Description

  The present invention relates to a gas infrastructure risk management support system.

  Gas infrastructure (gas infrastructure / base) is one of the important social infrastructures for comfortable living of social life. In modern times, gas is widely and generally used as heating, cooling, power source, cooking, processing, and heat source. Therefore, the gas infrastructure is the most important social infrastructure. Therefore, the gas infrastructure needs to be constructed as a robust system and should not be vulnerable to any accident or disaster. It is an element that forms this gas infrastructure. Gas supply pipes connecting "LNG vaporizers, gas conduits, common grooves for accommodating electric wires and gas pipes, gas holders, tanks, governors, governor stations, district governors, pressure reducing valves, valves, and gas pipes for households" The connection form is called a lifeline, which is literally an important social infrastructure for life support. Therefore, large-scale monitoring systems have been proposed for monitoring LNG vaporizers (gas factories), gas high pressure conduits, gas holders, governors (pressure regulators / pressure reducers), and gas medium pressure conduits, gas low pressure conduits, etc. (For example, refer to Patent Document 1).

An occupational safety and health management system has been proposed and developed as a conventional system for managing occupational safety and health of workers who perform construction work (see, for example, Patent Document 2).
JP 2000-286988 JP 2006-59332 A

  The conventional monitoring system described above is convenient for monitoring accidents, disasters, and destruction activities that have occurred on the lifeline. However, before an accident occurs, the risk can be evaluated and estimated in advance. I can't. On the other hand, on the lifeline that forms the gas infrastructure, various works (typically maintenance work and inspection work) are carried out day and night in order to maintain and newly install gas conduits and governors that are constituent elements. ing. Since this is a work that deals with lifelines, these works are carried out by specialized engineers, and every effort is made to prevent accidents and disasters. However, the possibility that an accident will occur with a certain probability cannot be denied in any construction. In addition, since an accident / failure in gas construction occurs on a life line called a gas supply pipe (gas conduit), the life line may be cut off. Therefore, a gas supply failure represented by a gas supply stop occurs in the downstream of the lifeline that receives the gas supply through the point where the accident occurred. A gas supply failure, that is, a gas supply stoppage is a great social risk because it causes a great deal of damage to facilities, factories, ordinary households, etc. that receive gas supply from the lifeline. It would be convenient if such social risks could be predicted and understood in advance before construction work, but no such technique or system has been developed.

  In addition, the conventional occupational safety and health management system described above is a technique for evaluating occupational safety and health, that is, worker risk, of workers who perform individual construction and work. Injuries such as broken bones) and only the surrounding environment (for example, surrounding environmental damage caused by oil leakage or chemical leakage) are merely evaluated. As described above, a system for evaluating the entire work risk and evaluating a wide-area social risk resulting from the work has not been developed.

  Therefore, an object of the present invention is to provide a gas infrastructure risk management support system for obtaining a social risk caused by gas construction based on information on gas construction performed on a lifeline forming the gas infrastructure.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an outline of a gas infrastructure risk management support system according to an embodiment (Example 1) of the present invention. As shown in the figure, a gas infrastructure risk management support system (GIRM, server) 100 includes a control unit (CPU) 110, an input unit 120, an output unit 130, a communication unit 140, a storage unit 150, and a display unit. 160. The storage unit 150 includes a gas construction risk master table 152 that associates the gas construction with the risk of the point where the gas construction is performed, and at least one remote location away from the point caused by the gas construction and the gas construction. The gas construction risk link information 154 in which the risks are associated with each other is stored. The control unit 110 includes an information acquisition unit 112 and a risk calculation unit 114. The information acquisition unit 112 acquires gas construction information from another server, computer, terminal, or the like via the input unit 120 such as a keyboard or via the communication unit 140. The risk calculation unit 114 refers to the gas construction risk master table 152 and the gas construction risk link information 154 based on the gas construction information acquired by the information acquisition unit 112, and generates a social situation that occurs due to the target construction included in the gas construction information. Calculate the risk.

  Table 1 shows an example of the gas construction risk master table 152 in which the gas construction and the risk at the point where the gas construction is performed are associated with each other, and Table 2 shows the distance from the point caused by the gas construction and the gas construction. In addition, an example of the gas construction risk link information 154 in which the risk of at least one remote place (point or area) is associated is shown.

  With reference to the gas construction risk master table 152 as shown in Table 1 and the gas construction risk link information 154 as shown in Table 2, the risk calculation unit 114 of the GIRM server 100 uses the gas acquired by the information acquisition unit 112. Based on the construction information, calculate the social risk caused by the target construction included in the gas construction information.

  The communication unit 140 is connected to a network NET such as the Internet, and can send and receive data to and from remote terminals PC1, PC2, mobile terminal PDA1, mobile phone terminal MS1, etc. via the network NET. The GIRM 100 can also function as an ASP (Application Service Provider) gas infrastructure risk management support server. For example, the communication unit 140 acquires data (gas construction information such as a process management table) from the terminal PC1 via the network NET, and returns a processing result (calculated social risk) to the terminal PC1. The output unit 130 outputs various data such as the calculated social risk, the construction influence network diagram reflecting the construction risk, intermediate data generated from the system, and final data to the printer PRN, or an external display (not shown). Output).

  FIG. 2 is a flowchart showing an example of processing executed by the gas infrastructure risk management support system (GIRM) of FIG. As shown in FIG. 2, in step S <b> 11, the storage unit 150 includes a gas construction risk master table 152 that associates the gas construction and the risk at the point where the gas construction is performed, and the gas construction and the gas construction. Gas construction risk link information 154 that is associated with the risk of at least one remote location that is remote from the point that is caused is stored. Next, in step S12, the information acquisition unit 112 acquires gas construction information directly or via the input unit 120 or the like. Subsequently, in step S13, the risk calculation unit 114 refers to the gas construction risk master table 152 and the gas construction risk link information 154 based on the gas construction information acquired by the information acquisition unit 112, and is included in the gas construction information. Calculate the social risk caused by the construction.

Finally, in step S14, the display unit 160 displays the calculated social risk on the screen. The social risk can be defined as a local risk at a target construction site and a wide area (remote area) risk. For example, local risk and wide area risk are calculated using the following formula. Focusing on gas pressure or pipe diameter as a risk factor, both risks can be defined as a function of gas pressure or pipe diameter.
Local risk = construction accident possibility x construction gas pressure or pipe diameter x route non-substitution x route switching difficulty Wide area risk = local risk occurrence frequency x (WR1 + WR2 + ... WRn)
(Here, risks WR1 to n of each remote area = assumed damage x non-substitution of route x difficulty of route switching)

  FIG. 3 is a flowchart showing an example of processing executed by the gas infrastructure risk management support system (GIRM) of FIG. Steps S21 and S22 in the process of the flowchart of FIG. 3 are the same processes as steps S11 and S12 of FIG. 1, description thereof is omitted, and only other different processes are described. As shown in the figure, in step S23, the risk calculation unit 114, based on the gas construction information acquired by the information acquisition unit 112, the gas construction risk master table 152 and the “gas construction risk including gas supply pipe connection form information”. With reference to “link information” 154 (L1), the social risk generated by the target construction included in the gas construction information is calculated. Finally, in step S24, the display unit 160 displays the calculated social risk on the screen as a construction influence network diagram N1.

  The construction impact network diagram N1 highlights the points / regions related to social risks in the “gas construction risk link information including the original gas supply pipe connection type information” (in this figure, points related to social risks) / It is preferable that the area is bold and the bar portion is highlighted with a wide arrow to show the affected connection relationship. With this configuration, the point / region where the social risk occurs, the connection relationship with the site of the construction that is the root cause thereof, the geographical position, etc., become clear at a glance. That is, in this embodiment, the construction influence network diagram and the gas construction risk link information include not only the connection relationship of the gas supply pipes but also the geographical information of each point / region. In the construction influence network diagram N1 of this example, a point Y (hatched) is a point where construction is performed, and is a risk source. The points where the gas supply is received from the Y point that is the risk generation source (that is, the gas supply pipe downstream from the Y point is connected) are the Y1 to Y4 and Yn points. Since the Y1 point and the Yn point are directly supplied with gas and do not have other alternative gas supply pipes, their social risks are enormous. Since the Y2 point and the Y4 point are connected to the X1 point by the gas supply pipe, they can be replaced. However, even if substitution is possible, the degree of substitution difficulty varies depending on the ease of switching. Since the Y2 point can be easily switched by equipment such as an automatic switching device (automatic valve adjustment / opening / closing device, etc.) for the Y2 point at the X1 point, the risk at the Y2 point is reduced according to its ease. (Connection lines are shown as "dashed lines" for ease of illustration). Since the Y4 point is not equipped with the automatic switching device for the Y4 point at the X1 point, it is difficult to switch (the “connection line” is indicated by a one-dot chain line to indicate the difficulty level).

  As shown in Table 2, the gas construction risk link information includes the human risk (life risk due to gas supply stoppage, disease risk, injury, etc.) at the point where the gas construction is performed and / or in the at least one remote area / remote area. Risk, health hazard risk, emergency hospital, general hospital, impact on gas / water supply and sewerage facilities, etc., economic risk (communication facilities such as factories, offices, transportation facilities, stations, telephone stations due to gas supply stoppage) , Computer centers, network nodes, traffic lights, gas / water supply / sewerage facilities, etc. Sustained damages caused by suspension / service suspension), and security / political risks (government offices, police stations, SDF, military due to gas supply suspension) Communication facilities such as bases, telephone stations, base stations, exchanges, relay stations, computer centers, network nodes, parliament buildings, traffic lights, etc. Degree of influence) can be included.

  When referring to the gas construction risk link information shown in Table 2, the social risk calculated by this system includes the location where the target construction is carried out and / or the remote / remote area away from the location. Human risks (eg, life risks, health risks such as illness / injuries), economic risks, and security / political risks. Examples of such social risks are shown below.

  FIG. 4 is a construction influence network diagram in a form in which social risks obtained by the GIRM 100 of FIG. 1 are displayed. The construction impact network diagram is output by the output unit 130, and is printed on the printer PRN, displayed on the display unit 260, or transmitted to another computer, terminal, server, or the like via the communication unit 240. Can do. The construction influence network diagram N11 in FIG. 4 has the same gas supply pipe connection relationship as the construction influence network diagram N1 in FIG. The construction influence network diagram N11 of FIG. 4 is different from that of FIG. 3 in that the risks of each point / region are also displayed. The social risk at point Y is shown in the risk window W0. In the risk window W0, indices of human risk = 3, economic risk = 3, security / political risk = 3 are displayed. The higher the numerical value, the higher the risk, and the lower the index, the lower the risk.

  For example, human risks include the scale of hospitals, general hospitals, medical facilities, emergency hospitals, nursing homes, residences, etc. that are supplied with gas at the relevant point (region), the size of the accommodation personnel, gas / water supply / sewerage facilities, etc. It can be obtained from the type of planned gas construction. At the point, it is preferable to set the human risk index higher as the scale of the facility is larger, the number, and the number of persons accommodated are larger. That is, the human risk is a numerical value representing the life risk, illness risk, health damage risk, injury risk, emergency hospital, general hospital, power / water supply / sewerage facilities, etc. due to gas supply stoppage.

  Economic risk is due to suspension of operations / services such as communication facilities such as factories, offices, transportation facilities, stations, telephone stations, computer centers, network nodes, traffic lights, gas / water supply / sewerage facilities, etc. due to gas supply suspension This indicates the amount of damage that can be expected, and can be calculated from the number, scale, tax payment, number of employees, traffic, traffic, processing, shipping, etc. of these facilities. Security and political risks are impacts on communication facilities such as government offices, police stations, self-defense forces, military bases, telephone stations, base stations, exchanges, relay stations, computer centers, network nodes, parliament buildings, traffic signals, etc. due to gas supply interruptions The number, size, tax payment, number of employees, traffic, traffic, handling, shipping, political importance, security importance, defense importance, number of divisions of these facilities It can be calculated from the number of members, the number of policemen, the number of members of the Diet. At the point, it is preferable to set the economic risk index higher as the scale of the facility is larger and as the number of traffic, the amount of processing is larger. In districts and areas where gas supply has stopped, restaurants, restaurants, and other restaurants cannot operate, so indirectly, many facilities and institutions that do not use gas as a heat source will stop operating. It is assumed that the scale of operation will be reduced. This system can evaluate social risks that incorporate such effects.

  These numerical values indicating risk can be set from official statistical materials such as local governments, governments, and various statistical information issuing organizations. Similarly, risk windows W1 to Wn are also displayed along with Y1 to Yn which are other remote areas (regions). The total social risk window SR is obtained by tabulating and displaying the risk numerical values of these risk windows W0 to Wn. Only by looking at this comprehensive social risk window SR, it is possible to grasp the social risk on the remote area due to the gas work performed at the Y point. Note that the risk value for each window can vary depending on the type of gas construction performed at point Y.

  In each risk window, as the standard value (standard condition), set the case where the human risk exceeds 8, the economic risk exceeds 10, and the security / political risk exceeds 10. If it matches, a risk subwindow can be displayed. For example, in the risk window W3, since the economic risk is 14 and exceeds the reference value 10, the risk sub-window W31 is displayed, and the economic risk exceeds the reference value 10, and countermeasures (preventive measures) Indicates. The countermeasure here is to provide an alternative route (arrow AR) from the “X1 point” that is not affected by the Y point where the target construction is performed, and the countermeasure is shown in the risk sub-window W31. Here, the countermeasures are shown when individual risks such as economic risks exceed the standard value, but they may be implemented in the form of countermeasures when the social risk at each point exceeds the standard value. Good. As described above, if an appropriate reference value is set in advance, in this embodiment, the risk to be expected and to a risk that exceeds the reference value (matches the “reference condition” for which some countermeasures should be taken) are considered. It is possible to present countermeasures. Conventionally, experienced risk managers with advanced skills create data for risk management that has been carried out based on experience and intuition, in this embodiment, very easily and almost automatically. It becomes possible to do. Of course, reference values and reference conditions for risk management are set in advance by the risk manager, stored in the storage unit, and read and used by the system as needed. The risk calculation unit 114 performs comparison and display control between these reference values (reference conditions) and the calculated risks, but may be performed by a risk notification unit described later.

Gas construction information includes information on the gas pressure or pipe diameter of the carburetor, gas conduit, gas holder, tank, governor, governor station, pressure reducing valve, valve, or equipment that affects the gas supply. Can be made. Thus, if attention is paid to the gas pressure or the pipe diameter as a risk factor, the risk can be defined as a function of the gas pressure or the pipe diameter. The following formula is the simplest formula for determining social risk.
Social risk (wide area risk) = “Gas pressure or pipe diameter at construction site” x “Standard risk”
The formula is based on the principle that the higher the gas pressure or pipe diameter, the more gas can be supplied downstream, and there are many gas supply points and areas downstream.

Alternatively, a more accurate risk can be calculated by introducing a construction type coefficient that takes into account the standard risk of each construction as in the following equation.
Social risk (wide area risk) = "Gas pressure or pipe diameter at construction site" x "Construction type factor" x "Standard risk" x "Individual construction factor"
Here, the construction type coefficient is a coefficient set according to the construction type. It is set to “0 to 1 or about 0 to 10” according to the type of construction.

Furthermore, more accurate risk can be calculated by taking into account the standard risk at each remote location as in the following equation.
Social risk (wide area risk) = "Gas pressure or pipe diameter at construction site" x "Construction type coefficient" x "Total of standard risks WR1 to WR of each remote area that receives gas supply from construction site"
More accurate social risk can be calculated by multiplying the “accident frequency coefficient in the target construction” (however, 0 to 1) as a coefficient as shown in the following equation.
Social risk (wide area risk) = "Gas pressure or pipe diameter at construction site" x "Frequency of accidents at the target construction" x (Total of standard risks WR1 to WR of each remote area that receives gas supply from construction site) )
The risk calculation unit using any of the above formulas refers to the gas construction risk master table and the gas construction risk link information on the basis of “gas pressure or pipe diameter information”. Calculate the social risks that occur. The merit of this embodiment is that the social risk can be easily calculated by using the gas pressure or the pipe diameter information without managing complicated risk information.

  In the second embodiment, an embodiment in which information on other existing computers / systems (construction estimation server, construction progress management server, etc.) is used to obtain a social risk will be described. FIG. 5 is a block diagram showing an outline of a gas infrastructure risk management support system according to an embodiment (Example 2) of the present invention. As shown in the figure, a gas infrastructure risk management support system (GIRM, server) 200 includes a control unit (CPU) 210, an input unit 220, an output unit 230, a communication unit 240, a storage unit 250, and a display unit. 260.

The gas construction risk link information 254 in which the risks are associated with each other is stored.

  The control unit 210 includes an information acquisition unit 212, an information extraction unit 214, and a risk calculation unit 216. The information acquisition unit 212 is typically a construction estimation server CES or a construction progress management server SMS such as another server, computer, terminal, etc. via the input unit 220 or the communication unit 240 functioning as a receiving unit. To acquire / receive construction schedule information and / or construction estimate information. The communication unit 240 is connected to a network NET such as the Internet. Via the network NET, remote terminals PC1, PC2, mobile terminal PDA1, mobile phone terminal MS1, typically a construction estimation server CES and a construction progress management server SMS. It is possible to send and receive data to and from. In this embodiment, the GIRM 200 functions as an ASP (Application Service Provider) gas infrastructure risk management support server. For example, the communication unit 240 acquires data (gas construction information such as a process management table) from the construction estimation server CES and the construction progress management server SMS via the network NET.

  The construction schedule information and the construction estimation information include a detailed construction schedule, the location / point of the target construction, construction contents, personnel, unit price, and the like. The information extraction unit 214 extracts gas construction information in a format required by the present system from the construction schedule information and construction estimation information acquired by the information acquisition unit 212. The risk calculation unit 216 refers to the gas construction risk master table 252 and the gas construction risk link information 254 based on the gas construction information extracted by the information extraction unit 214, and generates a society generated by the target construction included in the gas construction information. The overall risk. The calculated risk is displayed on the screen by the display unit 260. Alternatively, the processing result (calculated social risk) may be transmitted by the communication unit (transmission unit) 240 to the terminal PC1, the construction estimation server CES, and the construction progress management server SMS.

Steps S41, S42, and S43 in the flowchart of FIG. 7 are the same as steps S11, S12, and S13 of FIG. 1, and a description thereof is omitted, and only other different processes are described. However, in step S43, the time transition of the risk is also calculated from the gas construction information (including a plurality of target constructions / construction processes and their scheduled dates and times).

  In the third embodiment, an embodiment in which the social risk is calculated using the information of the construction estimation server (integrated estimation server / system) will be described. FIG. 11 is a block diagram showing an outline of a gas infrastructure risk management support system according to an embodiment (Example 3) of the present invention. As shown in the figure, a gas infrastructure risk management support system (GIRM, server) 300 includes a control unit (CPU) 310, an input unit 320, an output unit 330, a communication unit 340, a storage unit 350, and a display unit. 360. The storage unit 350 includes a gas construction risk master table 252 that associates gas construction with the risk of the point where the gas construction is performed, and at least one remote location that is remote from the point caused by the gas construction and the gas construction. The gas construction risk link information 254 in which the risks are associated with each other is stored. The storage unit 350 further stores an integration element-risk conversion table 356 in which integration elements and risks are associated with each other.

  The control unit 310 includes an information acquisition unit 312, an information extraction unit 314, and a risk calculation unit 316. The information acquisition unit 312 can acquire the construction estimation information from the construction progress management server SMS, the construction estimation server 500, or the like via the input unit 320. Alternatively, the information acquisition unit 312 receives the construction schedule information from the construction estimation server 500 or the construction progress management server SMS, such as another server, a computer, or a terminal via the communication unit 340 functioning as a reception unit, and / or Alternatively, construction estimate information is received. The communication unit 340 is connected to a network NET such as the Internet, and via the network NET, remote terminals PC1, PC2, mobile terminal PDA1, mobile phone terminal MS1, typically a construction estimation server 500 and a construction progress management server SMS. It is possible to send and receive data to and from. In the present embodiment, the GIRM 300 will be described in the form of acquiring (receiving) estimation data including gas construction information from the construction estimation server 500 via the network NET.

  The construction estimate server (integrated estimate server, unit price type accumulated estimate server) 500 is a computer system (apparatus) having an existing general-purpose construction estimate function. Such a construction estimation server is common in the field of public works such as civil works and construction works. In particular, public works require bidding and accounting processing using estimated data based on unit price calculation based on the accumulated amount data for the walk. Since the unit price is specified in detail for each construction element (material, work process, etc.), the calculation of estimated data is complicated and complicated. It is a construction estimation server that automates this, and it is widely used in the construction industry as a representative of the public construction industry.

  In this embodiment, paying attention to the fact that such an accumulation system is often introduced in the construction industry that performs public works, it is possible to obtain social risks by using data accumulated in the accumulation estimation server / system. Can be generated automatically. Therefore, if an estimate server / system is installed at a construction company or gas company and there is necessary estimate data (construction-related data), this data is used as it is, so that social risks and environmental impacts can be avoided without human intervention. Evaluation data (environmental impact assessment, environmental impact assessment table, etc.) can be automatically created.

  Recently, unit price type bids and quotations are becoming popular under the guidance of the country, and unit price type construction estimation servers corresponding to this have been developed. In addition, a unit price type construction estimation server that can utilize the accumulated amount data has been developed and is generally used. In the present embodiment, estimate data including gas construction information is received / input from the construction estimate server 500 which is widely spread. The construction estimate server data must always be updated to the latest data for bidding and accounting necessary for the ordering / sales activities that are the core of the business, and therefore the accumulated master of the planned gas construction. Estimated data including tables and target gas construction information is always up-to-date, accurate and detailed. In other words, in this embodiment, since the gas construction information (estimation data) managed by the construction estimation server 500 as described above can be used, data is prepared for the system GIRM 300. There is a big merit that there is no need to do.

  The construction estimation server 500 includes a control unit (CPU) 510, an input unit 520, a communication unit (output unit) 540, and a storage unit 550. The control unit 510 includes an information acquisition unit 512 and an estimate calculation unit 514. The storage unit 550 stores a step master table 552. The walk master table 552 includes standard statistical information including names of a plurality of works and standard numerical values per unit quantity of each element included in each of the plurality of works. The totalization master table 554 includes customized statistical information (namely, custom data for each company) consisting of the name of the work actually received and the real value per unit quantity of each element included in the work. . The code, name, unit price, etc. of the integration elements that make up the construction are stored. The integration element can be defined at various levels. For example, the type of construction "construction type" (earthwork, construction work, electrical work, etc.), type (mechanical earthwork, equipment electrical work, wiring electrical work, etc.), standard (backhoe floor moat, high-pressure conduit laying, etc.), work process (high place) Scaffolding assembly, pressure regulator installation, switchboard installation, etc., parts / parts required for work (high pressure conduit, medium pressure conduit, gas distribution control device switchboard, governor / pressure regulator, pressure reducing valve, gas holder, tank, gas conduit, etc. ) Etc.

  It should be noted that the input format of the construction name of the target construction in the construction estimation server 500 in this embodiment is roughly divided into two construction names: a construction name in the conventional stacking method and a construction name in the unit price format. . Here, the construction name specified in the unit price format, which is the target construction, is also assumed to have the same name as the conventional stacking method. In such a case, various tables such as the walk-through master table have conventionally been used. Even those constructed with a certain accumulation method can be used without any problems. However, in order to appropriately respond to cases where the construction name differs depending on the unit definition, etc., or is more comprehensive, the "construction name conforming to the unit price type integration method" It is desirable to reset the association with each included element. Furthermore, it is preferable to provide a flag indicating that the construction price is a unit price type or a flag indicating a normal stacked type so that both types can be used together.

  The unit price type integration method does not focus on the individual elements (processes, members) included in the target construction, for example, the unit price or quantity of construction materials or fuels, so basically a step / accumulation table is created. do not have to. However, there is a need to construct a step / accumulation table for the basis for determining the unit price based on each element included in the unit and for in-house cost management. Furthermore, in order to calculate environmental impact assessment data and social risk, information on each element constructed on the walk / accumulation table is essential. Therefore, in this embodiment, the data of these elements constructed in a conventional step / accumulation table is inherited for effective use.

  The information acquisition unit 512 is an evaluation target construction (estimation target construction, which is ultimately an estimate target construction) from a terminal PC1 connected locally via the input unit 520 or the communication unit 540 or connected via a network. The name, location, and quantity of construction subject to assessment of environmental risks and environmental impacts). The estimate calculation unit 514 (breakdown data generation means) refers to the draft master table 552 stored in the storage unit 550 and determines the evaluation target construction based on the input name, location, and quantity of the evaluation target construction. Breakdown data including each element included and their quantity is generated using a computing means (MPU, CPU, etc., not shown). Furthermore, the estimate calculation unit 514 compares each element included in the construction to be evaluated with each element in the customized statistical information included in the integration master table 554, and the matching element exceeds a predetermined threshold value. Can also generate breakdown data based on the construction to be evaluated and its quantity with reference to the integration master table 554. The estimate calculation unit 514 generates estimate data for the construction to be evaluated from the number of subdivided elements (integrated elements) included in the breakdown data and statistical information (that is, unit price of the elements). The generated estimate data includes breakdown data. In general, since the unit price for payroll / accumulated data is set differently for each district, in order to calculate an accurate estimate corresponding to the place where the target construction is performed, Includes district code / location information etc. In this embodiment, the district code / location information set / described in this way is used effectively.

  The information acquisition unit 312 of the gas infrastructure risk management support system (GIRM) 300 receives / acquires estimate data from the communication unit 540 of the construction estimation server 500 via the communication unit 340 or the input unit 320. The information extraction unit 314 configures the gas construction information from the received / acquired estimated data “integration factor, quantity (set to default 1 if no quantity is displayed), and location information indicating a place where the construction is performed. Is extracted. Based on the gas construction information “cumulative element, quantity, and location information” extracted by the information extraction section 314, the risk calculation section 316 calculates the cumulative element-risk conversion table (ERT in FIG. 12) and the gas construction risk master table 252 (see FIG. 12 PRM) and gas construction risk link information 254 (PRL in FIG. 12), the social risk generated by the target construction included in the gas construction information is calculated. The calculated risk is displayed on the screen by the display unit 360. Alternatively, the processing result (calculated social risk) may be transmitted to the terminal PC 1, the construction estimation server CES, the construction progress management server SMS, and the construction estimation server 500 by the communication unit (transmission unit) 340. The function of the risk notification unit 318 is the same as the function of the risk notification unit 218. Note that functional parts having similar name names have similar functions unless otherwise noted.

FIG. 12 is a flowchart showing an example of processing executed by the gas infrastructure risk management support system (GIRM) of FIG. As shown in FIG. 12, in step S51, an integration factor-risk conversion table (ERT), a gas construction risk master table PRM, and gas construction risk link information PRL are stored. In step S52, estimate data is acquired from the construction estimate server 500. Next, in step S53, the integration element (its quantity) and location information are extracted from the estimated data. Subsequently, in step S54, the element risk is calculated with reference to the integration element-risk conversion table ERT based on the extracted integration element (the quantity). For example, when the codes indicating the extracted integrated elements are E2 and E4 and the quantity of E4 is 3, the element risk is 50 according to the following calculation formula.
ER = (E2: ER of gas high pressure conduit replacement work 20 × default quantity 1) + (E4: ER of gas high pressure conduit 100m × 3 quantity 3)
= (20 × 1) + (10 × 3) = 20 + 30
= 50

  In step S55, based on the obtained element risk and location information, the social risk generated by the target construction is calculated with reference to the gas construction risk master table (PRM) and the gas construction risk link information (PRL). The gas construction risk link information (PRL) may be a topology-type table PRL-X showing the connection state in a graphic form. The gas construction risk link information (PRL) in FIG. 12 defines points that are directly connected to one place. According to such a defining method, since the change of one place only needs to change the risk link information of the point adjacent to the point, the management becomes very simple. Of course, as shown in Table 2, a method may be used in which all locations affected by each point are described.

For example, when the obtained location information is point B and the obtained element risk is 50, the local social risk at point B is 150 according to the following calculation formula.
Social risk at point B = risk factor 3 x elemental risk 50 = 150
The wide-area social risk generated by the target construction at point B is 200 according to the following formula.
Wide area social risk = (Social risk at point B) + (Social risk at point C)
= 150 + (Social risk at point C)
= 150 + (Risk coefficient at point C 1 x elemental risk 50)
= 150 + 50
= 200

  Finally, in step S56, the calculated social risk is displayed. Estimated factor-risk conversion table (ERT) and gas construction risk master table (PRM) include human risk (HR), human risk factor (H), economic risk (ECR, E), economic risk factor ( E), Security / Political Risk (SPR), Security / Political Risk Factor (P) are defined in the Risk Breakdown and Risk Factor Breakdown. By using these breakdown figures, it is possible to determine the human risk, economic risk, and security / political risk that make up wide / local social risks. This system GIRM300 can calculate social risks as shown in Fig. 8-10 in chronological order and display them in chronological order when the estimate data includes multiple gas works and construction schedule information. It is.

  The gas infrastructure risk management support system according to the present invention can also function as an occupational health and safety evaluation system for gas work. The Occupational Health and Safety Assessment Series (OHSAS) 18001 was established by an international consortium in which organizations that have been certified on an international scale (for example, Lloyd, SGS, Japanese Standards Association) participated. Occupational safety and health management system standard. This standard is designed to check whether occupational health accident risks within organizations such as companies are minimized and activities that avoid future risks are continuously improved. OHSAS18001 consists of a plan (plan)-do (execution)-check (inspection)-action (review): planning, implementation and operation, inspection and corrective action, and management review as in the ISO14001 standard. It is composed of a so-called deming cycle, and the management system required by OHSAS 18001 requires the implementation of this cycle.

  Therefore, in order to comply with this occupational safety and health standard (pass registration and maintenance examinations), we cover all business activities, extract hazard sources in occupational safety and health, that is, risk, and calculate the impact of this. -Although it must be evaluated, whether it is manual calculation or using a computer, the current situation is that we are looking for a method that can perform quantitative processing efficiently. In such a situation, it is very difficult for companies to prepare and register their own occupational safety and health related documents. Had to be created. In addition, this standard had a maintenance review at regular intervals, and it was necessary to constantly practice the above-mentioned deming cycle and to create a hazard source (risk) evaluation table.

  By the way, in construction companies, there are many factors that affect workers and their surroundings regarding the construction work (typical ones such as falling or falling of construction workers, injury of workers due to heavy equipment for construction, etc.). Although it is necessary to create a hazard source evaluation table that takes into account the effects of each element of the above, even a single construction is composed of a number of various elements (work processes). Therefore, it has been very labor intensive and time-consuming to prepare a risk source evaluation table that appropriately evaluates the risk sources of each element of many construction works.

  The gas infrastructure risk management support system (GIRM) 100, 200, 300 according to the present invention also functions as an occupational safety and health evaluation system for gas works, and is a risk source (risk) that appropriately evaluates the risk sources of each element of the work. An evaluation table can be created. The hazard source (risk) assessment table is either fully compliant with the Occupational Safety and Health Management System OHSAS18001 depending on user requirements, construction data, integrity of the hazard source assessment master table, etc., or a hazard source that complies with this standard (Risk) Can be only part of the evaluation table. When functioning as an occupational health and safety assessment system, the hazard source assessment master table is specified as the gas construction risk master table. FIG. 13 is a diagram illustrating an example of a hazard source evaluation master table (gas construction risk master table) stored in each storage unit by the gas infrastructure risk management support system (GIRM) 100, 200, 300. As shown in the figure, the hazard source assessment master table is categorized by work process. In this figure, on the right side, work processes related to manual excavation (excavation work and inspection of workplaces) and their harmful factors (passages, rocks, etc.) ) And the associated accident type classification (stumbling, cutting, etc.). Further, in the table, the importance, occurrence possibility, evaluation (importance × occurrence possibility), and rank (for example, A is an evaluation numerical value of 70 or more, B is 50 or more, less than 70 is B, 30 or more. If it is less than 50, it is ranked on the basis of C, and if it is less than 30, it is ranked on the basis of D). By referencing such a hazard source master table, each risk calculator can identify hazard sources including “occupational health and safety risks” that constitute part of the local social risks at the site where the construction is performed. It becomes possible to evaluate. By the way, the risk (danger source / risk evaluation table) calculated is in the form of extracting a part of FIG. In the risk source / risk evaluation table of FIG. 13, it is preferable to provide countermeasures (prevention measures / prevention measures) for each risk, risk source, and operation (operation involving risk). The user can present this countermeasure to the worker, implement the countermeasure, and manage the implementation status of the countermeasure.

  The gas infrastructure risk management support system (GIRM) 100, 200, 300 according to the present invention can also function as an environmental impact assessment system for gas construction. The environmental management system is an environmental management method that has been newly defined in the international standard ISO14001 and the Japanese Industrial Standard JISQ14001, etc., and supports environmental management such as environmental audits, environmental performance evaluation, environmental labels, and life cycle assessment. It consists of standards for various methods. These are defined as management methods for management, and do not stipulate the content or level of specific measures, but are left to a considerable extent to individual business operators. The ISO14001 standard consists of a so-called deming cycle consisting of plan (plan)-do (execution)-check (inspection)-action (review): planning, implementation and operation, inspection and corrective action, and review by management. The management system required by ISO14001 requires the implementation of this cycle.

  Therefore, in order to comply with this environmental ISO (pass registration and maintenance audits), all business activities must be covered and the impact on the environment must be calculated and evaluated. Even so, the current situation is that we are exploring ways to perform quantitative processing efficiently. Under such circumstances, it is very difficult for companies to prepare their own ISO-related documents and register them. Generally, a specialized ISO consultant is asked to prepare documents for environmental assessment. There was a need. In addition, this ISO was subject to maintenance screening at regular intervals, and it was necessary to constantly practice the above-mentioned deming cycle and create an environmental impact assessment table.

  The gas infrastructure risk management support system (GIRM) 100, 200, 300 according to the present invention can also function as an environmental impact assessment system for gas construction and generate an environmental impact assessment table (data). The environmental impact assessment table (data) conforms to or complies with international standards ISO14001 and Japanese Industrial Standards JISQ14001 depending on user requirements, construction data, and the integrity of environmental master tables by resource. It can be only part of the environmental impact assessment table (data). When functioning as an environmental impact assessment system, the environmental impact assessment master table is defined as the gas construction risk master table. In that case, the environmental assessment data generation unit provided in the GIRM 100, 200, 300 refers to the resource-specific environment master table based on the construction estimate information, and environmental impact assessment data including environmental aspect data and environmental impact data. Is generated using the arithmetic means. In other words, if information that matches the information included in the construction estimate information is included in the environmental aspect data item, that item is extracted, and the environmental impact data item associated with this item is also extracted, and the environmental impact data is extracted. Data.

  For example, if the construction estimate information includes the contents shown in Table 3, search the environmental side data as shown in Table 4 using the step codes B0001 and B0002 as keys, find the ones with the same keys B0001 and B0002, and Extract environmental impact assessment data from items.

  As described above, the present systems GIRM 100, 200, and 300 can also evaluate and output the influence of the environmental aspect constituting the social risk.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the functions included in each unit, each means, each step, etc. can be rearranged so as not to be logically contradictory, and a plurality of means, steps, etc. can be combined or divided into one.
