buyer at each point of purchase may also vary.

As described above, when the surplus profits of the seller are distributed and refunded to the past buyers at each time of purchase, the total discount benefits provided to the plurality of buyers are equally converged, in particular, the first time of FIG. 3. It can be seen that the discounts are the same with respect to the tenth buyer.

As such, when all buyers receive the same discount according to an embodiment of the present invention, a discount distribution according to another embodiment of the present invention as described below as a discount distribution method for achieving the same effect. You can also assume the method.

The discount distribution unit 220 according to another embodiment of the present invention provides the same discount benefits to all of the plurality of buyers who purchased the products in small quantities at different points in time, as in the case of purchasing the corresponding products at one time by the cumulative purchase quantity. To perform the function.

More specifically, according to another exemplary embodiment of the present invention, the discount distribution unit 220 refers to the purchase history information of at least one buyer collected by the purchase history collecting unit 210, which the current buyer wants to purchase. It performs the function of determining the base price of the goods (that is, ordering).

More specifically, according to another embodiment of the present invention, the discount benefit distribution unit 220, with reference to the purchase history information of at least one buyer collected by the purchase history collection unit 210, the product currently being purchased With respect to the reference price according to the cumulative purchase quantity considering all the multiple purchases by a plurality of buyers can be determined.

According to another embodiment of the present invention, a reference price charged for a product is determined by discounting an amount corresponding to at least a part of a profit that a seller obtains by selling a product of a cumulative purchase quantity at a time from a normal price of the product. As a price, a logic for calculating a reference price of a product may be preset by a seller of the product, an operator of the price management system 200, and the like.

In general, in consideration of scale gain, the seller's profit due to mass sales increases as the sales quantity increases, and according to another embodiment of the present invention, the reference price of the product may be set lower as the cumulative purchase quantity of the product increases. Can be. For example, the reference price according to another embodiment of the present invention is set to be lowered linearly (ie at equal intervals) or non-linearly (ie at non-equal intervals) as the cumulative purchase quantity increases. Can be. Meanwhile, according to another embodiment of the present invention, when the cumulative purchase quantity of the product is larger than the preset value, even if the cumulative purchase quantity of the product increases, the reference price of the product does not become lower anymore. The lower limit value may be set.
