Description

The present invention relates to a computer, a control method, and a program.

When procuring steel frames for use in construction, construction companies such as general contractors request fabricators to manufacture the steel frames. Requests for the manufacture of steel frames are usually made before official drawings are prepared for estimates, so fabricators secure future manufacturing schedules in advance based on the details of the request.

Japanese Patent Application Publication No. 2005-174064

However, because manufacturing schedules frequently change due to delays in construction projects, fabricators are likely to have busy and off-season periods. Furthermore, if a fabricator in the local community cannot secure a manufacturing schedule, it is difficult for a construction company to find a fabricator to request.
An object of the present invention is to provide a computer, a control method, and a program that can mediate between a steel frame orderer and a fabricator.

According to one aspect of the present invention, the server is a server that communicates via a network with an orderer who orders a steel frame and a plurality of fabricators who manufacture the steel frame, and the server communicates with an orderer who orders a steel frame and a plurality of fabricators who manufacture the steel frame, and includes order information indicating an order for the steel frame from the orderer. an order information receiving unit that receives the order information, an order information transmitting unit that sends the order information to the plurality of fabricators, and an order information transmission unit that sends the order information indicating that the order indicated by the order information is received to one of the plurality of fabricators. an order information receiving section that receives order information from a plurality of candidate fabricators, which is a section; and a candidate presenting section that presents at least a part of the plurality of candidate fabricator information indicating each of the plurality of candidate fabricators to the orderer. .

According to the above aspect, it is possible to mediate between a steel frame orderer and a fabricator.

<First embodiment>
《Structure of steel ordering system 1》
Hereinafter, embodiments will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram showing a steel frame ordering system 1 according to the first embodiment.
The steel frame ordering system 1 mediates transactions of small lots of steel frames between steel frame orderers such as construction companies and trading companies and fabricators that manufacture steel frames. Small-lot steel frames refer to steel frames weighing less than 300 tons. The steel frame ordering system 1 includes a server 100, a plurality of orderer terminals 200A, and a plurality of fabricator terminals 200B. Server 100 is operated by a platformer. The orderer terminal 200A is a terminal device 200 owned and operated by the orderer. The fabricator terminal 200B is a terminal device 200 owned by the fabricator and operated by the fabricator. The server 100 communicates with the orderer terminal 200A and the fabricator terminal 200B via the network. The steel frame ordering system 1 accepts registration of orderers and fabricators regardless of location. In other words, the steel frame ordering system 1 acts as an intermediary for fabricators nationwide and orderers nationwide.

《Outline of mediation procedure》
FIG. 2 is a schematic sequence diagram showing the flow of mediation by the steel ordering system 1 according to the first embodiment.
The orderer operates the orderer terminal 200A and transmits steel frame order information to the server 100 (step S1). The order information includes at least drawings used for calculating the quantity of steel frames and quotation conditions. Initial transmission of order information is usually performed before receiving a building request in order to create an estimate used for price negotiations with the building client. Therefore, the drawings included in the initial order information are usually approximate drawings.

Upon receiving the order information, the server 100 calculates the quantity and unit price of the steel frame based on the drawings and quotation conditions included in the order information, and generates quotation information indicating the price of the steel frame related to the order information (step S2). . The server 100 transmits the generated estimate information to the orderer terminal 200A (step S3). That is, since the server 100 creates the estimate information based on the rough drawings, the fabricator does not need to create the estimate information based on the rough drawings. Since the orderer can obtain estimate information without having to decide on a fabricator to contract with, the orderer can secure freedom in selecting a fabricator. Further, if the drawing included in the order information is a rough drawing, the server 100 does not present the order information to the fabricator. This eliminates the need for the fabricator to secure an uncertain schedule in advance.

Every time the orderer updates the drawing, the orderer operates the orderer terminal 200A to update the order information and sends it to the server 100 (step S4). The server 100 generates estimate information based on the received order information (step S5), and transmits it to the orderer terminal 200A (step S6). Note that the server 100 charges the orderer a fee for generating the estimate information each time it transmits the estimate information to the orderer terminal 200A. Thereafter, when the orderer accepts a building request from the client and the formal drawings are completed, the orderer operates the orderer terminal 200A and transmits the order information including the formal drawings to the server 100 (step S7). .

Upon receiving the order information, the server 100 calculates the quantity and unit price of the steel frame based on the drawings and quotation conditions included in the order information, and generates quotation information indicating the price of the steel frame related to the order information (step S8). . Next, the server 100 presents the received order information and the generated estimate information to the fabricator registered in advance (step S9). Fabricators are required to pay an annual membership fee to register with the steel ordering system 1. The fabricator can view order information and estimate information by operating the fabricator terminal 200B and accessing the server 100.

The fabricator decides whether or not to accept the order based on the presented order information and estimate information. If the fabricator does not receive an order, it does not take any action on the estimate information and leaves it as is. On the other hand, if the fabricator wishes to receive an order, the fabricator operates the fabricator terminal 200B, corrects the unit price included in the presented estimate information to the unit price desired by the fabricator (step S10), and transmits the revised estimate information. The order information including the order information is transmitted to the server 100 (step S11). In other words, the fabricator does not need to calculate the quantity of steel frames from the drawings, and can generate estimate information simply by modifying the unit price of the steel frames. Therefore, even if the fabricator loses an order based on the order information, there is less work to be done, so there are fewer disadvantages to using the steel frame ordering system 1. In addition, in transactions of small lots of steel frames, the ratio of labor costs to material costs increases, so the unit price of steel frames tends to vary depending on the fabricator.

When the server 100 receives order information from a plurality of fabricators (candidate fabricators), the server 100 selects a fabricator with a good evaluation, a fabricator located near the construction site, and a fabricator with a low estimate from among the fabricators that received the order information. The fabricator is extracted as a fabricator recommended to the orderer (step S12). The server 100 presents the extracted order information of the fabricator along with the evaluation of the fabricator to the orderer terminal 200A (step S13).

The orderer decides which fabricator (contract fabricator) to order the steel frame from based on the presented information. The orderer operates the orderer terminal 200A to notify the server 100 of the fabricator determined as the order destination (step S14). The server 100 notifies the fabricator terminal 200B of the fabricator determined as the order destination of the confirmation of the order (step S15). At this time, the server 100 presents the guarantee contract provided by the platform to the orderer and the fabricator, and receives an input as to whether or not to conclude the guarantee contract. Upon determining the order destination, the server 100 charges the orderer a brokerage fee.

Fabricators can receive orders after the formal drawings are completed, so the period from receiving the order to starting steel frame production can be shortened, compared to the case where orders are received at the time of rough drawings. Therefore, the fabricator can suppress schedule fluctuations. Fabricators can also accept ready-to-start steel manufacturing orders during off-season periods.
Thereafter, when the delivery of the steel frame by the fabricator is completed, the server 100 receives fee settlement information from the fabricator terminal 200B as necessary (step S16), and transmits the settlement information to the orderer terminal 200A (step S17). . As a result, a steel frame commercial transaction is established between the orderer and the fabricator. Note that the ownership of the steel frame is directly transferred between the fabricator and the orderer, and the platform company that operates the server 100 does not receive ownership of the steel frame from the fabricator. After the transaction is completed, the server 100 receives individual evaluation information indicating the fabricator's evaluation from the orderer terminal 200A, and also receives individual evaluation information indicating the orderer's evaluation from the fabricator terminal 200B (step S18). Thereby, the server 100 updates the evaluation information of the orderer and the fabricator.

In this way, according to the steel frame ordering system 1 according to the first embodiment, since the period from receiving an order to starting production is short, the fabricator can suppress the occurrence of slow periods. Further, according to the steel frame ordering system 1, an orderer can easily select a fabricator to order from among fabricators nationwide.

<<Configuration of server 100>>
The detailed configuration of the steel frame ordering system 1 will be described below.
FIG. 3 is a block diagram showing the configuration of the server 100 according to the first embodiment. The server 100 includes a registration reception section 101, a user database 102, a payment confirmation section 103, a setting section 104, a billing section 105, an order information reception section 106, a calculation section 107, a rough estimate transmission section 108, an order information transmission section 109, and order information. It includes a receiving section 110, a candidate presenting section 111, a candidate selecting section 112, a contract presenting section 113, a notification section 114, a payment processing section 115, and an evaluation receiving section 116.

The registration reception unit 101 receives registration for use of the steel frame ordering system 1 from the orderer terminal 200A and the fabricator terminal 200B. For example, the registration reception unit 101 receives input of usage registration information including a corporate name, location, name of person in charge, classification of orderer or fabricator, account information, email address, and password. The registration reception unit 101 records the input usage registration information in the user database 102. The account information may indicate an account with a credit card, bank, payment service, or the like. Note that the registration reception unit 101 causes the usage rules of the steel frame ordering system 1 to be displayed on the usage registration information input screen or the like. Usage rules include, for example, steel frame settlement rules and problem-solving rules. Rules for steel frame settlement include, for example, accepting settlement when the error between the estimated steel quantity and actual quantity exceeds a predetermined value, and not accepting settlement when the error does not exceed a predetermined value.

The user database 102 stores usage registration information, the registration status of the user related to the usage registration information, evaluation information, and payment status in association with each other. The registration status takes either unregistered or registered. For example, the platform operator that operates the server 100 investigates the user when the user is registered, evaluates the user, and records evaluation information indicating the evaluation result in the user database 102. The evaluation information may be represented by, for example, a numerical value indicating a five-level evaluation. Furthermore, the evaluation information may include a character string that describes the characteristics of the user. The deposit status indicates whether or not the annual membership fee has been deposited by the user. Note that the orderer is registered by being confirmed by the platform after entering the usage registration information. On the other hand, a fabricator becomes registered after inputting usage registration information, confirmation by the platform, and payment of an annual membership fee. Since the orderer does not pay the annual membership fee, the payment status for the orderer may be NULL.

The billing unit 105 bills the user of the steel frame ordering system 1 for usage fees.
Specifically, the billing unit 105 bills the fabricator whose usage registration information is registered in the user database 102 for an annual membership fee. Furthermore, when the rough estimate transmitting section 108 transmits rough estimate information to the orderer, the billing section 105 charges the orderer a fee for preparing the rough estimate. Furthermore, when the orderer decides on a fabricator from which to order steel frames, the billing unit 105 charges the orderer an introduction fee. Further, the billing unit 105 bills the user for a guarantee fee when the user concludes the guarantee contract presented by the contract presenting unit 113.
The billing unit 105 generates billing information based on account information recorded in the user database 102, for example, and executes billing processing.

The payment confirmation unit 103 determines whether the annual membership fee has been paid by the fabricator. That is, the payment confirmation unit 103 determines whether or not there is a deposit from the account indicated by the account information indicated by the usage registration information. The payment confirmation unit 103 updates the deposit status stored in the user database 102 based on the deposit determination result. The payment confirmation unit 103 rewrites the registration status of the user database 102 to unregistered if the annual membership fee has not been paid by the fabricator.

The setting unit 104 causes the orderer terminal 200A to display an input screen for steel frame order information in response to the access from the orderer terminal 200A. FIG. 4 is a diagram showing an example of an order information input screen according to the first embodiment. On the input screen, input is required to enter the project name, location of the construction site, construction period, construction start date, order conditions, quotation conditions, drawings, and the classification of whether the drawings are rough drawings or official drawings. Contains forms. The estimation conditions include, for example, drawing conditions, material conditions, processing conditions, rust prevention conditions, evaluation management conditions, on-site handling conditions, document conditions, and the like. Examples of the drawing conditions include whether or not it is necessary to create a work drawing, whether or not it is necessary to create a combination drawing, and whether or not it is necessary to create a temporary drawing. Examples of material conditions include the type of steel frame members, the necessity of material procurement, and the presence or absence of manufacturer specifications. Examples of processing conditions include the presence or absence of machining, the presence or absence of embedded hardware, and the presence or absence of bending. Examples of rust prevention conditions include the type of surface treatment, the presence or absence of undercoating, and the presence or absence of special coating. Examples of evaluation management conditions include the necessity of various on-site inspections. Examples of on-site conditions include whether or not a match is required, whether or not a knife work is required, and whether or not a blacksmith work is required. Examples of document conditions include the necessity of various manuals, plans, and reports. The quotation conditions may be displayed in a selectable manner using, for example, a check box or a pull-down menu. The order acceptance conditions indicate the conditions of a fabricator that can receive an order for the production of steel frames. The order conditions represent, for example, the grade and evaluation of the fabricator. Further, the quotation conditions may be input using an interactive input system using a chatbot or the like.
The drawing may be a two-dimensional drawing represented by bitmap data or vector data, or a three-dimensional drawing represented by CAD (Computer Aided Design) data or BIM (Building Information Modeling) data. Good too.

The order information receiving unit 106 receives order information input by the orderer terminal 200A. Note that if the classification of rough drawings and official drawings included in the order information indicates that the drawings are official drawings, the order information receiving unit 106 treats the order as confirmed. In other words, the order information receiving unit 106 is an example of a confirmation unit that receives confirmation of order information from an orderer.

The calculation unit 107 calculates the quantity and unit price of each type of steel frame based on the drawings and estimation conditions included in the order information. For example, the calculation unit 107 calculates the quantity and unit price of each type of steel frame using the following procedure.
The calculation unit 107 estimates the detailed part from the drawing, and calculates the quantity of each type of steel frame based on the estimated detailed part. The calculation unit 107 calculates the quantity of each type of steel frame using a model that inputs, for example, the material conditions included in the drawing and estimate conditions and outputs the quantity of each type. The calculation unit 107 estimates the amount of welding of the steel frame based on the determined quantity of each type of steel frame. The calculation unit 107 estimates the degree of difficulty in machining the steel frame from the estimated welding amount, the weight of the steel frame per piece, and the machining conditions. The calculation unit 107 calculates the unit price for each type of steel frame based on the market price of the steel frame, the processing difficulty level, and the estimation conditions.
The rough estimate transmitting section 108 generates rough estimate information based on the quantity and unit price of each type of steel frame calculated by the calculating section 107, and transmits it to the orderer terminal 200A that transmitted the order information.

When the classification of the drawing included in the order information is a formal drawing, the order information transmitting unit 109 sends the order information and rough estimate information indicating the quantity and unit price of each type of steel frame calculated by the calculation unit 107 to the user. It is sent to the fabricator stored in the database 102. The rough estimate information is represented by, for example, CSV data. For example, the order information sending unit 109 may send an e-mail with order information attached to the fabricator's e-mail address, or send an e-mail containing a URL for accessing the order information viewing screen to the fabricator. You can also send it to the email address. Further, the order information transmitting unit 109 may transmit an order information viewing screen to the fabricator terminal 200B when the fabricator terminal 200B accesses the server 100.

The order information receiving unit 110 receives order information indicating a desire to receive a steel frame order indicated by the order information from the fabricator terminal 200B. The order information includes formal quotation information. The formal estimate information is data obtained by rewriting the unit price portion of the rough estimate information transmitted by the order information transmitting unit 109 by the fabricator. That is, the official estimate information is an example of unit price correction information for correcting the unit price calculated by the calculation unit 107. Further, the official estimate information is an example of order price information indicating the order price of the steel frame. Note that order information is not necessarily received from all fabricators. For example, a fabricator that cannot accept orders due to a busy season does not send order information. Hereinafter, the fabricator that sent the order information will also be referred to as a candidate fabricator.

When the number of order information received by the order information receiving section 110 reaches a certain number, or when a certain period of time has passed since the order information receiving section 110 received the order information, the candidate presenting section 111 displays a plurality of received order information and the user. Based on the information stored in the database 102, three recommended fabricators are extracted from the plurality of candidate fabricators. For example, the candidate presenting unit 111 extracts recommended fabricators using the following procedure.
The candidate presenting unit 111 converts each of the order price indicated by the formal estimate information included in the order information, the distance from the location of the fabricator to the construction site, and the evaluation of the fabricator into a score. The lower the order price, the higher the score, the shorter the distance from the location to the construction site, the higher the score, and the higher the fabricator's evaluation, the higher the score. The score may be determined, for example, by the standard deviation of the candidate fabricator as a population. The candidate presentation unit 111 selects the candidate fabricator with the highest order price score and the highest distance score among the candidate fabricators whose total score is equal to or higher than a predetermined threshold, or among the candidate fabricators whose scores are within a predetermined number of top candidates. The one with the highest evaluation score and the one with the highest evaluation score are each extracted as recommended fabricators.
In other words, the candidate presentation unit 111 selects candidate fabricator information related to a candidate fabricator whose location is closer to the construction site than other candidate fabricators, and whose order price is lower than other candidate fabricators, among a plurality of candidate fabricator information. Candidate fabricator information related to a candidate fabricator and candidate fabricator information related to a candidate fabricator with a higher evaluation than other candidate fabricators are extracted.

The candidate presentation unit 111 transmits to the orderer terminal 200A a competitive estimate screen that presents order information and evaluation information regarding the extracted recommended fabricators in a comparable manner. FIG. 5 is a diagram showing an example of a mutual estimate screen according to the first embodiment. As shown in FIG. 5, the locations, evaluations, and order prices of three recommended fabricators are displayed side by side on the competitive estimate screen. Regarding the order price, the unit prices and amounts presented by the three recommended fabricators are displayed side by side for each item.

The candidate selection unit 112 receives a selection of a contracted fabricator from which to order a steel frame from among the three recommended fabricators from the orderer terminal 200A. The orderer terminal 200A selects a contract fabricator by pressing the order button associated with the desired fabricator on the mutual estimate screen shown in FIG.

The notification unit 114 notifies each candidate fabricator of whether or not the order for the steel frame can be accepted. Specifically, when the candidate presenting unit 111 extracts three recommended fabricators, the notification unit 114 notifies the candidate fabricators that were not extracted that the order cannot be accepted. Further, when the candidate selection unit 112 receives the selection of a contracted fabricator, the notification unit 114 notifies the recommended fabricator that was not selected that the order cannot be accepted. Furthermore, when the candidate selection unit 112 receives the selection of a contracted fabricator, the notification unit 114 notifies the recommended fabricator that the order has been accepted.

The contract presentation unit 113 presents guarantee contract information regarding the order to the orderer and the contract fabricator when the contract fabricator is selected by the candidate selection unit 112. A guarantee contract is a contract concluded between a user who is an orderer or a contract fabricator and a platformer, and is a contract in which the platformer is obligated to pay when debts are not paid between the users. . The contract presentation unit 113 receives a request from the user as to whether or not to conclude a guarantee contract indicated by the compensation contract information presented.

The settlement processing unit 115 receives performance information indicating the actual quantity of manufactured steel frames from the fabricator terminal 200B. Settlement processing unit 115 receives input of settlement information indicating charges after settlement from fabricator terminal 200B when the error between the actual quantity indicated by the actual performance information and the quantity calculated by calculation unit 107 exceeds a predetermined value. On the other hand, the settlement processing unit 115 does not accept settlement information when the error between the actual quantity indicated by the actual performance information and the quantity calculated by the calculating unit 107 does not exceed a predetermined value.

The evaluation reception unit 116 receives input of individual evaluation information indicating the evaluation of the contracted fabricator from the orderer. The evaluation reception unit 116 also receives input of individual evaluation information indicating the orderer's evaluation from the contract fabricator. The individual evaluation information may be represented by, for example, a numerical value indicating a five-level evaluation. Furthermore, the evaluation information may include a character string that describes the characteristics of the user. The evaluation reception unit 116 updates the evaluation information stored in the user database 102 based on the received individual evaluation information. For example, the evaluation reception unit 116 updates the evaluation information by calculating the average value of the numerical values indicated by the individual evaluation information. For example, the evaluation reception unit 116 adds a character string included in the individual evaluation information to a character string related to the evaluation information.

<<Configuration of terminal device 200>>
FIG. 6 is a block diagram showing the configuration of the terminal device according to the first embodiment. The orderer terminal 200A and the fabricator terminal 200B are terminal devices 200 that communicate with the server 100. The terminal device 200 includes a receiving section 201, a display control section 202, an input section 203, and a transmitting section 204. The receiving unit 201 receives data from the server 100. The display control unit 202 causes the information received by the receiving unit 201 from the server 100 to be displayed on a display device such as an LCD panel or a touch panel. The input unit 203 receives input operations from a user via an input device such as a keyboard, mouse, or touch panel. The transmitting unit 204 transmits the data input to the input unit 203 to the server 100.

《Operation of steel ordering system 1》
FIG. 7 is a first flowchart showing the operation of the server 100 according to the first embodiment. FIG. 8 is a second flowchart showing the operation of the server 100 according to the first embodiment. When the orderer operates the orderer terminal 200A and accesses the server 100, the setting unit 104 generates input screen data for order information and transmits it to the orderer terminal 200A (step S101). When the receiving unit 201 of the orderer terminal 200A receives order information input screen data from the server 100, the display control unit 202 causes the display device to display an order information input screen as shown in FIG. The input unit 203 of the orderer terminal 200A receives input of order information from the orderer. When the estimate request button on the input screen is pressed by an orderer's operation, the transmitter 204 of the orderer's terminal 200A transmits order information to the server 100.

Upon receiving the order information (step S102), the order information receiving unit 106 of the server 100 determines whether the classification of whether the order information is a rough drawing or a formal drawing indicates that the drawing is a formal drawing. (Step S103).

If the classification indicates approximate drawings (step S103: NO), the calculation unit 107 calculates the quantity and unit price for each type of steel frame based on the drawings and quotation conditions included in the order information received in step S102 (step S104). The rough estimate transmitting unit 108 generates rough estimate information based on the quantity and unit price of each type of steel frame calculated in step S104 (step S105). The rough estimate transmitting unit 108 transmits the generated rough estimate information to the orderer terminal 200A (step S106). At this time, the billing unit 105 reads the orderer's account information from the user database 102, and performs billing processing for fees related to the generation of estimate information based on the account information (step S107).

When the receiving unit 201 of the orderer terminal 200A receives the rough estimate information from the server 100, the display control unit 202 displays the received rough estimate information on the display device. This allows the orderer to obtain a rough estimate for the steel frame without selecting a fabricator. Note that when the classification of the order information indicates a rough drawing, the server 100 does not present the order information to the fabricator terminal 200B.

On the other hand, if the classification of the order information indicates formal drawings (step S103: YES), the calculation unit 107 calculates the quantity and unit price for each type of steel frame based on the drawings and quotation conditions included in the order information received in step S102. is calculated (step S108). The order information transmitting unit 109 generates rough estimate information based on the quantity and unit price of each type of steel frame calculated in step S108 (step S109). The order information transmitting unit 109 transmits the generated rough estimate information, the order information received in step S102, and the orderer's evaluation information to the user database 102 when the registration status indicates registration and the order acceptance conditions included in the order information. The information is sent to a fabricator that satisfies the requirements (step S110). At this time, the order information transmitting unit 109 may further transmit a work drawing generated based on the official drawing to the fabricator together with the order information. For example, the server 100 accepts the upload of a work drawing created by a platformer, and sends the uploaded work drawing to a fabricator. This eliminates the need for fabricators to create work drawings for projects for which orders are not guaranteed.

When the receiving unit 201 of the fabricator terminal 200B receives the rough estimate information, order information, and evaluation information, the display control unit 202 displays the received rough estimate information, order information, and evaluation information on the display device. Based on the displayed information, the fabricator determines whether or not the fabricator wishes to accept the order for the steel frame indicated by the order information. When the fabricator desires to receive an order, the fabricator generates formal estimate information by modifying the unit price indicated by the rough estimate information. The transmitter 204 of the fabricator terminal 200B transmits order information including formal estimate information to the server 100.

When the server 100 transmits order information to the plurality of fabricator terminals 200B in step S110, the order information receiving unit 110 waits to receive order information from the fabricator terminals 200B (step S111). The order information receiving unit 110 determines whether the received order information has reached a certain number (step S112). If the number of order information has not reached a certain number (step S112: NO), the order information receiving unit 110 determines whether a certain period of time has passed since the date when the order information was transmitted in step S110 (step S113). . If a certain period of time has not passed since the order information was sent (step S113: NO), the process returns to step S111 and waits for the order information to be received.

On the other hand, if the number of received order information reaches a certain number (step S112: YES) or if a certain period of time has passed from the date of transmitting the order information (step S113: YES), the candidate presentation unit 111 selects a plurality of received order information. Based on the order information and the information stored in the user database 102, the order price, distance from the location to the construction site, and evaluation score are calculated for each candidate fabricator related to the order information (step S114). The candidate presenting unit 111 extracts candidate fabricators whose total score is equal to or greater than a predetermined threshold value based on the calculated scores (step S115). The candidate presentation unit 111 extracts, from among the extracted candidate fabricators, the one with the highest order price score, the highest distance score, and the highest evaluation score as recommended fabricators ( Step S116). The candidate presentation unit 111 generates mutual estimate screen data based on the order information and evaluation information related to the recommended fabricator extracted in step S116, and transmits it to the orderer terminal 200A (step S117).

The notification unit 114 notifies the fabricator terminal 200B of the candidate fabricator not extracted in step S116 that the order cannot be accepted (step S118). Note that when the order information receiving unit 110 receives new order information after step S118, the notification unit 114 notifies the fabricator terminal 200B, which is the source of the order information, that the order cannot be accepted, regardless of the content. .

When the receiving unit 201 of the orderer terminal 200A receives the quotation screen data, the display control unit 202 causes the display device to display a quotation screen as shown in FIG. This allows the orderer to select a fabricator from the viewpoints of order price, distance from the location to the construction site, and evaluation. When the orderer presses one of the ordering buttons shown in FIG. 5 associated with the selected fabricator, the transmitter 204 transmits selection information including information on the selected fabricator to the server 100.

The candidate selection unit 112 receives selection information from the orderer terminal 200A (step S119). The notification unit 114 notifies the fabricator terminal 200B of the contracted fabricator of the selection result indicated by the selection information (step S120). In other words, the notification unit 114 notifies the contract fabricator indicated by the selection information that the order has been received. In other words, a contract fabricator is an example of a contractor who receives orders for steel frames. On the other hand, the notification unit 114 notifies those recommended fabricators extracted in step S116 who are not selected as contract fabricators that the order cannot be accepted.

The contract presentation unit 113 transmits the guarantee contract information to the orderer terminal 200A and the fabricator terminal 200B of the contract fabricator (step S121). When the receiving section 201 of the orderer terminal 200A and the fabricator terminal 200B receives the guarantee contract information, the display control section 202 displays the received guarantee contract information on the display device. The orderer and the fabricator determine whether to conclude a guarantee contract with the platformer and transmit the determination result to the server 100. The contract presentation unit 113 receives guarantee acceptance information indicating whether to conclude a guarantee contract from the orderer terminal 200A and the fabricator terminal 200B (step S122). The requesting unit 105 determines whether each piece of guarantee acceptance/denial information indicates that a guarantee contract will be concluded (step S123). When indicating that a guarantee contract will be concluded (step S123: YES), the billing unit 105 executes a process of billing the user for a guarantee fee based on the account information of the user who concludes the compensation contract (step S124). Note that the contract presentation unit 113 may present information on a delivery company that will deliver the steel frame related to the order to the contract fabricator, and may accept an input as to whether or not to request the platformer to arrange the delivery company. Normally, the fabricator makes arrangements for the delivery company, so this can save the fabricator's time and effort.
In addition, the billing unit 105 executes billing processing for an introduction fee to the orderer based on the orderer's account information (step S125). Note that the billing unit 105 may bill the contract fabricator for fees in addition to or in place of the orderer. Furthermore, when receiving a request from a contracted fabricator to arrange a delivery company, the billing unit 105 may perform a process of billing the contracted fabricator for a delivery fee.

Thereafter, the contract fabricator manufactures the steel frame based on the contract with the orderer and delivers it to the orderer. Note that, when the steel frame is delivered from the contracted fabricator, the orderer may transmit information indicating whether or not the steel frame manufactured by the contracted fabricator is a nonconforming product to the server 100. When the server 100 receives information that the steel frame is nonconforming, the platformer investigates the delivered steel frame. If the steel frame is non-conforming and a guarantee contract has been concluded, the platform will fulfill the guarantee obligation in accordance with the guarantee contract. Once all steel has been delivered, the contract fabricator estimates the actual quantity of steel. The input unit 203 of the fabricator terminal 200B accepts the input of the actual quantity, and the transmitting unit 204 transmits actual performance information indicating the input actual quantity to the server 100.

The settlement processing unit 115 of the server 100 receives performance information from the fabricator terminal 200B (step S126). The settlement processing unit 115 determines whether the error between the actual quantity indicated by the actual performance information and the calculated quantity calculated by the calculating unit 107 exceeds a predetermined value (step S127). If the error between the actual quantity and the calculated quantity exceeds a predetermined value (step S127: YES), the settlement processing unit 115 generates settlement information based on the official quotation information and error received in step S111, and sends the settlement information to the orderer terminal. 200A (step S128). On the other hand, if the error between the actual quantity and the calculated quantity does not exceed the predetermined value (step S127: NO), the settlement processing unit 115 notifies the fabricator terminal 200B that the steel frame will not be settled (step S129).

The evaluation reception unit 116 receives input of individual evaluation information indicating the evaluation of the contracted fabricator from the orderer. The evaluation reception unit 116 also receives input of individual evaluation information indicating the orderer's evaluation from the contract fabricator (step S130). The evaluation reception unit 116 updates the evaluation information of the orderer and the contract fabricator stored in the user database 102 based on the received individual evaluation information (step S131).
