[0037] The supplier 3 is a database DB that sells fuel to each business (primary contractor and subcontractors) at the construction site and manages the sold fuel. A tablet terminal, a personal computer, etc. can be used as the supplier 3. The supplier 3 is configured to store a fuel management application program for management purposes and has the function of sending the amount of fuel used that has been sold to the information processing device 10. The supplier 3 may be configured such that the database DB is connected to a computer or various terminals, or a memory unit built into the computer or various terminals can be constructed as the database DB.

[0038] The user terminal 2 and the supplier 3 (supplier terminal) may be configured not to have their respective fuel management application programs. In this case, the user terminal 2 and the supplier 3 can view and transmit each piece of information using a web browser or the like (or acquisition processing from the information processing device 10).

[0039] <Hardware configuration> 2(a) is a diagram showing an example of the hardware configuration of the information processing device 10. The information processing device 10 includes a control unit 11, a storage unit 12, and a communication unit 13 as the hardware configuration.

[0040] The control unit 11 includes one or more processors such as a CPU, and controls the overall operation and processing of the information processing device 10 by executing the fuel management program according to the present invention, an OS, and other applications.

[0041] The storage unit 12 is an HDD, SSD, ROM, RAM, etc., and stores the fuel management program according to the present invention and data used when the control unit 11 executes processing based on the program. The control unit 11 executes processing based on the fuel management program stored in the storage unit 12, thereby realizing the functional configuration described below.

[0042] The communication unit 13 controls communication with the network NW, and performs inputs required to operate the information processing device 10 and outputs related to the operation results.

[0043] 2(b) is a diagram showing an example of the hardware configuration of a terminal 90 (user terminal 2 in FIG. 1). The terminal 90 includes, as its hardware configuration, a control unit 91, a storage unit 92, a communication unit 93, an input unit 94, and an output unit 95.

[0044] The control unit 91 of the terminal 90 includes one or more processors such as a CPU, and controls the overall operation and processing of the terminal 90. The storage unit 92 of the terminal 90 is an HDD, SSD, ROM, RAM, or the like, and stores the above-mentioned fuel management application program as well as data and the like used when the control unit 91 executes processing based on the program.

[0045] A communication unit 93 of the terminal 90 controls communication with the network. An input unit 94 of the terminal 90 is a touch panel, a mouse, a keyboard, or the like, and inputs operation requests from the user to the control unit 91. An output unit 95 of the terminal 90 is a display, or the like, and displays the results of processing by the control unit 91, etc.

[0046] <Functional configuration> 2(a), the information processing device 10 includes, as its functional configuration, an acquisition unit 101, an identification information issuing unit 102, a specification unit 103, a calculation unit 104, and a display processing unit 105. These are information processing performed by software (stored in the storage unit 12) that is specifically realized by hardware (such as the control unit 11).

[0047] The acquisition unit 101 acquires (receives) various types of information from the user terminal 2, the fuel supplier 3, etc. In this embodiment, the acquisition unit 101 acquires fuel information for each type of fuel ordered and / or delivered from the supplier 3 in association with identification information (a unique code, described later). Specifically, the acquisition unit 101 acquires, from the supplier 3, the identification information and fuel information included in the order and / or delivery from the user terminal 2 to the supplier 3.

[0048] The identification information issuing unit 102 issues identification information. In this embodiment, the identification information issuing unit 102 creates identification information using the construction system, and issues (transmits) the identification information to the supplier 3 and the user terminal 2.

[0049] The identification unit 103 identifies fuel consumption and the like based on predetermined conditions. In this embodiment, the identification unit 103 identifies fuel consumption for each construction site of the prime contractor based on the identification information and fuel information stored in the memory unit 12. Furthermore, the identification unit 103 identifies fuel consumption for each supplier at a specific construction site of the prime contractor based on the identification information, fuel information, and supplier information.

[0050] For example, the identification unit 103 can identify fuel consumption corresponding to each fuel type for each supplier at a specific construction site of a prime contractor based on the identification information, fuel information, and supplier information. Furthermore, the identification unit 103 identifies fuel information ordered and / or delivered from a subcontractor as fuel consumption of a prime contractor that has a subordinate relationship with the subcontractor based on the construction system. The identification unit 103 may also identify fuel information ordered and / or delivered from a subcontractor as fuel consumption of a subcontractor related to the prime contractor based on the construction system. The identification unit 103 can identify fuel consumption of a prime contractor and / or a construction site based on input of predetermined conditions from the user terminal 2.

[0051] The calculation unit 104 calculates various information based on predetermined conditions. In this embodiment, the calculation unit 104 calculates fuel consumption for a predetermined period using all or any of the identification information, fuel information, contractor information, construction site information, and construction system. For example, the calculation unit 104 can calculate fuel consumption for a predetermined period using the identification information and fuel information.

[0052] The calculation unit 104 can also calculate the CO2 emissions for each construction site of the prime contractor based on the identification information, fuel consumption, and conversion information. The calculation unit 104 can also calculate the CO2 emissions under predetermined conditions based on the fuel consumption and conversion information identified by the identification unit 103.

[0053] The display processing unit 105 processes and displays various information on the user terminal 2, etc. In this embodiment, the display processing unit 105 processes and displays fuel consumption for a predetermined period based on identification information (unique code) and fuel information, and transmits the results of the display processing. The display processing unit 105 also processes and displays CO2 emissions for a predetermined period based on the identification information, fuel information, and conversion information, and transmits the results of the display processing.

[0054] Furthermore, the display processing unit 105 can display the fuel consumption and CO2 emissions for a predetermined period for each prime contractor (user) based on input from the prime contractor. The display processing unit 105 can display the fuel consumption and CO2 emissions for a predetermined period for each construction site based on input from the prime contractor (user). The display processing unit 105 displays the fuel consumption identified by the identification unit 103 and transmits the results of the display processing. The display processing unit 105 can display the CO2 emissions calculated by the calculation unit 104 and transmit the results of the display processing to a user terminal or the like.

[0055] <Database> 1 stores various information necessary for fuel management at a construction site, such as contractor information, construction site information, construction organization information, identification information (unique code) for identifying the construction site and the prime contractor, conversion information for converting various fuels used at the construction site into CO2 emissions, fuel information on fuels used at the construction site, CO2 emissions information (CO2 emissions) corresponding to fuel consumption at the construction site, and other information. Some or all of these may be stored in the memory unit 12 or the like, or some of these may be stored in a separate database or the like.

[0056] The fuel management system 1 and the processing contents of each functional component will be described below with reference to FIGS.

[0057] <Outline of fuel management system> The fuel management system 1 of this embodiment is a system for easily and accurately visualizing and centrally managing fuel consumption and CO2 emissions according to user requests at construction sites where multiple types of fuel are traded by various fuel suppliers to various construction companies with complex subordinate relationships.

[0058] A schematic image of a fuel management system according to one embodiment of the present invention is shown in Figure 3. As shown in the figure, when a prime contractor or a subcontractor purchases fuel at a construction site (execution site), they communicate (share) with the fuel supplier the type and quantity of fuel they wish to purchase, along with a unique code (details will be described later) ((1) in Figure 3).

[0059] The unique code is issued in advance and shared among various suppliers, such as the prime contractor and fuel supplier. For example, if there are multiple fuel suppliers (Company A and Company B in Figure 3), the same unique code will be transmitted to both Company A and Company B when purchasing fuel. The fuel supplier manages the ordered fuel along with the unique code. The ordered fuel associated with the unique code is then delivered to the construction site C ((2) in Figure 3). The prime contractor can also transmit the unique code to the fuel supplier when the fuel is delivered, rather than transmitting the unique code when ordering fuel, or both when the fuel is ordered and when it is delivered. In the following, in this embodiment, the flow of transmitting the unique code when ordering fuel will be mainly explained.

[0060] The fuel management system 1 acquires fuel information ordered by multiple prime contractors and subcontractors at each construction site from fuel suppliers (Company A and Company B), centrally manages the fuel information (fuel data) using a unique code as a key ((3) in Figure 3), and can identify and display fuel consumption under specified conditions based on requests from prime contractor D and prime contractor E. The processing flow in the fuel management system 1 according to this embodiment will be described in detail below.

[0061] <Registering various information> 4 shows a flowchart of the processing procedure in the fuel management system 1 according to one embodiment of the present invention. In S201, a user such as a prime contractor registers various pieces of information necessary for fuel management. The acquisition unit 101 of the information processing device 10 acquires various pieces of information used for fuel management and registers them in the storage unit 12.

[0062] As shown in Figure 5(a), contractor information includes information such as contractor name, contractor contact information, contractor address, type of subordination (primary contractor, subcontractor, etc.), and contractor code for identifying the primary contractor to which the contractor is subordinate, and is managed using a contractor ID. The contractor code can also be managed as information (table) separate from the contractor information, in the form of a table showing the correspondence between the contractor code and the primary contractor. Also, as shown in Figure 5(b), construction site information includes information such as the site name, project name, site address, construction period, and site code for identifying the construction site, and is managed using a construction site ID.

[0063] Furthermore, as shown in Figure 5(c), the construction organization information is managed by the construction organization ID, including information such as the construction site ID, contractor ID, subordinate relationships between contractors at the construction site, contractor ID indicating the parent contractor (subordinate prime contractor, parent company), job duties such as site supervisor and civil engineer, etc. For example, if your company is the prime contractor in Figure 5(c), you can enter your company's contractor ID as the parent contractor's contractor ID.

[0064] A schematic image of a construction system according to one embodiment of the present invention is shown in Figure 6. As shown in the figure, the construction system shows the subordinate relationships between a prime contractor and multiple subcontractors (contractors).

[0065] The construction system in Figure 6 is diagrammatically expressed so that the subordinate relationships between contractors can be seen at a glance. Figure 6 is expressed as a schematic image for understanding the construction system in this embodiment. The memory unit 12 of the information processing device 10 stores construction system information including information on the construction site, the subordinate relationships between the prime contractor and multiple subcontractors, etc. In this specification, the construction system information in Figure 5(C) may also be simply referred to as the construction system.

[0066] In Figure 6, the subcontractors from 1st to 5th tiers for prime contractor A and their subordinate relationships are shown for each job function, such as scaffolding, civil engineering, and interior design. In Figure 6, the subcontractors (subcontract companies) performing the job of "scaffolding" are shown as D Construction (1st tier) and E Construction (2nd tier), and the subcontractors performing "civil engineering" are shown as F Group (1st tier), G Industry (2nd tier), and H Machinery (3rd tier). In addition, the subcontractors performing "interior work" are shown as J Interior (1st tier), K Construction (2nd tier), L House (3rd tier), Yamada Taro (4th tier), Sato Ichiro (5th tier), and Nakamura Jiro (5th tier).

[0067] Furthermore, as shown in Figure 6, the construction system is linked to contractor information, including information on the prime contractor and subcontractors, construction site information related to the construction site, and user information (not shown in Figure 5) indicating the person in charge at the prime contractor, etc. By linking contractor information, construction site information, user registration information, etc. to the construction system in this way, it is possible to easily and accurately manage fuel consumption (fuel purchased or used at the construction site) at a construction site where complex subordinate relationships between subcontractors may occur.

[0068] <Issuance of unique code (identification information)> In S202 of Fig. 4, the identification information issuing unit 102 of the information processing device 10 issues a unique code. The unique code (identification information) is a code for identifying a prime contractor at a specific construction site and for centrally managing fuel consumption. As shown in Fig. 5(d), the unique code is associated with a contractor ID, a site ID, a contractor code, a site code, etc. The unique code as identification information in this embodiment is a code that associates a construction site with a prime contractor.

[0069] This unique code is composed of a combination of a contractor code (four alphabetical characters in Figure 5(a)) and a site code (six numeric digits in Figure 5(b)). Naturally, the number of alphabetical characters, the number of numeric digits, and the character types in the unique code can be determined or changed as appropriate.

[0070] The identification information issuing unit 102 uses the construction system to create a unique code as identification information, and issues this unique code to the supplier 3 and the user terminal 2. By using the unique code in this embodiment, for example, when a prime contractor orders (and / or delivers) fuel at a construction site, the unique code is transmitted (shared) with the supplier 3 along with the type and quantity of fuel. The supplier 3 can manage the order quantities from prime contractors and the like for each fuel type along with the unique code.

[0071] In this way, by issuing a unique code and sharing it with each related contractor, fuel consumption can be managed easily and accurately at construction sites where multiple prime contractors and subcontractors have complex subordinate relationships and where transactions with multiple suppliers 3 involve multiple types of fuel.

[0072] In S203 of Fig. 4, the prime contractor or subcontractor places an order for fuel with Supplier 3 in association with the unique code. As described above, by associating a unique code when ordering fuel, the prime contractor or subcontractor can grasp the combination of the construction site and prime contractor for the fuel order, and this information can be shared among multiple businesses.

[0073] In reality, subcontractors may order fuel at a construction site, and in such cases, the amount of fuel ordered may be managed as the order amount of the prime contractor to which the subcontractor is subordinate. In this embodiment, by using a unique code that identifies the construction site and the prime contractor, the order of the subcontractor can be easily identified as the order of the prime contractor. In addition, in this embodiment, by using the unique code, the order amount can also be managed as the order amount of the subcontractor related to the prime contractor.

[0074] <Identifying fuel consumption over a given period> In S204, the acquisition unit 101 acquires fuel information from the supplier 3. The acquisition unit 101 acquires fuel information for each fuel type ordered in association with identification information from the supplier 3. The fuel information includes a subcontractor (A Construction or F Group) that indicates the fuel orderer.

[0075] For example, the acquisition unit 101 acquires fuel information on the purchase amount for each fuel type from the supplier 3, such as "XX liters of gasoline and XX liters of diesel oil for the prime contractor at a specific construction site, and XX liters of diesel oil for the subcontractor," and stores the information in the memory unit 12. The acquisition unit 101 can also acquire fuel information from multiple suppliers 3 at a specific construction site and store the information in the memory unit 12.

[0076] As shown in Figure 7(a), fuel information is managed by a purchase ID and includes information such as the purchasing company such as A Construction or F Group, a unique code, a contractor code to identify the general contractor, a site code to identify the construction site, the general contractor that is subordinate to the purchasing company, the fuel type such as diesel or gasoline, the amount of fuel purchased, and the purchase date (or purchase date and time) of the fuel.

[0077] In this embodiment, fuel transactions are conducted in association with a unique code, making it possible to accurately grasp which purchaser purchased how much fuel (and fuel type) at which construction site and when.

[0078] In S205, the identification unit 103 identifies fuel consumption under predetermined conditions. The identification unit 103 can identify fuel consumption for each construction site of the prime contractor based on the identification information (unique code) and fuel information stored in the storage unit 12. Details of the display process will be described later, but for example, as shown in Fig. 8, the fuel purchased by purchasing companies (prime contractors and subcontractors) for each prime contractor and construction site can be identified as the purchase amount for each fuel type, and the identification results can be displayed on the user terminal 2 or the like.

[0079] The identification unit 103 can identify fuel consumption based on various conditions using various information stored in the memory unit 12. For example, the identification unit 103 can identify fuel consumption for each construction site of a prime contractor. In this case, the identification unit 103 performs identification processing based on the identification information and fuel information stored in the memory unit 12.

[0080] In addition, the specifying unit 103 specifies the fuel consumption for each supplier at a specific construction site of the prime contractor. Further, the specifying unit 103 specifies the fuel consumption corresponding to each fuel type for each supplier at a specific construction site of the prime contractor. In this case, the specifying unit 103 performs a specifying process based on the identification information, fuel information, and supplier information stored in the storage unit 12.

[0081] As shown in FIG. 5(e), the supplier information includes the supplier's company name, sales area, sales fuel type (not shown), etc., and is managed by a supplier ID. Also, when specifying the fuel consumption for each supplier, information (supplier ID) for grasping the supplier serving as the fuel supply source in advance when acquiring the fuel information is included.

[0082] For example, in this embodiment, the supplier ID is shared with Supplier 3 in advance, and the Supplier 3 can link the supplier ID to the fuel information. In this case, the acquisition unit 101 acquires the fuel information linked with the supplier ID.

[0083] The specifying unit 103 in this embodiment can specify the fuel information ordered from a cooperating contractor as the fuel consumption of the prime contractor having a subordinate relationship with the cooperating contractor based on the construction system, or can specify the fuel information ordered from a cooperating contractor as the fuel consumption of a cooperating contractor related to the prime contractor.

[0084] As described above, the specifying unit 103 in this embodiment can easily and accurately perform a specifying process according to the requirements of the prime contractor (user) by using various information stored in the storage unit 12.

[0085] <Calculation of CO2 Emission> In S206 of FIG. 4, the calculating unit 104 calculates the CO2 emission corresponding to the fuel consumption. The calculating unit 104 calculates the CO2 emission for each construction site of the prime contractor based on the identification information, fuel consumption, and conversion information. The calculating unit 104 can calculate the CO2 emission for a predetermined period based on a predetermined condition.

[0086] 5(f), the conversion information includes the fuel type such as gasoline or diesel, the CO2 conversion coefficient for each fuel type, etc., and is managed by a conversion ID. In this embodiment, accurate CO2 emissions under predetermined conditions can be calculated using the conversion information for each fuel type.

[0087] For example, as shown in Figure 7(b), CO2 emissions are managed by an emissions ID, which includes information such as a purchase ID that manages fuel information, a unique code, a construction system ID, a fuel type, a conversion ID, the amount of fuel purchased, and CO2 emissions. In Figure 7(b), CO2 emissions are calculated for each type of purchased fuel, but the items included in the emissions information are changed as appropriate depending on the calculation conditions, etc. The calculation unit 104 in this embodiment can calculate the CO2 emissions for each fuel consumption under the various conditions identified by the identification unit 103 described above.

[0088] <Display processing> In S207, the display processing unit 105 performs display processing of various information based on predetermined conditions. Fig. 8 shows an example of a display processing result in one embodiment of the present invention. The display processing unit 105 performs display processing of fuel consumption for a predetermined period based on the identification information (unique code) and fuel information, and transmits the result of the display processing. The display processing unit 105 can also perform display processing of the fuel consumption identified by the identification unit 103, and transmit the result of the display processing to the user terminal 2 or the like (such as the prime contractor).

[0089] Figure 8 is an example of fuel consumption for a predetermined period that has been displayed using fuel information and construction systems. As shown in Figure 8, the purchased amount (L) for each fuel type is displayed along with information such as the name of the prime contractor, the name and address of the construction site, the start and completion dates, and the purchasing company. The display processing unit 105 can selectively display the required items using the fuel information (and construction systems, etc.) in Figure 7(a).

[0090] This display process allows users such as prime contractors to easily grasp the exact amount of fuel purchased over a given period. Note that Figure 8 (and Figures 9 to 11, which will be described later) does not correspond to the information in Figures 5 and 7, but is an example that clearly shows the results of the display process.

[0091] Furthermore, in this embodiment, fuel consumption (amount of fuel purchased) can be searched (specified) based on predetermined conditions, and the search results can be displayed, as shown in Fig. 9. A search area W20 showing a screen for searching based on various conditions and a result area W30 showing a screen of the search results are displayed on the display screen W10 in Fig. 9.

[0092] The search area W20 displays the site name of the construction site, the name of the prime contractor, the display method such as monthly display or daily display, the fuel type such as gasoline, diesel, kerosene, and the aggregation period. The display processing unit 105 displays information related to the fuel consumption desired by the prime contractor and the like in the result area W30 based on the identification results (and calculation results) identified (and calculated) using various information stored in the memory unit 12 such as identification information, fuel information, and construction system in response to various selection inputs from the user terminal 2, and transmits the results of the display processing to the user terminal 2.

[0093] In Figure 9, search area W20 has a check box for subordinate relationships. By selecting (checking or touching) this check box, fuel purchased by subcontractors subordinate to the prime contractor is also identified as the purchase amount of the prime contractor. In Figure 9, the prime contractor name is selected (checked), so for example, based on the prime contractor name, X Construction, multiple construction sites (AAA site, BBB site, etc.) for which X Construction is the prime contractor are displayed. In addition, because gasoline, diesel, and kerosene are all selected as fuel types, the total amount of all fuels is identified as the purchase amount.

[0094] For example, if only gasoline is selected as the fuel type, only the amount of gasoline purchased at each construction site is specified, and if only diesel is selected, only the amount of diesel purchased at each construction site is specified, and these figures are displayed for each predetermined period (by month in Figure 9). In this way, in this embodiment, the necessary purchase amounts can be displayed as needed in response to the prime contractor's requests.

[0095] As another search example, in Figure 10, the site name is selected (checked), so by entering a specific site name in search field W20, the fuel purchase amounts for multiple contractors associated with that site name are displayed. In Figure 10, the fuel purchase amounts for each fuel type for XX Construction and △△ Construction at the AAA site are displayed.

[0096] In Figure 10, the subordinate relationship check box is not selected, so the fuel purchase volume purchased only by the prime contractor, such as XX Construction, is identified (fuel purchased by subcontractors is not included), and the identified results are displayed. In this way, this embodiment allows for flexible display response according to the prime contractor's requests, and can display appropriate items and purchase volumes according to search conditions, etc.

[0097] 11, it is also possible to display the amount of CO2 emissions corresponding to the fuel consumption. As with the display process for fuel, the display process for CO2 emissions can also display the amount of CO2 emissions corresponding to the fuel identified by the identification unit 103. The calculation unit 104 calculates the amount of CO2 emissions using the fuel consumption and conversion information identified by the identification unit 103, and the display processing unit 105 displays the amount of CO2 emissions based on the calculation result by the calculation unit 104.

[0098] In Figure 11, the dependency relationship in search area W20 is selected (checked), so the result area W30 displays the combined dependent CO2 emissions, which includes the fuel purchases of subcontractors subordinate to XX Construction at the AAA site, and the CO2 emissions of XX Construction alone (prime contractor only), which does not include the purchases of subcontractors.

[0099] In this way, in this embodiment, it is possible to display side by side the dependent total in which the fuel purchase amount of the subcontractors is included in the fuel purchase amount of the prime contractor, and the fuel purchase amount of the prime contractor only, which does not include the fuel purchase amount of the subcontractors. Note that the search conditions (search items) and display processing in Figures 9 to 11 described above can be flexibly applied to either fuel or CO2 emissions, regardless of whether the target of the display processing is fuel or CO2 emissions (the search function is the same regardless of whether it is fuel or CO2 emissions).

[0100] As described above, the fuel management system 1 according to the present invention can easily and accurately manage fuel and CO2 emissions in transactions involving multiple types of fuel between multiple prime contractors and multiple suppliers at a construction site by executing predetermined processing using identification information (unique codes) and the like.

[0101] Naturally, the same effects as those of the present invention can be obtained from a fuel management method executed by the above-described fuel management system 1 and a fuel management program having the same functions as those of the present fuel management system 1. Furthermore, although fuel management at a construction site has been described in this embodiment, the same effects as those of the present invention can be obtained when the fuel management system 1 is used in fields other than construction sites.
