When the buyer 3 performs an operation indicating confirmation of estimate request information on the specification confirmation screen of the requested product displayed subsequently on the input screen, for example, selecting an OK button or pressing a transmission button, each input data is determined. It is sent to the supporter system 20 via the web browser of the terminal 30 (step ST4).
[0041]
The supporter system 20 takes out the data necessary for calculating the estimate from the master 22b related to the cost information for the estimate registered in advance in the data storage unit 22 by using the transmitted information of the estimate request as a key. The cost and the estimate are calculated according to different calculation logic (step ST5).
[0042]
The generated estimation result for each vendor is registered in the master 22d holding the estimation history of the supporter system 20 (step ST6), and at the same time, the estimation result screen is generated by processing the estimation result into an appropriate display format. Information to be displayed is transmitted to the terminal 30 of the buyer who has made a request for quotation (step ST7). An example of the layout of the screen displayed on the Web browser of the terminal 30 at this time is shown in FIG.
[0043]
On the other hand, a notification that informs the vendor that an inquiry for an estimate item has come, for example, an email, is transmitted from the supporter system 10 to each vendor terminal 40 via a communication line (step ST8).
[0044]
(2) Processing related to bidding from vendors
Processing related to bidding from the vendor 4 will be described with reference to FIG. The vendor 4 who received the inquiry about the quotation item, for example, the e-mail, sends the URL of the supporter system 20 via the web browser of the vendor terminal 40 and then follows the screen for user authentication downloaded after the URL is sent. Information necessary for identifying the user such as an ID and a password is input and transmitted from the terminal 40 to the supporter system 20 via the communication line (step ST9).
[0045]
The supporter system 20 performs user authentication with reference to the master 22a holding member information (step ST10), and generates a screen for displaying a list of estimated cases when authenticated as a vendor registered as a member. The list information is transmitted to the terminal 40 (step ST11).
[0046]
Based on the list information received from the supporter system 20, the terminal 40 displays a list of the estimated cases. The vendor 4 selects a case for which an inquiry has been received from the list of estimated cases displayed on the screen, and transmits it to the supporter system 20 (step ST12). For the received case, the supporter system 20 searches for the case requested by the vendor 4 from the master 22d holding the estimate history in which the estimate result is registered for each case (step ST13). A screen in which the retrieved result is processed and generated into an appropriate display format is transmitted to the terminal 40 (step ST14). The above screen is a screen having a function of correcting the estimation result, and a screen having a function of making an answer. As described above, the information on the screen is transmitted to the terminal 40 from the supporter system 20 to the terminal 40 in step ST14. An example of such a screen is shown in FIG. This screen includes a field for inputting specifications, an estimate result, a price correction for the estimate result, a display area for accepting bid acceptance or decline, for example, a button for selecting accept or decline, A column for filling in the reason for declining a bid. In addition, a column for entering a comment including a message for the buyer is displayed. When the vendor 4 inputs necessary information in the input area of the screen and then presses the send button, each input data is confirmed and transmitted to the supporter system 20 via the web browser of the vendor terminal 40 (step ST15). ).
[0047]
The supporter system 20 registers the information representing the transmitted bidding result in the master 22d that holds the history of quotation (step ST16). Further, a notification is sent to the buyer 3 who requested the quotation that the bid has been received, for example, by e-mail to the terminal 30 of the buyer who requested the quotation (step ST17).
[0048]
Note that the supporter system 20 has a function of not accepting a bid response including a correction of the quotation from each vendor after the estimated correction deadline has passed, that is, performs a process. In this case, the result calculated by the supporter system 20 may be registered as the final result.
[0049]
In addition, for example, among the estimation results of each vendor calculated by the supporter system, a process is performed to give the right to enable a reply to a bid to a predetermined number of companies, for example, 5 companies in order from the lowest price, You may make it memorize. In this way, it is possible to limit the bidding response right from each vendor. As a result, it is possible to suppress the processing of frequent special price estimates by the vendor terminal 40, and it is possible to prevent the calculation result calculated by the supporter system from becoming obscured.
[0050]
In addition, when granting the right to bid response, a different limitation condition is set for each of price priority, delivery date priority and reliability priority, and this condition is held in the storage device, and the supporter system in light of the held conditions Selects a predetermined number of vendors, registers them in the storage means, and transmits the result of the estimation to the terminal 40 of the registered vendor. In this way, it is possible to give diversity to the right granting of secondary answers.
[0051]
(3) Processing related to successful bids from buyers
Processing related to a successful bid from the buyer 3 will be described with reference to FIG. The buyer 3 who has received a bid notification from the supporter system 20, for example, an e-mail, sends the URL of the supporter system 20 via the web browser of the buyer terminal 30, and then follows the screen for authenticating the user to be downloaded Information necessary for identifying the user such as an ID and a password is input and transmitted to the supporter system 20 (step ST18).
[0052]
The supporter system 20 performs user authentication with reference to the member master 22a (step ST19), and generates a bidding item list screen and transmits it to the buyer terminal 30 only when the buyer is authenticated as a member (step ST19). Step ST20).
[0053]
The buyer 3 selects a case that has received the bidding notification mail from the bidding case list screen, and transmits it to the supporter system 20 (step ST21). The supporter system 20 retrieves a case requested by the buyer 3 from the quotation history master 22d in which the estimation result is registered for each case (step ST22), and processes and generates the extracted result in an appropriate display format. A successful bid selection screen is transmitted to the buyer terminal 30 (step ST23). This bidding result / successful bid selection screen displays a bidding acceptance result, an estimate correction result, etc., and a successful bidder selection item for selecting a successful bid vendor for the item requested by the buyer 3. When the buyer selects a successful bidder and then presses the send button, each input data is confirmed and sent to the supporter system 20 via the Web browser of the buyer terminal 30 (step ST24).
[0054]
The supporter system 20 registers the transmitted successful bid result information in the estimation history master 22d (step ST25). In addition, although the said estimation method was demonstrated along the series of flows of a request for quotation, a bid, and a successful bid, it is not limited to the said flow, The buyer 3 and the vendor 4 access the supporter system 20, and are the past.
