Description

The present invention relates to a server, a program, and an order mediation method.

When general contractors and other construction companies procure steel frames for use in buildings, they ask fabricators to manufacture the steel frames. Requests for steel frame manufacturing are usually made before official drawings are prepared for quotation, so fabricators reserve future manufacturing schedules in advance based on the details of the request.

JP 2005-174064 A

However, because manufacturing schedules are frequently changed due to delays in construction projects, etc., fabricators are likely to have busy and slow seasons. In addition, when a fabricator in a local community cannot secure a manufacturing schedule, a construction company has a hard time finding a fabricator to order from.
An object of the present invention is to provide a server, a program, and an order intermediation method that can act as an intermediary between an orderer of a steel structure and a fabricator.

According to one aspect of the present invention, a server communicates with an orderer ordering a small lot of steel beams weighing less than 300 tons and a plurality of fabricators that manufacture the steel beams via a network, and is equipped with an order information receiving unit that receives order information indicating an order for the steel beams from the orderer, a characteristic information acquiring unit that acquires project characteristic information indicating characteristics of a project in which the steel beam corresponding to the order information is used and fabrication characteristic information indicating each of the plurality of fabricators, a selecting unit that selects a plurality of recruited fabricators from the plurality of fabricators based on at least one of the project characteristic information and the fabrication characteristic information regardless of the respective locations of the plurality of fabricators, an order information transmitting unit that transmits the order information to the plurality of recruited fabricators selected by the selecting unit, an order information receiving unit that receives order information indicating an acceptance of the order indicated by the order information from a plurality of candidate fabricators that are some of the plurality of recruited fabricators, and a candidate presenting unit that presents at least a portion 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 act as an intermediary between the customer of the steel structure and the fabricator.

First Embodiment
<<Configuration of Steel Order System 1>>
Hereinafter, the 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 frame between steel frame orderers such as construction companies and trading companies and fabricators that manufacture the steel frame. A small lot of steel frame refers to steel frame weighing less than 300 tons. The steel frame ordering system 1 includes a server 100, multiple orderer terminals 200A, and multiple fabricator terminals 200B. The server 100 is operated by a platformer. The orderer terminal 200A is a terminal device 200 owned by an orderer and operated by the orderer. The fabricator terminal 200B is a terminal device 200 owned by a fabricator and operated by the fabricator. The server 100 communicates with the orderer terminal 200A and the fabricator terminal 200B via a network. The steel frame ordering system 1 accepts registrations of orderers and fabricators regardless of their locations. In other words, the steel structure ordering system 1 acts as an intermediary between fabricators in a wide area (e.g., nationwide) and customers in a wide area (e.g., nationwide).

<<Outline of Mediation Procedure>>
FIG. 2 is a schematic sequence diagram showing the flow of intermediation by the steel frame ordering system 1 according to the first embodiment.
The orderer operates the orderer terminal 200A to transmit order information for steel frames to the server 100 (step S1). The order information includes at least drawings and quotation conditions used to calculate the quantity of steel frames. The initial order information is usually transmitted before the building request is accepted in order to prepare a quotation to be used in price negotiations with the building client. Therefore, the drawings included in the initial order information are usually rough estimate drawings.

When the server 100 receives the order information, it 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 fee for the steel frame related to the order information (step S2). The server 100 transmits the generated quotation information to the orderer terminal 200A (step S3). In other words, since the server 100 creates quotation information based on the rough estimate drawings, the fabricator does not need to create quotation information based on the rough estimate drawings. The orderer can obtain quotation information without deciding which fabricator to contract with, so the freedom to choose a fabricator is ensured. Furthermore, if the drawings included in the order information are rough estimate drawings, 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.

Each time the orderer updates the drawings, he/she operates the orderer terminal 200A to update the order information and transmits it to the server 100 (step S4). The server 100 generates quotation information based on the received order information (step S5) and transmits it to the orderer terminal 200A (step S6). Each time the server 100 transmits quotation information to the orderer terminal 200A, it charges the orderer a fee for generating the quotation information. After that, when the orderer receives a request for a building from the client and the official drawings are completed, the orderer operates the orderer terminal 200A to transmit the order information, including the official drawings, to the server 100 (step S7).

When the server 100 receives the order information, it 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 quotation information to a fabricator that has been registered in advance (step S9). A fabricator must pay an annual fee to register with the steel frame ordering system 1. A fabricator can view the order information and quotation 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 quotation information. If the fabricator does not accept the order, it leaves the quotation information without taking any action. On the other hand, if the fabricator wishes to accept the order, the fabricator operates the fabricator terminal 200B to modify the unit price included in the presented quotation information to the unit price desired by the fabricator (step S10), and transmits the order information including the modified quotation information to the server 100 (step S11). In other words, the fabricator does not need to calculate the quantity of steel from the drawing, and can generate quotation information by simply modifying the unit price of the steel. Therefore, even if the fabricator misses the order for the order information, there is little disadvantage to using the steel ordering system 1 because there is little work to be done. Note that in small-lot steel transactions, the ratio of labor costs to material costs is large, so the unit price of steel is likely to vary depending on the fabricator.

When the server 100 receives order information from multiple fabricators (candidate fabricators), it extracts fabricators with good reviews, fabricators located close to the construction site, and fabricators with low estimated prices from among the fabricators that have received the order information, as fabricators to recommend to the customer (step S12). The server 100 presents the order information of the extracted fabricators, together with the fabricator's reviews, on the customer 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 selected as the order recipient (step S14). The server 100 notifies the fabricator terminal 200B of the selected fabricator that the order has been confirmed (step S15). At this time, the server 100 presents the guarantee contract provided by the platform to the orderer and the fabricator, and accepts input as to whether or not to enter into the guarantee contract. Upon deciding on the order recipient, the server 100 charges the orderer a brokerage fee.

Fabricators can receive orders only after the official drawings are completed, so the time from order to start of steel frame manufacturing can be shorter than if orders were received at the time of rough drawings. This allows fabricators to reduce schedule fluctuations. Also, fabricators can accept orders for steel frame manufacturing that can be started immediately during off-seasons.
After that, when the delivery of the steel frame by the fabricator is completed, the server 100 receives the settlement information of the fee from the fabricator terminal 200B as necessary (step S16), and transmits the settlement information to the orderer terminal 200A (step S17). This completes the commercial transaction of the steel frame between the orderer and the fabricator. The ownership of the steel frame is directly transferred between the fabricator and the orderer, and the platform operator operating the server 100 does not receive the 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). This causes the server 100 to update the evaluation information of the orderer and the fabricator.

As described above, according to the steel structure ordering system 1 of the first embodiment, the period from receipt of an order to the start of production is short, so fabricators can reduce the occurrence of off-seasons. Furthermore, according to the steel structure ordering system 1, a customer can easily select a fabricator to place an order with from fabricators in a wide area (e.g., nationwide).

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

The registration reception unit 101 accepts registrations for use of the steel structure ordering system 1 from the orderer terminal 200A and the fabricator terminal 200B. For example, the registration reception unit 101 accepts input of registration information including the company name, location, name of person in charge, classification as orderer or fabricator, account information, email address, and password. The registration reception unit 101 records the input registration information in the user database 102. The account information may indicate an account for a credit card, bank, or payment service. The registration reception unit 101 displays the rules for use of the steel structure ordering system 1 on the input screen for the registration information. Examples of the rules for use include rules for steel structure settlement and problem solving rules. Examples of the rules for steel structure settlement include accepting settlement when the error between the steel structure quantity related to the rough estimate and the actual quantity exceeds a specified value, and not accepting settlement when the error does not exceed the specified value.

The user database 102 stores the registration information, the registration status of the user related to the registration information, the evaluation information, and the payment status in association with each other. The registration status can be either "unregistered" or "registered." For example, the platformer operating the server 100 surveys the user when the user registers, evaluates the user, and records evaluation information indicating the evaluation result in the user database 102. The evaluation information may be expressed, for example, by a numerical value indicating a five-point evaluation. The evaluation information may also include a character string explaining the characteristics of the user. The payment status indicates whether or not the user has paid the annual membership fee. Note that an orderer is registered when the platformer confirms the user registration information after the user inputs the registration information. On the other hand, a fabricator is registered when the platformer confirms the user registration information after the user inputs the registration information and the annual membership fee is paid. Since the orderer does not pay the annual membership fee, the payment status for the orderer may be NULL.

The billing section 105 bills users of the steel structure ordering system 1 for usage fees.
Specifically, the billing unit 105 bills fabricators whose user registration information is registered in the user database 102 for annual membership fees. When the rough estimate sending unit 108 sends rough estimate information to an orderer, the billing unit 105 bills the orderer for a rough estimate preparation fee. When the orderer decides on a fabricator to order steel beams from, the billing unit 105 bills the orderer for an introduction fee. When the user concludes a warranty contract presented by the contract presentation unit 113, the billing unit 105 bills the user for a guarantee fee.
The billing section 105 generates billing information based on, for example, the account information recorded in the user database 102, and executes billing processing.

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

The setting unit 104 displays an input screen for steel frame order information on the orderer terminal 200A in response to an 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. The input screen includes an input form for inputting the project name, the location of the construction site, the construction period, the start date of construction, order acceptance conditions, quotation conditions, drawings, and a classification as to whether the drawings are rough estimate drawings or official drawings. The quotation conditions include, for example, drawing conditions, material conditions, processing conditions, rust prevention conditions, evaluation management conditions, on-site response conditions, document conditions, and the like. Examples of drawing conditions include whether or not a working drawing needs to be created, whether or not a match number drawing needs to be created, and whether or not a temporary drawing needs to be created. Examples of material conditions include the type of steel frame member, whether or not material procurement is required, and whether or not a manufacturer is specified. Examples of processing conditions include whether or not machining is performed, whether or not embedded metal fittings are used, and whether or not bending is performed. Examples of rust prevention conditions include the type of base treatment, whether or not undercoating is performed, and whether or not special painting is performed. Examples of evaluation management conditions include whether or not various on-site inspections are required. Examples of on-site conditions include whether or not matching numbers are required, whether or not scaffolding work is required, and whether or not blacksmithing work is required. Examples of document conditions include whether or not various guidelines, plans, and reports are required. Estimation conditions may be displayed selectably using, for example, check boxes or pull-down menus. Order conditions indicate the conditions of fabricators who can accept orders for the creation of steel structures. Order conditions indicate, for example, the grade or evaluation of the fabricator. Estimation conditions may also be input using an interactive input system such as a chatbot.
The drawings may be two-dimensional drawings represented by bitmap data or vector data, or three-dimensional drawings represented by CAD (Computer Aided Design) data or BIM (Building Information Modeling) data.

The order information receiving unit 106 receives the order information input by the orderer terminal 200A. If the classification of the drawings included in the order information as either rough estimate drawings or formal drawings indicates that the drawings are formal 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 accepts confirmation of the order information from the orderer.

The calculation unit 107 calculates the quantity and unit price of each type of steel frame based on the drawings and estimate conditions included in the order information. For example, the calculation unit 107 calculates the quantity and unit price of each type of steel frame in the following procedure.
The calculation unit 107 estimates detailed parts from the drawings, and calculates the quantity of each type of steel frame based on the estimated detailed parts. The calculation unit 107 calculates the quantity of each type of steel frame using a model that takes, for example, material conditions included in the drawings and the estimation conditions as input and outputs the quantity of each type. The calculation unit 107 estimates the welding amount of the steel frame based on the determined quantity of each type of steel frame. The calculation unit 107 estimates the processing difficulty of the steel frame from the estimated welding amount, the weight of the steel frame per piece, and the processing conditions. The calculation unit 107 calculates the unit price of each type of steel frame based on the market price of the steel frame, the processing difficulty, and the estimation conditions.
The rough estimate sending unit 108 generates rough estimate information based on the quantity and unit price of each type of steel frame calculated by the calculation unit 107, and sends it to the orderer terminal 200A that sent the order information.

When the classification of the drawings included in the order information is a formal drawing, the order information transmission unit 109 transmits the order information and the rough estimate information indicating the quantity and unit price of each type of steel frame calculated by the calculation unit 107 to the fabricator stored in the user database 102. The rough estimate information is represented, for example, by CSV data. For example, the order information transmission unit 109 may send an email with the order information attached to the fabricator's email address, or may send an email containing a URL for accessing the order information viewing screen to the fabricator's email address. In addition, the order information transmission unit 109 may transmit the 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 from the fabricator terminal 200B, which indicates a desire to receive an order for the steel frame indicated by the order information. The order information includes formal quotation information. The formal quotation information is data in which the fabricator has rewritten the unit price portion of the rough quotation information sent by the order information sending unit 109. In other words, the formal quotation information is an example of unit price correction information for correcting the unit price calculated by the calculation unit 107. The formal quotation information is also 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 is unable to accept orders due to a busy season will not send order information. Hereinafter, the fabricator that sent the order information is also referred to as a candidate fabricator.

When a certain number of pieces of order information have been received by the order information receiving unit 110, or when a certain period of time has passed since the order information was received, the candidate presentation unit 111 extracts three recommended fabricators from among the multiple candidate fabricators based on the multiple pieces of received order information and information stored in the user database 102. For example, the candidate presentation unit 111 extracts the recommended fabricators in the following procedure.
The candidate presentation unit 111 converts the order price indicated in the formal quotation information included in the order information, the distance from the fabricator's location to the construction site, and the fabricator's evaluation into scores. The lower the order price, the higher the score, the shorter the distance from the location to the construction site, and the higher the fabricator's evaluation. The score may be calculated, for example, by standard deviation using the candidate fabricators as a population. The candidate presentation unit 111 extracts, as recommended fabricators, the fabricators with the highest order price score, the highest distance score, and the highest evaluation score from among the candidate fabricators whose total score is equal to or greater than a predetermined threshold value, or the candidate fabricators whose scores are within a predetermined number of the top scores.
In other words, the candidate presentation unit 111 extracts, from among multiple candidate fabricator information, candidate fabricator information relating to candidate fabricators located closer to the construction site than the other candidate fabricators, candidate fabricator information relating to candidate fabricators with lower order prices than the other candidate fabricators, and candidate fabricator information relating to candidate fabricators with higher ratings than the other candidate fabricators.

The candidate presentation unit 111 sends a comparative quotation screen to the orderer terminal 200A, which presents the order information and evaluation information of the extracted recommended fabricators in a comparative manner. FIG. 5 is a diagram showing an example of the comparative quotation screen according to the first embodiment. As shown in FIG. 5, the comparative quotation screen displays the locations, evaluations, and order prices of the three recommended fabricators side by side. In addition, the unit prices and amounts offered by the three recommended fabricators for each item are displayed side by side for the order prices.

The candidate selection unit 112 accepts the selection of a contract fabricator from among the three recommended fabricators to order the steel frame 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 competitive quote screen shown in FIG. 5.

The notification unit 114 notifies each candidate fabricator of whether or not they will accept the steel frame order. Specifically, when the candidate presentation unit 111 extracts three recommended fabricators, the notification unit 114 notifies the candidate fabricators that were not extracted that they will not be able to accept the order. In addition, when the candidate selection unit 112 accepts the selection of a contract fabricator, the notification unit 114 notifies the recommended fabricators that were not selected that they will not be able to accept the order. In addition, when the candidate selection unit 112 accepts the selection of a contract fabricator, the notification unit 114 notifies the recommended fabricators that they will be able to accept the order.

When a contract fabricator is selected by the candidate selection unit 112, the contract presentation unit 113 presents the guarantee contract information for the order to the orderer and the contract fabricator. A guarantee contract is a contract concluded between the user, who is the orderer or contract fabricator, and the platformer, and is a contract under which the platformer is obligated to make payment when a debt is not paid between the users. The contract presentation unit 113 accepts whether or not to conclude a guarantee contract indicated by the compensation contract information presented by the user.

The settlement processing unit 115 receives actual results information indicating the actual quantity of steel beams fabricated from the fabricator terminal 200B. If the difference between the actual quantity indicated by the actual results information and the quantity calculated by the calculation unit 107 exceeds a predetermined value, the settlement processing unit 115 accepts input of settlement information indicating the fee after settlement from the fabricator terminal 200B. On the other hand, if the difference between the actual quantity indicated by the actual results information and the quantity calculated by the calculation unit 107 does not exceed the predetermined value, the settlement processing unit 115 does not accept settlement information.

The evaluation receiving unit 116 receives input of individual evaluation information indicating the evaluation of the contract fabricator from the customer. The evaluation receiving unit 116 also receives input of individual evaluation information indicating the customer's evaluation from the contract fabricator. The individual evaluation information may be expressed, for example, by a numerical value indicating a five-point scale. The evaluation information may also include a character string that describes the characteristics of the user. The evaluation receiving unit 116 updates the evaluation information stored in the user database 102 based on the received individual evaluation information. For example, the evaluation receiving 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 receiving unit 116 adds the character string included in the individual evaluation information to the character string related to the evaluation information.

Configuration of terminal device 200
6 is a block diagram showing the configuration of a 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 unit 201, a display control unit 202, an input unit 203, and a transmitting unit 204. The receiving unit 201 receives data from the server 100. The display control unit 202 displays the information received by the receiving unit 201 from the server 100 on a display device such as an LCD panel or a touch panel. The input unit 203 accepts input operations by a user via an input device such as a keyboard, a mouse, or a 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 an orderer operates the orderer terminal 200A to access 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 the input screen data for order information from the server 100, the display control unit 202 causes the display device to display an input screen for order information as shown in FIG. 4. The input unit 203 of the orderer terminal 200A accepts input of order information from the orderer. When the orderer operates to press the quote request button on the input screen, the transmitting unit 204 of the orderer terminal 200A transmits the order information to the server 100.

When the order information receiving unit 106 of the server 100 receives the order information (step S102), it determines whether the classification of the order information, whether it is an approximate drawing or a formal drawing, indicates that it is a formal drawing (step S103).

If the category indicates a rough estimate drawing (step S103: NO), the calculation unit 107 calculates the quantity and unit price for each type of steel frame based on the drawing and estimate conditions included in the order information received in step S102 (step S104). The rough estimate sending unit 108 generates rough estimate information based on the quantity and unit price for each type of steel frame calculated in step S104 (step S105). The rough estimate sending unit 108 sends 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 the fee related to the generation of the 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 if the order information category indicates rough drawings, 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 a formal drawing (step S103: YES), the calculation unit 107 calculates the quantity and unit price for each type of steel frame based on the drawing and the estimate conditions included in the order information received in step S102 (step S108). The order information transmission unit 109 generates rough estimate information based on the quantity and unit price for each type of steel frame calculated in step S108 (step S109). The order information transmission unit 109 transmits the generated rough estimate information, the order information received in step S102, and the evaluation information of the orderer to a fabricator whose registration status in the user database 102 indicates registration and that satisfies the order acceptance conditions included in the order information (step S110). At this time, the order information transmission unit 109 may also transmit a shop drawing generated based on the formal drawing to the fabricator together with the order information. For example, the server 100 accepts an upload of a shop drawing created by the platformer and transmits the uploaded shop drawing to the fabricator. This means that fabricators no longer need to create shop drawings for jobs that do not have a guaranteed order.

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 he wishes to accept the order for the steel frame indicated by the order information. If the fabricator wishes to accept the order, he generates formal estimate information by modifying the unit price indicated by the rough estimate information. The transmitting unit 204 of the fabricator terminal 200B transmits the order information including the formal estimate information to the server 100.

When the server 100 transmits order information to multiple 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 received order information has not reached the certain number (step S112: NO), the order information receiving unit 110 determines whether a certain period of time has passed since the date on which the order information was transmitted in step S110 (step S113). If the certain period of time has not passed since the transmission of the order information (step S113: NO), the process returns to step S111 and waits to receive order information.

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 since the date of sending the order information (step S113: YES), the candidate presentation unit 111 calculates the order price, the distance from the location to the construction site, and the evaluation score for each candidate fabricator related to the order information based on the received multiple order information and the information stored in the user database 102 (step S114). Based on the calculated scores, the candidate presentation unit 111 extracts candidate fabricators whose total score is equal to or greater than a predetermined threshold (step S115). From the extracted candidate fabricators, the candidate presentation unit 111 extracts the fabricator with the highest order price score, the highest distance score, and the highest evaluation score as a recommended fabricator (step S116). The candidate presentation unit 111 generates comparative quotation 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 that was not extracted in step S116 that the order cannot be accepted (step S118). If the order information receiving unit 110 receives new order information after step S118, the notification unit 114 notifies the fabricator terminal 200B that sent the order information that the order cannot be accepted, regardless of the content of the new order information.

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

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

The contract presentation unit 113 transmits the warranty contract information to the orderer terminal 200A and the fabricator terminal 200B of the contract fabricator (step S121). When the receiving unit 201 of the orderer terminal 200A and the fabricator terminal 200B receives the warranty contract information, the display control unit 202 displays the received warranty contract information on the display device. The orderer and the fabricator judge whether or not to conclude a warranty contract with the platformer, and transmit the judgment result to the server 100. The contract presentation unit 113 receives warranty acceptance/rejection information indicating whether or not to conclude a warranty contract from the orderer terminal 200A and the fabricator terminal 200B (step S122). The billing unit 105 judges whether or not each warranty acceptance/rejection information indicates that a warranty contract is to be concluded (step S123). If it indicates that a warranty contract is to be concluded (step S123: YES), the billing unit 105 executes a process of billing the user for the warranty fee based on the account information of the user who concludes the compensation contract (step S124). The contract presentation unit 113 may present the contract fabricator with information on a delivery company that will deliver the steel frame related to the order, and may receive an input as to whether or not to request the platformer to arrange for the delivery company. Normally, the fabricator arranges for the delivery company, so this can save the fabricator time.
The billing unit 105 also executes a process of billing the customer for the referral fee based on the customer's account information (step S125). The billing unit 105 may also execute a process of billing the contract fabricator for the fee in addition to or instead of the customer. The billing unit 105 may also execute a process of billing the contract fabricator for the delivery fee when it receives a request from the contract fabricator to arrange for a delivery company.

Then, the contract fabricator fabricates the steel frame based on the contract with the customer and delivers it to the customer. When the steel frame is delivered by the contract fabricator, the customer may send information to the server 100 indicating whether the steel frame fabricated by the contract fabricator is non-conforming. If the server 100 receives information that the steel frame is non-conforming, the platformer will investigate the delivered steel frame. If the steel frame is non-conforming and a warranty contract has been concluded, the platformer will fulfill the warranty obligation in accordance with the warranty contract. Once delivery of all the steel frame is complete, the contract fabricator will add up the actual quantity of the steel frame. The input unit 203 of the fabricator terminal 200B accepts the input of the actual quantity, and the transmission unit 204 transmits actual information indicating the input actual quantity to the server 100.

The settlement processing unit 115 of the server 100 receives the actual results 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 results information and the calculated quantity calculated by the calculation unit 107 exceeds a predetermined value (step S127). If the error between the actual quantity and the calculated quantity exceeds the predetermined value (step S127: YES), the settlement processing unit 115 generates settlement information based on the official estimate information received in step S111 and the error, and sends it 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 receiving unit 116 receives input of individual evaluation information indicating the evaluation of the contract fabricator from the customer. The evaluation receiving unit 116 also receives input of individual evaluation information indicating the customer's evaluation from the contract fabricator (step S130). The evaluation receiving unit 116 updates the evaluation information of the customer and the contract fabricator stored in the user database 102 based on the received individual evaluation information (step S131).

<Action and Effects>
Thus, according to the steel frame ordering system 1 of the first embodiment, the server 100 receives order information from an orderer and transmits it to a plurality of fabricators. The server 100 also receives information from a plurality of candidate fabricators, which are at least a part of the plurality of fabricators, and presents the information of the candidate fabricators to the orderer. This allows the orderer to know which fabricators can order steel frames from among the wide-area (e.g., nationwide) fabricators registered in the steel frame ordering system 1. Also, for example, a fabricator can receive steel frame orders from a wide-area (e.g., nationwide) orderer registered in the steel frame ordering system 1. In other words, according to the steel frame ordering system 1, a fabricator can receive steel frame orders during the off-season, and the orderer can easily find a fabricator to request.

Furthermore, according to the steel frame ordering system 1 of the first embodiment, the server 100 presents to the orderer, among the multiple candidate fabricator information received from the multiple candidate fabricators, those that are located closer to the construction site than the other candidate fabricators, those that have lower order prices than the other candidate fabricators, and those that are more highly rated than the other candidate fabricators. This allows the orderer to select a fabricator based on the different perspectives of price, location, and rating.

Furthermore, according to the steel structure ordering system 1 of the first embodiment, the server 100 accepts settings of order conditions that must be met by fabricators who receive orders from customers, and transmits order information to fabricators among multiple fabricators that meet the order conditions. This allows the steel structure ordering system 1 to present fabricators that meet the requirements of the customer, and also prevents unnecessary work from being generated by fabricators that do not meet the order conditions.

Furthermore, according to the steel frame ordering system 1 of the first embodiment, the server 100 calculates the quantity and unit price of the steel frame based on the drawings that include the order information. This allows the server 100 to automatically generate rough estimate information.

Furthermore, according to the steel structure ordering system 1 of the first embodiment, the order information includes quotation condition information indicating the quotation conditions for the steel structure, and the server 100 calculates the quantity and unit price using the quotation condition information. This allows the steel structure ordering system 1 to prevent the estimated quantity and unit price of the steel structure from becoming far from the actual value due to information leaks.

Furthermore, according to the steel structure ordering system 1 of the first embodiment, the server 100 accepts settlement based on the quantity of steel structure automatically calculated from the fabricator terminal 200B. This prevents the fabricator from incurring losses even if the estimated quantity differs from the actual quantity. The server 100 also accepts settlement when the error between the automatically calculated quantity of steel structure and the actual quantity exceeds a specified value, and does not accept settlement when the error does not exceed the specified value. This allows the steel structure ordering system 1 to prevent the customer from having to go through the trouble of settlement based on small errors.

The steel frame ordering system 1 according to the first embodiment receives order information including formal quotation information in which the unit price automatically calculated from the fabricator terminal 200B has been corrected. This allows the fabricator to easily generate quotation information by correcting the unit price without the need to calculate the quantity of steel frames based on the drawings.

In addition, according to the steel structure ordering system 1 of the first embodiment, the server 100 transmits the order information to multiple fabricators when the drawings included in the order information are formal drawing information, and does not transmit the order information to a fabricator when the drawings are approximate drawing information. This eliminates the need for fabricators to secure an uncertain schedule before receiving an order for steel structure fabrication.

In addition, according to the steel frame ordering system 1 of the first embodiment, the server 100 determines the amount of welding for the steel frame based on the drawing information, estimates the processing difficulty of the steel frame, and calculates the unit price of the steel frame based on the processing difficulty. This allows the server 100 to calculate the unit price appropriately according to the type of steel frame.

Furthermore, according to the steel structure ordering system 1 of the first embodiment, the server 100 charges a fee to the orderer when the quantity and unit price are automatically calculated. The server 100 also accepts payment of an annual membership fee from the fabricator, and transmits order information to multiple fabricators that have paid the annual membership fee. This allows the steel structure ordering system 1 to appropriately generate revenue for the platform operator.

Furthermore, according to the steel frame ordering system 1 of the first embodiment, the server 100 accepts confirmation of order information from the orderer and transmits the order information confirmed by the orderer to the fabricator terminal 200B. This allows the fabricator to obtain order information at the stage when the design is complete, rather than at the conceptual or planning stage. By receiving an order for steel frames at the stage when the design is complete, the period from receiving the order to starting production of the steel frames can be shortened. In other words, the fabricator can receive orders for steel frames that can be produced immediately during the off-season.

In addition, according to the steel structure ordering system 1 of the first embodiment, the server 100 accepts fabricator evaluations from the orderer, and accepts the orderer's evaluations from the fabricator. The server 100 also presents the orderer with evaluation information along with information on candidate fabricators. This allows the orderer to select a fabricator while referring to past evaluations.

Furthermore, according to the steel structure ordering system 1 of the first embodiment, the server 100 presents, together with the candidate fabricator information, quotation information sent from the fabricator indicated by the candidate fabricator information. This allows the orderer to select a fabricator by referring to the presented quotation information. In particular, according to the first embodiment, the server 100 presents quotation information for multiple candidate fabricators in a comparable manner. This allows the orderer to obtain competitive quotations from the candidate fabricators.

In addition, according to the steel structure ordering system 1 of the first embodiment, when the server 100 receives from the orderer a selection of a contract fabricator from among multiple candidate fabricators to order steel structures, the server 100 presents warranty contract information and receives a decision as to whether or not to enter into the warranty contract. This allows the orderer and the fabricator to avoid credit risk.

In addition, according to the steel structure ordering system 1 of the first embodiment, the server 100 notifies those of the multiple candidate fabricators whose candidate fabricator information was not presented to the orderer that they were not selected by the orderer. This allows the fabricators whose candidate fabricator information was not presented to the orderer to immediately know that they were unable to accept the order, shortening the wait time for the order to be fulfilled.

The steel frame ordering system 1 according to the first embodiment also handles small-lot steel frame transactions of less than 300 tons. Since the ratio of labor costs to material costs is high for small-lot steel frames, the unit price of the steel frame is likely to vary depending on the fabricator. Therefore, by handling small-lot steel frame transactions, the steel frame ordering system 1 can present the customer with a variety of fabricator options.

In addition, the entity that operates the server 100 of the steel structure ordering system 1 according to the first embodiment does not take over ownership of the steel structure. This prevents the platform operator from bearing inventory risk.

Next, the selection of recruited fabricators to which order information is to be sent in the second embodiment will be described. The selection unit 122 selects multiple recruited fabricators from among the multiple fabricators, regardless of the locations of each of the multiple fabricators. The selection unit 122 selects multiple recruited fabricators based on the case characteristic information and fabrication characteristic information acquired as a result of processing by the characteristic information acquisition unit 121. First, the selection unit 122 identifies (cuts off) fabricators from among the multiple fabricators that are not to be used as destinations for sending order information. The cutoff includes a cutoff based on fabrication capacity information (first cutoff) and a cutoff based on fabrication area information (second cutoff). Note that, although both the first cutoff and the second cutoff are performed in this embodiment, only one of them may be performed.

First, the cutoff based on fab capacity information (first cutoff) will be described. The selection unit 122 cuts off fabricators based on the case capacity information in the case characteristic information and the fab capacity information in the fab characteristic information. Specifically, the selection unit 122 compares the items indicated by the case capacity information in the case characteristic information ("special materials," "corrosion prevention," and "crane capacity") with the items indicated by the fab capacity information in the fab characteristic information of each of the multiple fabricators ("special materials," "corrosion prevention," and "crane capacity"). By comparing each item for each fabricator, the selection unit 122 cuts off fabricators that do not meet at least one of the items.

For example, assume that "special materials" is "1," "corrosion prevention" is "1," and "crane capacity" is "1" as shown in the case capacity information in FIG. 11. Also assume that "special materials" is "1," "corrosion prevention" is "1," and "crane capacity" is "0" as shown in the fabrication capacity information in FIG. 12. In this case, the fabricator's "crane capacity" is not sufficient for the case, so the fabricator will be eliminated.

Next, the cutoff based on the fabrication area information (second cutoff) will be described. The selection unit 122 cuts off the fabricator when the address of the job obtained from the order information is not included in the area indicated by the scaffolding and blacksmith network. The selection unit 122 cuts off the fabricator when the address of the job obtained from the order information is not included in the area indicated by the on-site welding network. Note that scaffolding and blacksmiths are not necessarily arranged by the fabricator, but may be arranged by the orderer himself. In this case, the selection unit 122 does not cut off based on the scaffolding and blacksmith network. Similarly, on-site welders may be arranged by the orderer himself. In this case, the selection unit 122 does not cut off based on the on-site welding network. Note that information indicating whether the orderer arranges scaffolding and blacksmiths is included in the order information.

Next, the calculation of the matching point by the calculation unit 107 will be described. The calculation unit 107 calculates the matching point based on the case characteristic information and the fab characteristic information. The matching point is a numerical value indicating the degree of compatibility between the case and each of the multiple fabricators. The matching point includes a first matching point and a second matching point. First, the calculation of the first matching point will be described. For example, the fab application information (Figure 12) is used to calculate the first matching point.

As shown in FIG. 11, for example, the construction type is public construction, the property type is factory, the structure type is SRC construction, and the design office is a specific office. As shown in FIG. 12, the fab construction information has a score of "50", a warehouse has a score of "100", an SRC construction has a score of "50", and a specific office has a score of "50". In this case, the calculation unit 107 calculates a first matching point of "50+100+50+50=250" by adding up the scores of the fab construction information corresponding to the project construction information. The calculation unit 107 may calculate the first matching point by not only adding up but also multiplying, for example. The calculation unit 107 may also calculate the first matching point by weighting some of the scores by a coefficient according to the importance of each item.

The selection unit 122 selects multiple (e.g., 10) recruiting fabricators based on the first matching points calculated by the calculation unit 107. Specifically, the selection unit 122 selects multiple fabricators with high first matching points (above a threshold) as recruiting fabricators.

Next, the transmission of order information and the reception of order information will be described. The order information transmission unit 109 transmits order information to multiple recruited fabricators selected by the selection unit 122. The order information reception unit 110 receives order information indicating that the order indicated by the order information will be accepted from multiple candidate fabricators that are part of the multiple recruited fabricators.

Next, the presentation of information on fabricators to be traded to the orderer will be described. The candidate presentation unit 111 presents at least a portion of the candidate fabricator information indicating each of the candidate fabricators to the orderer. In this embodiment, the candidate presentation unit 111 presents the portion to the orderer based on information (item characteristic information and fab characteristic information) acquired by the result of processing by the characteristic information acquisition unit 121. For example, the candidate presentation unit 111 identifies a portion of the candidate fabricators based on the matching point (second matching point) calculated by the calculation unit 107 and presents it to the orderer. Specifically, the candidate presentation unit 111 identifies a portion of the candidate fabricators with a high second matching point (above a threshold) from among the multiple candidate fabricators and presents it to the orderer. For example, fab level information (see FIG. 12) is used to calculate the second matching point.

For example, as shown in FIG. 12, the fab level information may have a score of "100" for consolidation, a score of "30" for strictness, a score of "100" for quality, a score of "60" for flexibility, and a score of "60" for stockyard. In this case, the calculation unit 107 calculates the second matching point of "100+30+100+60+60=350" by adding up the scores. Note that the calculation of the second matching point is not limited to addition, and may be, for example, multiplication. The calculation unit 107 may also calculate the second matching point by weighting some of the scores, such as by multiplying them by a coefficient, according to the importance of each item.

In this way, in this embodiment, the second matching point is calculated based on the fab level information, while the first matching point is calculated based on the fab use information. That is, the two are calculated based on different information. In other words, the fabricators being recruited (at the stage of sending the order information) are selected based on the capabilities required for the building and the use of the steel frame, while some of the fabricators presented to the customer are selected based on the customer's preferences, such as their ability to organize and their level of strict adherence. For this reason, at the stage of presenting fabricators, it is possible to present to the customer fabricators that reflect the customer's preferences from among fabricators that meet certain conditions (fabricators that meet the first matching point). In other words, it is possible to present fabricators that are suitable for the customer.

Next, the control of the display of the orderer terminal 200A by the display control unit 123 will be described. The display control unit 123 displays the case characteristic information and the fab characteristic information on the display unit of the orderer terminal 200A. For example, the display control unit 123 displays the recruited fabricator information related to the recruited fabricator, the case characteristic information, and the fab characteristic information on the display unit in association with each other. The display control unit 123 also displays the matching points of each fabricator calculated by the calculation unit 107 in association with each of the multiple fabricators on the display unit. Here, an example screen of the orderer terminal 200A according to the second embodiment will be described with reference to FIG. 13 as an example.

Figure 13 is a diagram showing an example of a comparative quotation screen according to the second embodiment. As shown in Figure 13, the comparative quotation screen is displayed on the display unit 300 of the orderer terminal 200A. The comparative quotation screen is a screen displayed for each project. The comparative quotation screen displays multiple candidate fabricator information 310 (310a, 310b, 310c). Each candidate fabricator information 310 includes fab evaluation information 311 (311a, 311b, 311c). The fab evaluation information 311 represents the second matching point based on the fab level information (fab characteristic information) in four stages, further represented by the number of predetermined marks (★) (for example, 1 to 4). In addition, on the comparative quotation screen, the "factory production cost" shown in the item column 312 indicates the property type (factory) included in the project characteristic information. In other words, the comparative quotation screen displays the project characteristic information, the candidate fabricator information 310, and the fab evaluation information 311 as fab characteristic information in association with each other.

In addition, by accepting a predetermined screen switching operation from the purchaser on the comparative quotation screen, the display control unit 123 can display a screen corresponding to the accepted operation among fab capacity information, fab area information, and fab evaluation information (fab application information and fab level information). For example, when an operation to switch to the fab evaluation information screen is accepted, the display control unit 123 can display the fab evaluation information. Specifically, when an operation to switch to the fab level information screen is accepted, it is possible to display the fab level information (for example, consolidation ability "100", strict adherence level "30", etc.). This allows the purchaser to grasp the fab characteristic information in detail. Therefore, even if, for example, a fabricator with a low second matching point is displayed among the presented candidate fabricators, the purchaser can view a detailed screen of the fab evaluation information, etc. This allows, for example, a purchaser who places importance on consolidation ability to check the consolidation ability and select a fabricator to place an order with.

Figure 14 is a diagram showing an example of an estimate confirmation screen displayed on the orderer terminal 200A. The estimate confirmation screen shown in Figure 14 is transitioned, for example, by accepting a predetermined screen switching operation from the orderer on the comparative estimate screen shown in Figure 13. As shown in Figure 14, the display unit 300 of the orderer terminal 200A includes the project name (project name) and address as project characteristic information. In addition to the project name and address, it is also possible to display project use information and project capacity information on the display unit 300 by accepting a predetermined screen switching operation from the orderer. For example, when a switching operation to the project use information screen is accepted, the display control unit 123 can display the project use information, and specifically, it is possible to display the construction type, property type, structure type, and design office of the project. This allows the orderer to check the project use information.

The comparative quote screen shown in FIG. 13 and the quotation request screen shown in FIG. 14 can be displayed simultaneously on one screen. For example, the comparative quote screen and the quotation confirmation screen can be displayed side by side, or the other screen can be superimposed on one screen.

<<Operation of Steel Ordering System 1>>
15 is a flowchart showing the operation of the server 100 according to the second embodiment. When the order information receiving unit 106 receives order information including formal drawing information from the orderer terminal 200A (step S201), the characteristic information acquiring unit 121 acquires case characteristic information from the order information (step S202). The characteristic information acquiring unit 121 then extracts case capability information from the acquired case characteristic information (step S203), and acquires fabrication capability information corresponding to the case capability information for each fabricator from the user database 102 (step S204).

Then, the selection unit 122 performs a cut-off (first cut-off) of fabricators based on the case capacity information and the fab capacity information (step S205). Next, the characteristic information acquisition unit 121 extracts the address information of the case from the case characteristic information (step S206), and acquires fab area information (scaffolding/blacksmith network and on-site welding network) from the user database 102 for each fabricator after the first cut-off (step S207).

Then, the selection unit 122 performs a second cutoff of fabricators based on the address information and the fab area information (step S208). Next, the characteristic information acquisition unit 121 extracts project use information from the project characteristic information (step S209), and acquires fab use information from the user database 102 for each fabricator after the second cutoff (step S210).

Then, the calculation unit 107 calculates a first matching point based on the case use information and the fab use information, specifically by adding up each score of the fab use information corresponding to the case use information (step S211). Next, the selection unit 122 selects multiple (e.g., 10) recruited fabricators based on the first matching point (step S212). Then, the order information transmission unit 109 transmits order information to each of the fabricator terminals 200B of the multiple recruited fabricators (step S213).

The order information receiving unit 110 waits to receive order information from the fabricator terminal 200B (step S214). The order information receiving unit 110 determines whether the number of received order information has reached a certain number (e.g., 5) (step S215). If the number of order information has not reached the certain number (step S215: NO), the order information receiving unit 110 determines whether a certain period of time has passed since the order information was sent (step S216). If the certain period of time has not passed since the order information was sent (step S216: NO), the process returns to step S214 and waits to receive order information.

When a certain number of order information items have been received (step S215: YES), or when a certain period of time has passed since the order information was sent (step S216: YES), the characteristic information acquisition unit 121 acquires fabric level information from the user database 102 for each candidate fabricator that sent the order information (step S217).

Then, the calculation unit 107 calculates the second matching point by adding up each score of the fab level information (step S218). Next, the candidate presentation unit 111 identifies multiple (e.g., three) fabricators to which the competitive quotation screen data will be sent based on the second matching point (step S219). Then, the candidate presentation unit 111 generates competitive quotation screen data based on the order information related to the identified fabricators and sends it to the orderer terminal 200A (step S220). Furthermore, the notification unit 114 notifies the fabricator terminal 200B of the candidate fabricators that were not identified as the destination of the orderer that the order cannot be accepted (step S221), and the process proceeds to step S119 in FIG. 8.

<Action and Effects>
Thus, according to the steel frame ordering system 1 of the second embodiment, the server 100 transmits order information to a plurality of recruited fabricators selected from a plurality of fabricators regardless of their locations, receives order information from a plurality of candidate fabricators that are part of the plurality of recruited fabricators, and presents at least a part of the plurality of candidate fabricator information to the orderer. The server 100 also performs a process of selecting a plurality of recruited fabricators based on the case characteristic information (FIG. 11) and the fab characteristic information (FIG. 12), and a process of presenting the part to the orderer based on the case characteristic information and the fab characteristic information. As a result, even if there is no transaction record between the orderer and the fabricator, the most suitable fabricator can be presented by matching the case characteristic information and the fab characteristic information. Therefore, the orderer can select the most suitable fabricator to which the orderer will place the order. Thus, according to the second embodiment, it is possible to preferably mediate between the orderer of the steel frame and the fabricator.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the project characteristic information includes project capability information (FIG. 11) that indicates the capabilities of multiple fabricators and the capabilities required for the construction of the project. This makes it possible to exclude fabricators that do not have the capabilities required for the construction of the project from transactions with the orderer (first cutoff), and therefore makes it possible to present to the orderer suitable fabricators that have the capabilities required for the construction of the project.

In addition, according to the steel structure ordering system 1 of the second embodiment, the project characteristic information includes project use information (Figure 11) related to the use of the steel structure. This makes it possible to present the orderer with a suitable fabricator according to the use of the steel structure.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the fabrication characteristic information includes fabrication area information indicating the area where the project will be constructed and which area each of the multiple fabricators can handle. This makes it possible to exclude fabricators who work in areas that cannot handle the project from transactions with the orderer (second cut-off). Therefore, it is possible to present the orderer with suitable fabricators who work in areas that can handle the project.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the fabrication characteristic information includes fabrication evaluation information for each of a plurality of fabricators. This makes it possible to present highly rated fabricators to the customer.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the server 100 displays project characteristic information (project name and address in FIG. 14) and fabrication characteristic information (fab evaluation information 311 in FIG. 13) on the display unit 300. This makes it easier for the orderer to understand the degree of matching between the project and the fabricator, and can provide optimal support for the orderer in selecting a fabricator.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the server 100 displays candidate fabricator information 310 (FIG. 13) related to the candidate fabricators, the project characteristic information, and the fab characteristic information on the display unit 300 in association with each other. This makes it easier for the orderer to understand the reason why the fabricators are being presented based on the project characteristic information and the fab characteristic information. Therefore, it is possible to more appropriately support the orderer in selecting a fabricator.

Furthermore, according to the steel structure ordering system 1 of the second embodiment, the server 100 calculates the matching points (fab evaluation information 311 in FIG. 13) of multiple fabricators based on the project characteristic information and the fabrication characteristic information, and displays each matching point in association with multiple fabricators on the display unit 300. This makes it easier for the orderer to understand which fabricators are compatible with the project. Therefore, it is possible to more effectively support the orderer in selecting a fabricator.

<Modification of the second embodiment>
Next, modified examples of the second embodiment will be listed. In the following modified examples, the contents explained in the first and second embodiments will be omitted as appropriate. In addition, each of the following modified examples can be combined with the first and second embodiments.

<Variation 1>
In the above-described second embodiment, an example has been described in which the case characteristic information and the fab characteristic information are used in both the process related to the selection of a plurality of fabricators recruited by the selection unit 122 and the process related to the presentation of fabricator information to the orderer by the candidate presentation unit 111. In the first modified example, the case characteristic information and the fab characteristic information may be used in at least one of the processes related to the selection and the process related to the presentation. Even in this way, appropriate fabricators can be presented to the orderer by matching the case characteristic information with the fab characteristic information.

<Modification 2>
In the above-described second embodiment, an example was described in which a star mark was displayed as the fab evaluation information 311 on the comparative quotation screen displayed on the orderer terminal 200A. In the second modification, another aspect in which the fab evaluation information 311 is displayed instead of or in addition to the star mark will be described. In the second modification, the fab evaluation information 311 may be represented by a numerical value (e.g., "350") indicating the second matching point. Also, the fab evaluation information 311 may be represented by the first matching point. In this case, the first matching point may be represented in multiple stages by the number of predetermined marks (e.g., star marks), or may be represented by the numerical value indicating the first matching point. Even in this way, it becomes easier for the orderer to grasp the degree of matching between the project and the fabricator, and it is possible to favorably support the orderer in selecting a fabricator.

<Modification 3>
In the above-described second embodiment, an example in which the fab use information (FIG. 12) is used in the calculation of the first matching point has been described. In the third modification, an example in which other information is used in the calculation of the first matching point will be described. For example, the fab level information (FIG. 12) may be used instead of or in addition to the fab use information in the calculation of the first matching point. In addition, for example, the address information of the fabricator may be used as the fab use information in the calculation of the first matching point. The address of the fabricator is initially registered. The calculation unit 107 acquires the address of the fabricator and the address of the job, and obtains a score (for example, "50" or "100") according to the distance between the two. For example, the score may be set to "100" if the distance between the two is less than a predetermined distance, and "50" if the distance is equal to or greater than the predetermined distance. The calculation unit 107 may calculate the first matching point taking the score into consideration. In this way, it is possible to easily select a fabricator close to the location of the job as a recruited fabricator. Therefore, it is possible to present an appropriate fabricator to the customer.

<Modification 4>
In the above-described second embodiment, an example in which the fab level information (FIG. 12) is used in the calculation of the second matching point has been described. In the fourth modification, an example in which other information is used in the calculation of the second matching point will be described. For example, in the calculation of the second matching point, fab use information (FIG. 12) may be used instead of or in addition to the fab level information. In addition, in the calculation of the second matching point, for example, address information of the fabricator may be used as the fab level information. The address of the fabricator is initially registered. The calculation unit 107 acquires the address of the fabricator and the address of the job, and obtains a score (for example, "30", "60", or "100") according to the distance between the two. For example, the score may be "100" if the distance between the two is less than the first predetermined distance, "60" if the distance is equal to or greater than the first predetermined distance and less than the second predetermined distance, and "30" if the distance is equal to or greater than the second predetermined distance. Note that the first predetermined distance is a value smaller than the second predetermined distance. The calculation unit 107 may calculate the second matching points by taking the score into consideration. In this way, it is possible to easily present fabricators close to the location of the job as fabricators to be presented to the orderer. Therefore, it is possible to present an appropriate fabricator to the orderer.
