Description

{PRIORITY DECISION SUPPORT METHOD USING UTILIZATION BASED BUILDING ASSET MANAGEMENT}

The present invention relates to a method of supporting investment priority decision making in repair and maintenance work such as repair, maintenance, or extension, wherein asset management techniques are applied to priority decision making, and based on actual utilization of building assets, It is also possible to estimate the business risk based on this.

Asset management for facilities such as buildings is an optimization system of decisions made during the life cycle of facilities consisting of acquisition, operation, maintenance, repair and repair, By applying the system, efficient allocation of resources to the individual assets constituting the facility, as well as the cost reduction of service level maintenance through preemptive investment, is aimed.

Especially, in the case of multi-use facilities such as public office, station, department store, or theater, damage to property or loss of service may result in loss of life and damage to social functions such as life, transportation and administration. In addition, it is time consuming and costly to normalize post-repair or service, and asset management techniques are used to build and manage buildings to identify risk factors in advance and prioritize input of available resources. Various attempts have been made to enable efficient execution, and related related art is disclosed in Japanese Patent Laid-Open No. 2010-76708.

The conventional facility asset management method including the patent No. 2010-76708 is to quantify the deterioration of the relevant facilities such as a building and judge whether or not the facility is repaired based on the numerical value. As a matter of fact, This is a passive decision support method in which the oldness is calculated and thus the investment is simply determined.

In other words, in the method of supporting prioritized investment decision through the conventional building asset management, only the aging degree which is simply calculated according to the acquisition point and the specification of the asset in a state in which the utilization of the asset which is changed according to social factors and geographical conditions is ignored It can be said that there is no significant difference from the facility deterioration model and the estimation of the available life span in general facility management techniques before the introduction of the asset management system, The effect that can be achieved through allocation of available resources and prioritization of resources input using building asset management techniques has been extremely limited.

In particular, building assets are defined as the amount of utilization (utilization) of assets that can be changed from time to time by the social and economic factors rather than the cost of acquisition and the estimated value at the time of acquiring the actual value of the asset and the degree of damage It is necessary to apply it as a main factor in setting the building asset management method. However, the conventional method of building asset management has focused on the systematic management of individual asset information, but the actual utilization is not fully considered.

As a measure to measure and apply the actual utilization of the building in the building asset management, it is possible to consider a periodical survey of the utilization personnel, but it requires not only a large-scale manpower and a great expense, but also an intermittent investigation It is impossible to constantly investigate the whole of the huge building assets.

In particular, the conventional building asset management method, as described above, determines investment priority by simply applying the aging degree of each building asset. As a result, unnecessary measures are performed only because the degree of utilization is low, In addition to wasting huge amounts of money and increasing utilization rate and thus accelerating the rate of retirement, due to the lack of appropriate preemptive measures, the performance of the asset is not fully realized and the level of service is rapidly deteriorated. , Causing serious damage economically.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a priority decision support method through building asset management which is processed by a computer program, A management server 40 connected to the management database 45 and connected to the wireless network 30 via the Internet, a beacon 10 installed in a building asset and transmitting identification information, A beacon sending step (S10) of sending a beacon (10) installed in a building asset to the wireless network (30) capable of accessing the wireless network (30) (S21) for accessing the management server (40) via the network and requesting the installation of the application.

The management server 40 may be output through an output device directly connected to the management server 40, 40), the same screen can be output even when the asset management program is executed.

3 is a diagram showing a building asset extracted from the management database 45 as an asset management program is executed in a map format. FIG. 4 is a diagram showing an example of the asset information extracted from the management database 45, that is, identification information, The history information is displayed in a list format.

As illustrated in FIG. 4, in the present invention, inherent identification information is given to the building asset, and history information such as specification information such as the floor area (building area), the structure type and the number of floors of the building property, And is recorded in the management database 45 as information.

As described above, a beacon 10 for broadcasting and transmitting identification information assigned for each asset is installed for each asset. As shown in FIG. 5, the beacon 10 is provided on the map output by the asset management program of the present invention management server 40 The location of the building asset in which the beacon 10 is installed can be confirmed as well as the appearance of the building asset can be confirmed.

As shown in the flowchart of FIG. 6, the present invention performed through such a configuration starts with a beacon sending step (S10) in which a beacon 10 installed in a building asset transmits identification information.

As shown in FIG. 7, the signal transmitted in the beacon sending step S10 is transmitted in a broadcast manner without specifying a destination, and is periodically repeatedly transmitted. In the beacon sending step S10, Regardless of the performance of the present invention leading to the initial connection step S21 to the risk degree calculation step S63 to be described later, the beacon 10 can be used over a lifetime of the beacon 10 reaching the usable life of the beacon 10 It is done continuously.

6 and 7, the mobile terminal 20 accesses the management server 40 through the wireless network 30 and requests an application installation. In the initial connection step S21, The application installation information is transmitted to the mobile terminal 20 and the installation step S22 is performed in which the mobile terminal 20 receives the application installation information and the operating system of the mobile terminal 20 installs the application.

In the present invention, an application is a program that detects a beacon 10 transmission signal, receives and processes identification information in the signal, converts it into utilization information to be described later, and transmits it to the management server 40, (20) is loaded as an operating system application format.

The mobile terminal 20 of the present invention application is completed by the user of the mobile terminal 20 receiving the installation file of the application from the management server 40 and installing the installation file on the mobile terminal 20 of the mobile terminal 20, 20, it is assumed that the active connection of the user is presumed. However, at present, most of the mobile terminals 20 perform a batch process of accessing the server or downloading the program through a relatively simple operation such as touching the link included in the text message It is possible to perform the initial connection step S21 and the installation step S22 without complicated operations by the user.

However, it is preferable that the initial connection step S21 and the installation step S22 are performed on the premise of the user's consent, and such user consent can be secured in a manner of giving appropriate compensation or benefit to the participating users.

The mobile terminal 20 according to the present invention is a communication device such as a smart phone possessed by a general citizen or a building occupant who is a user of building assets and participates in the initial connection step S21 and the installation step S22 The user who installs the application in his / her mobile terminal 20 is encouraged to participate in such a manner as to give an economic cost such as a reduction in the use fee.

That is, the present invention can be performed by a public institution that manages a plurality of public buildings such as a public office or a station, or can be performed by an operator such as a department store or a theater having a plurality of branches, Or a reduction in the use fee, etc., thereby enabling the active participation of building users.

The mobile terminal 20 that has completed the installation step S22 is in a state where it can always detect the transmission signal of the beacon 10 so that the mobile terminal 20 can detect the transmission signal of the beacon 10 An information generation step S32 for receiving the identification information sent from the mobile terminal 20, an information generation step S32 for generating usage information by merging the identification information and the time information with the application of the mobile terminal 20, An information transmission step S40 is performed in which the mobile terminal 20 transmits usage information to the management server 40 through the wireless network 30. [

The signal detection step S31 is performed as a holder of the mobile terminal 20 passes through a building entrance or the like where the beacon 10 is installed and the holder of the mobile terminal 20 detects the signal of the beacon 10 As described above, the identification information transmitted from the beacon 10 is a simple string or numeric string, and the process performed in the information generation step S32, which is performed subsequently, And merges to generate usage information of a simple string or numeric column format. Therefore, there is no inconvenience for the user of the mobile terminal 20 to experience the experience of the mobile terminal 20 because the computational resources of the mobile terminal 20 are immovable.

The communication between the mobile terminal 20 and the beacon 10 is merely a one-time reception of the broadcasting of the beacon 10 by the mobile terminal 20, and the path thereof is not limited to the normal mobile communication network or the wireless network 30 The increase in the communication load is extremely small and no user inconvenience occurs in general use of the mobile terminal 20 such as a call and an Internet connection.

However, in performing the information transmission step S40 in which the mobile terminal 20 transmits the usage information to the management server 40 through the wireless network 30, temporary occupation of the wireless network 30 may occur , The transmission of the usage information that the user does not want can be performed. In the present invention, as shown in FIG. 8, the storage step S41 to the approval transfer step S43 are established to solve this problem.

That is, in the embodiment of FIG. 8, the information transmission step S40 is not performed immediately after the information generation step S32, but the application of the mobile terminal 20 transmits the usage information generated in the information generation step S32 to the mobile terminal After the mobile terminal 20 enters the pre-designated wireless network 30 after the storing step S41 of storing the mobile terminal 20 in the storage device of the mobile terminal 20, the application outputs a usage information list and a transmission confirmation message on the touch screen (Step S42), and if the touch screen of the mobile terminal 20 is operated and the transmission is accepted, the application transmits the usage information to the management server 40 through the wireless network 30 (S43) is performed, so that the utilization information is provided to the management server 40 only.

The pre-designated wireless network 30 in the doctor confirmation step S42 is a free wireless network 30 that does not cause a communication fee to be charged as a wireless network 30 designated by the user in advance, In order to minimize the inconvenience caused by the occupation of the wireless network 30, it is also possible to collectively transmit the stored usage information by setting the transmission time in advance such as the night time have.

As shown in FIG. 8, in the pseudo-confirmation step (S42), a list of usage information to be transmitted is output and a user's intention is searched. If the user does not want to transmit, the transmission of the corresponding usage information is withdrawn, Is deleted to protect the privacy of the user as much as possible.

7 and 8, when the usage information is provided to the management server 40, the management server 40 receives the usage information and records it in the management database 45 as shown in FIG. 6 (Step S50) is performed, and the utilization information is accumulated in the management database 45. [0064]

The usage information in the present invention is not information on all users who use the building asset but may be information on usage information of some users who have participated in their own will and installed the application on their mobile terminal 20 The total utilization of the building assets can not be measured quantitatively, but it is statistically meaningful to use the sample users. Therefore, the relative utilization of individual building assets to be managed by asset management Can be sufficiently employed.

FIG. 9 illustrates a state in which the utilization information of the collected building assets is stored in the management database 45. As shown in the list in FIG. 9, the monthly usage amount, the annual usage amount, and the cumulative use amount Is displayed.

The utilization information of the specific building asset is used to calculate the damage caused by the destruction of the asset. The management server 40 fetches the asset information and the usage information from the management database 45 and sets the degree of damage according to the utilization information Is also performed through the setting step S61.

In other words, the damages are also set high for building assets with relatively high utilization in the utilization information, and the damages are also set low in the case of building assets with relatively low utilization.

The damage level setting step S21 is a preliminary action for performing a risk calculating step S23 to be described later. Also, as a preliminary action preceding the risk calculating step S23, the history information for each asset is fetched, And a failure probability setting step S22 in which a failure probability according to the failure probability is set.

The probability of failure is the probability that an asset will be destroyed at the present time, as in the dictionary meaning, and the probability of destruction is set by using the period of use for the normal life of the asset as a main factor.

Then, as shown in FIG. 10, the risk level is calculated by combining the degree of damage and the probability of failure of the management server 40, and the risk degree calculation step S63 is recorded in the management database 45 as shown in FIG. 11, Management of building assets considering practical utilization and priority decision support through this.

Damage in the damage setting step S21 and failure probability in the failure probability setting step S22 are given in a rating format as shown in FIG. 10, In step S63, the risk is calculated in four steps of L (low risk), M (medium risk), S (sufficient risk) and H (high risk).

In the present invention, in setting the damage degree in the damage setting step (S21), utilization of the building asset based on utilization information is reflected, and accordingly, as shown in FIG. 11, And the risk is also increased.
