TECHNICAL FIELD OF THE INVENTION
The present invention relates to a perishables electronic transaction apparatus for electronically trading perishables on a computer network, a control method thereof, a computer program, and a storage medium.
[0002]
[Prior art]
Perishable foods (fisheries, fruits and vegetables, meat, etc.) are special products in a sense because they depend on the season and region, unlike industrial products.
[0003]
For example, focusing on fresh food transactions, the wholesale market is still intervening, and it has a double triple structure that follows complicated distribution channels, conventional business practices and vested rights. Such an outdated market trading structure has caused its precision fatigue.
[0004]
Also, as a method of buying and selling fresh food, there is a method in which consumers and producers use the Internet network and conduct direct transactions, thereby realizing distribution of goods at clear goods and prices with minimal distribution channels. It has been proposed (for example, see Patent Document 1).

[0006]
[Problems to be solved by the invention]
However, in the method described in Patent Document 1, the problem of freshness, which is a characteristic of perishable foods, is not taken into account so much. In a case where a transaction is actually made, for example, it takes 24 hours to transport goods. However, there is a case where the freshness is impaired when it reaches the consumer.
[0007]
The present invention develops a virtual market on a computer network, enables both sellers and buyers to easily trade fresh food products, and trades fresh food products with impaired freshness. It is an object of the present invention to provide a fresh food electronic transaction device, a control method thereof, a computer program, and a storage medium which are not to be used.
[0008]

In order to solve this problem, for example, a perishables electronic transaction device of the present invention has the following configuration. That is,
A perishables electronic transaction device provided on a computer network for mediating electronic transactions of perishables,
A first method for receiving and storing provided product information from a fresh food selling terminal via the computer network, and providing the stored provided product information in response to a request from the fresh food purchasing terminal. Information provision means;
The purchase request information from the purchase side terminal is received and stored via a computer network, and, in response to a request from the sales side terminal of the corresponding fresh food, with respect to the purchase request information from each purchase side terminal, Second information providing means for providing at least information for displaying a list of orders and non-orders in a selectable manner;
After the display information is provided by the second information providing means, the order receiving / non-ordering information from the selling terminal is received and stored, and the selected content is provided to each purchasing terminal that has requested the purchase request information. And third information providing means.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0010]
<First embodiment>
FIG. 1 is a conceptual diagram of a system according to the embodiment. In the figure, reference numeral 1 denotes a server which forms a virtual fresh food market which is the core of the embodiment, and is connected to the Internet. Reference numeral 2 denotes a terminal installed on the seller side for fresh food, and reference numeral 3 denotes a terminal on the buyer side. The server 1, the terminals 2, 3 are each configured by a general-purpose information processing device such as a personal computer. The connection form of each device to the Internet does not matter. The terminals 2 and 3 need only operate at least a Web browser program (for example, a browser provided by Microsoft Corporation or Netscape Corporation in the United States), and the type of device is not limited.
[0011]
The server 1 includes a master database (DB) for registering and storing and managing sellers and buyers, transaction contents and a transaction DB for managing the same, and a fresh food DB for managing fresh food, which are members participating in the transaction of fresh food. (Mainly the name of the product to be bought and sold).
[0012]
The master DB includes, for example, as shown in FIG. 3, a member ID, a name, a representative, a type, a password, an address, a telephone number, transaction financial information (including an account number), and the like. Here, the "type" identifies whether the member is a seller (wholesale side) or a buyer side. In the case of "1", the member is the seller side (wholesale side). “3” on the buyer side indicates that it is a system administrator. The perishable food DB has only a name, and a description thereof will be omitted. The details of the transaction DB will be described later.
[0013]
The server 1 also includes an electronic trading board (program) that generates a file (to be transferred to the terminal) for setting a display screen related to a food transaction and that performs processing based on an input result from the terminal. Have.
[0014]
FIG. 2 shows an operation processing procedure (a program of the server 1) in the server 1. Hereinafter, the operation processing procedure in the server 1 will be described with reference to the same figure, but "... Screen display" is used for simplicity, and actually, a file is transmitted to the connected user terminal by the http protocol. This is the process of transferring. Each terminal uses a browser for display. That is, it is added that the displayed location is the display screen of the terminal on the user side.
[0015]
Each user operates his / her own terminal and connects to the server 1 via the Internet using a browser. At the time of connection, a login screen (not shown) is displayed in step S1, and a user ID and a password are input on the screen. Therefore, the server 1 refers to the master DB based on the ID at this time, and determines whether the login user is a seller, a buyer, or an administrator, as well as whether or not the user is an authorized member. You can do it.
[0016]
First, when the system administrator connects, a screen shown in FIG. 4 is displayed (step S2), and a desired item is clicked with a pointing device such as a mouse (hereinafter simply referred to as designation or selection). By using expressions, screens for various processes are displayed in accordance with the selected contents (step S3). Registration and deletion of users (members) (registration in the master DB), registration and deletion of products (registration of perishables DB), and deletion of data in various DBs are performed, while sellers (wholesale) If the user connects, a selection screen (not shown) on the seller side is displayed (step S4). There are basically two items to select here. One is a task of registering (exhibiting) a product on the net, and a task of performing order inquiry and order processing for the registered product.
[0017]
When the registration process is selected, a perishable food input (registration) screen as shown in FIG. 5 is displayed (in the illustrated case, the user name is "ABC fisheries"). The items to be entered here are the type (name) of the food item, the number of items in stock, the desired selling price per set, and the quality assurance period.
[0018]
In FIG. 5, a maximum of five items can be registered at a time using three units of a combo box for designating a product name, a quantity, and a desired wholesale price. However, by displaying this screen several times, it is possible to register six or more products, and in some cases, it is possible to register more than five products by scrolling. In the case shown in the figure, a state in which registration work of two items is being performed is shown.
[0019]
In this way, when ending the registration work, the "input" button is designated. As a result, the product is registered in the transaction completion DB of the server 1.
[0020]
As will be described before and after, the transaction DB includes a seller-side transaction DB, a buyer-side transaction DB, and a transaction completion DB that stores data on which a transaction has been established. In the above description, when the seller registers the product, the product is registered in the seller-side transaction DB.
[0021]
FIG. 6 shows the structure of the seller-side transaction DB. Since the user displaying the screen of FIG. 5 is “ABC Fisheries” (the ID is “00123” from FIG. 3), the registered contents are stored as shown in FIG. The same applies when another seller user registers. In the drawing, the transaction ID is a code for simplifying management of the server 1, and a unique code is issued for each product. The meaning of the pointer will be described later.
[0022]
In addition, when the seller-side user wants to view the order status of the merchandise registered by himself, he selects a transaction inquiry on the screen (not shown) displayed in step S4. Then, the process proceeds to step S6, in which a list (name, stock, desired wholesale price) of each product registered by the user and the current order status of each product (total number of sets of attention desired by each seller user) are displayed. (Not shown). Here, when, for example, the displayed registered product “one set of Kawabuta (special grade)” is selected, a screen shown in FIG. 7 is displayed.
[0023]
In the case shown in the figure, it indicates that an order has been received from three parties (buyers) (the number of rows increases in accordance with the number of users who are ordering). The display order is set to the order of the desired purchase price. In addition, you may make it possible to switch also in order of a desired number of sets.
[0024]
Although details of the processing on the buyer side will be described later, basically, when the buyer-side user wants to purchase a certain product, for example, "Kabuta 1 set special grade", the user searches for the product and the result is displayed. Order processing is performed for a desired one of a plurality of (possibly one) registered products.
[0025]
For example, when there are orders from several buyers for the transaction code A00253 in FIG. 6, the server 1 newly creates order data for the transaction code. In order to clarify the location of the created order data, it is provided for storing the address in a pointer shown in the figure.
[0026]
Now, the seller-side user browses the screen shown in FIG. 7, and the user (in the illustrated case, the terminal user of “ABC Fisheries”) accepts each order (accepts an order) or rejects it. Alternatively, whether to suspend at the present time is determined by clicking one of the radio buttons displayed on the right hand side of the screen ("pending" in the initial state). This operation is step S7 in FIG.
[0027]
FIG. 7 shows an example in which orders are received for the first two items and the last one is put on hold. This is because there is a possibility that the suspension can be changed to an order later. If this state is acceptable, the order processing button is designated. This order status is reflected in the status of the transaction ID in FIG. Although details will be described later, at this time, an update process is also performed on the buyer-side transaction DB.
[0028]
The buyer should be able to grasp the seller's order status for the products he ordered (described later), and if the seller responds that the order will be received, formally perform the work to place the order , The sale will be established. In addition, in FIG. 6, when the seller ID00501 trades with respect to the transaction ID00253, the data of this one row moves to the trade completion DB (not shown) and is deleted from the data of FIG. In addition, a process of subtracting the number of completed trades “30” from the stock number “300” of the transaction ID00253 in FIG. 6 is also performed. At this time, the transaction amount and the brokerage commission are also deducted.
[0029]
Next, an operation process on the buyer side will be described. In FIG. 2, when the seller-side user logs in to the server 1, a seller-side selection screen (not shown) is displayed in step S8. On this screen, one of the commodity order registered on the net (server 1) and the transaction inquiry is selected.
[0030]
When the order of the product registered on the net is designated, the process proceeds to step S9, and the search screen of FIG.
[0031]
The items to be entered here are the designation of the wholesaler (seller), the selection of goods, and the desired purchase price range. The wholesaler and the product selection are selected in a combo box format referring to the master DB and the perishable goods DB. As the wholesaler, as shown in the figure, all wholesalers and regions (for example, prefectures, and more extensively Kanto etc.) are shown. ) Or can be specified by individual wholesalers.
[0032]
By the way, in the drawing, all wholesalers are designated, and a special name (3 kg) of one set of Kawabuta is designated as a product name, and a desired purchase price of 4000 yen or more and less than 6000 yen is designated. In this state, when the search button is specified, the server 1 searches the seller-side transaction DB for data that matches the specified conditions, sorts the results in ascending order of the desired purchase price, and displays the screen information thereof. Transfer to the buyer. FIG. 9 shows the screen (the buyer in the case shown is “Super Nagomi”).
[0033]
The buyer side looks at this screen, specifies the desired purchase price and quantity (as shown in the figure, a plurality can be specified until the desired purchase quantity is satisfied), and if it is determined that the contents are satisfactory, the order is placed. The processing button will be specified.
[0034]
In this way, as long as there is a required product, the above operation is performed. As a result, as described above, the link by the pointer in FIG. 6 is established in each seller-side transaction DB. Such information is also registered in the buyer-side transaction DB.
[0035]
The structure of the buyer-side transaction DB is as shown in FIG. 10A, and includes a member ID, a transaction ID, a situation (unprocessed in an initial state), a product name, an order quantity, and a desired purchase price.
[0036]
As described above, on the individual seller side (wholesale side), any one of order acceptance, rejection, and hold is set, and this is reflected in the status column of the buyer-side transaction DB. For example, when ABC Fisheries, a seller, receives an order from "Super Nagomi" on the screen of FIG. 7, the buyer-side transaction DB changes from the state of FIG. 10 (a) to the state of FIG. Changes to In addition, FIG. 10B shows a state in which the seller side has rejected and has not processed (the seller side has not yet performed the work of receiving an order) for the other two “kawa pig sets”. It also indicates that the remaining "Ayu" has been reserved. “One set of bonito” remaining “unprocessed (initial value)” indicates a state in which the seller has not performed order processing.
[0037]
Now, when a transaction inquiry is designated in a state where the seller side business selection screen is displayed (step S8 in FIG. 2), the process proceeds to step S10, and an inquiry screen is displayed. FIG. 11 is an example of this, and is a display example based on the seller-side transaction DB (FIG. 10B).
[0038]
As shown in the figure, the response result on the seller side for each order is reflected and displayed. As shown in the figure, "rejection" is displayed as "not reconciled", and "order received" is displayed as "completed", as character strings that are easy for the seller to understand. In particular, if the display form of each line (for example, the color of the character, the color of the word inside the frame, the thickness of the character) is changed for each situation, it is possible to further visually distinguish the line.
[0039]
Here, the meaning of "update" on the screen is provided in case the seller responds to data displayed as "unprocessed" during display. In other words, by specifying this "update" button, the latest data at that time is displayed. When the "order confirmation" button is designated, the transaction is concluded, and the corresponding data in the seller's transaction DB and the seller's transaction DB are deleted, and the data is transferred to the transaction confirmation DB.
[0040]
Note that, for products that have been “mismatched”, such as fresh food, the data is deleted, but the order may be taken again, for example. In some cases, the seller may be contacted again by changing the purchase price without being deleted.
[0041]
As described above, according to the present embodiment, unlike the physical wholesale market up to now, fresh food items that need to be bought and sold early can freely participate in buying and selling via a network (Internet). This allows fresh food to flow early, and also allows the seller and the seller to reflect their trading strategies.
[0042]
<Second embodiment>
Hereinafter, a second embodiment according to the present invention will be described.
[0043]
In the following description, the description of the same parts as those in the first embodiment will be omitted, and the description will focus on the characteristic parts of the present embodiment.
[0044]
Although the second embodiment is also a perishable food electronic transaction device similar to the first embodiment, in the first embodiment, the server 1 determines the designated condition according to the designated condition of the buyer user in FIG. Is searched from the seller's transaction DB and the result is transferred to the buyer's side. In the present embodiment, the data of the wholesale company obtained by searching from the seller's transaction DB and obtained is ) And the location (delivery destination) of the buyer's user from the master database in FIG. 2 and calculating the time required for transportation, as a result, the quality assurance period registered in the seller's transaction DB when the goods arrive at the buyer's side Is configured not to be transferred to the buyer side.
[0045]
FIG. 12 is a transport time DB in which the time required to transport the product is described.
In the figure, it means that it takes 24 hours to transport goods from, for example, Sapporo to Naha.
[0046]
Here, if the buyer's address is Sapporo City and the seller's address is Naha City, the quality assurance period registered in the seller's transaction DB was 15 hours even if the price matched the conditions. In such a case, the quality assurance period expires upon the arrival of the product, so the product is not transferred to the buyer.
[0047]
FIG. 13 is a flowchart from the time when the perishable food electronic transaction device receives the search condition from the buyer terminal to the time when the result is transmitted as screen information.
[0048]
Steps S101 to S102 show processing of the buyer terminal, and steps S201 to S208 show processing of the perishables electronic transaction device.
[0049]
First, in step S101, when the buyer transmits the commodity search condition, the perishables electronic transaction device receives the search condition in step S201, and searches the seller transaction DB in step S202. In step S203, it is determined whether or not there is an object. If there is no object, the search result is transmitted to the buyer terminal. Up to this point, it is the same as in the first embodiment.
[0050]
On the other hand, if the target product is found in step S203, the transport time DB is referred to for each found product in step S204. Next, in step S205, it is determined whether or not the quality assurance period has passed upon arrival. If it is determined that the time has passed, in step S206, the corresponding product is deleted from the search result obtained in step S202, and the process proceeds to step S207. move on. In step S207, it is determined whether or not the processing has been performed for all the corresponding products. If there are any remaining products, the process returns to step S204 and the same processing is repeated. On the other hand, if the processing has been completed for all the corresponding products, the process proceeds to step S208, where screen information displaying the search result is transmitted to the buyer's terminal, and the buyer's terminal receives and completes the processing in step S102.
[0051]
In the above embodiment, the description has been made mainly on fresh fish, but it is apparent that the present invention can be applied to other fresh food products such as agricultural products. However, in the case where fresh fish and agricultural products are used as a common DB, for example, when searching for data on fresh fish, the load on the server increases when agricultural products are mixed, so that a different transaction DB, fresh food DB It is desirable to provide.
[0052]
In addition, the seller side also provides the server 1 with an image of a fresh food item that can be provided (such as an image captured by a digital camera) and stores the image, and the buyer side views the image as necessary. It does not matter.
[0053]
Further, in the above embodiment, the seller-side user selects the order, rejects, or puts on hold based on the requirements (number and desired purchase price) of the seller who has placed the order, but continues to buy and sell. As you do so, you will need to focus on whether you are good or not. Therefore, the server 1 may be provided with a database for managing customers for each seller, where the database may be freely ranked and managed. In this case, an item for displaying the rank may be provided in FIG. 7, and the item may be displayed for each supplier.
[0054]
Although not described in detail, when a trade is made, the trade completion DB stores the seller side and the seller side, a product name, a quantity, a trade price, and the like. If a small number of transport vehicles are automatically arranged with reference to a separately provided product transport DB, transport costs can be minimized.
[0055]
Further, as is apparent from the above embodiment, the server 1 and the terminals 2 and 3 can be realized by a general-purpose information processing device such as a personal computer. In short, the terminals 2 and 3 only need to run a browser program, and the server 1 only needs to run a server program that implements the above processing.
[0056]
Therefore, the present invention uses a software program for realizing the functions of the above-described embodiments by using an information transmission means (a storage medium, a wired signal via a line or a network, or a wireless signal of light or radio waves) in a system or an apparatus. If the computer of the system or apparatus reads the program from the information transmission means and / or from the storage device once installed in the storage device such as a hard disk, the computer reads the program into the RAM. It is also applicable when executing.
[0057]
