Abstract

PROBLEM TO BE SOLVED: To support all transaction attendants so as to efficiently obtain and use information required for the evaluation of the value of an article based on their original viewpoints by automatically requesting the transmission of information required for the evaluation of the value of the article based on the viewpoint peculiar of a user, which is previously registered in a storage device. SOLUTION: In a purchaser-side system 201, the identifier of the article that the user desires to transact is inputted from an input device 2012. The identifier of information useful for the evaluation of the value of the article corresponding to the inputted identifier is retrieved from a storage device 2014. The transmission request of information corresponding to the retrieved identifier is transmitted to an exchange system 202 through a communication network 204. When information corresponding to the transmission request is received from the exchange system 202 through the communication network 204, received information is processed/analyzed by using a processing/analysis method, which is registered in the storage device 2014. A processed/analyzed result is outputted from an output device 2013.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to information trading, that is, "value evaluation using only the attribute information of the actual product without directly looking at the actual product, and trading based on the result". The present invention relates to a method and system suitable for information exchange of perishable products distributed in a wholesale market, especially low standard products.

[0002]

2. Description of the Related Art In the past, as a general rule, trading of perishable goods on the wholesale market was in-kind trading. In-kind trading refers to "evaluating the value of a commodity by directly looking at the in-kind and transacting on the spot based on the evaluation result." If this is followed, all of the fresh produce traded will have to be brought into the wholesale market once.

Originally, perishables were produced in a wide variety by many small producers, and consumers frequently purchased small amounts of many items at the nearest retail stores. In such an environment, physical transactions, in which collection and price formation are integrally performed, function extremely efficiently. However, the inefficiency of physical transactions has become a problem due to changes in the environment such as the recent increase in size and area of producers and retailers and the spread of the market. On the other hand, it has been found that "making transactions precede the flow of goods" (separation of goods) can significantly streamline the entire distribution process from the producer to the buyer. Information trading is expected to be the key to achieving this.
The information exchange of perishable products has already been tried, although the target is limited to a very small number of products, and it is expected that it will spread widely in the near future.

[0004]

The basic business flow of information trading is as follows. First, the exchange transmits the attribute information and the quantity of the product to be traded to all the qualified persons who participate in the trade. Qualified person to participate in trading,
In addition, the person who wants to participate in the transaction (trading participant) evaluates the value of the product based on the transmitted attribute information and then purchases the price and quantity (in the case of a low standard product, usually one )
Is sent to the exchange (trade processing person in charge) as a buy order.
The exchange processes the gathered buy orders to determine the price and quantity to sell for each trading participant and informs all trading participants.

By the way, in the information trade currently under trial, the target is limited to highly standardized products (highly standardized products). The reason for this is that in the case of highly standardized products, the value of the actual product can be reasonably correctly estimated with only a small amount of common attribute information such as the place of origin and brand, so fair and necessary attribute information that is the prerequisite for information transactions This is because the transmission can be easily realized.

However, in general, most of the fresh products are "low standard products" having low quality reproducibility. In order to correctly determine the value of low standardized products, it is necessary to make a judgment based on a large amount of attribute information and analysis know-how in accordance with expert's evaluation viewpoint for each product. Moreover, since the transaction is a kind of competition among participants who seeks to obtain better products at lower prices, participants are asked to "what attribute information should be analyzed and how". Tend to obey. Under such circumstances, it is not realistic to unilaterally transmit the attribute information from the exchange so that all the trading participants can be satisfied.

The object of the present invention is to efficiently obtain and use the information necessary for the value evaluation of a product, based on a unique viewpoint, by all trading participants in the information trading of low standardized products (processing). / Analysis). Other objects of the present invention can be easily inferred by those skilled in the art from the present specification and the accompanying drawings.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide an information trading system in which at least one exchange system and a plurality of buyer side systems are connected by a communication network, and the buyer side system is for evaluating the value of a product in advance. The information identifier and the information processing or analysis method are registered in the storage device, the product identifier is input from the input device, the product value evaluation information identifier is retrieved from the storage device, and the information transmission request is communicated. The information is transmitted to the exchange system via the network, the information is received from the exchange system via the communication network, and the received information is processed or analyzed based on the processing or analysis method registered in the storage device. By outputting the analysis result from the output device,
Achieved.

[0009]

According to the present invention, the buyer side system is based on the user's own viewpoint registered in advance in the storage device when the system user (trade qualified person) is willing to participate in the transaction. And send the information necessary for product value evaluation,
Automatically request the exchange system. In addition, the information received upon request is automatically processed or analyzed based on the user's unique viewpoint. As a result, even in information transactions targeting low standard products, all trading participants
Since the product value can be quickly evaluated based on each unique information, a series of transaction decision making can be made efficient.

Is input from the input device 2032. The planned transaction information includes basic information such as product type, production area, producer, shipper, transaction unit, and transaction quantity, as well as information useful for value evaluation of the product (value evaluation information). . The value of fresh produce is comprehensively evaluated in terms of size and quality.
For high standard products, equal class (grade and class) codes have sufficient reliability and are often used.

On the other hand, in the case of low standard products, since each trading participant has his or her own perspective, it is only necessary to use a uniform and intensive information expression by producers / shippers such as equal rank codes. Often insufficient. Therefore, T
It is necessary to express and provide the attribute information of a product as objectively and quantitatively as possible by using a V camera or a quality inspection device.

<Seller System: Step 3302>
Registration of planned transaction product information The planned transaction product information input in step 3301 is registered in the planned transaction product local DB 601 on the storage device 2034. FIG. 6 shows the logical structure of the planned transaction local DB 601 using the muskmelon as an example. Basic information 602 described above
In addition to (type 6021, place of origin 6022, producer 6023, shipper 6024, transaction unit 6025, transaction quantity 6026), class code 6031 and grade code 6034 are provided as value evaluation information 603 composed of size 6030 and quality 60301.

By inputting with the mouse 2012, the presence or absence of the intention to participate in the transaction is input.

<Buyer System: Step 4104>
Conditional branching by transaction participation intention If the system user has no transaction participation intention, all processing is terminated. On the other hand, if there is an intention to participate in the transaction, step 4105 is executed.

<Buyer system: Step 4105>
Retrieval of identifier of value evaluation information of transaction product The system user has registered his or her product-specific value evaluation viewpoint in the storage device 2014 in advance. FIG. 9 is a logical structure of a product-specific value evaluation viewpoint file 901 of a certain system user (probably Mr. X). In the product-based value evaluation viewpoint file 901, the value evaluation information name 902, the information processing method 903, and the analysis method 904 are classified by product type 910.
(Evaluation specific gravity 9041, evaluation point calculation formula 9042) are registered. In this file 901, Mr. X is the diameter of the fruit,
It shows that the weight, the front image of the appearance, the sugar content, and the acidity are considered to be useful information for the value evaluation of muskmelon. In this embodiment, the above information name is searched as an identifier of the value evaluation information of muskmelon.

<Buyer System: Step 4106>
Transmission request for transmission of information corresponding to the identifier The transmission request for the above information (information name and transmission destination) is transmitted to the exchange system 202 via the communication network 204.

<Exchange system: Step 4202> Reception of information transmission request From buyer side system 201 to communication network 204
A request for transmission of information is received via.

<Exchange System: Step 4203> Retrieval of Information Requested for Transmission Using the information name included in the received transmission request as a key, the corresponding information is retrieved from the planned transaction item common DB 701 of the storage device 2022. For example, the front image 60351 exists in the planned transaction item common DB 701, and is taken out.

<Exchange System: Step 4204> Conditional Branching Based on Search Results Among the information requested to be transmitted, the planned transaction item common DB 701
For those existing inside, the following step 4205 is executed. For example, as for the sugar content information 60361, for those that do not exist in the planned transaction item common DB 701,
Step 4206 is executed.

<Exchange system: Step 4205> Transmission of retrieved information The information retrieved from the planned transaction item common DB 701 is transmitted to the buyer side system 201 via the communication network 204.

<Exchange System: Step 4206> Transfer of Request to Send Information Among the information requested to be sent from the buyer side system 201, if it does not exist in the planned transaction item common DB 701, the seller via the communication network 204. The transmission request is transferred (transmitted) to the side system 203.

<Seller System: Step 4301>

For those existing in 01, execute step 4306. On the other hand, local D
If there is no B601, step 4304
To execute.

<Seller System: Step 4304>
New input of information Information (here, acidity information) that does not exist in the planned transaction item common DB of the exchange system 202 or the scheduled transaction item local DB of the seller system 203 is input device 2032.
Newly input from (specifically, acidity sensor).

<Seller System: Step 4305>
Additional registration of newly input information The newly input acidity information is additionally registered in the scheduled transaction local DB 601 on the storage device 2034.

<Seller System: Step 4306>
Transmission of information Value evaluation information retrieved from the planned transaction local DB 601 or newly input from the input device 2032 is transmitted via the communication network 204 to the buyer side system 20.
Send directly to 1.

<Buyer system: Step 4107>
Reception of Information Corresponding to Transmission Request The value evaluation information is received from the exchange system 202 or the seller system 203 via the communication network 204.

<Buyer system: Step 4108>
Processing / analysis of received information Product value evaluation viewpoint file 901 in storage device 2014
The received value evaluation information is processed / analyzed according to the processing method 903 or the analysis method 904 registered in. For example, in the case of muskmelon, appearance is an important determinant of quality, and it is possible to create a magnified image of the central part from the front image, or use well-known image processing techniques to improve the complexity and shape of the pattern ( Measure the sphericity). Further, for each information item, the evaluation score is calculated according to the evaluation score calculation formula 9042, and the evaluation specific gravity 9041 is multiplied and added to obtain the total evaluation score. For example, as the evaluation point of the fruit diameter, a numerical value expressing the ratio with the maximum expected diameter in percentage is used (maximum 100 points).

By the way, the above-mentioned comprehensive evaluation is merely an evaluation at the time of transaction, and the evaluation should change at the time of actually acquiring the actual transaction or at the time of selling to the consumer. Therefore, it is possible to identify a more appropriate product by predicting the evaluation at the time of actually acquiring the traded product or at the time of selling to the consumer. This prediction can be easily obtained by simulation from already-obtained quality information (sugar content, acidity, rate of change with time, etc.), assuming average distribution conditions.

<Buyer system: Step 4109>
Output of processing / analysis result The result of processing / analysis of information is output to the output device 2013. FIG. 10 shows an example of the output screen 1001. Here, in addition to the appearance image 1005, the measured value of each information item is 10
02, an evaluation score 1003, and a comprehensive evaluation (evaluation score at the time of transaction and at the time when three days have passed) 1004 are included.

(3) Transaction Execution Phase In the transaction execution phase shown in FIG. 5, the buyer side system 2
01 issues a buy order to the exchange system 202 based on the value evaluation of the trade target product obtained in the transaction review phase. On the other hand, the exchange system 202 collects buy orders from a plurality of buyer side systems 201 and executes a trade process,
Finally, "to whom""howmuch""how many (here 1
Decide whether to sell.

<Buyer system: Step 5101>
Input of Buy Order The price of muskmelon to be purchased is input as a buy order from the input device (mouse) 2012. FIG.
An example of a buy order input screen 1101 is shown in FIG. In the present embodiment, it is assumed that transactions are carried out by the auction method. The auction is a method of gradually increasing the price from a certain opening price, and the trading participant who placed the latest order becomes the contractor. The order is entered by picking the order button 1103 with the mouse 2012 when the indicator 1102 indicates the price below the desired upper limit price.

<Buyer system: Step 5102>
Sending Buy Order The buy order is sent to the exchange system 202 via the communication network 204.

Reception of Temporary Transaction Processing Result The temporary transaction processing result is received from the exchange system 202 via the communication network 204.

<Buyer system: Step 5104>
Output of temporary transaction processing result The received temporary transaction processing result is output from the output device 2013. Specifically, the temporary transaction price and the temporary contractor at that time are displayed in the order price display area 1104 and the orderer number display area 1105, respectively.

<Buyer system: Step 5105>
Input of evaluation for temporary transaction processing result Evaluation for received temporary transaction processing result (satisfaction / dissatisfaction)
Is input from the input device 2012. Here, it is assumed that the dissatisfaction will be input as the re-input of the order (see step 5106).

<Buyer system: step 5106>
Conditional branching based on evaluation result If there is dissatisfaction with the temporary transaction processing result, the process returns to step 5101 and the buy order is input again. If it is satisfied, step 5107 is executed.

<Exchange System: Step 5204> Judgment of End of Transaction If the next buy order does not arrive even after a predetermined time has elapsed from the reception of the buy order in step 5201, it is judged that the transaction has ended.

<Exchange System: Step 5205> Conditional Branching Based on Judgment Result If it can be considered that the transaction is completed, step 5206 is executed. Otherwise, return to step 5201.

Output of Final Result The completion of the transaction is indicated by changing the display mode (color or brightness) of the closed display area 1106 of the output device 2013. At that time, what is displayed in the order price display area 1104 and the orderer number display area 1105 is the final transaction processing result.

<Seller System: Step 5301>
Reception of Final Result The final result of the transaction processing is received from the exchange system 202 via the communication network 204.

In the above description, the information exchange of muskmelon was described as an example, but the present invention is not limited to this. INDUSTRIAL APPLICABILITY The present invention is effective for information trading of products such as carcass of bluefin tuna and beef whose unit price is high and the superiority or inferiority of the value evaluation viewpoints of trading participants is particularly important. Further, in this case, the internal structure of the product (such as the degree of frost) is also one of the decisive factors in the value evaluation, so that the 3D CT and MRI often used in the medical field are used.
The technique of "visualization of internal structure" as described above may be used for inputting the value evaluation information.

As described above, according to the second embodiment, in the information trading of perishable goods of low standard, all the trading participants can efficiently obtain the information necessary for the value evaluation of the goods based on their own viewpoints. It can be obtained and used (processed / analyzed) well to support accurate decision-making on transactions.

As a third embodiment, in the transaction examination phase and the transaction execution phase of the second embodiment, the buyer side system 201 is turned on so that the examination and execution of the transaction do not require manual intervention each time. A case where the output process is changed will be described. 12 and 13 are process flow diagrams of the transaction review phase and the transaction execution phase, respectively. 12 differs from FIG. 4 in that step 4102, step 4103, and step 4109 are deleted and step 12103 is added. Further, FIG. 13 is different from FIG. 5 in that step 5101, step 5104, step 5105, and step 5108 are deleted and step 13101 and step 13105 are added.
The newly added processing steps will be briefly described below.

<Buyer System: Step 1210
3) Creation of Transaction Participation Intention In advance, in storage device 2014, the types of products that are desired to participate in the transaction are registered in a table format, and when the transaction start notification of the corresponding type is received, the information indicating the intent to participate in the transaction is internally stored. create.

<Buyer System: Step 1310
1> Creation of Buy Order A knowledge base of order know-how is registered in the storage device 2014 in advance. Specifically, the relationship between the overall evaluation of the product and the purchase price is registered. That is, it is possible to determine "how much price should be purchased (upper limit price)" based on the evaluation value of the trading object obtained in the transaction examination phase.
Here, a buy order is created at an arbitrary price that does not exceed the upper limit price.

<Buyer System: Step 1310
5> Evaluation of temporary transaction processing result If another transaction participant is a temporary contractor within the range where the temporary transaction price does not exceed the upper limit price, the result is dissatisfied.

As described above, according to the third embodiment, in the information transaction of the low standardized perishable goods, the buyer side system automatically considers and executes the transaction in a form reflecting the intention of the transaction participant. can do.

Next, an embodiment of the apparatus configuration of the buyer side system 201 and the exchange system 202 which constitute the information transaction system of the present invention shown in FIG. 2 will be described with reference to FIGS. 14 and 15. The outline of the device configuration of each of the systems 201 and 202 is similar to that of FIG. The present embodiment will be described in correspondence with the functions described with reference to FIG.

As shown in FIG. 14, the buyer side system 2
01 includes an input device 2012, an output device 2013, a storage device 2014, and a computer 2011.
