Description

Embodiments described herein relate generally to a recovery plan management apparatus, a recovery plan program, and a recovery plan method.

When a disaster or accident occurs, equipment failure or shortage of people occurs, which reduces the operation rate of the entire business compared to normal times. The operation rate of the entire business is the operation rate of the business with respect to the normal time, and the normal operation rate is 100%.

In recent years, the Business Continuity Plan (Business Continuity Plan) has been developed to minimize the damage caused by such a decline in the operation rate of the entire business, and to continue business functions or perform early recovery after a disaster.
Nuity Plan (hereinafter BCP) is attracting attention. As a response to BCP, it is common to assume the scale of a disaster in advance and install an emergency generator or prepare a disaster response manual accordingly to prepare for a disaster.

Many of these conventional BCPs are managed to supply electricity and water to the necessary places according to the actual damage situation and the conditions of energy, people, materials, etc. restricted by the disaster at the time of the disaster, It supports a part of the process from the occurrence of a disaster to complete recovery, and there is not so much planning for the entire recovery for effective business continuity and early recovery.

In addition, the conventional BCP is intended to respond quickly to a disaster by assuming the scale of the disaster and summarizing a guideline for the number of days required for recovery and a specific response procedure. However, since the plan is based on the assumption, it is possible that the actual situation of the disaster is different from the assumption of the damage and the recovery does not proceed as planned.

Japanese Patent Laid-Open No. 2015-111379

The problem to be solved by the embodiments of the present invention is that, in the event of a disaster, the BCP is updated in real time based on the current order of damage and restrictions of each device and the priority indicating the order of restoration determined by the sales ratio of each device. Then, it is to provide a recovery plan management device that calculates the number of days and procedures until each device is recovered.

To solve the above problem,
The recovery plan management apparatus of the embodiment includes a priority calculation unit and a recovery procedure creation unit. The priority calculation unit calculates a priority that serves as an index for determining the order in which the devices are restored based on the degree of influence that is an index indicating the influence of the device on the business. The restoration procedure creation unit creates a restoration procedure that is a procedure for restoring the devices in the order of priority.

(First embodiment)
(Constitution)
FIG. 1 shows an example of the configuration of a business establishment that includes a recovery plan management device. The recovery plan management device 1 is, for example, a server mounted on a terminal device in an office or factory, and via the internal communication network 2, the production management device 3 in the factory, production equipment 4a, 4b, 4c, external energy Information such as the operating status and the degree of failure of at least a part of the source 6, the energy network 7, and the emergency generator 8 is monitored, and a recovery plan that is a plan for recovering the equipment is managed.

The production management device 3 is a control device that controls the operation of the equipment in the factory, and can view the operation status of each equipment and the information of the recovery management device 1. Can also be given.

In the line 1 in the factory, the product 5a is produced from the production equipment 4a via the production equipment 4c. In line 2, a product 5b is produced from the production device 4b. Each device can be operated not only using the energy of the external energy source 6 obtained via the energy network 7 but also using the emergency generator 8.

FIG. 2 shows an example of the functional configuration of the recovery plan management apparatus 1 according to the first embodiment of the present invention. The recovery plan management device 1 includes an acquisition unit 11, a storage unit 12, an output unit 13, a display unit 14, a recovery time calculation unit 15, a recovery curve creation unit 16, a priority calculation unit 17, and a recovery procedure creation unit 18.

The acquisition unit 11 includes device configuration information, necessary recovery time information, device failure status information (failure status information).
For example, information input in advance and information that changes in real time are acquired. The period for acquiring information that changes in real time varies depending on the object, but is acquired, for example, once a day.

Here, the device configuration information is, for example, information such as an arrangement location of a device, a number, a name, a connection source and a connection destination, and an influence degree of the device. The degree of influence is an index of how much each device affects the operation rate or sales of the entire business. In factories, the impact is production capacity. For example,
If a piece of equipment stops operating due to a failure, the production rate of the product falls and sales decrease. Therefore, you may consider the ratio of the reduction with respect to the whole sales as the influence which each apparatus has. In other words, the sum of the influences of the devices becomes the operation rate for the devices of the entire business.

FIG. 3 shows an example of the device configuration information input screen. FIG. 3A shows target selection items. FIG. 3B is a place where device configuration information is input. FIG. 3C shows a determination button. This is a screen for selecting objects such as factories, buildings / offices, houses, hospitals, towns / regions, etc., entering device configuration information in an Excel file, and clicking OK.

Necessary recovery time information is necessary recovery time indicating how long it takes to recover from a device failure and information necessary for obtaining the required recovery time. Necessary recovery time can be calculated from the degree of disaster. When the disaster is an earthquake, for example, the necessary recovery time can be obtained from the seismic intensity of the earthquake. Information that associates the degree of disaster with the required recovery time of each device is registered in advance. The unit of the necessary recovery time may be hours, days, weeks, or months.

The device failure status information is information indicating the damage status of each device. For example, the failure rate is 0% during normal times, and the failure rate and capability reduction rate of the device compared to normal times. The equipment failure status information can also be estimated from other information indicating the extent of the disaster, such as seismic intensity information. Information necessary for estimation is registered in advance.

FIG. 4 shows an example of a failure situation and necessary recovery time estimation screen when the disaster is an earthquake. FIG.
a) is an item for selecting a device. FIG. 4B is an item for selecting the degree of disaster.
For example, seismic intensity is selected. FIG. 4C shows a button for outputting the result. After selecting a device and selecting the degree of disaster, click the result output button to output the failure rate and required recovery time.

FIG. 4D is a graph in which the degree of disaster and the failure rate of the device are registered in advance. Registered for each device. FIG. 4E is a graph in which the failure rate and the necessary recovery time are registered in advance. The necessary recovery time information in FIG. 4 is the graph of FIG. 4 (d) and FIG. 4 (e).

For example, when the seismic intensity is 6 or higher, the failure rate of the device A is 50% from FIG. Further, the necessary recovery time is 5 days from FIG.

The failure rate and the required recovery time may be registered as a graph as shown in FIG. 4 or may be registered as a table. An example in which the failure rate and the required recovery time are registered in a table is shown in FIG. FIG. 5A shows items for selecting a disaster such as an earthquake, flooding, power failure, or fire. FIG. 5B is an item for selecting the seismic intensity when the disaster is an earthquake. When the determination button in FIG. 5C is clicked, the failure rate and the required recovery time are displayed for each device as shown in the table of FIG. By selecting a device, the failure rate and required recovery time are registered. In this example, the manufacturing apparatus A is registered with a failure rate of 30% and a required recovery time of 3 days.

The device failure status information may be automatically acquired from a measuring device connected to each device, or a value determined by a person may be input. As shown in FIG. 5F, when the failure rate or necessary recovery time data is acquired, the failure rate of the manufacturing apparatus A is updated from 30% to 45% as shown in FIG. 5H. When manual input is selected in FIG. 5 (f), the failure rate and the necessary recovery time can be registered or corrected by manual input.

The storage unit 12 stores each piece of information to be acquired. Each information is, for example, device configuration information, necessary recovery time information, and device failure status information for each device. When the information is updated, the new information is also stored.

The recovery time calculation unit 15 calculates the required recovery time using the device configuration information, the required recovery time information, and the device failure status information for each device stored in the storage unit 12. The calculated required recovery time is stored in the storage unit 12.

The recovery curve creation unit 16 creates a recovery curve that indicates a state in which the operation rate that has decreased due to the disaster is recovered over time due to the recovery activity. In the recovery curve, the horizontal axis represents time, and the vertical axis represents the operation rate of the entire project. The created recovery curve is stored in the storage unit 12.

The priority calculation unit 17 includes an extraction unit 171, a group creation unit 172, and a priority calculation unit 173.
Is provided.

The extraction unit 171 extracts a device related to the influence level from each device based on the influence level among the device configuration information stored in the storage unit 12. Based on the device configuration information stored in the storage unit 12, the group creation unit 172 groups together other devices necessary for the operation of the devices extracted by the extraction unit 171. The grouped information is stored in the storage unit 12.

The priority calculation unit 173 calculates the priority of the group created by the group creation unit 172 based on the device configuration information stored in the storage unit 12. The group priority is obtained by adding the influence levels of the devices included in the group, and is an index of the order of recovery.
The group priority is stored in the storage unit 12.

The recovery procedure creation unit 18 creates a procedure for performing recovery from a device group having a high priority calculated by the priority calculation unit 173. The created procedure is stored in the storage unit 12.

  The output unit 13 outputs a recovery procedure and a recovery curve that are created.

  The display unit 14 displays the recovery procedure and the recovery curve that are created.

(Function)
The operation of the recovery plan management apparatus 1 according to the first embodiment is shown in the flowchart of FIG.

First, the acquisition unit 11 of the recovery plan management apparatus 1 acquires device configuration information, necessary recovery time information, and device failure status information registered in advance (S11). Here, the device configuration information is information such as an arrangement location of the device, a number, a name, a connection source and a connection destination, and an influence degree of the device. The required recovery time information is information necessary for obtaining the required recovery time and the required recovery time. The device failure status information is information indicating the damage status of each device such as a failure rate. Each piece of information to be acquired is stored in the storage unit 12.

Next, the acquisition unit 11 of the recovery plan management apparatus acquires current device failure status information (S12).
). The information indicating the damage status of each device included in the device failure status information is, for example, information on the failure rate of the device, and may change in real time. The period for acquiring the disaster situation is, for example, once a day. Each piece of information to be acquired is stored in the storage unit 12.

Thereafter, the priority calculation unit 17 of the recovery plan management apparatus 1 calculates the priority of each device based on the degree of influence of each device (S13). This process will be described with reference to the flowchart of FIG. The required priority is stored in the storage unit 12.

And the recovery time calculation part 15 of the recovery plan management apparatus 1 calculates the required recovery time in the case of recovering in order of priority (S14). The necessary recovery time is calculated based on, for example, the failure rate of the device and the degree of disaster. The calculated necessary recovery time is stored in the storage unit 12.

Thereafter, the recovery procedure creation unit 18 of the recovery plan management device 1 creates a recovery procedure in the case of restoring in order of priority (S15). The created recovery procedure is stored in the storage unit 12. A specific example of creating a recovery procedure will be described below with reference to FIG.

Then, the output unit 13 of the recovery plan management device 1 outputs the generated recovery procedure (S16).
). The output method and display method will be described below with reference to FIG.

The process of calculating the priority of each device in S13 will be described with reference to the process flowchart of the priority calculation unit 17 that calculates the priority shown in FIG. First, the extraction unit 1 of the priority calculation unit 17
71 extracts devices related to the degree of influence from the target devices (S131).

Thereafter, the group creation unit 172 of the priority calculation unit 17 collectively groups other devices necessary for the operation of each device based on the device configuration information stored in the storage unit 12 (S132).
. As an example of extraction and grouping of devices related to the degree of influence, a description will be given with reference to FIG. FIG.
The production device 4a is a device related to the degree of influence in order to manufacture the product 5a. At this time,
Since the energy source 6 and the energy network 7 for supplying energy to the production equipment 4a, the production management device 3 that issues an operation command, and the production equipment 4c in the previous stage are equipment groups necessary for the operation of the production equipment 4a, It becomes the same group as the device 4a. The devices in the group may be shared with other groups. For example, the energy network 7 in FIG. 1 belongs to both the group of production devices 4a and the group of production devices 4b.

And the priority calculation part 173 of the priority calculating part 17 calculates a priority based on the influence degree of each apparatus group (S133).

In this embodiment, since the goal is to quickly recover the operation rate of the entire business, the operating rate of the entire business can be recovered early by preferentially restoring the group of devices including the devices with high impact. .

ＤＯＰ：優先度
ＯＰＲ（ｉ）：機器ｉの影響度 For this reason, in this embodiment, the sum of influence levels within a group is used as the priority. For example,
In the case of the device configuration of FIG. 1, in the group of production equipment 4a, when the degree of influence also exists in the production equipment 4c, the priority of the group of production equipment 4a is the sum of the degree of influence of the production equipment 4a and 4c. . Therefore, in this embodiment, the priority is expressed in the form of the following equation (1).

DOP: Priority OPR (i): Influence degree of device i

After that, the recovery procedure creation unit 18 of the recovery plan management apparatus 1 rearranges the groups in descending order of priority, and stores information on devices belonging to each group in order, thereby creating a recovery plan (S
15).

FIG. 8 shows a simple example of a method for setting the priority of a group of devices and a method for creating a recovery procedure based on the priority related to the flowchart of FIG.

FIG. 8A shows the configuration of devices and the degree of influence of each device in an example of a method for creating a recovery procedure. The equipment includes a power source, a power transmission network, equipment A, equipment B, equipment C, and equipment D, each having an impact level of 1.
0, 0, 10, 30, 20, 30. The device configuration is such that a power transmission network is connected to the power source, devices A, B, and C are connected to the power transmission network, and device D is connected to device A.

FIG. 8B shows an example of grouping and group priority. Group 1 with power,
The priority is 10 from the influence. The device A, the power source, and the power transmission network are group 2 and the priority is 20, which is the sum of the influence levels of the devices. Similarly, group 3 for device B, power source, and power grid
And the priority is 40. Device C, power supply, and power transmission network are group 4, and the priority is 30
It is. The device D, the power source, the power transmission network, and the device A are group 5 and the priority is 50.

However, the grouping in FIG. 8B is merely an example, and does not limit how to create a group or the number of groups.

FIG. 8C shows an example of the recovery procedure. In creating a recovery procedure, devices may be duplicated between groups. Therefore, by adding a process in which device information that has already been saved in another group is not saved in the procedure, duplicate device recovery plans are eliminated.

First, in procedure 1, the device of group 5, which is the highest priority group, is restored. After that, as procedure 2, the devices of group 3, which is the next highest priority group, are restored. At that time, since the power source and the power transmission network should have been restored in step 1, they are not included in the restoration procedure.

Similarly, as the procedure 3, the device of the group 4 which is the next highest priority group is restored. At that time, since the power source and the power transmission network should have been restored in step 1, they are not included in the restoration procedure.

Similarly, the device of group 2, which is the next highest priority group, is recovered, but the device of group 2 should already be recovered and is not included in the procedure. Finally, recovery of Group 1 devices is not included in the procedure because the power supply should have already been recovered. Therefore, recovery is completed in step 3.

Finally, FIG. 9 shows an example of a method for outputting the recovery procedure created by the recovery procedure creating unit 18 at the output unit 13. One of the output methods is when the display unit 14 displays on the screen. FIG. 9A is a table showing the recovery procedure to be created. FIG. 9B is a restoration curve created by the restoration curve creation unit 16.

In the restoration procedure of FIG. 9A, the devices are displayed in order of the group with the highest priority, and the guideline of the equipment requiring repair and the working days is displayed. In FIG. 9 (b), it is displayed in the form of a recovery curve centered on the number of days since the disaster occurred and the operation rate of the entire business. It is a recovery curve in the case of recovering devices one by one in order according to the order of recovery procedures.

(effect)
According to the recovery plan management apparatus of the present embodiment, when the operation rate of the business decreases due to a disaster,
By grouping equipment and calculating priority, we can obtain the most efficient recovery work procedure to recover the operation rate, recovering the operation rate early by performing work according to the procedure,
Costs for recovery can be kept to a minimum.

Note that the configuration and operation of the business establishment including the recovery management apparatus of FIG. 1 are merely examples, and do not limit the introduction form of the recovery plan management apparatus 1 according to the present embodiment. The restoration plan management apparatus 1 can be installed not only in the factory but also in buildings, offices, offices, houses, hospitals, towns, and entire areas.

The device configuration information may be stored in advance in normal times, or may be input together with other data at the time of a disaster.

In addition, regarding the degree of influence of the equipment configuration information, in contrast to those that are indirectly related to the operation of the business, such as parts manufacturing equipment, power supplies, wiring, and toilets used for manufacturing the final product, in FIG. Although the degree of influence is 0%, the degree of influence may be assigned.

In addition, the graph which shows the relationship between the failure rate of FIG.4 (e) and required recovery time is set, without setting a restriction | limiting in the number of workers who correspond to recovery.

When the failure rate of the device is known, the necessary recovery time information may be the seismic intensity of the earthquake or the failure rate of the device. If the failure rate is known, the necessary recovery time can be obtained directly using only the graph of FIG. 3E without using the graph of FIG. 4D, and the processing process can be simplified.
Moreover, a person may judge and input the failure rate and required recovery time of an apparatus.

Further, the device failure status information and the required recovery time may be updated each time the recovery operation proceeds, and the recovery plan from the current status until the recovery is completed may be re-planned.

The acquisition unit 11, the output unit 13, and the display unit 14 include both software for acquiring, outputting, and displaying each information, and hardware for realizing them.

In addition, the method of assigning priorities of the device groups of this embodiment is merely an example, and priorities can be assigned based on other policies in addition to the expression (1).

Note that when creating a recovery plan, the recovery time data may be checked and the recovery guidelines for the group may be stored together. In addition, the recovery procedure for the devices in the same group may be determined in a detailed order, for example, the devices having an influence level may be recovered first, or may be arranged in the same row as those that work simultaneously.

In addition, in FIG.9 (b), although the recovery curve at the time of recovering an apparatus in order is shown, you may display the recovery curve at the time of recovering a some apparatus in parallel. Further, when the plan is updated, a recovery curve or the like may be stored as the previous recovery results, and the recovery curve or the like after the recovery procedure update may be displayed in parallel.

In the present embodiment, the priority calculation unit 17 calculates the priority for each group, but this priority is calculated so that there is no group having the same priority that differs between groups. However, even when there are groups having the same priority, the effect of the present invention can be realized, and all groups having the same priority are handled in the same way. In this embodiment, a group is created and priorities are assigned to each group. However, priorities may be assigned to each device. In that case, if the priorities of a plurality of devices are the same, they are handled in the same manner, and are handled in the same manner as when a group is created without grouping.

(Second Embodiment)
(Constitution)
The configuration of the recovery plan management apparatus 1 according to the second embodiment will be described with reference to FIG. The second embodiment is different from the first embodiment in that an optimization calculation unit 19 is added and the information acquired by the acquisition unit 11 is increased. Other than these, the second embodiment is the same as the first embodiment. Therefore, the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

In addition to the information acquired in the first embodiment, the acquisition unit 11 acquires worker information that is information such as the number of workers that can perform recovery work. Similarly, in addition to the information stored in the first embodiment, the storage unit 12 stores worker information that is information such as the number of workers that can perform recovery work.

The optimization calculator 19 calculates a feasible worker schedule by solving the optimization problem based on the acquired worker information. The required worker schedule is stored in the storage unit 12.

(Function)
The processing operation of the recovery plan management apparatus 1 according to the second embodiment will be described using the flowchart of FIG. The second embodiment is different from the first embodiment in that S11 is changed to S21, S
12 is changed to S22, S23 is added after S13, and S14 and S15 are deleted. Since other than these are the same as those in the first embodiment, the same portions are denoted by the same reference numerals and detailed description thereof is omitted.

First, the acquisition unit 11 of the recovery plan management apparatus 1 acquires device configuration information, necessary recovery time information, device failure status information, and worker information registered in advance (S21). Here, the worker information is information indicating the number of workers corresponding to the work. Each piece of information to be acquired is stored in the storage unit 12.

An example of the worker information is shown in FIG. For example, it is a table in which whether or not work is possible every day using a worker's attendance schedule or the like. Also, assign attributes for each worker, such as electrical work, mechanical work, and office work, and give the worker attributes and the number of workers required for each equipment that needs to be restored. good. Further, not only worker resources but also available funds and energy resources may be added to the input as constraints.

Next, the acquisition unit 11 of the recovery plan management apparatus acquires current worker information in addition to the current equipment failure status information (S22). The acquired device failure status information and worker information are stored in the storage unit 12.

After that, as in the first embodiment, the priority calculation unit 17 calculates the priority based on the influence degree of each device (S13). The process of calculating the priority is the same as that in the first embodiment, as shown in the flowchart of FIG. And the optimization calculating part 19 calculates a worker schedule in consideration of the restrictions on the number of workers (S23). At this time, the recovery procedure creation unit 18 creates a recovery procedure based on the calculated worker schedule. In addition, the recovery time calculation unit 15
Calculate the required recovery time based on the recovery procedure.

The processing operation of the optimization calculation unit 19 is shown in the flowchart of FIG. First, the work plan creation unit 19 acquires worker information, grouping information, and group priority stored in the storage unit 12 (S251). Then, the work procedure is created according to the priority of the group (S
252).

Thereafter, since the number of workers is limited, calculation is performed so that the necessary recovery time is reduced while satisfying the constraint conditions such as the number of workers, and a worker schedule is created (S253). The restriction such as the number of workers is, for example, a restriction that, on a day when there are only two workers, a recovery work that requires three workers cannot be performed.

An image diagram of the worker schedule to be created is shown in FIG. The work plan table indicates which equipment is to be restored by each worker for each time period.

Here, a specific method for creating a worker schedule will be described. In the present embodiment, a worker schedule is created by solving an optimization problem for obtaining a work plan that minimizes a necessary recovery time while satisfying a constraint condition such as the number of workers.

Ｘ_ａｌｌ：全作業員スケジュール
Ｔ_ａｌｌ：全作業員スケジュールＸ_ａｌｌに対する必要復旧時間
ｔ：災害発生からの時間
Ｘ_ｉ：時刻ｔで機器ｉの作業を行う作業員
Ｐ_ｉ：機器ｉに必要な作業員の属性制約条件
Ｘ（ｔ）：作業員数の制約条件 This optimization problem is, for example, a worker attribute constraint P _i required for each device as a constraint condition,
The number of days T required for complete recovery when there is a constraint X (t) on the maximum number of workers at time t
_It can be formulated by converting the objective function of Expression (2), the constraint condition of Expression (3), and the conversion of Expression (4), which is considered as a problem of obtaining the schedule X _all of all workers that minimizes _all . The evaluation index is the required recovery time.

X _all : All worker schedule T _all : Necessary recovery time t for _all worker schedule X _all t: Time from disaster occurrence X _i : Worker P _i who performs work on equipment i at time t: Work required for equipment i Attribute constraint condition X (t): Constraint number of workers

By solving the above optimization problem, a worker schedule that reduces the required recovery time while satisfying constraints such as the number of workers is obtained.

(effect)
According to the recovery plan management apparatus of the present embodiment, when a device failure occurs due to a disaster or the like and the operation rate of the business decreases, the recovery procedure is optimized by optimizing the recovery procedure under the constraints of workers. A recovery plan that minimizes this can be obtained. In addition, by giving detailed work instructions for each worker, it is possible to avoid confusion at the site and to perform efficient recovery work.

In addition to the search shown in this embodiment, any method such as a genetic algorithm or a neural network may be used to create a work plan table for workers. This method is only an example. The method is not limited.

In this embodiment, the priority and the group priority are only used to give an initial value for the optimization problem, and it is not always necessary to obtain the priority.

Moreover, the output part 13 may output a work procedure and a recovery curve similarly to 1st Embodiment, and may output a schedule of each worker as shown in FIG.

(Third embodiment)
(Constitution)
The configuration of the recovery plan management apparatus 1 according to the third embodiment will be described with reference to FIG. The third embodiment differs from the second embodiment in that an objective function setting unit 20 and a recovery plan selection unit 2
1 is added, and other than these are the same as those in the second embodiment, and therefore, the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

The objective function setting unit 20 sets an objective function for calculation in order to create a recovery procedure, using an index such as reducing the recovery time or reducing the recovery cost. When a plurality of indicators are set, a plurality of objective functions are also set. The objective function to be set is stored in the storage unit 12.

The plan selection unit 21 calculates an objective function in the recovery plan creation unit, and causes the user to select a recovery plan as a result. The selected recovery plan is stored in the storage unit 12.

In addition to the information acquired in the second embodiment, the acquisition unit 11 acquires information on costs related to restoration, such as repairs and worker wages. Similarly, in addition to what is stored in the second embodiment, the storage unit 12 stores recovery cost information, which is information about costs related to recovery, such as repairs and worker wages.

(Function)
The operation of the recovery plan management apparatus 1 according to the third embodiment will be described using the flowchart of FIG. The third embodiment is different from the second embodiment in that S21 is changed to S31 and S22.
Is changed to S32, S33, S34, and S35 are added after S13, and S23 is deleted. Other than these, the second embodiment is the same as the second embodiment, so the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

First, in addition to the information acquired by the acquisition unit 11 of the recovery plan management device 1 in the second embodiment, recovery work such as daily wages of workers, daily loss due to suspension of product shipment, equipment repair costs, etc. Recovery cost information indicating the cost of the cost is acquired (S31, S32).

Ｘ（ｔ）：作業員数の制約条件 Then, the objective function setting unit 20 changes the weight for the evaluation index and creates a plurality of objective functions (S33). The objective function is a multi-objective optimization problem. In this embodiment, in addition to the necessary recovery time that is the evaluation index of the second embodiment, the multi-objective optimization problem that uses the recovery cost that is the cost for recovery as an evaluation index deal with. The objective function can be expressed, for example, in the form of equation (5). Further, in order to consider the restriction on the number of workers, the equations (6) and (7) are considered.

J: Objective function Q ₁ , Q ₂ : Weight X _all : All worker schedule T _all : Necessary recovery time for _all worker schedule X _all C _all : Recovery cost for _all worker schedule X _all t: Time from disaster occurrence X _i : Worker P _i who works on the device i at the time t: Attribute constraint condition of the worker required for the device i X (t): Constraint condition of the number of workers

Then, the recovery procedure creation unit 18 calculates a recovery procedure that reduces the objective function (S34).
.

At that time, the worker schedule may be calculated in consideration of the restriction on the number of workers as in the second embodiment. That is, taking into account the restriction on the number of workers, the recovery time calculation unit 15 calculates the required recovery time based on the calculated recovery procedure.

Here, the values of the weights Q ₁ and Q ₂ for each objective in the objective function are adjusted according to the user's preference. Also, a plurality of recovery plan candidates can be given by giving a plurality of combinations of the above weights and storing each plan.

The recovery plan selection unit 21 causes the user to select a recovery plan from the plurality of recovery plan candidates (S35). An example of a recovery plan selection screen is shown in FIG. The output unit 13 outputs the selected recovery plan and recovery procedure (S16).

FIG. 17 shows a screen for displaying 1, selecting a recovery time minimum type, 2, a minimum cost type, and 3, and other recovery plans side by side. Displays the recovery curve, recovery cost, and required recovery time for each type.

For the minimum recovery time type, the recovery procedure is planned only with the evaluation index that reduces the required recovery time. In the minimum cost type, the recovery procedure is planned only by the evaluation index that reduces the recovery cost. Other recovery plans have different weight ratios of evaluation indexes that reduce the required recovery time or reduce the recovery cost. A ratio of “weight of evaluation index for reducing necessary recovery time” to “weight of evaluation index for reducing recovery cost” can be selected.

(effect)
According to the recovery plan management apparatus of the present embodiment, it is possible to create a recovery plan according to the user's preference by giving a plurality of target indexes and solving the multi-objective optimization problem and by allowing the user to select a recovery plan. .

Note that the method of providing the objective function and the method of optimization of this embodiment are merely examples, and other functions and methods can be used. In this embodiment, the recovery time and the recovery cost are used as the evaluation index, but the evaluation index is not limited to this, and in order to keep the office environment comfortable even in the event of a disaster, Comfort may be added to the indicator.

In addition, although a method for selecting a recovery plan has been described in the present embodiment, a user's preference may be input in advance and a plan corresponding to the user's preference may be output. You may adjust and re-plan.
