Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product information providing system, a product information providing apparatus and method, a recording medium, and a program, and particularly, to a seller at an appropriate product price in which supply and demand are well balanced. The present invention relates to a merchandise information providing system, a merchandise information providing apparatus and method, a recording medium, and a program that enable a user to perform a commercial transaction.

[0002]

2. Description of the Related Art Conventional commercial transactions are mainly conducted in stores. That is, the user goes to the store, pays the price directly to the seller in the store, and purchases the product displayed in the store. In addition, commercial transactions such as mail-order sales and electronic shopping via networks have become popular in recent years.

Further, the selling prices of the products in these commercial transactions are set mainly based on the business plan and sales plan of the seller.

[0004]

In other words, since the selling prices of the products in these commercial transactions are set by the logic on the seller side, they are often prices that do not match the desired purchase price of the user. is there. When a commercial transaction is carried out at an improper price setting where the supply and demand are not balanced, there is a problem that the product inventory increases on the seller side. On the other hand, there is a problem on the user side that it becomes difficult to purchase a product at a desired purchase price.

For this reason, in general, a bargain sale is carried out for the purpose of reducing the product inventory. The sale price of the product in the bargain sale, so-called bargain price, is set to a price lower than the price that has been sold so far. However, this bargain price is still set by the logic of the seller. For this reason, it is rare that the bargain price is an appropriate price that balances supply and demand. As a result, even if the product inventory can be reduced, the product inventory desired by the seller cannot be reduced depending on the supply and demand balance (time, qualitatively, or quantitatively) with the user. is there.

That is, in the conventional commercial transaction, there is a problem that it is difficult to conduct the commercial transaction with an appropriate price setting in which supply and demand are well balanced.

[0007] Further, as an additional problem of the conventional product transaction, there is a problem that the price of the product cannot be properly transmitted from the seller to the user. For example, the user often does not know that the bargain sale is being performed because the target to which the leaflet of the bargain is distributed is too narrow or the user happens to not see the leaflet of the bargain. In this case, even if the bargain price is a proper price, the user does not know the proper price, so the user cannot purchase the product. As a result, similar to the above-mentioned price setting problem, there is a problem that the product inventory increases on the seller side. Further, there is a problem that the user cannot purchase the product at the desired purchase price.

[0008] Therefore, an object of the present invention is to appropriately convey to a user an appropriate product price in which supply and demand are balanced, and to enable a seller and a user to conduct a commercial transaction at an appropriate product price. Especially.

Further, a product information providing device 14 is connected to the network 11.

FIG. 2 shows a configuration example of the product information providing device 14.

In FIG. 2, a CPU (Central Processing)
Unit) 21 is a program stored in ROM (Read Only Memory) 22 or RAM (Ran
Various kinds of processing are executed according to the program loaded in the dom access memory) 23. RAM23 also has a CPU
Data and the like necessary for the 21 to execute various processes are also stored as appropriate.

The CPU 21, ROM 22 and RAM 23 are connected to each other via a bus 24. An input / output interface 25 is also connected to the bus 24.

The input / output interface 25 includes an input unit 26 including a keyboard and a mouse, a display including a CRT and an LCD, an output unit 27 including a speaker, and a storage unit 28 including a hard disk.
A communication unit 29 including a modem and a terminal adapter is connected. The communication unit 29 uses the network 1
The communication processing via 1 is performed.

A drive 30 is connected to the input / output interface 25 as required, and a magnetic disk 41,
The optical disc 42, the magneto-optical disc 43, the semiconductor memory 44, or the like is appropriately mounted, and the computer program read from them is installed in the storage unit 28 as necessary.

Although not shown, the user terminal 12
The items a to 12c and the product seller terminal 13 are basically configured similarly to the product information providing device 14. In the following description, FIG. 2 is also cited as the configuration of the user terminals 12 a to 12 c and the product seller terminal 13.

Next, the operation of the product information providing system of FIG. 1 will be described with reference to the flowcharts of FIGS. FIG. 3 shows processing of the product seller terminal 13. FIG. 4 shows the processing of the product information providing device 14. FIG. 5 shows processing of the user terminals 12a to 12c. FIG. 6 shows the processing relationship of the product seller terminal 13, the product information providing device 14, and the user terminals 12a to 12c.

The processing of the product information providing device 14, the product seller terminal 13, and the user terminals 12a to 12c will be individually described below with reference to FIGS.
The mutual processing relationship of these devices can be easily understood by referring to the corresponding steps in FIG.

First, the processing of the product seller terminal 13 will be described with reference to FIG. The user terminal 12
The processes corresponding to the processes a to 12c and the product information providing device 14 will be described with reference to FIG.

When there is a product that the seller wants to sell, the seller sells the sales condition to the input unit 26 of the seller terminal 13.
Operate and input.

In step S41, the input sales conditions are converted into sales condition data by the CPU 21.

Now, the product seller sells "short-sleeved shirts". Further, in the case of this example, the selling condition is “market price”. Here, the product price that fluctuates as the value of the product fluctuates is called the “market price”. This market price is
Generally, it is a product price applied to a seasonal product, such as the “short-sleeved shirt” of this example, whose product value is expected to drop after a certain period of time. The market price of the short-sleeved shirt in this example is determined based on the line 101 representing the product price, as shown in FIG. 7. That is, the market price of the short-sleeved shirt is calculated by substituting a specific date and time into a predetermined time function. Details of FIG. 7 will be described later.

Therefore, the sales condition data of this example is "the formula of the time function for calculating the market value of the short-sleeved shirt (line 10
1 is a data of time function formula) ”.

When the time function for calculating the market price is recorded in advance in the product information providing device 14,
The sale condition data may be only the “short-sleeved shirt sale price (10,000 yen in this example)”. That is, the merchandise information providing device 14 may calculate the “market price of the short-sleeved shirt” by substituting the “selling price of the short-sleeved shirt” of this sales condition into the pre-recorded time function.

In step S41, the CPU 21 sends the sales condition data to the merchandise information providing device 14.
It is transmitted from the communication unit 29. The product information providing device 14 is
As will be described later, this sales condition is compared with the purchase condition for purchasing the product presented by the user corresponding to this sales condition data, and if the result of the comparison is evaluated to satisfy a predetermined judgment criterion, the product is Sends information data (Fig. 4
And step S57 in FIG. 6).

Therefore, in step S42, the CPU 2
1 is a product information providing device 1 via a network 11.
The merchandise information data transmitted from No. 4 is received by the communication unit 29 and recorded in the storage unit 28.

The merchandise information data includes a message that "sales conditions for short-sleeved shirt (market price of short-sleeved shirt) matches purchase conditions of user", "sales price for short-sleeved shirt",
It contains the "user ID" used for the purchaser verification, which will be described later.

The merchandise information data is the user terminal that has transmitted the purchase conditions that match the sales conditions, for example, the user terminal 12.
When the purchase information data for requesting the purchase of the product is output from the user terminal 12a based on it, the purchase information data is sent from the product information providing device 14.
It is relayed and transmitted (step S5 in FIGS. 4 and 6).
9).

Therefore, in step S43, the CPU 2
1 is a product information providing device 1 via a network 11.
The communication unit 29 receives the purchase information data transmitted from the communication unit 4.

This purchase information data includes a message "user wants to purchase short-sleeved shirt under purchase conditions" and "user ID".

In step S44, the CPU 21 reads the "user ID" from the received purchase information data and determines whether this "user ID" is the ID of the authorized purchaser. That is, each user who uses this system,
Register yourself in the product information providing device 14 in advance,
Has been assigned an ID. CPU21 is "user ID"
It is determined whether the ID is the ID stored in the storage unit 28 in step S43. Note that this determination is referred to as purchaser verification here. When it is determined that the ID is the authorized purchaser's ID, in this example, the CPU 21 "passes".
And the contents of "Specific purchase method of short-sleeved shirt" and the like. Here, this generated data is referred to as purchaser verification result data.

On the other hand, when it is determined that the ID is not the ID of the authorized purchaser, the CPU 21 generates data including the contents of "fail" and "reason for failure". This generated data is also called purchaser verification result data.

In step S45, the CPU 21 causes the communication section 29 to transmit the purchaser verification result data to the user terminal 12a. This transmitted purchaser verification result data is stored in the user terminal (in this case, the user terminal 12
According to a), it is received in step S75.

Next, the processing of the product information providing device 14 will be described with reference to FIG. The user terminal 12a
12 to 12c and the processing corresponding to the processing of the product seller terminal 13 will be described with reference to FIG.

In step S51, the CPU 21 of the product information providing device 14 sends the sales condition data (data transmitted in the process of step S41) transmitted from the product seller terminal 13 via the network 11 to the communication unit. Two
9 to receive.

In step S52, the CPU 21 records the received sales condition data in the storage unit 28.

In this example, as described above, the sales condition data of the "time function formula for calculating the market price of the short-sleeved shirt (time function formula for creating the line 101 for determining the commodity price)" is recorded. It

In step S53, the CPU 21 sends the user terminals 12a to 12c via the network 11.
Arbitrary one (in the example of FIG. 6, the user terminal 12a)
When the purchase condition data is transmitted from, the communication unit 29 receives it.

Then, in step S54, the CPU 2
1 causes the storage unit 28 to record the received purchase condition data.

The purchase condition data of this example is the desired purchase price data of the short-sleeved shirt. More specifically, "user A (user terminal 12a): 8000 yen", "user B (user terminal 12b): 7,000 yen", "user C"
(User terminal 12c): 500 yen ", which is a condition presented for each user to purchase a product.

Next, in step S55, the CPU 21
Reads the sales condition data recorded in the process of step S55 and the purchase condition data of each user recorded in the process of step S54 from the storage unit 28, and reads out the sales condition data and the read out purchases. Compare the condition data.

When the read sales condition data is data that cannot be compared as it is, the CPU 21 appropriately converts the read sales condition data into data suitable for comparison. For example, when the read sales condition data is data of “time function formula for calculating market value (time function formula for creating the line 101)”, the CPU 21 adds the current year to the formula. By inputting the date information, it is converted into data of “current (comparison point) market price of short-sleeved shirt” by.

Then, in step S56, the CPU 2
1 evaluates the result of the condition comparison based on a predetermined criterion.

The data of this judgment standard is recorded in the storage unit 28 in advance, and when this evaluation is performed, the CP
Read by U21. The determination criterion in this example is, for example, "the user's desired purchase price (purchase condition) is equal to or higher than the market price (sale condition) of the short sleeve shirt".

When the result of the comparison of the conditions is evaluated as not satisfying the criterion (when NO is determined in step S56), the CPU 21 performs the time counting operation in step 60, and it is determined that the predetermined time has passed. If it is determined, the process returns to step S55. Then, the CPU 21 calculates the sales condition on that date and compares it with the purchase condition.

In step S56, the result of the condition comparison is
If it is evaluated that the determination criteria are satisfied (YES in step S56), in step S57,
The CPU 21 generates product information data. This product information data includes a message indicating "the user ID of the user (user terminal 12) who has sent the purchase condition that matches the sale condition", "the selling price", and "the purchase condition and the sale condition match". include. The generated merchandise information data is transmitted via the communication unit 29 to the user terminal and the merchandise seller terminal 13 that have transmitted the purchase conditions that match the judgment criteria. The transmitted data is received by the product seller terminal 13 in step S42 as described above, and is also received by the user terminal 12 in step S72 as described later.

In the example of FIG. 7, when the selling price is calculated as of June, the "market price of the short-sleeved shirt" is "8000.
It becomes a "yen". Then, when comparing the sales conditions with the purchase conditions of each user, the only purchase condition that satisfies the criterion, that is, "the user's desired purchase price is 8000 yen or more" is "User A: 8000 yen". Become. That is, the user terminal 12a used by the user A is the only user terminal that has transmitted the purchase condition data that matches the determination criteria. So, "The short-sleeved shirt has a market price of 8
Since it has reached 000 yen, you can purchase a short-sleeved shirt for 8,000 yen. Your user ID is ... The product information data including the contents such as "is transmitted to the user terminal 12a and the product seller terminal 13. Note that the user terminal 12b and the user terminal 12c whose purchase conditions do not match the sales conditions.
Nothing is sent to.

When the fixed time of step S60 in this example is "1 month", the evaluation of the comparison of conditions is performed again in July when 1 month has passed from this evaluation process. In the example of FIG. 7, since the selling condition as of July is “the short-sleeved shirt has a market price of 7,000 yen”, the user who has sent the purchase condition that matches the determination criteria is the user A (the desired purchase price 80
00 yen) and user B (desired purchase price 7,000 yen). Therefore, similar product information data is transmitted to the user terminal 12b used by the user B. In this example, since the product information data is transmitted to the user terminal 12 only once, the product information data is not transmitted to the user terminal 12a used by the user A as of July. .

It is to be noted that it is confirmed whether or not the user A has already purchased the short-sleeved shirt.
A setting condition for retransmitting the product information data as of the month may be added to the product information providing device 14.

Purchase information data is transmitted from the user terminal 12 in response to the product information data transmitted in the process of step S57 (step S74 of FIGS. 5 and 6).

Therefore, in step S58, the CPU 2
1 is a user terminal 12a via the network 11,
Alternatively, when the purchase information data is transmitted from 12b, the communication unit 29 receives it.

Then, in step S59, the CPU 2
1 is the product seller terminal 1 that receives the purchase information data.
3 is transmitted by the communication unit 29 and relayed. As described above, the transmitted purchase information data is received by the product seller terminal 13 in step S43.

Next, of the processes of the user terminals 12a to 12c, the process of the user terminal 12a of the user A will be described with reference to FIG. Since the processes of the user terminals 12b and 12c are the same, the description thereof will be omitted. Further, processing corresponding to the processing of the product information providing device 14 and the product seller terminal 13 will be described with reference to FIG.

As described above, the user A is registered in the product information providing device 14 in advance, and the product information providing device 14 assigns a "user ID" unique to the user A. To do.

When the product that the user A wants to purchase is registered in the product information providing device 14 by the product seller, the user A operates the input unit 26 of the user terminal 12a to specify the purchase condition for purchasing the product. And enter.

In step S71, the input purchase conditions are converted into purchase condition data by the CPU 21. Then, the CPU 21 causes the communication unit 29 to transmit the purchase condition data to the product information providing device 14. This transmitted purchase condition data is received by the product information providing device 14 in step S53, as described above.

As described above, the purchase condition data in this example includes the message "Purchase price of short-sleeved shirt: 8000 yen" and "User ID".

As described above, the merchandise information providing device 14 compares the purchase condition received in the process of step S53 with the sale condition of the merchandise seller received in the process of step S51. When it is determined that the predetermined condition is satisfied, the product information data is transmitted (step S57 in FIGS. 4 and 6).

Therefore, in step S72, the CPU 2
1 is a product information providing device 1 via a network 11.
4 transmits the product information data sent from the communication unit 29.
To receive.

The user A looks at the message of the merchandise information data, determines whether or not to purchase the merchandise, and issues a command corresponding to the judgment from the input unit 26.

In step S73, the CPU 21 determines whether or not the purchase of the merchandise is designated based on the input from the input unit 26.

When the purchase of the product is not designated (NO in step S73), the CPU 21 ends the process of the user terminal 12a.

If it is determined that the purchase of the product has been designated (YES in step S73), user A
Operates the input unit 26 to input purchase information requesting the purchase of the product.

In step S74, the CPU 21 converts the purchase information into purchase information data, and causes the communication section 29 to transmit the purchase information data to the product information providing device 14. The transmitted purchase condition data is relayed by the product information providing device 14 in the processing of step S58 and step S59 as described above, and then step S4.
It is received by the product seller terminal 13 in the process of 3.

This purchase information data is, as described above,
The message includes "the user wants to purchase a short-sleeved shirt under the purchase conditions" and "user ID".

The purchaser verification result is transmitted from the seller terminal 13 of the seller corresponding to the purchase information data transmitted in the processing of step S74 (steps S in FIGS. 3 and 6).
45).

Therefore, in step S75, the CPU 2
1 is a product seller terminal 13 via the network 11.
The purchaser verification result data transmitted from the communication unit 2
9 to receive.

In step S76, the CPU 21 determines whether or not the received buyer verification result data includes the content of "fail", and if it is determined to be included (NO in step S76). If), step S74
Return to and send the purchase information data again.

In step S76, it is determined whether or not the content of "pass" is included in the received purchaser verification result data, and if it is determined that it is included (in step S76)
If YES is determined), the process of the user terminal 12a ends. As a result, the user A is
Products can be purchased at the desired purchase price. In this example, the user A can purchase a short-sleeved shirt for 8,000 yen.

As described above, the user is provided with the merchandise information providing device 1 by using the “desired purchase price of the short-sleeved shirt” as the purchase condition.
4 and the purchase condition matches the “market price of the short-sleeved shirt” that is the sale condition of the product seller, the product including the message “The purchase condition matches the sale condition” from the product information providing device 14. The information data is transmitted to the user terminal that has transmitted the purchase condition that matches the sale condition.
As a result, the user and the product seller can carry out a commercial transaction for the short-sleeved shirt at an appropriate price that balances supply and demand.

As a result, the number of products in stock in short-sleeved shirt commercial transactions is as shown by the line 102 in FIG.

FIG. 7 shows an example of temporal changes in the product price and the product inventory number in the commercial transaction of the short-sleeved shirt to which the product information providing system shown in FIG. 1 is applied. The first vertical axis on the left side of the figure represents the product price,
The unit is yen. The second vertical axis shown on the right side of the drawing represents the number of products in stock, and the unit is a sheet. The horizontal axis represents time,
The unit is the month.

As described above, the line 101 is the “product price” when the product seller sells the short-sleeved shirt by applying the product information providing system shown in FIG. 1, that is, the “market price of the short-sleeved shirt”. Represents the transition of.

Then, the line 102 is along the line 101,
It shows the transition of the "product inventory" when a product seller sells short-sleeved shirts.

On the other hand, line 10 shown for comparison.
3 is the “commodity price” of conventional short-sleeved shirts in commercial transactions
Represents the transition of.

That is, in this example, the product seller is
From May to September, short-sleeved shirts will be sold at a fixed price of 10,000 yen, and as of September, a bargain sale will be held and the price (bargain price) will be reduced to 5000 yen. It means that it was sold until November. The product price of 0 yen means that the sale of short-sleeved shirts has been discontinued.

And line 1 shown for comparison.
A line 04 represents the transition of the "item inventory" when the item seller sells the short-sleeved shirt along the line 103.

As shown by the line 103 in FIG. 7, when a short-sleeved shirt is sold in a conventional commercial transaction, the selling price from May to September is a fixed price of 10,000 yen.
As a result, the purchase condition is "Purchase price of short-sleeved shirt: 1
Only a user who is “0000 yen or more” can purchase a short-sleeved shirt. That is, a user who has a purchase condition of “desired purchase price of a short-sleeved shirt: less than 10,000 yen” cannot purchase a short-sleeved shirt.

On the other hand, when the merchandise information providing system shown in FIG. 1 is applied and short-sleeved shirts are sold, the selling price from May to September is "market price" as described above.
Becomes

That is, as indicated by the line 101 in FIG.
The selling price as of May is 10,000 yen, similar to the selling price in conventional commercial transactions, but the selling price continues to fall in proportion to the passage of time, and the selling price as of September is 2000.
It becomes a circle. As a result, as of September, all users whose purchase condition is “Purchase price of short-sleeved shirt: 2000 yen or more” can purchase the short-sleeved shirt.

As described above, if the product information providing system shown in FIG. 1 is applied, the product seller sells the short-sleeved shirt to more users as compared with the conventional commercial transaction of the short-sleeved shirt. can do.

That is, as shown by the lines 102 and 104 in FIG. 7, if the product information providing system shown in FIG. 1 is applied, the product seller can compare the stock of goods as of September with the conventional commercial transaction. It is possible to make the number smaller than the number of products in stock as of September.

Further, as of September, the merchandise seller sets a price in consideration of each user's “purchase conditions” recorded in the merchandise information providing device 14, that is, each user's “purchased desired price”. By sending this to the product information providing device 14 as a new “sales condition”, the product inventory can be further reduced.

That is, as shown by the line 101 in FIG.
The "market price" as of September is 2000 yen, but if this "market price" is reduced to "user C's desired purchase price", that is, 500 yen, the "market price" will be given to the user C (user terminal 12c). The price) has reached 500 yen ", and the user C can purchase a short-sleeved shirt. As a result, the product seller can further reduce the inventory of short-sleeved shirts.

On the other hand, in the conventional commercial transaction, even if the bargain sale is held in September, the bargain price is the price set by the merchandise seller (in this example, line 10).
As shown in 3, it is 5000 yen). At this price, user C cannot purchase a short-sleeved shirt.

3, and the processing corresponding to the processing of the product manufacturer terminal 81 will be described with reference to FIGS. 13 and 14.

When the user A wants to purchase an item,
The purchase condition is input by operating the input unit 26 of the user terminal 12a.

In step S71, the input purchase conditions are converted by the CPU 21 into purchase condition data.

The purchase condition data of this example includes "desired product for purchase", "description of desired product for purchase", "desired price for purchase",
It includes the contents of "the desired purchase quantity" and "the user's own personal information". Further, in this example, only the user A has transmitted the purchase condition.

In step S71, the CPU 21 sends the purchase condition data to the product information providing device 14.
It is transmitted from the communication unit 29. The transmitted purchase condition data is received by the product information providing device 14 in step S111, as described later.

In this example, the product information providing device 14
It is assumed that the manager of (1) starts a project for commercializing the product satisfying the purchase condition received in the process of step S111. Details of this project will be described later.

Incidentally, the processing of steps S72 to S76, that is, the processing of receiving the product information data including the message "the purchase condition of user A matches a predetermined condition" (step S72), "user A" Process of transmitting purchase information data including a message stating "I want to purchase a product" (steps S73 and S74), the user
The process of receiving the purchaser verification result data including the determination result of whether A is a regular purchaser (step S75 and step S76) is the same as the process described in the first embodiment. The description is omitted. The details of the product information data of the second embodiment will be described later.

Next, the processing of the product information providing device 14 will be described with reference to FIGS. 9 and 10. User terminal 12
The processes corresponding to the processes of a to 12c, the product seller terminal 13, and the product manufacturer terminal 81 will be described with reference to FIGS. 13 and 14.

In step S111, the CPU 21 of the merchandise information providing device 14 transmits from any one of the user terminals 12a to 12c (the user terminal 12a in the example of FIGS. 13 and 14) via the network 11. The communication unit 29 receives the purchase condition data.

As described above, the purchase condition data is as follows.
It is the purchase condition data transmitted from the user terminal 12a in the process of step S71.

Then, in step S112, the CPU
21 causes the storage unit 28 to record the received purchase condition data.

Note that here, as described above, the user
A project to commercialize products that meet the purchase conditions of A is carried out. The network 11 is the Internet.

That is, the administrator of the product information providing device 14 is
Plan a project to commercialize the received product that satisfies the purchase condition of user A. Then, the manager discloses the outline of the project to an unspecified number of people by using, for example, a home page on the Web managed by the manager himself. Then, the product seller or the product manufacturer who wants to participate in this project registers in the product information providing device 14 as a member of the project. As will be described later, the registration method transmits predetermined registration information data from each terminal used by a registration applicant to the product information providing device 14 via the network 11 (step S161 in FIG. 11 or FIG. 12). Step S181). In this example, the registration information data includes a message of "I want to register as a merchandise seller or a merchandise manufacturer (choose one of the items on the left)" and "registrant's own information". Then, with the registered members, we will continue this project.
This member handles the planning of commercialization, manufacturing and sales of planned products.

In step S113, the CPU 21
When the registration information data is transmitted from the product seller terminal 13 or the product manufacturer terminal 81 via the network 11, the communication unit 29 receives the registration information data.

In step S114, the CPU 21
It is determined whether the received registration information data is transmitted from the product seller or transmitted from the product manufacturer.

When it is determined that the registration information data is transmitted from the merchandise seller, the CPU 21 stores the received registration information data in the storage unit 28 as merchandise seller information data in step S115. Record.
This process completes the registration.

In step S116, the CPU 21
The sales consignment information data recorded in advance in the storage unit 28 is read out, and the sales consignment information data is transmitted to the product seller terminal 13 by the communication unit 29. This transmitted sales consignment information data, as described later,
It is received by the product seller terminal 13 in step S162.

The sales consignment information data of this example includes the messages "project member registration completed", "consignment of product sales", and "project details".

[0121] The merchandise seller who has received the sales consignment information data plans the merchandise with other project members based on the purchase condition of the user A, and considers the sales profit etc. in consideration of the production cost. This is called a commercialization plan.

Then, the sales condition data including these examination results is transmitted from the product seller terminal 13 to the product information providing device 14 (step S163 in FIGS. 11 and 13). The sales condition data in this example is data of “desired sales profit”.

Therefore, in step S117, the CPU
21 is a product seller terminal 1 via the network 11.
The communication unit 29 receives the sales condition data transmitted from the communication unit 3.

If it is desired to proceed while keeping this project confidential with respect to others, access restriction processing may be performed before step S117. That is, the CPU 11
When access is requested, it authenticates whether the person who requested the access is a project member, and when it is authenticated that it is a project member, it inserts the process of allowing the access. Good.

In step S118, the CPU 21
The received sales condition data is recorded in the storage unit 28.

On the other hand, if it is determined in step S114 that the registration information data is transmitted from the product manufacturer, the process proceeds to step S119.

The processing of steps S119 to S122 is as follows.
Since the processing is the same as the processing of steps S115 to S118 described above, the description thereof will be omitted. However, in this example, the manufacturing condition data received in the process of step S121 (data transmitted from the product manufacturer terminal 81 in the process of step 183) includes a plurality of “production costs with respect to the number of products manufactured (the number of products sold)”. I'm out.

Step S118 or step S122
After the processing of step S123, the CPU 21
Purchase condition data recorded in the process of step S112,
Sales condition data recorded in the process of step S118,
Alternatively, the manufacturing condition data recorded in the process of step S122 is read out, these read out conditions are compared with each other, and evaluation is performed based on a predetermined judgment standard. The criterion for this example is "Is it possible to commercialize under the purchase conditions?" The process in step S123 is
Here, it is referred to as "condition comparison / commercialization evaluation process".

Details of the "condition comparison / commercialization evaluation process" of this example are shown in FIG. Therefore, the "condition comparison / commercialization evaluation process" of this example will be described with reference to FIG.

First, in step S141, CP
The U21 confirms whether all three conditions of purchase condition, manufacturing condition, and sales condition are recorded in the storage unit 28.

If at least one condition is not recorded, the process waits until an unrecorded condition is recorded.

If all the conditions are recorded, the CPU 21 reads the recorded manufacturing condition data from the storage unit 28 in step S142. In this example, as the manufacturing condition data, each data of “production cost with respect to production number (sales number)” is read.

In step S143, the CPU 21
The recorded purchase condition data is read from the storage unit 28.
In this example, as the purchase condition data, the “purchased desired price” and the “purchased desired quantity” data are read from the recorded purchase condition data.

In step S144, the CPU 21
The read manufacturing condition data is compared with the read purchase condition data, and one production cost data suitable for the purchase condition data is selected.

In step S145, the CPU 21
The balance is calculated based on the selected production cost data, and the calculation result data is output.

Also, in step S146, the CPU 2
1 reads the recorded sales condition data from the storage unit 28. In this example, "desired sales profit" data is read as sales condition data.

In step S147, the CPU 21
The read sales condition data is compared with the output calculation result data of the balance, and evaluation is performed based on a predetermined judgment condition. The determination criterion in this example is that "if the desired sales profit is equal to or higher than the calculation result (balance) of the balance, it can be commercialized".

Returning to FIG. 9, the processing after step S123 will be described.

In step S124, the CPU 21
It is determined whether commercialization is possible. Step S12
When it is evaluated as "incommercialization impossible" in 4, the process of the product information providing device 14 is ended.

If it is evaluated in step S124 that the product can be commercialized, the CPU 21 sends the product information data to the user terminal 12 in step S125.
The communication unit 29 causes a, the product seller terminal 13, and the product manufacturer terminal 81 to transmit. The product information data in this example includes a message such as "It was possible to commercialize under the purchase condition of user A", "sale price",
It includes "sales quantity" and "delivery date".

As will be described later, the merchandise manufacturer produces only the "sales quantity" contained in the merchandise information data received in the process of step S184, and produces the produced merchandise.
Deliver to the product seller. Then, the product seller only purchases (delivered) the product, that is, step S16.
Only the product of “sales quantity” included in the product information data received in the process of No. 4 is sold to the user A at the “sales price” included in the product information data received in step S164.

Then, the user A has the "sales quantity" included in the product information data received in the process of step S72.
The product is purchased at the "selling price" included in the product information data received in the process of step S72, that is, under the purchase condition of the user A. That is, the manufacturer
Only the required amount of products can be manufactured, and the manufacturer / seller can sell only the required amount of products.

As a result, the product seller can reduce the product inventory to 0.
Can be Then, the user A can purchase the product under the purchase condition of the user A.

Since the relay processing of the purchase information data in steps S126 to S127 is the same as the processing of steps S58 to S59 of FIG. 4 which is the processing of the product information providing device 14 of the first embodiment, the processing thereof is omitted.

In step S161, the input information is converted by the CPU 21 into registration information data. Then, the CPU 21 causes the communication unit 29 to transmit the registration information data to the product information providing device 14.

As described above, the registration information data of this example includes the messages of "registration as merchandise seller" and "information of merchandise seller itself". The transmitted registration information data is received by the product information providing device 14 in step S113 as described above.

As described above, the merchandise information providing device 14 records the received registration information data as merchandise seller information data (step S115 in FIGS. 9 and 13), and sells the consignment information data to the merchandise seller. It is transmitted to the terminal 13 (step S116 in FIGS. 9 and 13). As described above, the sales consignment information data in this example includes the messages “project member registration completed”, “consignment of product sales”, and “project details”.

Therefore, in step S162, the CPU
21 causes the communication unit 29 to receive the sales consignment information data transmitted from the product information providing device 14 via the network 11.

The merchandise seller reads the message of the sales consignment information data, makes a merchandise plan, and considers the sales conditions for merchandise as described above. The sales condition in this example is “desired sales profit” as described above.
Then, the product seller operates the input unit 26 of the product seller terminal 14 to input the sales conditions.

In step S163, the CPU 21
The entered sales conditions are converted into sales condition data. Then, the CPU 21 causes the communication unit 29 to transmit the sales condition data to the product information providing device 14. The transmitted sales condition data is received by the product information providing device 14 in step S117, as described later.

The subsequent steps S165 to S1
67, that is, the process of receiving the purchase information data including the message “User A wishes to purchase the product” transmitted from the user terminal 12a (step S16).
5) The process (steps S166 and S167) of performing purchaser verification based on the received purchase information data and transmitting the result as the purchaser verification result is performed by the product seller terminal 13 of the first embodiment. Since the process is the same as the process of steps S84 to S85 in FIG. 6, detailed description thereof will be omitted.

However, in this example, step S1
At 67, the CPU 21 sends the purchaser verification result data to
In addition to the user terminal 12a, the communication unit 29 also causes the product manufacturer terminal 81 to transmit.

That is, the transmitted purchaser verification result data is received by the user terminal 12a in step S75 as described above, and as described later,
It is received by the product manufacturer terminal 81 in step S185.

Then, as will be described later, it is judged at the product manufacturer terminal 81 whether or not the content of "pass" is included in the purchaser verification result data received in the process of step S185. If it is determined that the contents are included, a product manufacturing start instruction is output (steps S186 and S187 in FIGS. 12 and 14).

After that, the product manufacturer starts the production of the product, and produces the product of "sales quantity" included in the product information data received in the process of step S184. And
As described above, the produced products are sequentially delivered from the product manufacturer to the product seller, and the product seller receives the information in step S1.
In the “sales price” included in the product information data received in the process of 64, the user A sets the product of “sales quantity” included in the product information data received in the process of step S164.
