k) and the like may be used.

The system 50 is also connected to the POS (Point of Sales) management center 20 of the seller via the dedicated line 30, and acquires sales price information from the POS management center 20. The POS management center 20 stores 22 to 26
In addition to managing sales prices collectively or for each store, sales information from each store is acquired and totaled as appropriate. Note that a plurality of sellers may be connected to the system 50, and in such a case, a plurality of computers similar to the POS management center 20 are connected to the system.

In the present system 50, the customer purchase history D
B4 stores a purchase history for each customer. FIG. 2 shows customer 1
FIG. 4 is a diagram showing a structure of a purchase history (file) of the present invention. In this figure, a plurality of fields F1 to F5 are provided in the purchase history file 4a, a "purchase time" in the field F1, a "purchase store" in F2, a "purchase item" in F3, and a F
4 stores the “manufacturer (maker)” of the purchased product, and F5 stores the “purchase price”. The purchase history file 4a includes a plurality of records 40, 41, 42, 43,.

In this example, purchase histories at a plurality of stores (or sellers such as XX supermarkets and XX markets) are recorded in a file for each customer. May be created. This is because, when a customer pays by card at the time of purchase, it is usually managed for each store (or for each seller).

The sales price information DB 6 stores the sales price of each product. FIG. 3 is a diagram illustrating a configuration of a selling price (file) of a product “3 pieces of sashimi”. In this figure,
The sales price file 6a is stored in the store (○ × Super XX

3 stores “customer price” for each record. Here, the standard price is a selling price for a normal customer, and the good customer price is a selling price for a customer (good customer) who has purchased over a predetermined purchase price. That is, the selling prices are ranked. Note that records 61, 62, and 63 are obtained by dividing the business hours from opening to closing on a certain day as sales dates into three time zones.
This is data that records the standard price and the customer price in each time zone. In this example, a good customer can purchase a product at a lower price than a normal customer, and the price decreases as the time zone approaches the closing time.

The customer information DB 10 stores an e-mail address for each customer in order to transmit an advertisement to be described later to the customer terminals 70 and 72 by e-mail. Also, the address, contact information, attribute information, and the like of the customer are stored as appropriate. The questionnaire template 12 stores a format used when a questionnaire described later is transmitted to the customer terminals 70 and 72 by e-mail.

Next, a processing flow performed by the control means 2 of the present system based on the purchase history stored in the customer purchase history DB 4 will be described with reference to FIGS.

FIG. 4 is a flowchart for generating and distributing a predetermined advertisement according to the past purchase amount of the customer. In this figure, first, the control unit 2 determines a product to be delivered an advertisement (step S200). The determination of the product to be advertised may be specified from, for example, the store (seller) that is the advertisement distribution source. In the following description, "store (seller)"
In addition to individual stores like reference numerals 22 to 26 in FIG. 1, when each store is a chain store, they may be combined. Similarly, the “sale price” may be the price for each individual store, or may be the same price when each chain store sells at the same price.

Next, the control means 2 acquires from the purchase history the amount that the target customer has previously purchased at the store (seller) (step S202). Note that the past purchase amount may be, for example, the total purchase amount within a predetermined period from the current time. Then, the control unit 2 acquires the selling price of the product determined in step S200 from the selling price information DB6.
(Step S204). Here, as shown in FIG. 3, the sales prices recorded in the sales price file are ranked according to the purchase amount of the customer, and the control means 2
The purchase price obtained in step S202 is compared with the ranking of the sales price file, and a different sales price is obtained for each individual customer. In FIG. 3, a predetermined purchase price is set as a threshold, and two ranks of “standard price” and “good customer price” are ranked before and after the threshold. However, the present invention is not limited to this.

Further, the control means 2 determines in step S204
Generates an advertisement containing the sales price of the product obtained in (e.g., "Today, product XX is $ 2") as an email
(Step S206), the e-mail is transmitted with the e-mail address of the customer recorded in the customer information DB 10 as a transmission destination (Step S208). The customer browses the e-mail and purchases advertising products as needed. To purchase at the price indicated in the e-mail, an e-mail screen may be presented to the clerk at the store. When the customer terminal is a fixed terminal such as a personal computer, a predetermined keyword or the like included in the e-mail may be declared at the store and purchased.

As described above, since an advertisement of a product is made at a lower price to a customer who has purchased a large amount in the store in the past, a purchase incentive at the store works for the customer, which is advantageous for the store. .

FIG. 5 is a flowchart for generating and distributing an advertisement according to the purchase type of a customer. In this figure,
First, the control unit 2 determines a purchase type (trend) of a product purchased by a customer at a predetermined store from a purchase history of each customer.
(Step S220). Here, the purchase type refers to a product classified into a predetermined type (for example, daily necessities, fresh foods, living goods, and the like), and the above-described determination is made depending on which type of product is purchased most. For example, a threshold may be set for the purchase amount for each type, and it may be determined that the purchase amount is large for the types exceeding the threshold.

Next, the control unit 2 acquires, from the sales price information DB, the sales prices of the products belonging to the type determined to have a large purchase price in step S220 among the products to be advertised (step S222). Here, it is assumed that a product to be advertised is associated with the purchase type in advance.
Further, similarly to step S204, a ranked price may be acquired. The product to be advertised is determined in advance in the same manner as in step S200.

Then, the control means 2 determines in step S20
6. In the same manner as in S208, an advertisement including the sales price of the obtained product (for example, “Today, product XX is $ ¥”) is generated as an e-mail (step S224), and is sent to each customer (terminal). The data is transmitted (step S226). The customer browses the e-mail and purchases the product as appropriate.

As described above, since the advertisement of the corresponding product is performed in accordance with the type of the purchase at the store in the past, the product which is highly likely to be purchased by the customer can be advertised, and the advertisement effect becomes large.

FIG. 6 is a flowchart for generating an advertisement by predicting the next purchase time for a specific product and distributing the advertisement. In this figure, first, the control unit 2 acquires the time when the customer purchased a specific product at a predetermined store from the purchase history (step S240). Here, a specific product is used regularly by customers, such as seasonings and detergents,
It refers to a product purchased by a customer at almost constant intervals.

Next, the control means 2 predicts the time when each customer will next purchase a specific product from the purchase time acquired in step S240 (step S242). This prediction is
For example, if you buy a particular product about every three months,
This is performed by regarding the next purchase time of this customer as three months after the previous purchase. Then, the control unit 2 acquires the selling price of the specific product from the selling price information DB at a predetermined point in time near the next purchase time (step S246).

Further, the control means 2 determines in step S20
6. In the same manner as in S208, an advertisement including the sales price of the acquired product (for example, "It is time to purchase the product XX.
Is generated as an e-mail (step S246) and transmitted to each customer (step S24).
8). The customer browses the e-mail and purchases the product as appropriate.

As described above, the advertisement is delivered at the time when the next purchase time is approaching for a specific product such as a seasoning or a detergent, which is purchased by the customer at a substantially constant time, so that the advertisement effect is large. In addition, there is an advantage that a customer is prevented from forgetting to purchase a specific product.

It is to be noted that, in place of the specific product, the past visit time of the customer can be acquired from the purchase history, and the next visit time of the customer can be predicted. The processing flow in this case is also the same as described above. Then, an advertisement including a selling price of a predetermined product may be delivered at a time before the predicted visit time.

In this way, the advertisement is delivered when the expected next customer visit time comes, so that the advertisement effect is large.

FIG. 7 is a flowchart of a process for preventing a product purchased recently by a customer from being included in an advertisement. In this figure, first, the control unit 2 acquires, from a purchase history of each customer, a product purchased by the customer at a predetermined store from a point in time when the advertisement is distributed to a certain period before (step S260). next,
The control unit 2 executes step S26 of the advertisement target product.
The sales prices of the other products except the product obtained at 0 are obtained from the sales price information DB (step S262). The product to be advertised is determined in advance in the same manner as in step S200.

Then, the control means 2 determines in step S20
6. In the same manner as in S208, an advertisement including the selling price of the acquired product (for example, “Today, product XX is $ ¥”) is generated as an e-mail (step S264) and transmitted to each customer (step S264). S266). The customer browses the e-mail and purchases the product as appropriate.

As described above, since the advertisement is not performed for the product purchased by the customer recently, the waste of browsing the advertisement of the product already purchased is eliminated for the customer,
If the price of a product fluctuates after purchase, such as a bargain,
It is possible to prevent inadvertent notification of the fact to the customer. For example, referring to the record 42 in FIG. 2 above, the customer 1 purchases three sashimi sashimi at XX supermarket XX store at 15:30 on April 1, 2001 for "980 yen". However, looking at the sales price file in FIG.
After the hour, the price drops to "698 yen". Therefore, if the price after 18:00 is advertised and delivered to the terminal of the customer 1, the customer will feel remarkable discomfort, and it is effective to prevent such trouble.

The processing flow in the case where the customer's past store visit day or daily store visit time is obtained from the purchase history instead of the already purchased product and the customer's next store visit day or store visit time is predicted as described above. The same is true. Then, the advertisement including the sales price of the predetermined product may be distributed on any day except the predicted store visit day or at any time except the predicted store visit time.

In this way, the advertisement is delivered on a day different from the day on which the customer always purchases, so that the customer's purchase frequency can be increased.

Next, the second invention of the present invention will be described. The first invention described above distributes a predetermined advertisement from the present system 50 to the customer terminals 70 and 72, but the second invention described below is based on a request from a questionnaire client (usually a seller or a maker (manufacturer) of a product). It is characterized in that the content of the completed questionnaire is transmitted to the terminal of the customer, and the answer result is classified by a predetermined method.

The second invention of the present invention is performed according to the flow shown in FIG. In this figure, it is assumed that first, a questionnaire requester in advance has designated a product of a specific item from a questionnaire requester. Here, the “item” refers to a product having the same type of product, for example, “soy sauce”.
For example, this corresponds to a case where a questionnaire is requested from a soy sauce maker to a customer who has purchased “soy sauce” of each company.

Next, the control means 2 of the system 50 extracts the customer who purchased the product of this item from the customer purchase history DB 4 (step S400). In this process, extraction is performed irrespective of the purchase store and the manufacturer of the product. Then, the control means 2 generates a predetermined questionnaire as an e-mail in accordance with the format recorded in the questionnaire template 12, and transmits it to the customer terminal extracted in step S400 (step S402). The questionnaire is provided with items for asking information about the product, such as the reason for purchasing the product and the impression of using the product.
Further, an item completely different from the product may be provided in order to inquire about a consumption trend or the like.

The control means 2 receives the result of the questionnaire from the customer terminal as an e-mail (step S40).
4) Further, the customer is specified from the source address of the received e-mail and the like, and the purchase history of the customer is acquired from the customer purchase history DB 4 (step S406).

Then, the control means 2 acquires a list of manufacturers of the products of the specific item purchased by the customer from the purchase history (step S408). For example, in the case of the customer 1 shown in FIG. 2, the record 4 corresponding to the specific item “soy sauce”
Looking at Nos. 1 and 44, it can be seen that there are two manufacturers, “× △ company” and “XX company”.

Next, the control means 2 analyzes the distribution tendency of the manufacturer list acquired in step S408 for each customer, and classifies the answer result according to the result (step S41).
0).

FIG. 9 shows the distribution tendency of the list of manufacturers for "soy sauce".
Company "," XX company ", and" □ company ". In this figure, the customer 1 is “× △ company” and “XX company”
Indicates a distribution tendency of purchasing once, and in this case, it is classified as “intermediate type”. Further, the customer 2 purchases “× △ company” most (5 times) and is classified as “×「 company type ”. Similarly, for customer 3, "□ company" is the most (3 times)
Purchased and classified as “□ company type”. Then, the answer result for each customer is classified according to these classification patterns.

Then, the control means 2 transmits the classified answer result to the terminal of the questionnaire client (step S41).
2).

As described above, the customer who has purchased the product of the specific item is requested to respond to the questionnaire, and the response result is classified according to the distribution tendency of the manufacturer who purchased the specific product. Information can be extracted.

Next, the third invention of the present invention will be described. This invention also transmits the contents of a questionnaire requested by a questionnaire requester to a customer terminal.

The third invention of the present invention is performed according to the flow shown in FIG. In the figure, it is assumed that a questionnaire requester first specifies a product name and its manufacturer in advance by a questionnaire requester.

Next, the control means 2 of the present system 50 extracts from the customer purchase history DB 4 the customers who have purchased the goods whose manufacturer is specified (step S500). And
The control means 2 generates a predetermined questionnaire as an e-mail in accordance with the format recorded in the questionnaire template 12, and transmits it to the customer terminal extracted in step S500 (step S502).

The control means 2 receives the result of the questionnaire from the customer terminal as an e-mail (step S50).
4), send it to the terminal of the questionnaire client (step S
506).

As described above, based on the customer purchase history database, a customer who has purchased a product of a specific manufacturer is requested to respond to a questionnaire, and the response result is obtained. By investigating the tastes and the like of the customers who make purchases, meaningful information can be obtained.
