The asset evaluation information including the evaluation value is registered in the evaluation value management DB 213.

The asset evaluation value is, for example, a value based on an evaluation value indicating the evaluation of the evaluation target asset itself, which is the evaluation target asset, and the degree of influence of other assets on the evaluation target asset. In addition, the asset evaluation value may be further based on the degree of influence of the infrastructure network (road, water network, etc.) on the asset to be evaluated, or information described in a hazard map or the like predetermined for each asset (hazard map, etc.). It may be based on unique information such as (disaster risk level, etc.). Further, the asset evaluation value may include an evaluation value indicating the degree of positive evaluation (such as the value of the asset) for the asset and an evaluation value indicating the degree of negative evaluation (such as the risk of the asset) for the asset. ..

The measure evaluation value calculation unit 210 registers the measure information indicating the measure for the asset in the measure management DB 215. Further, the measure evaluation value calculation unit 210 evaluates the measure for the asset based on the measure information and the asset data and the attribute data stored in the asset management unit 109.
As measures for assets, in this embodiment, addition (new establishment) of assets, deletion (removal) of assets, and diversion of assets (change of use (type)) will be described, but other measures may be used. Other asset-related measures include asset maintenance, investment, value enhancement, and selection of other businesses to collaborate with.

In addition, as the measure information, there are those in which the measure target asset to be the target of the measure is set, and those in which a plurality of measure candidate assets to be candidates for the measure target asset and a target value for the evaluation value are set. When the measure information sets the measure target asset, the measure evaluation value calculation unit 210 evaluates the measure, calculates the measure evaluation value indicating the evaluation of the measure, and outputs the measure evaluation information including the measure evaluation value. Register in the evaluation value management DB 213. In addition, when the measure information sets the measure candidate asset and the target value, the measure evaluation value calculation unit 210 evaluates a plurality of measure candidate assets based on the target value, and sets the evaluation result and the target value as the evaluation result and the target value. Based on this, select the recommended measure target asset recommended as the measure target asset from multiple measure candidate assets.

The area evaluation value calculation unit 211 evaluates the evaluation target area including the asset based on the asset data and the attribute data stored in the asset management unit 109, generates an area evaluation value indicating the evaluation of the area, and generates the area evaluation value, and the area is generated. Area evaluation information including the evaluation value is registered in the evaluation value management DB 213. Further, when the user specifies an area to be compared or imitated, or when a target value of the area evaluation value is specified, the area evaluation value calculation unit 211 is evaluated based on the evaluation value of the evaluation target area. You may present the necessary assets for. The area may be an administrative area such as a municipality, or may be an area independently set by the city asset management system 101 or a user.

The index management unit 212 registers management information indicating criteria for evaluating evaluation targets such as assets, measures, and areas in the evaluation index management DB 214, which is a storage unit. The management information is, for example, an evaluation showing the correspondence between the impact management information showing the relationship between each asset (for example, the influence relationship on the evaluation of each asset) and the evaluation standard for evaluating the type of each asset and the evaluation target. Includes indicator information. The evaluation criteria include an evaluation index that is a type of evaluation value and an evaluation formula for calculating the evaluation value of the evaluation index.

In addition, the index management unit 212 collects the collected data such as dynamic data and statistical values collected by the data collection / management unit 108, and the evaluation value registered in the evaluation value management DB 213 (for example, the same asset as the actual one is placed in the same place). The evaluation criteria may be updated based on the evaluation value when a new establishment is taken as a measure). For example, the index management unit 212 updates the evaluation calculation formula and the values of its parameters.

The user management unit 111 includes a user authentication unit 216, a usage management unit 217, a user management DB 218, and a data usage management DB 219. The user authentication unit 216 registers user information about the user such as authentication information (for example, user ID and password) in the user management DB 218, and performs access authentication of the user terminals 106 and 107 based on the user information. .. The usage management unit 217 registers data usage information related to the usage of various data used in the city asset management system 101 in the data usage management DB 219, and based on the data usage information, whether or not to generate and provide data is determined. judge. The data usage information indicates, for example, a user who can use various data, a user's usage log for various data, and the like.

The application management unit 112 has an asset monitoring application unit 220, an asset evaluation application unit 221, a measure evaluation application unit 222, and an area evaluation application unit 223.

The asset evaluation application unit 221 evaluates the evaluation target asset using the asset evaluation unit 110, and presents the asset evaluation value, which is the evaluation result, to the user. The measure evaluation application unit 222 evaluates a measure using the asset evaluation unit 110, and presents a measure evaluation value or a recommended measure target asset to the user as the evaluation result. The area evaluation application unit 223 evaluates the evaluation target area using the asset evaluation unit 110, and the asset evaluation application unit 221 presents the area evaluation value, which is the evaluation result, to the user.

The interface unit 113 provides, for example, a menu selection screen 224, an information input screen 225, and an information display screen 226 as screens for the user to input information to the user terminals 106 and 107. The menu selection screen 224 is a screen for selecting a function to be used by the user from the functions that can be provided by the city asset management system 101. The information input screen 225 is a screen for receiving an information display request or the like from a user. The information display screen 226 is a screen for presenting information provided by the application management unit 112.

FIG. 3 is a sequence diagram for explaining an example of an asset registration process for registering asset data and attribute data, and an asset monitoring process for presenting asset data and attribute data to a user.

In the asset registration process, first, the data collection unit 201 of the data collection / management unit 108 collects various data from the external systems 102 and 103 and the sensors 104 and 105 via the network 114 (step S301). The data management unit 202 registers and saves the collected data collected by the data collection unit 201 in the data management DB 203 (step S302).

Subsequently, the asset data management unit 204 of the asset management unit 109 acquires asset data from the collected data stored in the data management DB 203 of the data collection / management unit 108 and stores it in the asset management DB 207 (step S303). Further, the attribute management unit 205 generates attribute data based on the collected data and stores it in the attribute information DB 208 (step S304).

On the other hand, in the asset monitoring process, when the user terminal 106 or 107 first inputs authentication information into the city asset management system 101 via the interface unit 113 and logs in (step S305), the user authentication unit 216 of the user management unit 111 , Access authentication of the user terminal 106 or 107 is performed based on the input authentication information and the user information stored in the user management DB 218 (step S306). If the access authentication is successful, the interface unit 113 displays the menu selection screen 224 on the user terminal 106 or 107 (step S307).

Here, it is assumed that the user has selected "asset monitoring" for confirming the asset data as a function to be used by using the menu selection screen 224. At this time, the asset to be confirmed may be selected.

In this case, the asset monitoring application unit 220 of the application management unit 112 requests the data providing unit 206 of the asset management unit 109 to provide the asset data (step S308). In response to the request, the data providing unit 206 extracts the asset data and the attribute data related to the asset to be confirmed from the data management DB 203 and the attribute information DB 208 and transmits them to the interface unit 113 via the asset monitoring application unit 220. (Step S309). When the interface unit 113 receives the asset data and the attribute data, the interface unit 113 provides the asset data and the attribute data to the user terminal 106 or 107 using the information display screen 226 (step S310).

Further, the usage management unit 217 of the user management unit 111 registers the user usage log in the data usage management DB 219 (step S311).

FIG. 4 is a sequence diagram for explaining an example of an asset evaluation process for evaluating an asset. The asset evaluation process is executed, for example, when "asset evaluation" is selected using the menu selection screen 224 displayed in step S307 described with reference to FIG.

In the asset evaluation process, the asset evaluation application unit 221 of the application management unit 112 requests the data providing unit 206 of the asset management unit 109 to provide the asset data (step S401). In response to the request, the data providing unit 206 extracts the asset data and the attribute data related to the asset to be confirmed from the data management DB 203 and the attribute information DB 208 and transmits them to the interface unit 113 via the asset evaluation application unit 221. (Step S402). When the interface unit 113 receives the asset data and the attribute data, the interface unit 113 provides the asset data and the attribute data to the user terminal 106 or 107 using the information display screen 226 (step S403). Here, the usage management unit 217 of the user management unit 111 may register the user usage log in the data usage management DB 219.

After that, when the user specifies the evaluation target asset using the information display screen 226, the asset evaluation application unit 221 instructs the asset evaluation value calculation unit 209 of the asset evaluation unit 110 to execute the evaluation of the evaluation target asset (step S404). ). Then, the asset evaluation value calculation unit 209 executes an asset evaluation value calculation process for evaluating the evaluation target asset, generates asset evaluation information, and transmits the asset evaluation information to the interface unit 113 via the asset evaluation application unit 221 (step S405). ). When the interface unit 113 receives the asset evaluation information, the interface unit 113 provides the asset evaluation information to the user terminal 106 or 107 using the information display screen 226 (step S406).

FIG. 5 is a flowchart showing an example of the asset evaluation value calculation process in step S405.

In the asset evaluation value calculation process, first, the asset evaluation value calculation unit 209 sets an evaluation index corresponding to the type of the evaluation target asset as a target evaluation index based on the evaluation index information stored in the evaluation index management DB 214 (. Step S451). Evaluation indicators include, for example, welfare power calculated from the positional relationship with assets such as medical facilities and facilities for the elderly, congestion degree calculated from the number of people and vehicles within a certain distance from the assets, and capacity of the assets to be evaluated. Ability to attract customers calculated from the capacity and positional relationship between the city (accommodation scale, etc.) and surrounding assets such as apartments and stations, the number of crimes around the assets to be evaluated and the position of peripheral assets such as police facilities and entertainment facilities Security level calculated from the relationship, convenience calculated from the positional relationship with peripheral assets such as retail facilities and stations, hazard map values around the asset to be evaluated (inundation 3 m, etc.) and peripheral assets such as evacuation facilities The degree of disaster prevention calculated from the positional relationship can be mentioned. In addition, the evaluation index may be a comprehensive index such as livability calculated from welfare power, security, and convenience. There may be a plurality of target evaluation indexes.

Subsequently, the asset evaluation value calculation unit 209 determines an evaluation calculation formula for calculating the asset evaluation value of the target evaluation index as the target evaluation calculation formula based on the evaluation index information stored in the evaluation index management DB 214 (. Step S452).

Further, the asset evaluation value calculation unit 209 evaluates the evaluation target asset by the target evaluation index based on the asset data of the evaluation target asset stored in the asset management DB 207 and the management information stored in the evaluation index management DB 214. An influential asset that has an influence is specified, and the asset data and the attribute data of the influential asset are extracted from the asset management DB 207 and the attribute management DB 208 as related data (step S453). The impact asset is, for example, an asset whose distance from the evaluation target asset is within a predetermined distance and which is defined in the impact management information to affect the measure target asset. The predetermined distance is set by the user, for example. Further, the predetermined distance may not be set. In this case, the impact asset is an asset that is in the area including the evaluation target asset and is specified in the impact management information to affect the measure target asset. The distance between the assets may be a straight line distance or a distance along the road.

Further, the asset evaluation value calculation unit 209 calculates the asset evaluation value of the evaluation target asset based on the asset data and attribute data of the evaluation target asset, the related data, and the target evaluation calculation formula (step S454). Then, the asset evaluation value calculation unit 209 registers the asset evaluation information including the asset evaluation value in the evaluation value management DB 213 (step S455). The asset evaluation information may further include at least a part of measure information, evaluation target assets and related data.

In addition, there may be a plurality of target evaluation calculation formulas for the same target evaluation index. For example, there may be a plurality of target evaluation formulas for calculating the asset evaluation value for each time zone for the same target index. In this case, the asset evaluation value calculation unit 209 calculates the asset evaluation value for each target evaluation calculation formula.

The evaluation calculation formula is, for example, the following formula (1).

The first term of the equation (1) shows the contribution of the evaluation target asset itself to the asset evaluation value A of the evaluation target asset. Here, "S _x " is a parameter calculated from the capacity of the evaluation target asset and the dynamic data related to the evaluation target asset. If the evaluation target asset itself does not affect the asset evaluation value A, the first term is 0.

The second term of the equation (1) shows the contribution of the influence asset to the asset evaluation value A of the evaluation target asset. Here, " _a " is the type of affected asset, "m" is the number of affected assets, " _dak " is the distance between the evaluated asset and the affected asset, and "wa" is the affected asset. It is a coefficient indicating the magnitude of the influence on the asset evaluation value A according to the type _a , and "pa" is the attribute value (value set according to the attribute data such as the number of beds) of the influence asset of the type a. It is a coefficient indicating the magnitude of the influence on the asset evaluation value A according to it, and "v _a " indicates the magnitude of the influence on the asset evaluation value A according to the distance between the influence asset of type a and the asset to be evaluated. It is a coefficient, and "n" is the number of types of affected assets. Therefore, for example, when there are a plurality of affected assets, the degree of influence on the asset evaluation value A is calculated for each affected asset, and the total sum is the value of the second term.

The third term of the equation (1) shows the contribution of the infrastructure network to the asset evaluation value A of the asset to be evaluated. Infrastructure networks are, for example, roads and water networks. "W _r " is a coefficient indicating the magnitude of the influence of the infrastructure network on the asset evaluation value A, "d _rk " is the distance between the asset to be evaluated and the nearest infrastructure network, and "v _r " is the evaluation target. It is a coefficient indicating the magnitude of the influence of the distance between the asset and the nearest infrastructure network on the asset evaluation value A. If there is no infrastructure network for the asset evaluation value A of the asset to be evaluated, the third term is 0.

The fourth term of the formula (1) is a constant term corresponding to the brand value of the asset to be evaluated and the value unique to the asset such as the disaster risk set based on the hazard map or the like. The fourth term may be 0.

FIG. 6 is a sequence diagram for explaining an example of a measure evaluation process for evaluating measures related to assets. The measure evaluation process is executed, for example, when the measure evaluation is selected by using the menu selection screen 224 displayed in step S307 described with reference to FIG.

In the measure evaluation process, first, the measure evaluation application unit 222 of the application management unit 112 requests the data providing unit 206 of the asset management unit 109 to provide the asset data (step S501). In response to the request, the data providing unit 206 extracts the asset data and the attribute data related to the asset to be confirmed from the data management DB 203 and the attribute information DB 208 and transmits them to the interface unit 113 via the measure evaluation application unit 222. (Step S502). When the interface unit 113 receives the asset data and the attribute data, the interface unit 113 provides the asset data and the attribute data to the user terminal 106 or 107 using the information display screen 226 (step S503). Here, the usage management unit 217 of the user management unit 111 may register the user usage log in the data usage management DB 219.

After that, when the user inputs the measure information indicating the evaluation target measure using the information display screen 226, the measure evaluation application unit 222 instructs the measure evaluation value calculation unit 210 of the asset evaluation unit 110 to execute the evaluation of the evaluation target measure. (Step S504). Then, the measure evaluation value calculation unit 210 executes the measure evaluation value calculation process for evaluating the evaluation target measure, generates the measure evaluation information, and transmits the measure evaluation information to the interface unit 113 via the measure evaluation application unit 222 (step S505). ). When the interface unit 113 receives the measure evaluation information, the interface unit 113 provides the measure evaluation information to the user terminal 106 or 107 using the information display screen 226 (step S506).

FIG. 7 is a flowchart showing an example of the measure evaluation value calculation process in step S505. The measure evaluation value calculation process includes a first measure evaluation value calculation process for calculating the measure evaluation value of the measure target asset and a second measure evaluation value calculation process for selecting a recommended measure target asset from a plurality of measure candidate assets. include. In this embodiment, in the second measure evaluation value calculation process, the recommended measure target asset is selected based on the target value.

In the measure evaluation value calculation process, first, the measure evaluation value calculation unit 210 determines whether or not the target value is included in the measure information (step S601). If the target value is not included, the first measure evaluation value calculation process (steps S602 to S606) is executed, and if the target value is included, the second measure evaluation value calculation process (steps S607 to S609) is executed. Is executed.

In the first measure evaluation value calculation process, the measure evaluation value calculation unit 210 determines whether or not the measure to be evaluated is the deletion of the asset based on the measure information (step S602).

When the measure to be evaluated is not the deletion of the asset, the measure evaluation value calculation unit 210 causes the asset evaluation value calculation unit 209 to execute the asset evaluation value calculation process using the measure target asset as the evaluation target asset, and evaluates the measure target asset. Calculate the value (step S603). When the measure to be evaluated is the deletion of the asset, the measure evaluation value calculation unit 210 skips the process of step S603.

The measure evaluation value calculation unit 210 is an asset to which the measure target asset has an influence in the evaluation based on the measure target evaluation standard corresponding to the type of the measure target asset based on the impact management information stored in the evaluation index management DB 214. Identify impact assets. The measure evaluation value calculation unit 210 causes the asset evaluation value calculation unit 209 to execute an asset evaluation value calculation process using the affected asset as the evaluation target asset for each affected asset, and after the measure of each affected asset. Calculate the affected asset valuation value after the measure, which is the asset valuation value (asset valuation value based on the data of the measure target asset after the measure is taken). Then, the measure evaluation value calculation unit 210 determines the affected asset evaluation value after the measure and the affected asset evaluation value before the measure (asset evaluation based on the data of the measure target asset before the measure is taken) for each affected asset. The difference from the value) is calculated (step S604).

The affected asset is, for example, an asset whose distance from the target asset is within a predetermined distance and which is defined by the impact management information to be affected by the target asset. The affected asset evaluation value before the measure can be the asset evaluation value if the asset evaluation value calculation unit 209 registers the asset evaluation value of the affected asset in the evaluation value management unit DB 213 in the above-mentioned asset evaluation process or the like. Alternatively, the asset evaluation value calculation unit 209 may be made to calculate in step S604 in the same manner as the affected asset evaluation value after the measure.

The measure evaluation value calculation unit 210 causes the area evaluation value calculation unit 211 to execute the area evaluation value calculation process described later with the measure target area including the measure target asset as the evaluation target area, and evaluates the area after the measure of the measure target area. Calculate the value. The measure evaluation value calculation unit 210 and the measure evaluation value calculation unit 210 calculate the difference between the area evaluation value after the measure in the measure target area and the area evaluation value before the measure in the measure target area (step S605). The area evaluation value calculation process will be described later with reference to FIG. If the area evaluation value before the measure is registered in the evaluation value management unit DB 213, the area evaluation value may be used, or the area evaluation value calculation unit 209 may calculate the area evaluation value in step S605 in the same manner as the area evaluation value after the measure. May be good.

The measure evaluation value calculation unit 210 includes at least one of the asset evaluation value of the measure target asset, the difference between the affected asset evaluation value before and after the measure, and the difference between the area evaluation value before and after the measure as the measure evaluation information. Is generated and registered in the measure management DB 215 (step S606). The measure evaluation information may further include the measure information, the measure target asset evaluation value, the affected asset evaluation value before and after the measure, the area evaluation value before and after the measure, and the like. Further, the measure evaluation value may be a measure target asset evaluation value, an affected asset evaluation value after the measure, an area evaluation value after the measure, or the like.

On the other hand, in the second measure evaluation value calculation process, the measure evaluation value calculation unit 210 sets any of the measure candidate assets indicated by the measure information as a provisional measure target asset (step S607).

After that, the measure evaluation value calculation unit 210 executes steps S602B to S605B, which are the same processes as steps S602 to S605. However, when the measure is the diversion of the asset, not only the type of the asset may be changed, but also the area evaluation value may be calculated after the measure is deleted when the asset is deleted.

The measure evaluation value calculation unit 210 calculates the measure evaluation value (the asset evaluation value of the measure target asset, the difference between the affected asset evaluation value before and after the measure, and the difference between the area evaluation value before and after the measure) for all the measure candidate assets. It is determined whether or not the evaluation is completed, and it is determined whether or not the evaluation is completed (step S608).

If the evaluation of the measure is not completed, the measure evaluation value calculation unit 210 returns to step S607 and changes the measure target asset to another measure candidate asset. On the other hand, when the evaluation of the measure is completed, the measure evaluation value calculation unit 210 selects the recommended measure target asset from the measure candidate assets based on each measure evaluation value and the target value, and selects the recommended measure target asset. The measure evaluation information including the measure evaluation value is generated and registered in the measure management DB 215 (step S609).

Recommended measure target assets are, for example, measure candidate assets whose difference between the measure evaluation value and the target value is less than or equal to the standard value, measure candidate assets whose measure evaluation value exceeds the target value, or measures whose measure evaluation value is below the target value. Candidate assets, etc. In this embodiment, the target value is the target value for the difference between the area evaluation values, but it may be the target value for the area evaluation value itself, the asset evaluation value of the target asset, the affected asset evaluation value, or theirs. It may be a target value for a difference or the like.

In step S608, the recommended measure target asset has at least one of the difference between the affected asset evaluation value before and after the measure and the difference between the area evaluation value before and after the measure as the measure evaluation value, and the measure evaluation value and the target value. Based on the above, it may be determined whether or not to end the evaluation of the measure. For example, in the measure evaluation value calculation unit 210, when the difference between the measure evaluation value and the target value is equal to or less than the standard value, the measure evaluation value exceeds the target value, or the measure evaluation value falls below the target value. In some cases, it is judged that the evaluation of the measures will be completed. In this case, the measure candidate asset currently set as the measure target asset becomes the recommended measure target asset. Further, the measure candidate asset having the highest predetermined measure evaluation value such as the area evaluation value may be selected as the recommended measure target asset without setting the target value.

FIG. 8 is a sequence diagram for explaining an example of the area evaluation process for evaluating the area. The measure evaluation process is executed, for example, when the area evaluation is selected using the menu selection screen 224 displayed in step S307 described with reference to FIG.

In the area evaluation process, first, the area evaluation application unit 223 of the application management unit 112 requests the data providing unit 206 of the asset management unit 109 to provide the asset data (step S701). In response to the request, the data providing unit 206 extracts the asset data and the attribute data related to the asset to be confirmed from the data management DB 203 and the attribute information DB 208 and transmits them to the interface unit 113 via the area evaluation application unit 223. (Step S702). When the interface unit 113 receives the asset data and the attribute data, the interface unit 113 provides the asset data and the attribute data to the user terminal 106 or 107 using the information display screen 226 (step S703). Here, the usage management unit 217 of the user management unit 111 may register the user usage log in the data usage management DB 219.

After that, when the user inputs the area information indicating the evaluation target area using the information display screen 226, the area evaluation application unit 223 instructs the area evaluation value calculation unit 211 of the asset evaluation unit 110 to execute the evaluation of the evaluation target measure. (Step S704). Then, the area evaluation value calculation unit 211 executes an area evaluation value calculation process for evaluating the evaluation target area, generates an area evaluation value, and transmits the area evaluation value to the interface unit 113 via the area evaluation application unit 223 (step S705). ). When the interface unit 113 receives the area evaluation value, the interface unit 113 provides the area evaluation value to the user terminal 106 or 107 using the information display screen 226 (step S706).

FIG. 9 is a flowchart showing an example of the area evaluation value calculation process in step S705.

In the area evaluation value calculation process, first, the area evaluation value calculation unit 211 sets a predetermined evaluation index for evaluating the evaluation target area as the target area evaluation index (step S801). For example, the area evaluation value calculation unit 211 sets the “area welfare ability” in the record 983 of the evaluation index information 940 of the evaluation index management DB 214 of FIG. 16 to be described later as the target area evaluation index.

Subsequently, the area evaluation value calculation unit 211 determines an evaluation calculation formula for calculating the area evaluation value of the target area evaluation index as the target area evaluation calculation formula based on the evaluation index information stored in the evaluation index management DB 214. (Step S802).

Further, the area evaluation value calculation unit 211 is evaluated by the target area evaluation index based on the asset data of the assets in the evaluation target area stored in the asset management DB 207 and the management information stored in the evaluation index management DB 214. The area influence asset that affects the evaluation of the area is specified, and the asset data and the attribute data of the area influence asset are extracted from the asset management DB 207 and the attribute management DB 208 as area-related data (step S803). The area impact asset is, for example, an asset that is included in the area corresponding to the evaluation target area and is defined in the impact management information to affect the measure target area. The area corresponding to the evaluation target area may be the evaluation target area itself, or may be within a circular area having a predetermined radius from a predetermined point (for example, the center) in the evaluation target area.

Further, the area evaluation value calculation unit 211 calculates the area evaluation value of the evaluation target area based on the target area evaluation calculation formula and the area-related data (step S804). Then, the area evaluation value calculation unit 211 registers the area evaluation information including the area evaluation value in the evaluation value management DB 213 (step S805). The area evaluation information may further include at least a part of measure information and area-related data.

When the target value of the area evaluation value is specified, the area evaluation value calculation unit 211 reaches the target value based on the area evaluation information and the target value registered in the evaluation value management DB 213. If not, the type and number of assets missing in the area may be estimated (step S806). The target value may be set directly by the user, or may be set according to the comparison target area specified by the user or the comparison target area to be imitated. For example, the area evaluation value of the comparison target area may be set as the target value.

The target area evaluation calculation formula is, for example, the following formula (2).

The first term of the equation (2) shows the contribution of the area influence asset to the area evaluation value B of the evaluation target area. Here, " _a " is the type of area impact asset, "m" is the number of area impact assets, and "wa" is the magnitude of the effect on the area evaluation value B according to the area impact asset type a. "V _a " is the asset evaluation value of the evaluation index corresponding to the target area evaluation index of the area evaluation value B of the area influence asset of the type a, and "n" is the asset evaluation value of the area influence asset. Is the number of. Therefore, when there are a plurality of types of area influence assets, the degree of influence on the area evaluation value B is calculated for each type, and the total sum is the value of the first term. The evaluation index corresponding to the target area evaluation index is, for example, "welfare power" corresponding to "area welfare power".

The second term of equation (2) corresponds to statistical data such as water supply penetration rate and aging rate of the evaluation target area, and area-specific values such as disaster risk set based on hazard maps and the like. It is a constant term. The second term may be 0.

FIG. 10 is a sequence diagram for explaining an example of the index management process for managing the evaluation index.

In the index management process, the index management unit 212 is stored in the collected data stored in the data management DB 203, the asset data stored in the asset management DB 207, and the attribute information DB 208 via the data providing unit 206 of the asset management unit 109. Acquire attribute data (step S901). The index management unit 212 identifies the updated asset as an updated asset from each data, and acquires the asset evaluation value of the updated asset from the asset evaluation value calculation unit 209 as the measure evaluation value of the measure corresponding to the updated asset ( Step S902), the area evaluation value of the area including the updated asset is acquired from the area evaluation value calculation unit 211 (step S903). The index management unit 212 updates the evaluation index based on those evaluation values and actual values (for example, an increase in the ability to attract customers of peripheral assets after a certain asset is newly established) (step S904).

FIG. 11 is a flowchart for explaining the index management process more specifically.

First, the index management unit 212 is updated at a predetermined management timing based on the collected data stored in the data management DB 203, the asset data stored in the asset management DB 207, the attribute data stored in the attribute information DB 208, and the like. The updated asset, which is the asset, is specified (step S1001). The management timing is, for example, a periodic timing, a timing when the data of the asset management DB 207 or the attribute information DB 208 is updated, a timing when a request is made from the user terminal 106 or 107, or the like. Update assets are, for example, newly added assets, assets removed from the city, assets diverted, and so on.

Subsequently, the index management unit 212 acquires the actual value related to the updated asset based on the dynamic data and the statistical value in the collected data and the asset data and the attribute data (step S1002). The actual value is, for example, the rate of increase in the ability to attract customers of peripheral assets after the new establishment of the updated asset. , And the corresponding actual data.

Subsequently, the index management unit 212 evaluates the measures for which the updated assets are the target assets based on the asset data and the attribute data before the updated assets change, in the asset evaluation value calculation unit 209 and the area evaluation value calculation unit 211. Is executed, and the asset evaluation value, the affected asset evaluation value, the area evaluation value, and the like of the updated asset are calculated as the measure evaluation values (step S1003).

The index management unit 212 evaluates the consistency of the evaluation index information based on the measure evaluation value and the actual value (step S1004). For example, the index management unit 212 determines whether or not the difference between the area evaluation value in the measure evaluation value and the corresponding actual value is equal to or greater than the predetermined value, and if the difference is equal to or greater than the predetermined value, the index management unit 212 matches the evaluation index information. If it is judged that there is no property and the difference is less than the predetermined value, it is judged that the evaluation index information is consistent.

If there is no consistency, the index management unit 212 updates the evaluation index information (particularly, the evaluation calculation formula and parameters such as coefficients used in the evaluation calculation formula) based on the measure evaluation value and the actual value (step S1005). ). For example, the index management unit 212 changes the evaluation calculation formula and its parameters in a predetermined procedure until the difference between the area evaluation value and the actual value becomes less than a predetermined value.

18 to 21 are views showing an example of a display screen provided by the interface unit 113. Each display screen is composed of a menu selection screen 224, an information input screen 225, and an information display screen 226.

FIG. 18 is a diagram showing an example of an asset monitoring screen, which is a display screen displayed in step S310 of the asset monitoring process of FIG. In the asset monitoring screen shown in FIG. 18, "asset monitoring" is selected on the menu selection screen 224, and on the information input screen 225, the check box 1004 is used as the asset to be monitored, and the "station", "hospital", and "apartment housing" are used. Is selected. The check box 1004 is set according to the type of the asset registered in the asset management DB 207.

In this case, the interface unit 113 uses, for example, the symbol 1002 corresponding to the asset of the type “medical facility” registered in the record 881 of the asset management DB 207 shown in FIG. 13 based on the latitude / longitude information of the record 881. It is displayed on the map of the information display screen 226. Here, when the symbol 1002 is selected by the user, the interface unit 113 uses the record 883 of the attribute data 830 of the attribute information DB shown in FIG. 14 based on the attribute ID “00001” of the record 881 of the asset management DB 207. Attribute information is acquired from, and at least a part of the attribute information is displayed by the balloon 1003. For example, the slide bar 1005 may be displayed on the information input screen 225 so that the time of the data to be displayed can be selected.

FIG. 19 is a diagram showing an example of an asset evaluation screen, which is a display screen displayed in step S406 of the asset evaluation process of FIG. In the asset evaluation screen shown in FIG. 18, "asset evaluation" is selected on the menu selection screen 224.

On the asset evaluation screen, when the user selects the symbol displayed on the information display screen 226 or specifies the asset to be evaluated on the information input screen 227, the asset evaluation application unit 221 calculates the asset evaluation value of the asset evaluation unit 110. When the unit 209 is executed, the asset evaluation information is calculated, and the interface unit 113 displays the asset evaluation information on the information display screen 226.

For example, when the symbol 1102 (corresponding to the asset ID "00001") on the information display screen 226 is selected, the record 881 corresponding to the asset ID "00001" of the asset management DB 207 of FIG. The type "medical facility" is acquired, and a record in which "medical facility" is included in the calculation target type of the evaluation index information 940 of the evaluation index management DB 214 of FIG. 16 is acquired. Then, the target evaluation index is specified by the index ID and the index name of the record. For example, the evaluation index of record 981 (index ID “00001” and index name “welfare power”) and the evaluation index of record 982 (index ID “00002” and index name “customer attraction”) are specified as target evaluation indexes. ..

Subsequently, in step S452, the target evaluation calculation formula is determined by the evaluation formula ID of the target evaluation index. For example, for the target evaluation index of the index name "welfare ability", the evaluation calculation formula 902 (evaluation formula A) corresponding to the evaluation formula ID "00001" of the record 981 of the evaluation index information 940 of the evaluation index management DB 214 is the target. The evaluation formula 903 (evaluation formula) corresponding to the evaluation formula ID "00023" of the record 982 of the evaluation index information 940 of the evaluation index management DB 214 for the target evaluation index determined as the evaluation calculation formula and having the index name "customer attraction". B) is determined as the target evaluation calculation formula.

Subsequently, in step S453, the impact asset corresponding to the target evaluation index is specified, and the asset data and attribute data of the impact asset are extracted as related data.

For example, for the target evaluation index of the index name "welfare power", the asset ID "00001" of the evaluation target asset and the type "00001" of the evaluation target asset are used for the field 951 of the influence management information 950 of the evaluation index management DB 214 of FIG. A record corresponding to at least one of "medical facilities" and whose index ID 953 corresponds to the index ID "00001" of the index name "welfare ability" is extracted. Then, at least one of the affected asset, the type of the affected asset, and the asset ID is specified from the field 952 of the record. For example, when the record 984 of the impact management information 950 is extracted, the distance from the position indicated by the latitude / longitude information of the asset ID "00001" of the asset management DB 207 is within a predetermined distance, and the type is "apartment house". The asset is identified as an impact asset.

Similarly, for the target evaluation index of the index name “welfare power”, for example, records 985 and 986 are extracted, and the distance from the position indicated by the latitude / longitude information of the asset ID “00001” of the asset management DB 207. Is within a predetermined distance, and assets of the types "medical facility" and "retail facility" are specified as impact assets.

Further, in step S454, the asset evaluation value of the evaluation target asset is calculated based on the target evaluation calculation formula and the asset data and attribute data of the affected asset.

For example, for the target evaluation index with the index name “customer attraction”, the asset evaluation value is calculated from the target evaluation formula of the above-mentioned formula (1). In addition, in the second term of the formula (1), the degree of influence on the "customer attraction (asset evaluation value)" of the asset to be evaluated is calculated for each affected asset, and the total sum is the value of the second term, that is, all. The impact of the impact asset is calculated. At this time, the influence degree of each influence asset may be calculated by using, for example, the influence degree of the influence management information 941 of the evaluation index management DB 214 instead of calculating using the equation (1). The degree of influence on the ability to attract customers given by the asset to be evaluated may be acquired from the evaluation value management DB 213.

Subsequently, in step S455, an evaluation ID is assigned to the asset ID of the evaluation target asset, the target evaluation index and its asset evaluation value, the asset ID of the affected asset and its impact degree, and the evaluation value management DB 213 is assigned as asset evaluation information or the like. be registered.

For example, a record including an evaluation ID, an asset ID of an evaluation target asset, an index ID of a target evaluation index, a calculated asset evaluation value, and the like is added to the asset evaluation information 910 of the index value management DB 213. Further, in the inter-asset relationship information 920, a record including an evaluation ID, an index ID of a target evaluation index, a related asset ID which is an asset ID of an affected asset, an impact degree thereof, and the like is registered.

As a result, when the symbol 1102 (corresponding to the asset ID "00001") on the information display screen 226 is selected, for example, as shown in FIG. 19, the asset evaluation values of "welfare power" and "customer attraction power" are set. It is displayed by the balloon 1103. Further, when the "customer attracting power" in the balloon 1103 is selected, the symbols 1104-1108 corresponding to the affected assets that have influenced the "customer attracting power" of the evaluation target asset and their influence degrees 1109 and 1110 are displayed. , The symbol corresponding to the affected asset affected by the evaluated asset and its degree of influence may be displayed.

FIG. 20 is a diagram showing an example of a measure evaluation screen which is a display screen displayed in step S506 of the measure evaluation process of FIG. In the measure evaluation screen shown in FIG. 20, "measure evaluation" is selected on the menu selection screen 224. FIG. 20 illustrates a measure evaluation screen in the case of performing the first measure evaluation value calculation process for calculating the measure evaluation value of the measure target asset.

For example, in the case of a measure for adding an asset, the place to add the asset is specified by the symbol 1202, and when attribute information such as the type "medical facility" and the scale (number of beds, etc.) of the asset to be added is input, step S601. From 603, the asset evaluation value of the measure target asset, which is the asset to be added, is calculated. For example, the asset ID "9005" of the measure target asset is given, and the evaluation index "welfare power" is based on the position (latitude / longitude information) and attribute information of the symbol 1202 corresponding to the type "medical facility" and the measure target asset. The asset valuation value is calculated.

Subsequently, in step S604, from the impact management information 950 of the evaluation index management DB 214 of FIG. 16, a record corresponding to the type “medical facility” of the measure target asset and corresponding to the index ID “00001” of the evaluation target index is obtained. It is extracted, and the type and asset ID of the affected asset and the affected asset are extracted from the field 952 of the record. For example, when the record 984 is extracted, an asset whose distance from the measure target asset is within a predetermined distance and whose type is "apartment house" is specified as an affected asset. Then, the impact asset evaluation value of the impact asset after the measure (after the addition of the measure target asset) is calculated, and the impact before the measure (before the addition of the measure target asset) registered in the impact asset evaluation value and the evaluation value management DB 213. The difference from the asset evaluation value of the asset is calculated. For example, the asset evaluation value "26.84" of the welfare power before the measure of the symbol 1204 (asset ID "00002)" is acquired from the record 973 of the asset evaluation value information 910 of the index value management DB 213, and the asset evaluation value "26" is acquired. The difference 1205 between ".84" and the asset evaluation value calculated this time is displayed.

Subsequently, in step S605, the area evaluation value after the measure is calculated, and the difference between the area evaluation value and the area evaluation value before the measure registered in the evaluation value management DB 213 is calculated. For example, for the area (area ID “00001”) including the measure target asset represented by the symbol 1202, the area evaluation value of the index ID “00001” and the index name “welfare power” is calculated. When the area evaluation value is "197.76", the area evaluation value "175.98" of the welfare power of the area before the measure is acquired from the record 977 of the area evaluation information 930 of the evaluation value management DB 213, and the difference between them. 1206 is calculated and displayed as "21.78".

Subsequently, in step S606, the measure information is registered in the measure management DB 215. For example, a record 991 having a measure ID "10001", a measure type "newly established", an asset ID "9005", and the like is registered in the measure management DB 215. Further, as the evaluation information indicating the evaluation result of the measure, the calculated asset evaluation value and each difference are registered in the evaluation value management DB 213 as records 972 and 978, for example.

FIG. 21 is a diagram showing an example of a measure evaluation screen which is a display screen displayed in step S506 of the measure evaluation process of FIG. In the measure evaluation screen shown in FIG. 21, "measure evaluation" is selected on the menu selection screen 224. FIG. 21 illustrates an example of a measure evaluation screen in the case of performing a second measure evaluation value calculation process for selecting a recommended measure target asset.

For example, the target value of the area evaluation value of "welfare power" in the area of area ID "00001" is set to "195.00", and attribute information such as the type "medical facility" and scale of the added asset, and It is assumed that a candidate site for a new asset location (for example, the positions of symbols 1211, 1212 and 1213) is specified. In this case, in step S605B, the area evaluation value when the above-mentioned designated asset is added to each candidate site is calculated. For example, the welfare power when newly installed in the symbols 1211, 1212 and 1213 is "197.76", "188.25", "189.16"), respectively.

Subsequently, in step S609, among the area evaluation values calculated in step S605B, for example, the type corresponding to the evaluation value "197.76" exceeding the target value "195.00" (or closest to the target value). And the asset corresponding to the position is presented as the recommended measure target asset.

FIG. 22 is a diagram showing an example of an area evaluation screen which is a display screen displayed in step S706 of the measure evaluation process of FIG. 8 for displaying the area evaluation information. In the area evaluation screen shown in FIG. 22, "area evaluation" is selected on the menu selection screen 224.

In the example of FIG. 22, the area 1302 is designated as the evaluation target area within a radius of 1 km from the predetermined point on the map displayed on the information input screen 225. In this case, in step S801, the target area evaluation index is set based on the evaluation index information registered in the evaluation index management DB 214. For example, "area welfare ability" is set as the target area evaluation index from the record 983 of the evaluation index information 940 of the evaluation index management DB 214.

Subsequently, in step S802, the evaluation calculation formula corresponding to the evaluation formula ID "00100" of the record 983 of the evaluation index information 940 of the evaluation index management DB 214 of FIG. 16 is targeted for the target area evaluation index "area welfare ability". Specified as an area evaluation formula.

Subsequently, in step S803, the calculation target types “medical facility” and “elderly facility” of the record 983 are specified with respect to the target area evaluation index “area welfare ability” set in step S601, and the asset management DB 207 Based on the latitude / longitude information and the type, the assets of the types "medical facility" and "elderly facility" in the evaluation target area are specified as area influence assets. For example, the assets corresponding to symbols 1303 to 1307 are specified as area influence assets.

Subsequently, in step S804, the area evaluation value of the evaluation target area is calculated based on the target area evaluation calculation formula and the asset data and attribute data of the area influence asset.

Subsequently, in step S805, the area ID of the evaluation target area (for example, "00001), the target area evaluation index, the area evaluation value, the asset ID of the area influence asset, and the degree of influence are set as, for example, records 976 and 977. It is registered in the evaluation value management DB 213.

When the target value of the area evaluation value is set, in step S606, the difference between the calculated area evaluation value "175.98" and the target value is calculated. At this time, it may be possible to estimate and display which type of asset is lacking and how much from the difference value or the difference from the target area.
