(Embodiment)
A contractor selection system, a contractor selection device, a contractor selection method, and a program according to an embodiment of the present disclosure will be described below with reference to FIGS. 1 to 6. FIG.

[System configuration]
First, with reference to FIG. 1, a schematic configuration of the construction contractor selection system according to the embodiment will be described. FIG. 1 is a block diagram showing a schematic configuration of a contractor selection system according to an embodiment of the present disclosure.

The construction contractor selection system in the embodiment shown in FIG. 1 is a system for selecting construction contractors. As shown in FIG. 1 , the construction company selection system 100 includes a candidate selection unit 11 , a transmission unit 12 and a determination unit 13 .

Then, the candidate selection unit 11 selects a candidate for the orderer (hereinafter simply referred to as "candidate") based on the construction information regarding the construction details and the contractor information for each construction contractor. Here, "ordering" means that the person in charge of the construction requester places an order for the construction work, and "orderer" is the contractor to whom the person in charge of the construction requester orders the construction work.

The transmitting unit 12 transmits the construction information to the selected candidates. The determination unit 13 determines the orderer based on the responses to the construction information from the candidates.

As described above, according to the construction contractor selection system 100, it is possible to select construction contractors (order contractors) without requiring selection work by the person in charge of ordering.

Next, with reference to FIGS. 2 to 4, the configuration and functions of the contractor selection system according to the embodiment will be described more specifically. FIG. 2 is a block diagram specifically showing the configuration of the contractor selection system according to the embodiment of the present disclosure. FIG. 3 is a diagram showing an example of construction information used in the embodiment. FIG. 4 is a diagram showing an example of vendor information used in the embodiment.

As shown in FIG. 2, in the embodiment, a construction contractor selection system 100 includes a construction contractor selection device 10, a first terminal device 20 used by a person in charge of ordering construction work 21, and a second terminal device 20 used by a construction contractor 31. A terminal device 30 is provided. Also, the first terminal device 20 and the second terminal device 30 are connected to the construction contractor selection device 10 via a network 40 such as the Internet so as to be capable of data communication.

Specific examples of the first terminal device 20 and the second terminal device 30 include smart phones, tablet-type terminal devices, and general-purpose PCs (Personal Computers). In the example of FIG. 2, the first terminal device 20 and the second terminal device 30 are smart phones.

In addition, as shown in FIG. 2, the contractor selection system 100 includes a contractor selection device 10 in the embodiment. The contractor selection device 10 includes the candidate selection unit 11, the transmission unit 12, and the determination unit 13 described above. The construction contractor selection device 10 further includes a construction information reception unit 14 , a calculation unit 15 and an information storage unit 16 in addition to the candidate selection unit 11 , transmission unit 12 and determination unit 13 described above. The contractor selection device 10 is constructed by a computer such as a server, as will be described later.

The construction information reception unit 14 receives construction information transmitted from the first terminal device 20 . In the embodiment, the construction information is input by the person in charge of ordering 21 on the application program executed on the first terminal device 20 . As shown in FIG. 3, the construction information includes, for example, the name of the product to be constructed (product name), location information of the construction site (construction site address), the number of products, desired construction date and time, and other data. .

Upon receiving the construction information, the construction information reception unit 14 assigns a construction number to the received construction information, and sends the construction information to which the data of the construction number is attached to the information storage unit 16 . The information storage unit 16 stores received construction information. As shown in FIG. 3, each piece of construction information is stored in the information storage unit 16 in association with each other.

The information storage unit 16 also stores trader information and map data. The map data is used by the candidate selection unit 11 as described later. As shown in FIG. 4, the vendor information includes, for each vendor, identification number, vendor name, workable area, and address data. In addition, the contractor information further includes weight data set for each construction contractor. The weights are used to select the candidates for the orderer, as will be described later. These data are associated with each other and stored in the information storage unit 16 .

The candidate selection unit 11 first accesses the information storage unit 16 to acquire construction information and contractor information. The candidate selection unit 11 can identify contractors located in areas where construction work can be performed on the basis of the acquired construction information and contractor information, and select candidates from the identified contractors. Specifically, the candidate selection unit 11 selects n contractors whose workable area includes the administrative district of the address of the construction site included in the construction information, among the contractors registered in the contractor information. Note that n is an arbitrary natural number.

The candidate selection unit 11 calculates the distance from the address of the construction site to the base address of the construction contractor based on the construction information and the contractor information for each construction contractor, and selects candidates using the calculated distance. You can also Specifically, the candidate selection unit 11 first acquires the map data from the information storage unit 16, and uses the acquired map data to determine the location of each construction company based on the base address registered in the company information. Search the route to the address of the construction site included in the information. Then, the candidate selection unit 11 calculates the distance of the searched route and selects the top n companies with the shortest calculated distance as candidates. The route search process can be performed using an existing search algorithm using map data.

The candidate selection unit 11 can also obtain the distance from the construction site to the base address of the construction company by using an external service server 50 that provides a map service. The service server 50 is connected to the network 40 and provides map services such as map data provision and route search from a destination to a departure point on the Web. In this case, the candidate selection unit 11 executes a route search on the website of the service server 50 using the address of the construction site as the destination and the address of the construction company's base as the departure point. As a result, the candidate selection unit 11 acquires information such as the route and the distance from the address of the construction company's base to the address of the construction site from the service server 50 . This mode is useful when no map data is stored in the information storage unit 16, when the stored map is old, when the stored map data does not cover the construction site area, and the like.

After selecting candidates according to the workable area or distance, the candidate selection unit 11 can further narrow down the candidates using weights set for each construction company. For example, as described above, after selecting n companies based on the workable area or distance, the candidate selection unit 11 can select the top m companies with the highest weight values as final candidates. can. Note that m is any natural number smaller than n.

The weight may be updated by the calculation unit 15 in order to prevent the same construction company from becoming the ordering company more than once. In the embodiment, the calculating unit 15 decreases the weight of the construction contractor determined as the ordering contractor each time the determining unit 13 determines the ordering contractor, and increases the weight of the construction contractor not determined as the ordering contractor. to update the weight value set for each contractor.

Specifically, the calculation unit 15 calculates the weight set for each construction contractor so that the ratio between the construction contractors for the number of times determined by the ordering contractor converges to the ratio of the initial values of the weights between the construction contractors. can be updated.

For example, it is assumed that the initial values of weights are set to 50, 25, 20, and 5 for four contractors A, B, C, and D, respectively. In this case, the ratio of the initial values of the weights is A:B:C:D=10:5:4:1. Therefore, if the number of times that construction contractors A, B, C, and D have each been determined by the ordering contractor is Xa, Xb, Xc, and Xd, the calculation unit 15 calculates the final The weight values are updated so that Xa:Xb:Xc:Xd=10:5:4:1. Note that the initial value of the weight of each contractor is appropriately set according to the size of the company, the amount of sales, the financial situation, and the like.

In the present embodiment, the candidate selection unit 11 can also select candidates using all of the workable area, the distance, and the weight. Specifically, the candidate selection unit 11 first identifies a group of construction companies (first group) located in an area where the construction site can be constructed, based on the construction information and the company information.

Next, for each construction contractor belonging to the first group, the candidate selection unit 11 searches for a route from the construction site address to the base address of the construction contractor using, for example, map data. Calculate the distance. Furthermore, the candidate selection unit 11 selects the first candidate from among the contractors belonging to the first group in order of shortest distance, for example, using the calculated distance.

Next, the candidate selection unit 11 further selects a second candidate based on the weight set for each contractor from among the contractors belonging to the first identified group, excluding the first candidate. elect. In this case, the candidate selection unit 11 selects a first candidate selected based on the workable area and distance and a second candidate selected based on the workable area and weight as candidates.

Further, the candidate selection unit 11 may further narrow down the first candidates by using the weight after selecting the first candidates from among the contractors belonging to the first group. Specifically, the candidate selection unit 11 selects n companies as first candidates from the first group, and selects top m companies with high weight values as final candidates.

When a candidate is selected by the candidate selection unit 11, the transmission unit 12 transmits construction information to the second terminal device 30 of the selected candidate. As a result, the candidate second terminal device 30 displays the contents of the transmitted construction information on the screen. Then, the candidate person-in-charge inputs, on the application program executed on the second terminal device 30, that they will receive the order for the construction work or that they will not receive the order for the construction work. After that, the second terminal device 30 creates data indicating the input result, and transmits the created data to the construction contractor selection device 10 as response data to the construction information.

When response data to the construction information is transmitted from the second terminal device 30, the construction contractor selection device 10 receives the response data. The time from when the response data is transmitted by the second terminal device 30 to when it is received by the contractor selection device 10 varies depending on the performance of the second terminal device 30 and the network conditions. For this reason, in the construction contractor selection device 10, the response data transmitted first may be received later than the response data transmitted later. is received, the response data is continuously received for the set time.

In the embodiment, the determination unit 13 extracts the transmission date and time from the header of the received response data, and specifies the response data with the earliest extracted transmission date and time. The determination unit 13 determines the candidate who transmitted the earliest response data as the candidate who first responded that the order will be accepted as the orderer. Further, when determining the orderer, the determination unit 13 transmits the vendor information to the first terminal device 20 of the person in charge of placing an order for construction work 21 . Further, the determination unit 13 notifies the second terminal device 30 of the construction company 31 determined as the orderer by e-mail or the like that the orderer has been determined. In addition, the determination unit 13 notifies the calculation unit 15 of the contractor determined as the orderer. Thereby, the calculator 15 updates the weight as described above.

[System operation]
Next, the operation of the contractor selection system 100 according to the embodiment will be described with reference to FIG. 5, focusing on the operation of the contractor selection device 10. FIG. FIG. 5 is a flowchart showing the operation of the contractor selection device 10 that constitutes the contractor selection system in the embodiment of the present disclosure. 1 to 4 will be referred to as needed in the following description. Further, in the embodiment, the construction contractor selection method is implemented by operating the construction contractor selection system 100 . Therefore, the description of the construction contractor selection method in the embodiment is replaced with the description of the operation of the construction contractor selection system 100 below.

First, as a premise, the person in charge of placing an order for construction works 21 inputs construction information to the first terminal device 20 . As a result, the first terminal device 20 transmits the input construction information to the construction contractor selection device 10 via the network 40 . As a result, the construction contractor selection device 10 receives the construction information, and the reception of the construction information serves as a trigger to execute each step shown in FIG. 5 below.

As shown in FIG. 5, the construction information reception unit 14 of the construction contractor selection device 10 receives construction information transmitted from the first terminal device 20 (step A1).

In step A<b>1 , the construction information reception unit 14 assigns a construction number to the received construction information, and sends the construction information to which the construction number has been assigned to the information storage unit 16 . As shown in FIG. 3, the information storage unit 16 stores construction information assigned construction numbers.

Next, the candidate selection unit 11 accesses the information storage unit 16, acquires the contractor information and the construction information of the first construction, and based on this information, determines that the construction site is in a workable area. A group of contractors is specified (step A2).

Next, the candidate selection unit 11 calculates the distance from the address of the construction site to the base address of the construction company on the map data for each construction company based on the construction information and the company information (step A3). ). Then, the candidate selection unit 11 selects the first candidate from the group of contractors identified in step A2 using the distance calculated in step A3 (step A4).

Next, based on the weight set for each construction contractor, the candidate selection unit 11 selects construction contractors belonging to the group identified in step A2, excluding the first candidate (although not selected in step A4, , the contractor specified in step A2), a second candidate is further selected (step A5).

Next, the transmitting unit 12 transmits the construction information to the first candidate second terminal device 30 calculated in step A4 and the second candidate second terminal device 30 selected in step A5 ( Step A6). After execution of step A6, when response data to the construction information is transmitted from the second terminal device 30, the construction contractor selection device 10 receives this.

Next, when the response data is received from the second terminal device 30 to which the construction information was transmitted in step A6, the determination unit 13 determines the candidate who transmitted the response data to the effect that the order will be received first as the orderer ( Step A7).

Next, the determination unit 13 contacts the first terminal device 20 of the person in charge of placing an order for construction work 21 and the second terminal device 30 of the construction company 31 determined as the ordering company (step A8). Specifically, the determination unit 13 transmits the contractor information of the orderer to the first terminal device 20 of the person in charge of placing an order for construction work 21, and to the second terminal device 30 of the construction contractor 31 determined as the orderer, Send an e-mail to the ordering company to the effect that it has been decided. Furthermore, the determination unit 13 notifies the calculation unit 15 of the contractor determined as the ordering contractor.

Next, when step A8 is executed, the calculation unit 15 decreases the weight of the contractor determined to be the ordering contractor, increases the weight of the construction contractor not determined to be the ordering contractor, and The set weight value is updated (step A9). After execution of step A9, the processing in the contractor selection device 10 ends.

As described above, when steps A1 to A9 are executed, the orderer is automatically determined for the construction input by the person in charge of ordering 21, without requiring any work by the person in charge of ordering 21. FIG.
