Description

The present invention relates to an equipment evaluation system, program, and method for evaluating various types of equipment, such as gardening equipment.

When obtaining a loan from a financial institution using real estate such as land or buildings as collateral, the financial institution evaluates the real estate as collateral based on certain criteria. For example, in the evaluation of buildings, the remaining useful life of the building is calculated using the general useful life according to the type of building and the number of years that have passed since construction. The current value of is determined.

Patent No. 6511558

As mentioned above, the remaining useful life (remaining life) of buildings, etc., calculated in the process of collateral evaluation, is simply calculated by subtracting the elapsed years from the expected useful life of the building, regardless of the state of deterioration of the building. It is often done. Specifically, a depreciation period under tax law (for example, 22 years) that is significantly shorter than the actual useful life of a building is sometimes used as the assumed useful life. If the number of years that have passed since construction exceeds this estimated useful life, the remaining useful life of the building is uniformly judged to be zero, the building is judged to have no value, and the owner cannot receive a loan from a financial institution. was there.

The present invention has been made in view of the above-mentioned circumstances, and takes into account the recovery of the remaining useful life due to renewal (for example, renovation or additional investment) with respect to the evaluation target such as equipment (facilities), and the actual evaluation of the equipment to be evaluated.

The effects obtained by the equipment evaluation device 1 according to the present embodiment described above will be explained.

FIG. 8 is a graph showing an example of a change in the equipment evaluation value calculated by the equipment evaluation device 1 according to the present embodiment.

In FIG. 8, the horizontal axis represents elapsed time, and the vertical axis represents evaluation amount. The appraised value on the vertical axis is based on the appraised value at the time of new construction as 100%.

When determining the equipment evaluation value using only the legal useful life, the equipment evaluation value becomes zero after the legal useful life has elapsed.

However, the actual useful life of the equipment is longer than the legal useful life, and even if the legal useful life has passed, the equipment can still be used and has value in many cases. In this way, it is not appropriate to evaluate the assessed value of usable equipment as zero.

In this embodiment, when a member constituting the equipment to be evaluated is updated, the service life of the updated member is extended, and the assessed value of the equipment to be evaluated is increased in accordance with the update. As a result, the value of the equipment being evaluated is recognized for a long period of time.

In the example of FIG. 8, regarding the renewal of the member P1, a member having the same service life before and after the renewal is used. The equipment evaluation value increases when the member P1 is updated, and then decreases with the passage of time at the same slope as before the update.

Regarding the renewal of members P2 and P3, they are replaced with members that have a longer service life than before the renewal. As a result, the equipment evaluation value increases when the members P2 and P3 are updated, and thereafter, the rate of decrease in the equipment evaluation value after the update becomes smaller than the reduction rate in the equipment evaluation value before the update.

The equipment evaluation device 1 according to the present embodiment described above allows equipment to be appropriately evaluated even if the legal service life has passed. Therefore, the owner of the equipment can obtain a loan from a financial institution using the equipment whose legal useful life has passed as collateral, and can appropriately decide whether to update, manage, or sell the equipment.

In this embodiment, the service life can be switched for each location condition of the facility, and the facility evaluation value and the remaining service life of the facility can be calculated more appropriately.

Note that the present invention is not limited to the embodiments described above, and each embodiment can be implemented by deleting, adding, or changing components. Further, by appropriately combining or exchanging each component of each embodiment, it is possible to implement further different forms. In this way, even if the embodiment is directly different from the embodiment described above, if it has the same meaning as the present invention, it will be treated as an embodiment of the present invention, and the explanation thereof will be omitted. There is.
