Embodiments of the present invention will be described below with reference to the drawings. However, the present invention should not be construed as being limited to the contents described in the Examples shown below. Those skilled in the art will readily understand that the specific configuration can be changed without departing from the spirit or spirit of the present invention.

In the configuration of the invention described below, the same or similar configurations or functions are denoted by the same reference numerals, and redundant explanations will be omitted.

In this specification, etc., expressions such as "first," "second," and "third" are used to identify constituent elements, and do not necessarily limit the number or order.

The position, size, shape, range, etc. of each component shown in the drawings etc. may not represent the actual position, size, shape, range, etc. in order to facilitate understanding of the invention. Therefore, the present invention is not limited to the position, size, shape, range, etc. disclosed in the drawings and the like.

In Example 1, a plan is created to conduct external inspections as a preventive maintenance operation that uses resources to check the status of equipment managed by wide-area infrastructure providers such as electricity, gas, water, roads, and communications. Explain the planning system. Here, a patrol of power distribution equipment managed by a power transmission and distribution company will be explained as an example. The power distribution equipment is, for example, a telephone pole or the like.

Risk values are set for power distribution equipment, which indicate the degree of deterioration and the likelihood of accidents occurring. In the planning system, internal resources held by power transmission and distribution companies and external resources held by providers other than power transmission and distribution companies are registered as resources used for patrols. Resources are managed along with information regarding patrol quality and cost.

In addition, external resource providers include outsourced companies that conduct patrol services, companies that collect images of power distribution equipment using drones, and companies that perform delivery services using vehicles equipped with cameras, etc. These include business operators who collect images of equipment, and general residents who use smartphones to take images of power distribution equipment.

A person in charge of a power transmission and distribution company requests the planning system to formulate a patrol plan for power distribution equipment. The planning system identifies resources that can be allocated based on the risk value of the power distribution equipment, and determines the allocation of resources to the power distribution equipment and the order in which the resources in charge patrol the power distribution equipment so as to reduce the cost of patrolling. Develop a patrol plan based on this information.

The planning system sends a request to an external resource provider based on the created patrol plan. The planning system receives a response from an external resource provider as to whether or not the request can be accommodated. If there is an external resource that cannot be handled, the planning system creates a patrol plan again in which the external resource is replaced with another resource.

It is assumed that patrol data is acquired as a result of patrolling power distribution equipment using resources based on the patrol plan. The patrol data is, for example, an image of power distribution equipment.

For example, in the first entry, the power distribution equipment with the equipment ID "P001" has the patrol response period set as "2018/4/1-2018/9/30" and uses the external resource with the resource ID "OR0002". This indicates that the patrol was conducted on "2018/5/21" and the image "20180521_P001_01.jpg" was acquired as the patrol data. It also indicates that the judge "IR002" confirmed the state of the power distribution equipment using the image and determined that there was no abnormality. During the actual patrol, a resident near the installation location of the power distribution equipment with equipment ID "P001" was photographing the power distribution equipment using a smartphone, and an employee of the power transmission and distribution company named "IR002" was observing the power distribution equipment. This shows that the state of the power distribution equipment is determined using the image "20180521_P001_01.jpg" without going to the installation location.

The third entry indicates that employee "IR003" of the power transmission and distribution company moved to the installation location of the power distribution equipment with equipment ID "P003", conducted a patrol, and determined the status of the power distribution equipment on the spot. .

In this way, when employees of power transmission and distribution companies conduct patrols as internal resources, they judge the status of power distribution equipment on the spot, and when they conduct patrols using external resources, employees Collects patrol data acquired by the operator, and uses the patrol data to determine the status of the power distribution equipment. Note that the state of the power distribution equipment may be determined using image recognition technology, AI (Artificial Intelligence), or the like instead of humans.

FIG. 9 is a diagram illustrating a configuration example of the payment history information 128 according to the first embodiment.

The payment record information 128 is information for managing the payment record of remuneration to a consignee for patrol using external resources.

Payment record information 128 stores entries (payment record data) including payment date 901, resource ID 902, number of equipment 903, and payment amount 904. There is one entry for one payment. Note that the fields included in the entry are not limited to those described above. It may not include any of the fields described above, or it may include other fields.

Payment date 901 is a field that stores the date and time when remuneration was paid. Resource ID 902 is a field that stores identification information of an external resource. The number of facilities 903 is a field that stores the number of power distribution facilities inspected using external resources. The payment amount 904 is a field that stores the paid remuneration amount. The remuneration amount is calculated based on the value of unit price 405 and the value of number of equipment 903.

Next, specific processing of the planning system will be explained using FIGS. 10 to 23.

First, the resource registration process will be explained. FIG. 10 is a diagram showing an example of a screen presented by the planning device 100 of the first embodiment.

A person in charge of the power transmission and distribution company accesses the planning device 100 using the terminal 140, or an external resource provider accesses the planning device 100 using the terminal 150, and registers a user account, that is, registers the resource. I do.

When the account management unit 111 of the planning device 100 receives a resource registration request from the terminal 150, it presents a user account registration screen via the information presentation unit 114.

Here, the user account registration screen 1000 displayed on the terminal 150 will be described. The user account registration screen 1000 includes input fields 1001, 1002, 1003, 1004, 1005, 1006, 1007, a register button 1008, and a cancel button 1009. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

Input field 1001 is a field for entering an e-mail address as an ID, input field 1002 is a field for entering a password, input field 1003 is a field for entering the name of an external resource provider, and input field 1004 is a field for entering an external resource provider's name. This is a field for inputting the resource location, input field 1005 is a field for inputting information acquisition means possessed by external resources, input field 1006 is a field for inputting entrusted capacity, and input field 1007 is a field for inputting account information. This is a field for input. In the input field 1005, the name of the information acquisition means is displayed as a pull-down menu.

The registration button 1008 is an operation button for outputting an external resource registration request. A cancel button 1009 is an operation button for canceling the registration of an external resource.

The above is the explanation of the user account registration screen 1000.

The external resource provider sets values in the input fields 1001, 1002, 1003, 1004, 1005, 1006, and 1007, and operates the registration button 1008. The terminal 150 transmits a registration request including the values input in the input fields 1001, 1002, 1003, 1004, 1005, 1006, and 1007 to the planning device 100. The account management unit 111 generates identification information of an external resource, adds an entry to the external resource information 125, and sets the identification information to the resource ID 601 of the added entry. The account management unit 111 also sets the values included in the registration request in each field of the added entry.

The above is the explanation of the resource registration process.

Next, the planning process of this embodiment will be explained. FIG. 11 is a flowchart illustrating an example of a planning process executed by the planning device 100 of the first embodiment. 12, FIG. 13, FIG. 14A, and FIG. 14B are diagrams showing examples of screens presented by the planning device 100 of the first embodiment.

First, the flow of planning processing will be explained. When the planning device 100 receives a planning request from a terminal 140 operated by a person in charge of a power transmission and distribution company, the planning device 100 determines the allocation of the resource in charge to the target power distribution equipment group and the order in which the power distribution equipment is patrolled by the resource in charge. Generate a patrol plan. The planning device 100 transmits a request to a terminal 150 operated by an external resource provider, and receives a response indicating whether or not the external resource is available. The planning device 100 presents the patrol plan and response to the terminal 140. The person in charge refers to the response and, if there is an external resource that cannot be handled, sends a re-planning request to the planning device 100. The planning device 100 replaces the inapplicable external resources with other resources and generates the patrol plan again.

Below, specific contents of the processing executed by the planning device 100 will be explained.

First, a person in charge of the power transmission and distribution company uses the terminal 140 to send a request to start planning. When the information presentation unit 114 of the planning device 100 receives the planning start request, it presents the planning screen 1200 (step S1101).

Here, the planning screen 1200 will be explained. The planning screen 1200 includes an input field 1201, an extract button 1202, a power distribution equipment display field 1203, a resource display field 1204, an update button 1205, a plan button 1206, and a map display field 1207. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

The input field 1201 is a field for inputting the patrol year (year and period). The extraction button 1202 is an operation button for transmitting an extraction request. When the extraction button 1202 is operated, the terminal 140 transmits an extraction request including the patrol year input in the input field 1201 to the planning device 100. The power distribution equipment display field 1203 is a field that displays power distribution equipment to be inspected.

The resource display column 1204 is a column that displays available resources. The update button 1205 is an operation button for updating the display in the resource display field 1204. When the update button 1205 is operated, the terminal 140 transmits an update request to the planning device 100.

The planning button 1206 is an operation button for transmitting a planning request. When the planning button 1206 is operated, the terminal 140 transmits a planning request to the planning device 100.

The map display column 1207 is a column that displays a map of the area where the power distribution equipment is located. In addition to power distribution equipment, available resources are also displayed in the map display field 1207. Icon 1211 represents power distribution equipment, and icons 1212 and 1213 represent resources.

The above is the explanation of the planning screen 1200. Returning to the explanation of FIG. 11.

When the planning device 100 receives an extraction request including the year of inspection, the planning device 100 extracts the power distribution equipment to be inspected (step S1102).

Specifically, the information acquisition means setting unit 112 refers to the equipment information 121, extracts an entry in which the year obtained by adding the patrol interval 203 to the previous patrol year 207 matches the specified patrol year, and selects the entry. Store it in the work area as a power distribution equipment list. For example, if the specified patrol year is the first half of 2020, an entry is extracted in which the year obtained by adding the patrol interval 203 to the previous patrol year 207 is the first half of 2020. The information presentation unit 114 displays the power distribution equipment list in the power distribution equipment display column 1203.

When the planning request is received, the planning device 100 executes a candidate resource setting process to identify a resource having an information acquisition means that satisfies the quality of patrol according to the risk value of the extracted power distribution equipment (step S1103). ), and then executes patrol plan generation processing (step S1104). Details of the candidate resource setting process will be explained using FIGS. 15 and 16. Details of the patrol plan generation process will be explained using FIGS. 17, 18, and 19.

Information presentation unit 114 of planning device 100 presents terminal 140 with patrol plan confirmation screen 1300 for confirming the patrol plan.

Here, the patrol plan confirmation screen 1300 will be explained. The patrol plan confirmation screen 1300 includes an initial plan display field 1301, a matching rate display field 1302, a final plan display field 1303, a request button 1304, a re-planning button 1305, a decision button 1306, a cancel button 1307, and a map display field 1308. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

The initial plan display column 1301 is a column that displays an outline of the patrol plan that was first drawn up. In step S1104, an outline of the patrol plan is displayed in the initial plan display field 1301 based on the initial plan 703 of the patrol cost information 126.

The final plan display column 1303 is a column for displaying an outline of the patrol plan that has been drawn up again. Based on the final plan 705 of the patrol cost information 126, an outline of the patrol plan is displayed in the final plan display field 1303. In step S1104, the final plan display column 1303 is blank.

The matching rate display column 1302 is a column that displays the proportion of available external resources (matching rate) among the external resources included in the patrol plan originally drawn up.

The request button 1304 is an operation button for transmitting a request to a provider of an external resource included in the initially drawn up patrol plan. When the request button 1304 is operated, the terminal 140 transmits a request transmission request to the planning device 100. Note that when the planning device 100 automatically sends a request, the tour plan confirmation screen 1300 does not need to include the request button 1304.

The replanning button 1305 is an operation button for transmitting a replanning request. When the replanning button 1305 is operated, the terminal 140 transmits a replanning request to the planning device 100.

The decision button 1306 is an operation button for adopting the drafted patrol plan. A cancel button 1307 is an operation button for canceling the creation of a patrol plan.

A map display column 1308 is a column for displaying a patrol plan. In the map display column 1308, resources, the order of patrolling the resources (patrolling route), etc. are displayed on a map on which power distribution equipment is displayed. In FIG. 13, the dotted line route represents the patrol route.

The above is the explanation of the patrol plan confirmation screen 1300. Returning to the explanation of FIG. 11.

Next, when the information presentation unit 114 of the planning device 100 receives the request transmission request, it transmits the request to the terminal 150 operated by the provider of the external resource included in the patrol plan (step S1105).

A request confirmation screen 1400 is displayed on the terminal 150 based on the request.

Here, the request confirmation screen 1400 will be explained. The request confirmation screen 1400 includes a request content display field 1401, a list display button 1402, a map display button 1403, a details display field 1404, a accept button 1405, and a cancel button 1406. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

The request content display field 1401 is a field that displays an outline of the request. The details display column 1404 is a column that displays details of the request. When either the list display button 1402 or the map display button 1403 is operated, information is displayed in the details display field 1404.

List display button 1402 is an operation button for displaying a list of power distribution facilities for which inspection has been requested. When the list display button 1402 is operated, a list as shown in FIG. 14B is displayed in the details display field 1404. The list stores entries including compatibility checkboxes, equipment IDs, and the like. The external resource provider checks the availability checkbox of the entry of the power distribution equipment that can be inspected. In this way, only a part of the requested power distribution equipment can be selected.

The map display button 1403 is an operation button for displaying a map showing the power distribution equipment for which inspection has been requested. When the map display button 1403 is operated, a map as shown in FIG. 14A is displayed in the detailed display field 1404. On the map, the power distribution equipment for which inspection has been requested is highlighted. In FIG. 14A, the power distribution equipment surrounded by a rectangle indicates the power distribution equipment that has been requested to be inspected.

The accept button 1405 is an operation button for transmitting a request accept response. When the consignment button 1405 is operated in the state of FIG. 14A, the terminal 150 transmits a consignment response to the planning device 100 to the effect that the inspection of all the requested power distribution facilities is consigned. When the entrustment button 1405 is operated in the state of FIG. 14B, the terminal 150 transmits an entrustment response to the planning device 100 to the effect that the provider is entrusted with patrolling the power distribution equipment selected by the provider. In this case, the acceptance response includes identification information of the power distribution equipment selected by the provider.

A cancel button 1406 is an operation button for transmitting a cancellation response to a request. When the cancel button 1406 is operated, the terminal 150 transmits a cancellation response to the planning device 100.

The above is the explanation of the request confirmation screen 1400. Returning to the explanation of FIG. 11.

The planning device 100 receives a response corresponding to the request (step S1106).

At this time, the planning unit 113 of the planning device 100 sets a value to the matching rate 704 of the entry corresponding to the planned patrol plan in the patrol cost information 126, based on the response received from the terminal 150. Further, the information presentation unit 114 presents the value of the matching rate 704 in the matching rate display field 1302 of the patrol plan confirmation screen 1300. After that, the planning device 100 waits for a request from the person in charge.

The person in charge determines whether or not to draw up a patrol plan again, with reference to the matching rate and the like. If the matching rate is not 100%, it is impossible to patrol all of the power distribution facilities to be patrolled, so it is necessary to formulate a patrol plan again. In this case, the person in charge operates the replanning button 1305. Further, the person in charge operates a decision button 1306 to adopt the drafted patrol plan, and operates a cancel button 1307 to discard the patrol plan.

Note that when the matching rate is 100%, the planning unit 113 may automatically determine the first patrol plan to be the final patrol plan. In this case, the planning unit 113 sets the same value as the initial plan 703 in the final plan 705 of the entry corresponding to the planned patrol plan in the patrol cost information 126. Further, the information presentation unit 114 presents the same content as the initial plan display field 1301 in the final plan display field 1303.

When the planning device 100 receives a request from the terminal 140 operated by the person in charge, it determines whether the request is a replanning request (step S1107).

If the received request is a replanning request, the planning device 100 executes a patrol plan generation process (step S1108).

The patrol plan generation process in step S1108 is similar to the patrol plan generation process in step S1104, except that incompatible external resources are replaced with other resources. For other resources in charge, the information from the previous patrol plan is used as is. This makes it possible to formulate a patrol plan quickly.

The planning unit 113 stores the outline of the newly created patrol plan in the final plan 705 of the added entry of the patrol cost information 126. Further, the information presentation unit 114 presents an outline of the drafted patrol plan in the final plan display column 1303 of the patrol plan confirmation screen 1300 displayed on the terminal 140. After that, the planning device 100 shifts to the request waiting state again.

If the received request is not a replanning request, the planning device 100 determines whether the received request is a decision request (step S1109).

If the received request is not a decision request, that is, a discard request, the planning device 100 discards the patrol plan and ends the planning process. In this case, the planning unit 113 deletes the entry corresponding to the discarded patrol plan from the patrol cost information 126.

If the received request is a decision request, the planning device 100 outputs a patrol plan (step S1110). After that, the planning process ends. For example, a patrol plan is output to the terminals 140 and 150. Further, the patrol plan may be output to internal resources and external resources via the terminal 150.

The above is the explanation of the planning process.

Next, details of the candidate resource setting process will be explained. FIG. 15 is a flowchart illustrating an example of candidate resource setting processing executed by the planning device 100 of the first embodiment. FIG. 16 is a diagram showing the flow of data processing in the candidate resource setting process executed by the planning device 100 of the first embodiment.

The information acquisition means setting unit 112 selects one power distribution facility from among the power distribution facilities extracted in step S1101 (step S1501). In the example shown in FIG. 16, power distribution equipment 1600 with equipment ID "025", location "(lat25, lng25)", and risk "10%" is selected.

Next, the information acquisition means setting unit 112 identifies an information acquisition means that satisfies the required patrol quality based on the risk value of the selected power distribution equipment (step S1502).

Specifically, the information acquisition means setting unit 112 refers to the risk range 301 of the patrol quality information 122, identifies an entry corresponding to the risk range that includes the risk value of the selected power distribution equipment, and sets the corresponding entry. The value of the information acquisition means 304 is acquired.

Since the risk value of the power distribution equipment 1600 is 10%, the second entry of the patrol quality information 122 is specified. In this case, IC002, IC003, IC004, IC005, IC006, IC007, IC008, IC009, and IC010 are acquired.

Next, the information acquisition means setting unit 112 specifies a resource having the identified information acquisition means (step S1503).

Specifically, the information acquisition means setting unit 112 refers to the information acquisition means ID 505 of the internal resource information 124 and searches for an entry in which the identification information of the information acquisition means specified in step S1502 is set. Furthermore, the information acquisition means setting unit 112 refers to the information acquisition means ID 604 of the external resource information 125 and searches for an entry in which the identification information of the information acquisition means specified in step S1502 is set.

Next, the information acquisition means setting unit 112 determines candidate resources from among the identified resources (step S1504). Specifically, the following processing is executed.

(S1504-1) The information acquisition means setting unit 112 selects one resource from the identified resources.

(S1504-2) The information acquisition means setting unit 112 calculates the distance between the power distribution equipment and the selected resource. If the selected resource is an internal resource, the distance is calculated based on the position 202 of the entry corresponding to the power distribution equipment and the base 503 of the entry corresponding to the internal resource. If the selected resource is an external resource, the distance is calculated based on the position 202 of the entry corresponding to the power distribution equipment and the base 603 of the entry corresponding to the external resource.

(S1504-3) The information acquisition means setting unit 112 determines whether the calculated distance is less than or equal to the threshold value 406 of the entry corresponding to the information acquisition means possessed by the selected resource.

(S1504-4) If the calculated distance is less than or equal to the threshold 406, the information acquisition means setting unit 112 determines the selected resource as a candidate resource. In this case, as shown in FIG. 16, the information acquisition means setting unit 112 generates information that associates the identification information of the power distribution equipment with the identification information of the resource.

(S1504-5) The information acquisition means setting unit 112 determines whether processing has been completed for all identified resources. If the processing has not been completed for all identified resources, the information acquisition means setting unit 112 returns to S1504-1. When the processing is completed for all identified resources, the information acquisition means setting unit 112 ends the processing in step S1504.

The above is the explanation of the process in step S1504.

In the example shown in FIG. 16, the distance between the external resource 1601 and the power distribution equipment 1600 identified in step S1503 is 1.5 km, which is less than or equal to the threshold value of 2.0 km for the information acquisition means ID "IC002". Therefore, external resource 1601 becomes a candidate resource. The distance between the external resource 1602 and the power distribution equipment 1600 identified in step S1503 is 2.5 km, which is greater than the threshold value of 2.0 km for the information acquisition means ID "IC002". Therefore, external resource 1602 is not a candidate resource.

Next, the information acquisition means setting unit 112 determines whether processing has been completed for all the power distribution equipment extracted in step S1101 (step S1505).

If the processing has not been completed for all the power distribution equipment extracted in step S1101, the information acquisition means setting unit 112 returns to step S1501.

When the process is completed for all the power distribution equipment extracted in step S1101, the information acquisition means setting unit 112 ends the candidate resource setting process.

The above is a detailed explanation of the candidate resource setting process.

Next, details of the patrol plan generation process will be explained. FIG. 17 is a flowchart illustrating an example of a patrol plan generation process executed by the planning device 100 of the first embodiment. 18 and 19 are diagrams showing the flow of data processing in the patrol plan generation process executed by the planning device 100 of the first embodiment.

Based on the processing results of the candidate resource setting process, the planning unit 113 determines the allocation of the resource in charge to the power distribution equipment and the order in which the resource in charge patrols the power distribution equipment (tour route) so that the total cost is minimized. First, the patrol plan generation algorithm will be explained.

The patrol plan G is expressed as a set of patrol groups g_i, as shown in equation (1). Furthermore, as shown in equation (2), the patrol group g_i is expressed as a set whose elements are a set P_i of power distribution equipment, a resource in charge res_i, and a set R_i of candidate resources. The set P_i is a set of equipment p_j indicating the inspection order of the power distribution equipment, as shown in equation (3). Set R_i is a set of individual resources res_in.

Under the above premise, generating a patrol plan that minimizes the total cost is equivalent to solving an optimization problem that minimizes the objective function shown in equation (4).

The objective function f shown in equation (4) is defined by the sum of three terms f_1, f_2, and f_3. f_1 is a term representing the cost of the entire patrol plan, and is defined, for example, as in equation (5). f_2 is a term representing a penalty cost based on the difference between the power distribution equipment patrol range required for power distribution equipment patrol and the power distribution equipment patrol range of the information acquisition means, and is defined, for example, as in equation (6). be done. f_3 is a term representing a penalty cost based on the difference between the quality of patrol data required for patrolling the power distribution equipment and the quality of the patrol data of the information acquisition means, and is defined, for example, as in equation (7). .

In Equation (5), d_i represents the travel time when the resource res_i in charge moves the power distribution equipment constituting the set P_i included in the patrol group g_i in the order of elements (the order of patrol), and t_ri represents the time required for the resource res_i in charge per power distribution equipment. u_ri represents the time required for the patrol, and u_ri represents the hourly price of the resource res_i in charge. In other words, f_1 represents the cost required for patrolling all patrol groups included in the patrol plan G. Generating a patrol plan is synonymous with determining the configuration of a patrol group that minimizes f_1 (assignment of resources in charge to power distribution equipment and order of patrol of power distribution equipment by resources in charge).

In equations (6) and (7), e_j represents the power distribution equipment patrol range required for patrol of power distribution equipment p_j, and e_ri represents the power distribution equipment patrol range of the information acquisition means possessed by the responsible resource res_i included in the patrol group g_i. It represents the patrol range, q_j represents the quality of the patrol data required for patrol of the power distribution facility p_j, and q_ri represents the quality of the patrol data of the information acquisition means possessed by the responsible resource res_i included in the patrol group g_i. The function u(x,y) is a penalty function and is defined as in equation (8).

When x>y, the value of the function u(x,y) is the difference (x-y) multiplied by the constant A; when x=y, the value of the function u(x,y) is zero, When x<y, the value of the function u(x, y) is the value obtained by multiplying the difference (y−x) by the constant B. Generally, constant A is set to be larger than constant B. This means that the greater the difference between the inputs x and y, the greater the penalty is given. A larger penalty means a larger objective function.

Therefore, the minimization of f_2 is based on the patrol range of power distribution equipment required for patrolling power distribution equipment p_j and the information acquisition means possessed by the responsible resource res_i included in the patrol group, for the set P_i included in each patrol group g_i. This means determining the resource in charge that minimizes the difference from the patrol range of the power distribution equipment. The minimization of f_3 is based on the quality of patrol data required for patrolling power distribution equipment p_j and the quality of patrol data of the information acquisition means possessed by the responsible resource res_i included in the patrol group, for set P_i included in each patrol group g_i. This means determining the resources in charge of minimizing the difference in quality.

If the patrol quality of the information acquisition means possessed by the resource in charge is low compared to the patrol quality required of the power distribution equipment, it means that a resource that does not satisfy the required patrol quality is allocated. On the other hand, if the patrol quality of the information acquisition means possessed by the resource in charge is too high compared to the patrol quality required of the power distribution equipment, it means that resources with excessive patrol quality are allocated. In either of the above cases, the efficiency of the patrol plan is poor. Ideally, the quality of patrol of the information acquisition means possessed by the resource in charge is comparable to the quality of patrol required of the power distribution equipment. Therefore, in order to incorporate the above conditions, f_2 and f_3 are included in the objective function.

As explained above, the purpose of the optimization problem of this embodiment is to find the configuration of a patrol group that minimizes the objective function defined by three terms. Constraint conditions in the optimization problem are shown in Equation (9), Equation (10), Equation (11), and Equation (12).

In equation (9), h represents the working time per day, and is, for example, 7.75 hours. Equation (9) expresses the conditions for formulating a patrol plan such that the working time of one patrol group is within a predetermined daily working time h. In equation (10), c_rm represents the entrusted capacity of resource res_m. Equation (10) expresses the conditions for formulating a patrol plan so that the amount of work of each resource is within the contracted capacity. Equation (11) shows that the set R_i of the patrol group g_i is determined by the logical product set of the set R_pj of candidate resources set for each power distribution facility p_j, and is not an empty set, that is, the resource in charge is not assigned. Represents a condition that should not occur. Equation (12) represents a condition in which the first resource res_i1 in the set R_i of patrol group g_i becomes the assigned resource res_i of patrol group g_i.

The planning device 100 stores definition information that implements the aforementioned mathematical formulas and algorithms.

The optimization problem is to find a configuration of a patrol group that satisfies the above constraints and minimizes the objective function, and is a combinatorial optimization problem. In large-scale combinatorial optimization problems, it is difficult to find exact optimal solutions in a realistic amount of time, so it is common to use, for example, an approach to obtain approximate solutions using heuristics. In FIG. 17, a processing method for generating a patrol plan using the greedy method, which is one of the heuristics, will be explained.

First, the planning unit 113 sets an initial patrol group (step S1701).

Specifically, the planning unit 113 allocates internal resources from candidate resources to each power distribution facility, and sets a patrol group consisting of one power distribution facility.

Next, the planning unit 113 calculates the value of the objective function shown in equation (4) (step S1702).

Next, the planning unit 113 integrates the plurality of patrol groups (step S1703).

18 and 19 show an image of the processing in step S1703. In this processing example, as shown in FIG. 19, a first patrol group 1911 is made up of three power distribution facilities P120, P212, and P124, and a second patrol group 1912 is made up of three power distribution facilities P004, P049, and P100. are integrated to form a third patrol group 1913 consisting of six power distribution facilities. Note that in FIG. 18, a table 1801 is data representing the first patrol group 1901, a table 1802 is data representing the second patrol group 1902, and a table 1803 is data representing the third patrol group 1903.

As shown in FIG. 18, in the first patrol group 1911, the candidate resources are OR212, OR120, OR120, IR120, and IR121, and OR212 is set as the resource in charge. Further, in the second patrol group 1912, the candidate resources are OR213, OR120, OR121, IR120, and IR123, and OR213 is set as the resource in charge. The candidate resource with the smallest objective function among the candidate resources is set as the resource in charge.

When the two groups are integrated, as shown in FIG. 19, the total travel path decreases, so the objective function decreases. The candidate resources of the third patrol group 1913 are determined by taking the logical product set of the candidate resources of the two groups. Further, as a result of comparing the amount of decrease in the objective function when each of the candidate resources is set as the power distribution equipment, the OR 120 whose objective function decreases the most is set as the resource in charge of the third patrol group.

In this way, the planning unit 113 selects and integrates the two patrol groups whose objective function decreases the most from among the plurality of patrol groups. The planning unit 113 repeats the integration of patrol groups until the objective function no longer decreases.

Next, the planning unit 113 determines whether the patrol groups have been integrated as a result of the process in step S1703 (step S1704).

If the patrol groups can be integrated, the planning unit 113 returns to step S1702.

If the patrol groups cannot be integrated, the planning unit 113 stores the set of patrol groups as a patrol plan in the work area, and ends the patrol plan generation process. Patrol plans are managed in association with the patrol year.

At this time, the planning unit 113 calculates the proportion and cost of internal resources, the proportion and cost of external resources, and the total cost based on the generated patrol plan. The planning unit 113 adds an entry to the patrol cost information 126, sets the patrol year included in the extraction request in the target period 701 of the entry, and sets the number of target facilities 702 as the number of power distribution facilities extracted in step S1101. Set. Furthermore, the planning unit 113 sets the calculation result in the initial plan 703 of the added entry.

The process flow of the patrol plan generation process executed in step S1108 is the same as the process flow described above. However, in step S1701, among the patrol groups of the initially generated patrol plan, patrol groups other than the patrol groups to which external resources that cannot be supported are allocated are directly set as initial groups. Furthermore, for a patrol group to which an incompatible external resource is assigned, the external resource is excluded from the candidate resources, and a patrol group to which another resource is assigned is set. In step S1704, after generating the patrol plan, the planning unit 113 searches the patrol cost information 126 for an entry corresponding to the patrol year, and sets the calculation result in the final plan 705 of the entry.

The above is a detailed explanation of the patrol plan generation process.

Next, processing related to the implementation of patrols and payment of remuneration will be explained.

FIG. 20 is a flowchart illustrating an example of the patrol data registration process according to the first embodiment. FIG. 21 is a diagram showing an example of a screen presented by the planning device 100 of the first embodiment.

The implementer conducts a patrol according to the presented patrol plan using either internal resources or external resources, and registers the results of the patrol. Implementers are providers of external resources, internal resources and external resources when the internal resources and external resources are people.

For example, an implementer accesses the planning device 100 using a terminal and requests input of patrol data. At this time, the information presentation unit 114 displays a patrol data registration screen 2100 on the terminal. The implementer registers the patrol data using the patrol data registration screen 2100.

Here, the patrol data registration screen 2100 will be explained. The tour data registration screen 2100 includes a tour content display field 2101, a file selection button 2102, an individual registration field 2103, and a send button 2104. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

The patrol content display column 2101 is a column that displays an overview of the requested patrol.

The file selection button 2102 is an operation button for selecting a file containing inspection data (for example, images, etc.) of a plurality of power distribution facilities. When registering the patrol data of multiple power distribution facilities at once, the operator operates the file selection button 2102 to select the file to be registered.

Note that if the image includes location information, the planning device 100 collates the corresponding power distribution equipment by referring to the equipment information 121 based on the location information, and automatically associates the equipment ID with the file. and register. Furthermore, if the name of the file is set to include the equipment ID, the planning device 100 automatically registers the equipment ID and the file in association with each other.

The individual registration field 2103 is a field for registering patrol data for each power distribution facility. A list of power distribution equipment is displayed in the individual registration field 2103. The list includes a check column, equipment ID, file name, and selection button. The implementer checks the check box of the entry of the power distribution equipment for which the patrol has been completed, and also operates the selection button to register the patrol data of the power distribution equipment.

The send button 2104 is an operation button for sending a registration request for patrol data. When the implementer operates the send button 2104, a registration request including the tour data set in the file selection button 2102 or the individual registration field 2103 is sent to the planning device 100.

The above is the explanation of the patrol data registration screen 2100.

The implementer inputs patrol data via the patrol data registration screen 2100 displayed on the terminal (step S2001), and registers the patrol data in the planning device 100 by operating the send button 2104 (step S2002). .

The performance/cost management unit 115 adds an entry using the set of equipment ID, implementation date, and resource ID as a search key to the patrol performance information 127 based on the patrol data included in the registration request. Note that the implementation date may be included as metadata of the patrol data, or may be input by providing an input field on the patrol data registration screen 2100.

FIG. 22 is a flowchart illustrating the remuneration payment process executed by the planning device 100 of the first embodiment. FIG. 23 is a diagram showing an example of a screen presented by the planning device 100 of the first embodiment.

The track record/cost management unit 115 calculates remuneration based on the patrol track record (step S2201). Specifically, the following processing is executed.

(S2201-1) The performance/cost management unit 115 presents the performance confirmation screen 2300 to the terminal 140 via the information presentation unit 114.

Here, the performance confirmation screen 2300 will be explained. The performance confirmation screen 2300 includes an input field 2301, a display button 2302, a patrol result display field 2303, a map display field 2304, an approval button 2305, and a cancel button 2306. Note that the fields and buttons displayed on the screen are merely examples, and the present invention is not limited thereto. Columns and buttons may be added as necessary.

The input field 2301 is a field for inputting the patrol year (year and period). The display button 2302 is an operation button for transmitting a display request. When the display button 2302 is operated, the terminal 140 transmits a display request including the patrol year input in the input field 2301 to the planning device 100.

The inspection result display field 2303 is a column that displays the inspection results of the power distribution equipment to be inspected. The patrol results display field 2303 displays the patrol results in a list format. The person in charge approves the patrol data by checking the checkbox for each entry in the list.

The approval button 2305 is an operation button for transmitting the inspection data approval result. When the person in charge operates the approval button 2305, the terminal 140 transmits information regarding the approved patrol results (approval result information) in the patrol result display field 2303 to the planning device 100.

The cancel button 2306 is an operation button for canceling the approval operation.

The above is the explanation of the performance confirmation screen 2300.

(S2201-2) The performance/cost management unit 115 updates the value of the completion rate 706 of the patrol cost information 126 based on the approval result information.

(S2201-3) The performance/cost management unit 115 calculates the amount of remuneration to be paid to the external resource provider based on the approval result information.

Next, the track record/cost management unit 115 executes a remuneration payment process to the external resource provider based on the transfer destination 607 of the external resource information 125 (step S2202).

The performance/cost management unit 115 adds an entry to the payment performance information 128 based on the result of the remuneration payment process.
