<System configuration>
FIG. 1 is a diagram showing an outline of a configuration example of an information processing system including a construction cost management system according to an embodiment of the present invention. The construction cost management system 100 of the present embodiment is a system capable of allocating construction costs for construction over a plurality of years on an annual basis.

The construction cost management system 100 and the construction design document management device 200 can transmit and receive information to and from each other via the network 300.

The construction design document management device 200 connected to the construction cost management system 100 via the network 300 is a device for storing the construction design document. The construction design document management device 200 creates a new construction design document newly created for each construction type in response to an input operation by the user of the construction design document management device 200, and stores the construction design document. The construction design document includes the total construction cost and at least the construction cost for each year. In addition, the construction design document may include the total construction cost for each subject and the construction cost for each year for each subject.

The construction cost management system 100 and the construction design document management device 200 are implemented by predetermined hardware and software. For example, the construction cost management system 100 and the construction design document management device 200 have a processor, a memory, and the like. A program in memory executed by the processor causes the computers of the construction cost management system 100 and the construction design document management device 200 to function. Further, the construction cost management system 100 and the construction design document management device 200 have input means (keyboard, mouse, etc.) and output means (display means such as display).

The construction cost management system 100 of the present embodiment is, for example, a consumption tax change information acquisition implemented as a software program running on middleware such as an OS (Operating System), a DBMS (DataBase Management System), and a Web server program (not shown). Each unit includes a unit 101, a construction design document acquisition unit 102, a difference calculation unit 103, an input information output unit 104, a determination unit 105, and a determination result output unit 106.

The consumption tax change information acquisition unit 101 has a function of acquiring change information regarding the change of consumption tax. The consumption tax change information acquisition unit 101 acquires the change information by, for example, an input operation by the user of the construction cost management system 100. This change information includes at least the time when the consumption tax is changed and the information indicating the degree of change (for example, 2% increase). When the consumption tax change information acquisition unit 101 acquires the change information, it notifies the construction design document acquisition unit 102 of the acquisition. Further, the consumption tax change information acquisition unit 101 sends the change information to the difference calculation unit 103.

The construction design document acquisition unit 102 has a function of acquiring a construction design document from the construction design document management device 200. Upon receiving the fact that the change information has been acquired from the consumption tax change information acquisition unit 101, the construction design document acquisition unit 102 acquires the construction design document from the construction design document management device 200 via the network 300. The construction design document acquisition unit 102 acquires only the construction design document including the construction cost after the time when the consumption tax is changed. When the construction design document acquisition unit 102 acquires the construction design document from the construction design document management device 200, the construction design document acquisition unit 102 sends the acquired construction design document to the difference calculation unit 103.

The difference calculation unit 103 has a function of calculating the consumption tax difference based on the construction cost allocated to each year and the change information acquired by the consumption tax change information acquisition unit 101. The difference calculation unit 103 acquires change information from the consumption tax change information acquisition unit 101. Further, the difference calculation unit 103 acquires the construction design document from the construction design document acquisition unit 102. The difference calculation unit 103 refers to the acquired construction design document and extracts the construction cost allocated to each year.

The difference calculation unit 103 calculates the total of the construction costs allocated to each year after the time when the consumption tax is changed, and multiplies the total by the degree of change included in the change information. Calculated as the consumption tax difference. The difference calculation unit 103 sends the calculated consumption tax difference and the construction design document to the input information output unit 104.

The input information output unit 104 has a function of outputting a worksheet (input information) including a consumption tax difference calculated by the difference calculation unit 103 and an area for inputting a value for allocating the consumption tax difference to each year. When the input information output unit 104 acquires the consumption tax difference amount and the construction design document from the difference calculation unit 103, the input information output unit 104 generates a worksheet using these information.

Specifically, the input information output unit 104 acquires the total amount of the construction cost described in the construction design document and the construction cost for each year. Further, the input information output unit 104 acquires the construction cost for each subject and the construction cost for each year for each subject from the construction design document. The input information output unit 104 inputs the acquired total amount, the construction cost for each year, the construction cost for each subject, the construction cost for each year for each subject, and the consumption tax difference, and the consumption tax for each year. Generate a worksheet in which the difference, the consumption tax difference of each subject, and the consumption tax difference of each subject for each year are blank. The input information output unit 104 causes the display means to display (output) the generated worksheet.

Here, an example of a worksheet output by the input information output unit 104 will be described with reference to FIG. FIG. 2 is a diagram showing an outline of an example of initial display of a worksheet according to an embodiment of the present invention. As a premise, the construction period is 3 years, the consumption tax will be revised from the 2nd year, and there will be a processing plant fee and a pumping station fee as subjects. The total amount for each subject is the total amount for each subject. "6,300,000" is entered as the total amount of the design amount (construction cost) of the total amount for each subject. In addition, "1,000,000", "2,800,000", and "2,500,000" are entered as the design amounts for the first, second, and third years. In addition, "40,000" is entered as the total amount of the consumption tax difference.

"3,500,000" is entered as the total amount of the design amount of the treatment plant cost. In addition, "1,000,000", "1,000,000", and "1,500,000" are entered as the design amounts for the first, second, and third years. "2,800,000" is entered as the total amount of the design amount of the pumping station cost. Further, "0", "1,800,000", and "1,000,000" are input as the design amounts for the first year, the second year, and the third year, respectively.

In addition, the input areas for the total amount of each subject, the processing plant cost, and the consumption tax difference for the first, second, and third years of the pumping station cost are blank and can be entered. .. In addition, the initial value may be set based on the consumption tax difference in the input area of the consumption tax difference in the first year, the second year, and the third year of the total amount for each subject, the processing plant cost, and the pumping station cost. For example, the consumption tax difference may be set as the initial value in the year in which the consumption tax is modified (the second year in the above example).

Further, the design amount for the first year, the second year, and the third year may be editable. Further, the design amount for the first year, the second year, and the third year may not be entered at the time of initial display.

Returning to the description of FIG. The determination unit 105 determines whether or not the input value is appropriate based on the value input in the input information area output by the input information output unit 104 and the consumption tax difference calculated by the difference calculation unit 103. Is the part to judge.

The worksheet shown in FIG. 2 has means (for example, an “input complete” button) for indicating input completion (for example, not shown). The determination unit 105 detects that the input is completed by the means after the user inputs the consumption tax difference amount and edits the design amount.

When the determination unit 105 detects that the input is completed, it determines whether or not the total amount of the design amount in the first to third years of the total amount for each subject matches the total amount of the design amount. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate.

Further, the determination unit 105 determines whether or not the total of the design amount in the first to third years of the treatment plant cost matches the total amount of the design amount. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate. The determination unit 105 compares the total of the design amount for the first to third years in the pumping station cost with the total amount of the design amount, and determines whether or not they match. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate.

In this way, the determination unit 105 matches the total amount of the design amount for each item of the total amount for each subject, the processing plant cost, and the pump cost with the total of the first to third years of each design amount. If they do not match, it is determined that the entered value is not appropriate.

Subsequently, the determination unit 105 determines whether or not the total of the consumption tax difference in the total amount for each subject in the first to third years matches the total amount of the consumption tax difference. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate.

In addition, the determination unit 105 determines whether or not the total of the consumption tax difference in the processing plant costs in the first to third years matches the total amount of the consumption tax difference. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate. The determination unit 105 compares the total of the consumption tax difference in the pumping station costs from the first year to the third year with the total amount of the consumption tax difference, and determines whether or not they match. If the result of the determination does not match, the determination unit 105 determines that the input value is not appropriate.

In this way, the determination unit 105 determines the total amount of the consumption tax difference for each item of the total amount for each subject, the processing plant cost, and the pump cost, and the total amount of the consumption tax difference for the first to third years. It is determined whether or not they match, and if they do not match, it is determined that the entered value is not appropriate.

In addition, the determination unit 105 matches the total amount of the design amount in each of the above items with the total of the design amounts in the first to third years, and the total amount of the consumption tax difference in each of the above items and the consumption tax. If the difference matches the sum of the first to third years, it is determined that the entered value is appropriate. Here, FIG. 3 shows an example of a worksheet when the determination unit 105 determines that the input value is appropriate. FIG. 3 is a diagram showing an outline of an example of a worksheet in which an amount of money is appropriately input according to an embodiment of the present invention.

As shown in FIG. 3, the total amount of the design amount in each of the above items and the total amount of the design amount in the first to third years are the same. For example, the total amount of the design amount for each subject is "6,300,000", and the total amount of the design amount for each subject in the first to third years is "6,300,000". In addition, the total amount of the consumption tax difference of the total amount for each subject is "40,000", and the total amount of the consumption tax difference of the total amount for each subject in the first to third years is "40,000".

When the determination unit 105 determines that the input value is not appropriate, the determination unit 105 sends a notification to that effect to the determination result output unit 106. Further, when the determination unit 105 determines that the input value is appropriate, the determination unit 105 transmits the determination result output unit 106 to that effect and also transmits the acquired construction design document.

The determination result output unit 106 has a function of outputting a result based on the determination by the determination unit 105. When the determination result output unit 106 receives from the determination unit 105 that the input value is not appropriate, the determination result output unit 106 outputs an error message on the worksheet. As a result, the user can be prompted to correct the input.

Further, the determination result output unit 106 acquires the value input on the worksheet when the input value is appropriate and receives the construction design document from the determination unit 105, and determines the value for the construction design. Reflect in the book. Specifically, the determination result output unit 106 reflects the total amount of the design amount and the consumption tax difference in each of the above items input to the worksheet in the construction design document for the first to third years. Then, the determination result output unit 106 transmits the reflected construction design document to the construction design document management device 200 via the network 300, and requests the update of the construction design document. The construction design document management device 200 updates the construction design document in response to the update request.

The construction cost management system 100 shown in the example of FIG. 1 may be configured by distributing the functions to a plurality of server systems or the like, or may be configured by consolidating the functions into one server system. Further, the construction cost management system 100 and the construction design document management device 200 may be integrated into one server system.

<Processing flow (change in construction cost due to change in consumption tax)>
FIG. 4 is a diagram showing an outline of an example of a processing flow for changing the construction cost due to the change in consumption tax in the present embodiment. First, the consumption tax change information acquisition unit 101 acquires the change information by an input operation or the like by the user of the construction cost management system 100 (S1).

Subsequently, the construction design document acquisition unit 102 acquires the construction design document from the construction design document management device 200 (S2). The difference calculation unit 103 refers to the acquired construction design document and extracts the construction cost allocated to each year. In addition, the difference calculation unit 103 calculates the total of the construction costs allocated to each year after the time when the consumption tax is changed, and multiplies the total by the degree of change as the consumption tax difference. Calculate the value (S3). The input information output unit 104 acquires the consumption tax difference amount and the construction design document from the difference calculation unit 103, generates a worksheet using the information, and outputs the worksheet (S4). Subsequently, the determination unit 105 determines whether or not the input is completed (S5). If the determination unit 105 does not detect that the input is completed (S5: No), the determination unit 105 proceeds to step S5 again and waits until it detects that the input is completed.

When the determination unit 105 detects that the input is completed (S5: Yes), the total amount of the design amount for each item of the total amount for each subject, the processing plant cost, and the pump cost, and the amount for the first to third years. Determine if they match the sum of. That is, the determination unit 105 determines whether or not the total design amount for each year is appropriate (S6). When the total design amount for each year is not appropriate (S6: No), the determination unit 105 sends a message to that effect to the determination result output unit 106. The determination result output unit 106 outputs an error message in response to this (S7), and proceeds to step S5.

When the total design amount for each year is appropriate (S6: Yes), the judgment unit 105 determines the total amount of the consumption tax difference for each item of the total amount for each subject, the processing plant cost, and the pump cost, and 1 for each. It is determined whether or not the total consumption tax difference between the years to the third year matches. That is, the determination unit 105 determines whether or not the total consumption tax difference for each year is appropriate (S8). If the total consumption tax difference for each year is not appropriate (S8: No), the determination unit 105 proceeds to step S7.

Further, when the judgment unit 105 determines that the total consumption tax difference for each year is appropriate (S8: Yes), the judgment result output unit 106 acquires the value input on the worksheet and constructs the value. Reflect in the design document (S9).

As described above, the construction cost management system 100, which is an embodiment of the present invention, calculates the consumption tax difference based on the change information and the design amount allocated to each year. Further, the construction cost management system 100 outputs a worksheet including the consumption tax difference and the input area for allocating the consumption tax difference to each year. The construction cost management system 100 determines whether or not the value input in the input area and the value input based on the consumption tax difference are appropriate, and if not, outputs an error message and is appropriate. If so, reflect the entered value in the construction design document.

In this way, the construction cost management system 100 determines whether or not the value entered in advance is appropriate when the consumption tax difference is assigned to each year, so that the consumption tax can be modified in the middle of the period of a plurality of years. If it does occur, the allocation of the consumption tax difference can be set appropriately. For example, if it is determined that the input value is not appropriate, the construction cost management system 100 outputs an error message, so that it is possible to prevent miscalculation due to an input error by the user. If the input value is appropriate, the construction cost management system 100 reflects the input value in the construction design document. As a result, the user does not need to recreate the construction design document separately, and the man-hours of the user can be reduced.

Further, in the construction cost management system 100, an initial value may be set in the input area of the consumption tax difference based on the consumption tax difference. In this case, it is possible to output the worksheet with the consumption tax difference assigned as the initial value, and if the input is completed as it is, the consumption tax difference can be set appropriately without setting the value by the user. Can be done.

In the above-described embodiment, the case where the design amount of the first year, the second year, and the third year can be edited has been described, but the design amount may not be editable. In this case, it is not necessary to determine whether or not the total of the design amounts in the first year, the second year, and the third year is appropriate.

In the above-described embodiment, the case where the design amount for the first year, the second year, and the third year is initially displayed has been described, but the design amount for the first to third years may not be initially displayed. In this case, after the design amount for the first to third years is input, the difference calculation unit 103 determines the consumption tax difference based on the input design amount for the first to third years and the change information. Will be calculated.
