[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0024] [1. Overview] First, an overview of the present invention will be described.

[0025] In the construction industry, rentals are recorded when construction equipment is used. Here, rentals are expenses calculated by converting the total life cycle cost, including depreciation, maintenance and repair costs, and / or management costs, into a daily amount. For example, if equipment with a rental cost of 30,000 yen is used for three days on work A and two days on work B, the rental for work A will be 90,000 yen (= 30,000 yen * 3 days), and the rental for work B will be 60,000 yen (= 30,000 yen * 2 days).

[0026] Previously, data on incoming and outgoing equipment, such as which equipment was used for which construction project, was managed, but calculating rental fees from the number of days and inputting the expense entries from the calculation results was done separately, which was inefficient. Also, previously, the calculation of rental fees and input of the entries were often done together at the end of the month, making it impossible to grasp the amount of costs incurred on a daily basis.

[0027] Therefore, in this embodiment, a mechanism is provided that enables daily calculation of expenses, thereby enabling timely understanding of cost occurrence.

[0047] [3. Specific Examples] A specific example of this embodiment will be described with reference to FIGS.

[0048] [Rental management processing] Here, an example of rental management processing in this embodiment will be described with reference to Fig. 4 to Fig. 8. Fig. 4 is a flowchart showing an example of processing of the rental management device 100 in this embodiment.

[0049] As shown in FIG. 4, when a user inputs data on the transport of equipment at a construction site during a construction period via the input device 112, the equipment receipt and payment acquisition unit 102a acquires the equipment receipt and payment data based on the transport data, and stores the equipment receipt and payment data in the accounting file 106c (step SA-1).

[0050] Then, based on the equipment master 106a, the calendar master 106b, and the equipment receipt and payment data, the equipment rental acquisition unit 102b acquires the rental value for the equipment by multiplying the number of days from the equipment's delivery date or the start of the construction period of the current term to the equipment's removal date or the date subject to rental calculation by the rental cost per day for the equipment, acquires equipment rental data including the rental value, and stores the equipment rental data in the accounting file 106c (step SA-2).

[0051] Then, the cost creating unit 102c creates cost data including the rental cost for each construction project in the current term based on the equipment rental cost data, and stores the cost data in the journal file 106c (step SA-3).

[0052] Then, the updating unit 102d determines whether the end of the term has arrived (step SA-4).

[0053] If the updating unit 102d determines that the end of the term has not yet arrived (step SA-4: No), it waits until carry-in / out data is input via the input device 112, and then shifts the process to step SA-1.

[0054] On the other hand, if the updating unit 102d determines that the end of the term has arrived (step SA-4: Yes), it shifts the process to step SA-5.

[0055] Then, the updating unit 102d judges whether or not a construction suspension period occurred during the construction period of the current term (step SA-5).

[0056] Then, when it is determined that no construction suspension period has occurred during the construction period of the current term (step SA-5: No), the updating unit 102d shifts the process to step SA-9.

[0057] On the other hand, if the updating unit 102d determines that a construction suspension period occurred during the construction period of the current term (step SA-5: Yes), it shifts the process to step SA-6.

[0058] Then, the update unit 102d updates the calendar master 106b so that the rental calculation dates corresponding to the construction suspension period that occurred during the current construction period are excluded from the rental calculation, and updates the equipment receipt and payment data based on the updated calendar master 106b to add adjustment days corresponding to the construction suspension period and / or adjustment hours corresponding to the construction suspension period (step SA-6).

[0059] Then, based on the equipment master 106a, the calendar master 106b updated by the update unit 102d, and the equipment receipt and payment data updated by the update unit 102d, the equipment rental acquisition unit 102b acquires the rental value for the equipment by multiplying the number of days from the equipment delivery date or the start of the construction period of the current term to the equipment removal date or the date subject to rental calculation by the rental cost per day for the equipment, acquires equipment rental data including the rental value, and stores the equipment rental data in the journal file 106c (step SA-7).

[0060] Then, the cost creating unit 102c creates cost data including the rental cost for each construction work in the current term based on the equipment rental cost data, and stores the cost data in the journal file 106c (step SA-8).

[0061] Then, the journal entry creation unit 102e creates expense entry data for each construction project for the current period, based on the cost data, with the debit account item being "uncompleted construction expenditure" and the credit account item being "indirect machinery rental expenses" (step SA-9), and ends the processing.

[0062] Here, a specific example of the rental management process in this embodiment will be described with reference to Figures 2, 3, and 5 to 8. Figures 5 to 8 are flow charts showing an example of the rental management process in this embodiment.

[0063] 5, in this embodiment, on December 1, 2018, K001: crane and K002: boring machine are shipped from the equipment center to construction A, and the user inputs the shipping data to obtain equipment receipt and payment data (step SB-1). At this time, the equipment has not yet arrived at the construction site, so no rental fee is incurred.

[0064] Then, as shown in FIG. 5, in this embodiment, on December 3, 2018, K001: crane and K002: boring machine arrive at the site of construction A and begin to be used, equipment receipt and payment data is obtained by the user entering inventory data, and equipment rental data and cost data are obtained based on the equipment master 106a, calendar master 106b, and the equipment receipt and payment data (step SB-2).

[0065] 6, in this embodiment, on December 6, 2018, K001: a crane is sent from the site of work A to the site of work B, the user inputs the sending data to obtain equipment receipt and payment data, and equipment rental data and cost data are obtained based on the equipment master 106a, calendar master 106b, and the equipment receipt and payment data (step SB-3). Thus, in this embodiment, the sending date is not counted as a day for rental calculation.

[0066] Then, as shown in FIG. 6, in this embodiment, on December 8, 2018, K001: crane arrives at the site of construction B and begins to be used, equipment receipt and payment data is obtained by the user entering inventory data, and equipment rental data and cost data are obtained based on the equipment master 106a, calendar master 106b, and the equipment receipt and payment data (step SB-4).

[0067] Then, as shown in FIG. 7, in this embodiment, on December 12, 2018, K001: the crane is returned from the site of construction B to the equipment center, and K002: the boring machine is returned from the site of construction A to the equipment center, and equipment receipt and payment data is obtained by the user inputting the shipping data, and equipment rental data and cost data are obtained based on the equipment master 106a, calendar master 106b, and the equipment receipt and payment data (step SB-5).

[0068] Then, as shown in FIG. 7, in this embodiment, on December 15, 2018, K001: crane and K002: boring machine arrive at the equipment center and are stored in stock, and equipment receipt and payment data is obtained by the user entering the storage data, and equipment rental data and cost data are obtained based on the equipment master 106a, calendar master 106b, and the equipment receipt and payment data (step SB-6).

[0069] Then, as shown in Fig. 8, in this embodiment, in December 2018, the equipment was at the construction site, but in order to adjust the period during which construction was stopped due to factors such as natural disasters (e.g., typhoons) from the number of days of use, two days of construction A (December 9, 2018 to December 10, 2018) are excluded from the rental calculation by inputting a rental adjustment by the user (step SB-7). Thus, in this embodiment, as shown in Fig. 3, by setting December 9, 2018 to December 10, 2018 as excluded from the rental calculation in the calendar master 106b, the period is not counted as a number of days subject to rental calculation.

[0070] Then, as shown in Figure 8, in this embodiment, expense accounting data for construction work A and construction work B for December 2018 is created (step SB-8), where the debit account item is "uncompleted construction expenditure" and the credit account item is "indirect machinery rental expense" at the end of December 2018.
