Japanese Patent Laying-Open No. 2015-053060

  In the case of purchasing a plurality of products or services of the same type or different types, a method and system for presenting an optimal discount rate to a customer to be purchased has not been known. In general, discounts that stimulate purchasers' willingness to purchase by presenting services that set discount rates and discount amounts as “summary discount” as the number of purchases and purchase amount increase are known. However, it cannot be calculated quantitatively, and is often set arbitrarily according to each store. For this reason, there may be situations where the business is not feasible, for example, the cost is discounted and the profit margin cannot be obtained.

  The present invention has been made in view of the above problems, and the discount rate increases as the number of purchases of goods, services, and the like increases. On the other hand, the discount rate is a certain upper limit discount rate. The purpose is to propose a discount rate setting method, apparatus, system, etc. that can be easily calculated and set so as not to exceed.

  The price determination method by the information processing apparatus according to the present invention is a method for determining individual sales prices of a product or service when discounting a plurality of products or services according to the number of purchases. N-1) A value obtained by dividing the difference between the discount rate of the product or service to be purchased at the point and the maximum discount rate set in advance by the preset discount addition ratio (M) (N-1 ) A step of calculating a discount rate added to the discount rate of the product or service purchased at the point as the discount rate of the product or service purchased at the Nth point (where N is an integer of 2 or more), and the Nth point And a step of calculating an actual sales price by applying a discount rate calculated for a product or service to be purchased.

  In the price determination method by the information processing apparatus of the present invention, preferably, the first discount rate of the product or service is smaller than the maximum discount rate at the upper limit, and the calculated discount rate is always the same regardless of the value of N. It is a value between the first discount rate of the product or service and the maximum discount rate of the upper limit.

  The total billing amount determination method by the information processing apparatus of the present invention preferably includes a step of calculating a selling price for each of all purchased goods or services, summing up and calculating the total billing amount. It is characterized by performing.

  The discount rate increases as the number of purchases of goods and services increases. On the other hand, the discount rate can be easily calculated and set so that it does not exceed a specific upper limit discount rate. A setting method can be proposed.

It is a conceptual diagram explaining the setting method of a discount rate in case the same purchaser purchases two or more same goods. It is a conceptual diagram explaining the setting method of a discount rate in case the same purchaser X purchases the different goods A, goods B, and goods C with which the discount rate was each set. It is a conceptual diagram explaining the setting method of a discount rate in case the same purchaser X purchases the different goods C, goods A, and goods B with which the discount rate was each set. In [Equation 6], when the discount rate a for each product is 5%, the upper limit maximum discount rate P is 10%, and the discount addition ratio M = 2, the setting value of the discount rate for the product with respect to the number of purchases It is explanatory drawing made into a graph. It is a flowchart explaining the calculation step in the case of determining and billing the final purchase amount (billing amount) with respect to the purchaser in the case of purchasing a plurality of products and services of the present embodiment.

  By using the product price determination method at the time of purchasing multiple products by the golden section method (golden ratio) described in the present embodiment, the purchaser can be provided with the expectation and reality that the discount rate increases as the number of purchases increases, The seller can obtain a sense of security that does not exceed a certain discount rate even if the discount rate increases according to the number of purchases. For example, it is possible to reduce a concern that a discount rate becomes too large and a situation in which a profit is not generated such as unexpectedly interrupting the cost.

(First embodiment)
FIG. 1 is a conceptual diagram illustrating a discount rate setting method when the same purchaser X1000 purchases a plurality of the same products A1200. For example, when the purchaser X1000 purchases one product A1200 in the cart 1500, the discount on the product A1200 is a discount of a%. In addition, when the purchaser X1000 purchases two products A1200 in the cart 1500, the second discount of the product A1200 is, for example,

It becomes.

  That is, if a = 5, it can be calculated as 7.5%. More specifically, if the non-discount price (for example, regular price) of the product A1200 is 100 yen, the first selling price is 95 yen minus 5% discount, and the second selling price is 7.5% discount. Subtracting 92.5 yen will result in a total charge of 95 yen + 92.5 yen = 187.5 yen.

  When the purchaser X1000 purchases three products A1200 in the cart 1500, the discount for the third product A1200 is, for example,

It becomes.

  That is, if a = 5, it can be calculated as 8.75%. More specifically, if the non-discount price (for example, regular price) of the product A1200 is 100 yen, the first selling price is 95 yen minus 5% discount, and the second selling price is 7.5% discount. After deducting 92.5 yen, the third selling price is 91.25 yen minus 8.75% of the discount, so the total of 3 items is 95 yen + 92.5 yen + 91.25 yen = 278.75 yen Amount of money.

  Furthermore, when the purchaser X1000 purchases four products A1200 in the cart 1500, the discount for the fourth product A1200 is

It becomes.

  That is, if a = 5, it can be calculated as 9.375%. More specifically, if the non-discount price (for example, regular price) of the product A1200 is 100 yen, the first selling price is 95 yen minus 5% discount, and the second selling price is 7.5% discount. Subtracted 92.5 yen, the third selling price is 91.25 yen minus 8.75%, and the fourth selling price is 90.625 yen minus 9.375%, so 4 The total amount charged is 95 yen + 92.5 yen + 91.25 yen + 90.625 yen = 369.375 yen.

  The billing amount calculated for each point in this way will eventually approach 90 yen in the above example as the number of sales increases, but never falls below 90 yen. In the above example, it does not exceed twice the initial discount rate of 5%. By setting a discount rate based on the golden section method, for example, it is possible to set a sales price that increases the discount rate according to the purchase quantity without falling below a certain cost. In the case of the present embodiment, the discount rate (discount) of the Nth product A1200 when purchasing N products A1200 (where N is an integer of 2 or more) is:

It can be expressed.

  In the above equation [4], the denominator “2” of the right term can be applied as an arbitrary number. For example, when it is desired to moderately suppress the degree of increase in the discount rate accompanying the increase in the number of purchases, the denominator can be increased to, for example, “3”, “4”, “2.5”, and the like. Also, for example, if you want to sharply increase the degree of increase in the discount rate that accompanies an increase in the number of purchases, reduce the denominator to, for example, “1.1”, “1.4”, “1.8”, etc. Is also possible. In other words, the discount rate (discount) of the Nth product A1200 when purchasing N products A1200 (where N is an integer of 2 or more) with a discount rate of 1% a is the upper limit. When setting the maximum discount rate to twice the initial discount rate (ie a% x 2),

It can be expressed.

  However, the discount addition ratio M is an arbitrary number of 1 or more. Similarly, when the maximum discount rate when increasing the discount rate associated with the increase in the number of purchases is set as P, the Nth item for purchase of N pieces (where N is an integer of 2 or more). The discount rate (discount) for

It can be expressed.

  However, the discount addition ratio M is an arbitrary number of 1 or more. As can be understood from the above [Equation 6], when a plurality of products A1200 are purchased, the N-th discount rate approaches P as the purchase quantity N increases. Never exceed. Therefore, by setting P to a value that is not cheaper than the cost, it is possible to set a discount rate that increases according to the number of purchases while securing a minimum profit. In addition, the calculated amount of 1 yen or less in the final total invoiced amount may be adjusted in practice by rounding down, rounding up, or rounding off as appropriate.

  FIG. 4 shows a discount rate for a product with respect to the number of purchases in the case of [Equation 6] where the discount rate a for each product is 5%, the maximum discount rate P is 10%, and the discount addition ratio M = 2. It is a figure explaining the setting value of a graph. As can be understood from FIG. 4, the discount rate for the product that was last added to the cart as the number of purchases increases is the discount rate immediately before that and the maximum discount rate (P = 10%). Half of the difference ((1 / M) = 0.5) will be added, but according to this method, even if the number of purchases increases, the maximum discount rate (P = 10%) will not be exceeded. Absent. For example, while preventing selling at a price that is below the purchase cost or break-even point, it is possible to provide the purchaser with pleasure and excitement that the discount increases as the number of purchases increases.

(Second embodiment)
FIG. 2 is a conceptual diagram illustrating a discount rate setting method in the case where the same purchaser X1000 purchases different products A1200, B1300, and C1400, each having a different discount rate. For example, the purchaser X1000 may purchase a cart 1500 with a discount A% product A1200, a discount b% product B1300, and a discount c% product C1400 one by one in this order. First of all, a discount rate of a% is applied to 1,001 products A12001 first put in the cart. For example, if the product A1200 is a 100 yen eraser and the discount is 5%, the price after applying the discount is 95 yen.

  Next, with respect to one product B1300 put in the cart as the second point, the discount rate in the case of purchasing two products B1300 is applied. That is, if the example of the first embodiment is used,

It becomes.

  That is, if b = 10, 15% can be calculated from [Equation 7]. More specifically, if the price without discount (for example, the regular price) of the product B1300 is 200 yen, the selling price is 170 yen minus 15% discount. That is, there is actually only one mechanical pen placed in the cart, but the second purchaser is the product purchased by the same purchaser X1000. It is assumed that a discount is set for the second mechanical pen when purchasing.

  Similarly, for one product C1400 placed in the cart as a third item for purchase by the purchaser X1000, the discount rate for purchasing three products C1400 is applied. That is, if the example of the first embodiment is used,

It becomes.

  That is, if c = 15%, the discount rate when buying two of these is 22.5%, and this can be calculated as 26.25% by substituting this into [Equation 8]. . More specifically, if the price without discount (for example, the regular price) of the product C1400 is 300 yen, the selling price is 221.25 yen minus 26.25% of the discount. That is, although there is only one pen case actually put in the cart, the same purchaser X1000 purchases the third item as the number of items purchased. A discount is set for the third brush case when purchasing three. Therefore, the total amount charged in this case is 95 yen + 170 yen + 221.25 yen = 486.25 yen.

  Similarly, when the maximum discount rate of the upper limit of the product when the discount rate associated with the increase in the number of purchased products is set as P, the product is designated as the Nth point (where N is 2 or more). (Integer) The discount rate (discount) of the Nth product when purchasing (adding to cart) is

It can be expressed.

  However, the discount addition ratio M is an arbitrary number of 1 or more. As can be understood from the above [Equation 9], when purchasing a plurality of different products, the N-th discount rate increases to the upper limit discount setting P for the N-th product as the number N of purchases increases. On the other hand, P will not be exceeded. Therefore, by setting P to a value that is not cheaper than the cost of the product, it is possible to set a discount rate that increases in accordance with the number of purchases while securing a minimum profit. In addition, the calculated amount of 1 yen or less in the final total invoiced amount may be adjusted in practice by rounding down, rounding up, or rounding off as appropriate. The values of P and M in the above [Equation 9] can be set in consideration of the cost and the like for each product type.

(Third embodiment)
FIG. 3 is a conceptual diagram for explaining a discount rate setting method when the same purchaser X1000 purchases different products C1400, products A1200, and products B1300 with different discount rates. That is, it is the case where the purchase merchandise content is the same as in the case of the second embodiment, but the purchase order (or the order to put in the cart) is different.

  For example, as shown in FIG. 3, the purchaser X1000 purchases a cart 1500 with a product C1400 with a discount of c%, a product A1200 with a discount a%, and a product B1300 with a discount b% one by one in this order. First, a discount rate of c% is applied to one product C1400 put in the cart first. For example, when the product C1400 is a brush case with a unit price of 300 yen and a discount of 15%, the price after applying the discount is 255 yen.

  Next, with respect to one product A1200 put in the cart, the second discount rate when two products A1200 are purchased is applied. That is, if the example of the first embodiment is used,

It becomes.

  That is, if a = 5, it can be calculated as 7.5%. More specifically, if the eraser price of the product A1200 (for example, the regular price) is 100 yen, the selling price is 92.5 yen minus 7.5% discount. That is, although there is only one eraser actually put in the cart, since the product purchased by the same purchaser X1000 is the second item, the discount setting for the eraser is calculated using two erasers. When purchasing, a discount is set for the second eraser.

  Similarly, with respect to one product B1300 that is put in the cart as the third product for purchase by the purchaser X1000, the discount rate of the third product when purchasing three products B1300 is applied. . That is, if the example of the first embodiment is used,

It becomes.

  That is, if b = 10%, the discount rate when buying two of them is 15%, so that it can be calculated as 17.5% by substituting this into [Equation 11]. More specifically, if the price without discount (for example, the regular price) of the product B1300 is 200 yen, the selling price is 165 yen minus 17.5% discount. That is, although there is only one sharpen actually put in the cart, the same purchaser X1000 purchases the third item as the number of items purchased. It is assumed that a discount is set for the third sharpen when purchasing three sharpens. Accordingly, the total amount charged in this case is 255 yen + 92.5 yen + 165 yen = 512.5 yen.

  Similarly, when the maximum discount rate of the upper limit of the product when the discount rate associated with the increase in the number of purchased products is set as P, the product is designated as the Nth point (where N is 2 or more). (Integer) The discount rate (discount) of the Nth product when purchasing (or adding to cart)

It can be expressed.

  However, the discount addition ratio M is an arbitrary number of 1 or more. As can be understood from the above [Equation 12], when purchasing a plurality of different products, the N-th discount rate approaches the upper limit discount setting P for the N-th product as the number N of purchases increases. On the other hand, P is not exceeded. Therefore, by setting P to a value that is not cheaper than the cost, it is possible to set a discount rate that increases in accordance with the number of purchases while ensuring a minimum profit. In addition, the calculated amount of 1 yen or less in the final total invoiced amount may be adjusted by rounding off, rounding up, or rounding off as appropriate in practice. In the first embodiment, the second embodiment, and the third embodiment, as a typical example of the upper limit discount setting P, double the discount rate of one product (example: P = a% × 2) is set. It is described as having been done.

(Fourth embodiment)
As can be understood from the second embodiment and the third embodiment described above, when purchasing a plurality of different products, the unit price of each product and the discount rate per product, which are the basis of calculation, are different for each product. Because of the difference, the calculation criteria for the point that the product hits differ depending on the order of putting them into the cart. Therefore, even if the total purchase merchandise content is the same, the total payment amount (total amount charged) differs depending on the calculation order of the number of purchases to be calculated.

  Actually, in the description of the second embodiment and the third embodiment, the total purchase product is the same for each purchase of an eraser, a pencil, and a brush case, and each product unit price and single discount rate are the same. Nevertheless, the total purchase amount (total amount charged) is calculated as different. For this reason, for example, when shopping in an online shop or the like, a cheapest calculation result may be presented by providing a dedicated icon or the like and clicking it. Further, in an actual store or the like, a cash register or a calculation device (information processing device (personal computer, POS system, etc.)) may be configured so as to be charged with the cheapest calculation result. Thereby, it becomes possible to always charge the customer for the same purchase merchandise content at the same minimum calculated price.

  FIG. 5 is a flowchart for explaining a typical example of a processing procedure for determining and charging a final purchase amount (billing amount) for a purchaser when purchasing a plurality of products and services according to the present embodiment. Therefore, procedures and processes will be described below based on the steps in FIG.

(Step S510)
First, it is determined whether or not there are a plurality of products or services that the purchaser intends to purchase. If there are not a plurality of items, the sales price can be calculated by applying the discount rate per product for the purchase as it is. If there are a plurality of products or services that the purchaser intends to purchase, the process proceeds to step S520.

(Step S520)
Based on [Equation 12] described above, a discount rate for each product / service is calculated and applied, and individual sales prices are determined for all the products, etc. to be purchased (in the cart). As the upper limit discount setting P and the discount addition ratio M in [Equation 12], values predetermined in advance for each product / service can be used.

  In addition, the upper limit discount setting P and the discount addition ratio M use values that are preferentially set for each customer in accordance with the customer's past purchase record and the cumulative number of points given in accordance with the purchase record. Also good. For example, the customer X whose purchase price for the past month at the store is 100,000 yen is set to a smaller M (for example, M = 1.8), and the purchase price for the past month is 10,000 yen. For customer Y, M may be set to a larger value (for example, M = 2.2), and such setting is based on data such as points (point cards and point data) possessed by the customer. Can be set. Further, the upper limit discount setting P and the discount addition ratio M may be appropriately set for each purchaser according to the degree of contribution or evaluation of the purchaser to the seller. For example, for purchasers who contributed to advertisements / advertising by uploading / introducing the seller's products, etc. on the purchaser's homepage, SNS, etc. M may be set to a smaller value (for example, M = 1.5) (that is, (1 / M) becomes larger, so the discount rate is likely to increase according to the number of purchased items).

(Step S530)
Next, a total purchase price is calculated by adding together the first product / service and all the amounts for each product / service calculated in step S520.

(Step S540)
As already described, even if the purchase combination contents of a plurality of products / services are the same, the discount rate and discounted price of each product calculated in step 520 are arranged in the order of placing them in the cart (that is, what number, what number product) Depending on the order of purchase, etc.). For this reason, for example, the charge price may be different even for the same product depending on the order in which the product is sent to the cash register or the order in which the product is put into the cart at the net shop. In order to avoid such a situation, the total amount in step S530 is calculated for all arrangement variations, and then the total amount is compared, and the total amount with the lowest price is set as the final billed amount. preferable. As a result, the purchaser can further enjoy a sense of value.

(Step S550)
It is determined whether or not the purchaser has clicked on the icon. If so, the process proceeds to step S560. In the case of cash registering, a cash register operator may press the cash register total button instead of an icon.

(Step S560)
In a net shop or the like, the lowest price in step S540 can be displayed as a billed amount by clicking the corresponding icon, for example, according to the terminal operation of the purchaser.

  Each step as shown in FIG. 5 can be calculated by a server or the like on the virtual store side, and the result can be displayed on the customer terminal of the net purchaser. It may be displayed on the cash register, or may be calculated by a CPU or the like provided at the cash register or POS of the actual store and displayed on the cashier or presented to the purchaser. In addition, use computers and various information processing devices to determine the prices of the above-mentioned products, calculate the total amount charged, select the lowest total amount, and display / present it on a display device, monitor, etc. can do.

  The discount rate setting method and the discount rate setting system described in the above-described embodiment are not limited to the individual description in the embodiment, and can be freely set within the scope of the technical idea of the present invention and within the obvious range. It is possible to change the configuration and calculation method, arrange them, and apply them in combination. Furthermore, the above-described method can be applied and used in wholesale trade, retail trade, convenience stores, supermarkets, net shops, mass retailers, virtual currencies, block chains, and the like.

  The present invention is suitable as a discount rate setting method and a discount rate setting method system.
