Description

[Technical field]

[0001] The present disclosure relates to a hazard response support system, a hazard response support method, and a hazard response support program that support responses to hazards in buildings. [Background technology]

[0002] In order to respond to emergencies such as natural disasters and system failures, business continuity plans (BCPs) are being considered in companies. In these BCPs, methods and means for minimizing damage to business assets and enabling business continuity and early recovery are determined. For this purpose, a BCP support device for determining the priority order of multiple measures has been considered (see Patent Document 1). The BCP support device described in this document individually evaluates multiple implemented measures against disasters and the like of a target building, and obtains an individual score assigned to each implemented measure. Furthermore, a corrected score is obtained by increasing or decreasing the implemented measures by taking into consideration the mutual influence of the implemented measures depending on the combination of the implemented measures. Then, the priority order of the implemented measures is determined so that the higher the score obtained by reflecting the corrected score in the individual score, the higher the priority order of the implemented measures.

[0004] The technology described in Patent Document 1 makes it possible to determine the priority order of countermeasures. However, when deciding which countermeasure to take, it is necessary to consider the balance between effectiveness and cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of a hazard response support system, a hazard response support method, and a hazard response support program will be described with reference to Figs. 1 to 4. In this embodiment, the selection of measures to respond to hazards caused by disasters and the like is supported. Here, hazards refer to potential dangers and risks caused by natural phenomena and human factors. As shown in FIG. 1, a hazard response support system A1 of this embodiment includes a user device 10 and a support server 20 that are connected to each other via a network.

[0009] (Hardware configuration description) 2, a hardware configuration of an information processing device H10 constituting the user device 10 and the support server 20 will be described. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it may be realized by other hardware.

[0010] The communication device H11 is an interface that establishes a communication path with other devices and transmits and receives data. The input device H12 is a device that accepts input of various information. The display device H13 is a display or the like that displays various information.

[0011] The storage device H14 is a storage device that stores data and various programs for executing various functions of the user device 10 and the support server 20. Examples of the storage device H14 include a ROM, a RAM, and a hard disk.

[0012] The processor H15 uses the programs and data stored in the storage device H14 to control each process in the user device 10 and the support server 20. Examples of the processor H15 include a CPU and an MPU. The processor H15 loads the programs stored in the ROM, etc., into the RAM and executes various processes for each process.

[0013] The processor H15 is not limited to a processor that performs software processing for all the processes it executes. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application specific integrated circuit (ASIC)) that performs hardware processing for at least a part of the processes it executes. That is, the processor H15 may be configured as follows:

[0014] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits that include combinations of these The processor includes a CPU and memory, such as RAM and ROM, that stores program codes or instructions configured to cause the CPU to execute processes. Memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0015] (Functions of Hazard Response Support System A1) Next, each function of the hazard response support system A1 will be described with reference to FIG. The user device 10 is a computer terminal used by a user who uses this system.

[0016] The support server 20 is a computer system that supports measures against hazards caused by disasters, etc. The support server 20 includes a control unit 21, a building information storage unit 22, a scenario storage unit 23, a measure information storage unit 24, a hazard information storage unit 25, and an evaluation result storage unit 26.

[0017] The control unit 21 performs processes (including a management stage, an analysis stage, an evaluation stage, etc.) described below. By executing a processing program for this purpose, the control unit 21 functions as a management unit 210, an analysis unit 211, an evaluation unit 212, etc.

[0018] The management unit 210 executes a process of acquiring, from the user device 10, building information, which is design information indicating the structure of the building to be evaluated. The analysis unit 211 executes a simulation process (hazard simulation) assuming a disaster. The evaluation unit 212 executes a process of outputting countermeasure candidates acquired by a hazard simulation using a hazard scenario to the user device 10. As will be described later, the evaluation unit 212 retains data on a necessity determination reference value for determining the necessity of countermeasures by comparing with a pre-countermeasure hazard coefficient in order to determine the necessity of hazard mitigation countermeasures.

[0019] The building information storage unit 22 records building information of the evaluation target. This building information is recorded when design information of the building is acquired from the user device 10. The building information is generated, for example, by BIM (Building Information Modeling). Note that the building information is not limited to information generated by BIM as long as it is information indicating the structure of the building. The building information includes a BIM model (element model, arrangement information, attribute information) for a building identifier.

[0020] The building identifier is information related to an identifier for identifying a building. The building identifier is used to associate the building with the name, address, etc. of the construction site recorded in another storage unit. An element model is information about the three-dimensional shape (three-dimensional model) of each element that constitutes a structure.

[0021] The placement information includes information about the placement (coordinates in the virtual space) of the three-dimensional model. The attribute information is the attribute information of this element (specifications, dimensions, weight, materials, equipment, etc.). This attribute information makes it possible to identify the functions of the building.

[0022] The scenario storage unit 23 records scenario information about hazards that may occur in a building. This scenario information is recorded when a hazard scenario is generated. For each hazard identifier, the scenario information records information on the classification, hazard target, required function, target equipment, base specification, occurrence event, occurrence cause, detection method, hazard severity, occurrence probability before countermeasures, and detectability before countermeasures. The hazard severity, occurrence probability before countermeasures, and detectability before countermeasures are used as hazard evaluation elements for evaluating hazards.

[0023] The hazard identifier is an identifier for identifying each hazard that may occur in a building. The category is information about the category of the hazard. For example, the category may be "air conditioning."

[0024] The hazard target is information about an object that will be affected if a hazard occurs. For example, the "health of residents" is an example of a hazard target. The required functions are information on the specifications required for the classification, such as the temperature range and humidity range within a building.

[0025] The target equipment is information about equipment that may cause a hazard. For example, the target equipment may be an "air conditioning heat source (general air conditioning equipment)." The base specifications are information about the specifications before hazard countermeasures are implemented. Here, hazard countermeasures are measures to reduce potential dangers and risks caused by natural phenomena and human factors. An example of the base specifications is "no gas cogeneration system." This gas cogeneration system is a system that effectively utilizes the heat generated during the power generation process.

[0026] An occurrence event is information about an event caused by a hazard. For example, an occurrence event may be "deterioration of the temperature environment due to the stoppage of air conditioning equipment." The occurrence cause is information about the cause of the hazard. For example, the occurrence cause may be "lightning strike."

[0027] The detection method is information about a method for detecting the occurrence of a hazard. For example, the detection method may be "detectable by central monitoring." The hazard severity is an index (score) that evaluates the magnitude of the impact of the hazard. In this embodiment, the hazard severity is calculated using information included in the building information (e.g., structure according to the building type) as a variable.

[0028] The pre-countermeasure occurrence probability is an index (score) that evaluates the probability of this hazard occurring. In this embodiment, the pre-countermeasure occurrence probability is a value calculated using information included in the building information (e.g., the area where the building is located, the structure of the building, etc.) as variables.

[0029] The detectability before countermeasures is an index (score) that evaluates the detectability of the hazard. In this embodiment, the detectability before countermeasures is a value calculated using information included in the building information (e.g., the status of monitoring equipment, etc.) as a variable.

[0030] The countermeasure information storage unit 24 records hazard countermeasure information for reducing the impact of each hazard. This hazard countermeasure information is recorded when a hazard countermeasure is considered. The hazard countermeasure information records, for each countermeasure method identifier, information on the hazard identifier, the mitigation countermeasure specification, the effect, the countermeasure severity, the occurrence probability after the countermeasure, the detectability after the countermeasure, and the initial investment.

[0031] The countermeasure method identifier is an identifier for identifying each mitigation measure for a hazard. The hazard identifier is an identifier for identifying the hazard that is the target of the mitigation measure.

[0032] The reduction specification is information about equipment to be added to the base specification. For example, there is "addition of a gas cogeneration system." The effect is the effect that is produced by adding the reduction countermeasure specifications. For example, the effect is that "power supply can be secured even in an emergency for the regular generator."

[0033] The severity of the countermeasure is an index (score) that evaluates the magnitude of the impact of the hazard when the mitigation countermeasure is implemented. The probability of occurrence after countermeasures is an index (score) that evaluates the probability of a hazard occurring when mitigation measures are taken.

[0034] Detectability after countermeasures is an index (score) that evaluates the detectability of a hazard when mitigation measures are implemented. Initial investment is information on the cost per unit area of ​​the total building area required for hazard mitigation measures.

[0035] The hazard information storage unit 25 records information on hazards that may occur in the target building. This hazard information is recorded when the support process is performed. The hazard information includes information on the hazard identifier, the severity of countermeasures, the probability of occurrence before countermeasures, the possibility of detection before countermeasures, the hazard coefficient before countermeasures, and the judgment flag.

[0036] The hazard identifier is an identifier for identifying a hazard that may occur in the building. The severity of the countermeasure is an index (score) that evaluates the magnitude of the impact of the hazard when the mitigation countermeasure is implemented.

[0037] The probability of occurrence before countermeasures is an index (score) that evaluates the probability of a hazard occurring in the building being evaluated before countermeasures are taken. Pre-countermeasure detectability is an index (score) that evaluates the detectability of a hazard in the building being evaluated before countermeasures are taken.

[0038] The pre-countermeasure hazard coefficient is an index that integrates the hazard severity, the probability of occurrence, and the possibility of detection for the building being evaluated. This pre-countermeasure hazard coefficient is calculated using a specified function with the scores of the hazard severity, the probability of occurrence, and the possibility of detection as variables. The determination flag is information indicating whether or not hazard mitigation measures are required.

[0039] The evaluation result storage unit 26 records evaluation result information of each hazard for the building to be evaluated. This evaluation result information is recorded when the support process described later is performed. The evaluation result information includes information on classification, countermeasure method identifier, initial investment, hazard reduction effect, and efficiency index.

[0040] Classification is information about the classification of a hazard. The countermeasure method identifier is an identifier for identifying a mitigation measure that can be applied to the building being evaluated. The initial investment is information regarding the cost per unit area required for the reduction measures. The hazard reduction effect is the difference between the hazard coefficient before the reduction measure (hazard coefficient before the measure) and the hazard coefficient after the reduction measure (hazard coefficient after the measure). The efficiency index is the hazard mitigation effect divided by the initial investment (BCP efficiency).

[0041] (Support processing) The support process will be described with reference to FIGS.

[0042] First, the control unit 21 of the support server 20 executes a process of acquiring building information (step S11). Specifically, the user specifies building information to be evaluated using the user device 10. In this case, the management unit 210 of the control unit 21 acquires the building information from the user device 10 and records it in the building information storage unit 22.

[0043] Next, the control unit 21 of the support server 20 sequentially identifies the hazard scenarios recorded in the scenario storage unit 23 as targets for processing, and repeats the following processing for each hazard scenario. Here, the control unit 21 of the support server 20 executes a hazard simulation process (step S12). Specifically, the analysis unit 211 of the control unit 21 checks whether the building corresponds to the base specification of the scenario information by using the building information recorded in the building information storage unit 22. If not, the process using this hazard scenario is terminated.

[0044] On the other hand, when the building corresponds to the base specification of the scenario information, the analysis unit 211 calculates a score of the hazard severity based on the occurrence event of the scenario information. For example, when the occurrence event is "deterioration of the temperature environment due to the stop of the air conditioning equipment", the analysis unit 211 calculates a score according to the type of the building. In addition, the analysis unit 211 calculates a score of the occurrence probability before countermeasures based on the occurrence factor of the scenario information. For example, when the occurrence factor is "lightning strike", the analysis unit 211 acquires the occurrence probability of "lightning strike" before countermeasures based on the construction location (area) of the building from a weather information site, and calculates a score according to the occurrence probability before countermeasures. In addition, the score of the occurrence probability of "lightning strike" before countermeasures may be calculated based on the building structure. For example, the analysis unit 211 may adjust the score of the occurrence probability before countermeasures based on the shape of the building and the presence or absence of a lightning protection structure based on the building information. In addition, the analysis unit 211 calculates a score of the detectability before countermeasures of the scenario information. For example, in the building information, the score of the detectability before countermeasures is calculated according to the status of the monitoring equipment. Next, the analysis unit 211 calculates a pre-countermeasure hazard coefficient from each score of the hazard severity, pre-countermeasure occurrence probability, and pre-countermeasure detectability of the scenario information.

[0045] Next, the control unit 21 of the support server 20 executes a hazard recording process (step S13). Specifically, the analysis unit 211 of the control unit 21 records the hazard severity, pre-countermeasure occurrence probability, pre-countermeasure detectability, and pre-countermeasure hazard coefficient calculated according to the hazard scenario in the hazard information storage unit 25 in association with the hazard identifier. Then, the control unit 21 of the assistance server 20 repeats the process until all hazard scenarios recorded in the scenario storage unit 23 are used.

[0046] Next, the control unit 21 of the support server 20 executes a process for determining the necessity of hazard mitigation measures (step S14). Specifically, the evaluation unit 212 of the control unit 21 determines the necessity of hazard mitigation measures by comparing the pre-countermeasure hazard coefficient with the necessity determination reference value. Here, if the pre-countermeasure hazard coefficient is equal to or less than the necessity determination reference value, it is determined that hazard mitigation measures are unnecessary. Then, the evaluation unit 212 records a determination flag of "countermeasure required" or "countermeasure not required" in the hazard information storage unit 25 in association with the hazard identifier.

[0047] The control unit 21 of the support server 20 identifies hazards whose hazard coefficients exceed the necessity judgment reference value and which require mitigation measures. Next, the control unit 21 of the support server 20 sequentially acquires hazard countermeasure information from the countermeasure information storage unit 24 as hazard countermeasure candidates for the hazard identifiers recorded in the hazard information storage unit 25. Then, the following process is repeated for each hazard countermeasure candidate.

[0048] Here, the control unit 21 of the support server 20 executes a hazard simulation process when taking hazard countermeasures (step S15). Specifically, the analysis unit 211 of the control unit 21 uses the hazard countermeasure information recorded in the countermeasure information storage unit 24 to calculate the scores of the countermeasure severity, the occurrence probability after countermeasures, and the detectability after countermeasures. In this case, as the countermeasure severity, a value calculated using information included in the building information after countermeasures (e.g., structure according to the building type, etc.) as a variable is used. Also, as the occurrence probability after countermeasures, a value calculated using information included in the building information after countermeasures (e.g., structure of the building, etc.) as a variable is used. Also, as the detectability after countermeasures, a value calculated using information included in the building information after countermeasures (e.g., status of the monitoring equipment, etc.) as a variable is used. Then, the analysis unit 211 calculates the hazard coefficient after countermeasures from the hazard severity, occurrence probability after countermeasures, and detectability after countermeasures of the scenario information.

[0049] Next, the control unit 21 of the support server 20 executes a process of recording the hazard reduction effect (step S16). Specifically, the evaluation unit 212 of the control unit 21 calculates the hazard reduction effect by subtracting the post-countermeasure hazard coefficient calculated according to the reduction countermeasure from the pre-countermeasure hazard coefficient, and records the hazard reduction effect in the evaluation result storage unit 26 in association with the countermeasure method identifier.

[0050] Next, the control unit 21 of the support server 20 executes a process of recording the investment effect (step S17). Specifically, the evaluation unit 212 of the control unit 21 acquires the initial investment corresponding to the mitigation measure from the measure information storage unit 24. Then, the evaluation unit 212 records the initial investment in the evaluation result storage unit 26 in association with the measure method identifier. Furthermore, the evaluation unit 212 calculates an efficiency index by dividing the hazard mitigation effect by the initial investment, and records the efficiency index in the evaluation result storage unit 26 in association with the measure method identifier. Then, the control unit 21 of the support server 20 repeats the process until all hazard countermeasure candidates corresponding to the hazard scenario are completed.

[0051] Next, the control unit 21 of the support server 20 executes an output process (step S18). Specifically, the evaluation unit 212 of the control unit 21 rearranges the hazard countermeasure candidates recorded in the evaluation result storage unit 26 in descending order of efficiency index. Then, the evaluation unit 212 creates a graph that displays vectors of the initial investment (first axis) and the hazard reduction effect (second axis perpendicular to the first axis) in descending order of efficiency index. In this case, as shown in FIG. 4, a graph 500 in which mitigation measure vectors are connected in the order of hazard measures with the highest efficiency index is output to the display device H13 of the user device 10.

[0052] (Operation of the embodiment) Measures with high hazard reduction effectiveness compared to initial investment are displayed side by side.

[0053] (Effects of the embodiment) (1) In this embodiment, the control unit 21 of the support server 20 executes a hazard simulation process (step S12) and a hazard recording process (step S13). This makes it possible to evaluate possible hazards based on building information.

[0054] (2) In this embodiment, the control unit 21 of the support server 20 executes a process for determining the necessity of hazard reduction measures (step S14). This makes it possible to determine the necessity of measures based on building information.

[0055] (3) In this embodiment, the control unit 21 of the support server 20 executes a hazard simulation process (step S15) when taking hazard countermeasures and a recording process of the hazard reduction effect (step S16). This makes it possible to grasp the effect of taking mitigation measures.

[0056] (4) In this embodiment, the control unit 21 of the support server 20 executes a recording process (step S17) and an output process (step S18) of the investment effect. This makes it possible to grasp the mitigation measures that have a high mitigation effect relative to the initial investment. Furthermore, when multiple measures are taken, the overall mitigation effect can be grasped.

[0057] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. In the above embodiment, the user device 10 and the support server 20 are used, but the hardware configuration is not limited to this. For example, the user device 10 and the support server 20 may be configured as an integrated unit.

[0058] In the above embodiment, the hazard assessment factors are hazard severity, probability of occurrence before countermeasures are taken, and possibility of detection before countermeasures are taken. The hazard assessment factors are not limited to these. Some of these factors or other factors may be included.

[0059] In the above embodiment, the hazard severity, which is an index (score) that evaluates the magnitude of the hazard's impact, is calculated using information included in the building information (e.g., structure according to the building type) as a variable. Alternatively, the hazard severity score may be a constant value.

[0060] The occurrence probability before countermeasures is an index (score) that evaluates the probability of this hazard occurring. In this embodiment, the occurrence probability before countermeasures uses a value calculated using information included in the building information (e.g., area, structure, etc.) as a variable. Alternatively, the score of the occurrence probability before countermeasures may be a constant value.

[0061] The detectability before countermeasures is an index (score) that evaluates the detectability of the hazard. In this embodiment, the detectability before countermeasures uses a value calculated using information included in the building information (e.g., the status of the monitoring equipment, etc.) as a variable. Alternatively, the detectability score may be a constant value. In addition, when the scores of the hazard severity, the probability of occurrence before countermeasures, and the possibility of detection before countermeasures are set to constant values, the pre-countermeasures hazard coefficients may be registered in the scenario storage unit 23 in advance. In this case, the countermeasure severity, post-countermeasure occurrence probability, and post-countermeasure detectability recorded in the countermeasure information storage unit 24 may also be constant values.

[0062] In the above embodiment, the control unit 21 of the support server 20 executes output processing (step S18). Here, the evaluation unit 212 of the control unit 21 rearranges the hazard countermeasure candidates recorded in the evaluation result storage unit 26 in descending order of efficiency index. Here, a value obtained by dividing the hazard mitigation effect by the initial investment is used as the efficiency index. There are no limitations on the calculation method of the efficiency index as long as it is an index that can grasp the effectiveness of the hazard mitigation effect relative to the initial investment. Also, a graph in which the efficiency indexes are sorted for each classification may be generated and output. In this case, mitigation measures can be considered for each classification.

[0063] In the above embodiment, the countermeasure information storage unit 24 records hazard countermeasure information for reducing the impact of each hazard. In this hazard countermeasure information, information on initial investment is recorded for each countermeasure method identifier. Here, the countermeasure cost is not limited to the initial investment. For example, it may include running costs for a predetermined period of time.
