Description

  The present invention relates to a plant construction plan support system, a construction plan support method, and a construction plan support program.

  For example, in plants such as power generation, chemistry, food, iron making, and environment, there may be occasions where work is required irregularly in addition to periodic inspections that are regularly performed. When implementing construction at the plant, laws and regulations are established from the viewpoint of industrial security, and it is necessary to formulate work plans that take into account those laws and regulations.

  For example, in the case of a power plant, it is required to formulate and comply with the safety regulations in Article 42 of the Electricity Business Law, so it is necessary to formulate a work plan that takes into account the safety management guidelines stipulated in the safety regulations.

  As a system that supports the planning of work plans such as periodic plant inspections, for example, from the viewpoint of appropriately managing the periodic inspection process at nuclear power plants, the inspection process is added or changed so that interference between inspection processes does not occur A process management system that supports this is proposed.

JP 2010-122053 A

  In the construction plan in the power plant, the execution timing of the new construction plan is examined after confirming the plant system operation process and the feasibility of the construction plan that has already been confirmed. In this study, the constraints of the plant system are also taken into consideration so as not to deviate from the safety regulations.

  For example, in a conventional plant construction planning support system such as the process management system described in Patent Document 1, it is determined whether there are devices that are to be worked on at the same time, and the inspection target is duplicated. Whether there is any interference between the fixed inspection process and the additional inspection process is determined based on the presence or absence of the device.

  In addition, for each device to be inspected, the results obtained by determining the inspection time, system isolation (isolation) time, unit test time, and test operation time of the device, and the equipment required for operating each plant system From the above information, the operation possible time, isolation time, unit test time and test operation time of each plant system are determined. Further, it is determined whether or not each plant system can be operated, isolation time, unit test time, and test operation time comply with the safety regulations.

  However, in a conventional plant construction planning support system such as Patent Document 1, it is possible to determine whether or not there is interference between a fixed (fixed) inspection process and an additional inspection process, but there is interference. If it is determined that there is, it is not possible to study and propose a plan to avoid interference on the system. Therefore, when the system determines that there is interference, there is a problem that the user needs to review the construction plan, create a new inspection process, and determine again whether there is interference.

  Also, when planning a construction plan, it is important to reliably avoid a situation in which important equipment related to system operation is damaged and troubles system operation. In order to surely avoid damage to important equipment related to system operation, it is necessary to plan in consideration of the work environment in the field as well as the time of isolation and safety regulations. In the plant construction plan support system, the work environment at the site is not taken into consideration.

  Therefore, although there are no problems with the time of isolation or safety regulations, the construction plan is approved in the state where important facilities related to grid operation are damaged depending on the work environment at the site. In some cases, construction is underway. In this case, it is necessary to suddenly review the process (so-called reverse operation) in order to avoid damage to important equipment, and the burden on not only the user but also the construction site worker is not small.

  Hereinafter, a plant construction plan support system, a construction plan support method, and a construction plan support program according to embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram schematically showing a basic configuration of a plant construction plan support system 20 which is an example of a plant construction plan support system according to an embodiment of the present invention.

  The plant construction plan support system 20 is a system for judging the necessity of reviewing a construction plan by judging a plurality of conditions in stages, and more specifically, additional work such as an unconfirmed construction plan. If the process interferes with a fixed work process, whether or not the plant operation can be continued within the scope that does not deviate from the safety regulations by utilizing the know-how accumulated in the past construction plan, that is, in the plant system of the plant After further studying whether or not the constraint conditions can be avoided, it is determined whether the construction plan needs to be reviewed.

  A fixed work process is a work process whose schedule has already been determined. Examples of the fixed work process include a work process for a construction for which a schedule has been established and a work process in accordance with a plant operation plan for which a schedule has been established.

  For example, the plant construction plan support system 20 may be configured such that the operation state of the equipment in the additional work process is the operation state of the equipment in the work process of the construction plan whose schedule is fixed (hereinafter referred to as “confirmed construction plan”). A function for performing the first determination for determining whether or not there is a contradiction, and a second for determining whether or not there is a conflict with the operation state of the device in the work process according to the operation plan of the plant for which the schedule is fixed. A function for performing the determination, a function for performing a third determination for determining the presence or absence of accumulated know-how when there is a contradiction with the operation state of the equipment in the work process according to the operation plan of the plant whose schedule is fixed, And a function of outputting the determination results of the first, second and third determinations.

  When there is accumulated know-how, the plant construction plan support system 20 uses this know-how to determine whether or not the constraint conditions of the plant system can be avoided, more specifically, whether or not the plant safety regulations can be observed. You may have the function to perform the 4th determination to determine, and the function to output the determination result of a 4th determination.

  In the plant construction plan support system 20, an area where equipment used in a work process according to a plant operation plan is used interferes with an area where equipment used in an additional work process is used within each use period. It may have a function of performing a fifth determination for determining whether or not to perform, and a function of outputting a determination result of the fifth determination. In addition, when the fifth determination is made, the importance information set for the equipment used in the work process according to the operation plan of the plant is taken into consideration, and the target for the fifth determination is important. Limited to high-level equipment, or further interference determination according to the level of importance, that is, interference determination (sixth determination) based on different criteria such as the area size is different from the fifth determination May be.

  The plant construction plan support system 20 having the functions described above includes, for example, a storage device having a processor such as a CPU (Central Processing Unit) and storage circuits such as a ROM (Read-Only Memory) and a RAM (Random-Access Memory). A computer as a hardware resource and a construction plan support program (hereinafter, the program is abbreviated as “PG” and referred to as “construction plan support PG”), which is software that realizes the above-described functions in the computer, cooperate. Is realized.

  In other words, whether the construction plan support PG can avoid the constraints in the plant system by utilizing the know-how accumulated in the past construction plan when the additional work process interferes with the fixed work process. Is a program that causes a computer to execute a processing procedure (hereinafter referred to as a “construction plan support processing procedure”) for determining whether or not a review of the construction plan is necessary and supporting the construction plan. By executing the construction plan support PG, the plant construction plan support system 20 having specific means for executing the construction plan support processing procedure in the computer is realized.

  To describe a more specific configuration example, the plant construction plan support system 20 includes, for example, an input unit 21, an output unit 22, a device state contradiction determination unit 23 (23 a, 23 b) as a determination unit, and a policy presence / absence determination. Unit 24, policy applicability determination unit 25, work area interference determination unit 26, storage unit 28, and control unit 29.

  Here, various kinds of information 31 to 38 shown in the storage unit 28 such as the temporary work plan information 31 and the finalized work plan information 32 are read out as necessary when executing the work plan support processing procedure (read). ) Or information to be written (written).

  The input unit 21 is realized by, for example, an input device connected to a computer via an interface or input means such as a keyboard or a mouse provided in the computer itself. The input unit 21 receives input of information and gives the received information to the control unit 29. The information input from the input unit 21 includes, for example, various processing execution requests, input of information such as temporary work plans, and various condition setting requests.

  The output unit 22 is realized by, for example, a display device connected to a computer via an interface or a display means such as a display provided in the computer itself, a printing means such as a printer connected to the computer via an interface, and the like. And output functions such as printing functions.

  When receiving the display request, the output unit 22 having a display function displays the content corresponding to the display request. When the output unit 22 having a print function receives a print request, the output unit 22 prints out the content corresponding to the print request.

  The appliance operating state contradiction determining unit 23 includes a first appliance operating state contradiction determining unit 23a and a second appliance operating state contradiction determining unit 23b.

  The first equipment operation state contradiction determination unit 23a refers to, for example, the temporary work plan information 31 and the finalized construction plan information 32, and the operation of the equipment when performing isolation in the added temporary (unconfirmed) construction plan. It is determined whether the state and the operation state of the device at the time of isolation in the construction plan that has already been confirmed are inconsistent or coincident (no).

  The determination (first contradiction determination) on whether or not the operation state of the device is contradictory performed by the first device operation state contradiction determination unit 23a corresponds to the first determination described above. The first device operation state contradiction determining unit 23 a outputs the determination result to the output unit 22 or stores it as determination result information 38 in the storage unit 28.

  The second equipment operation state contradiction determination unit 23b refers to, for example, the temporary work plan information 31 and the operation process information 34, and in the work process according to the operation state of the equipment in the unconfirmed construction plan and the operation plan that has already been confirmed. It is determined whether the operation state of the device is inconsistent or coincides (not).

  The determination (second contradiction determination) as to whether or not the device operation state is contradictory performed by the second device operation state contradiction determination unit 23b corresponds to the above-described second determination. The second device operating state contradiction determining unit 23 b outputs the determination result to the output unit 22 or stores it as determination result information 38 in the storage unit 28.

  Even if there is a contradiction in the operation state of the device, the policy presence / absence determination unit 24 does not affect the operation plan that has been established while complying with the safety regulations (without deviating) by taking some measures. The determination means is provided in consideration of the fact that there is a room to establish. The policy presence / absence determination unit 24 refers to the know-how information 33 to determine the presence / absence of a policy that has actually been performed in the past in the section of the plant to which the equipment in which the operation state contradiction belongs belongs. .

  The determination of the presence / absence of a policy (policy presence / absence determination) performed by the policy presence / absence determination unit 24 corresponds to the above-described third determination. The policy presence / absence determination unit 24 outputs the determination result determined for the presence / absence of the policy to the output unit 22 or saves the determination result information 38 in the storage unit 28.

  The policy applicability determination unit 25 has a function of determining whether or not the policy accepted from the policy determined by the policy presence / absence determination unit 24 can be applied without departing from the plant safety regulations. When the policy applicability determination unit 25 receives a selection from the policies determined by the policy presence / absence determination unit 24, the policy applicability determination unit 24 refers to the know-how information 33 and the safety regulation information 35 and selects within a range that does not deviate from the plant safety regulations. It is determined whether or not the policy for accepting can be applied.

  The policy applicability determination (policy applicability determination) performed by the policy applicability determination unit 25 corresponds to the above-described fourth determination. The policy applicability determination unit 25 outputs the determination result to the output unit 22 or stores it as determination result information 38 in the storage unit 28.

  The policy applicability determination may be the final determination as to whether or not the additional work process interferes with the fixed work process. In this case, the policy applicability determination unit 25 outputs a final determination result as to whether or not the additional work process interferes with the fixed work process to the output unit 22.

  The work area interference determination unit 26 determines that the work process in the unconfirmed work plan is within the work period in which the work process is performed with respect to the work process in the work plan according to the operation plan of the plant system for which the schedule has already been confirmed. Have a function of determining whether the work areas overlap (interfere).

  First, the work area interference determination unit 26 refers to the work area information 36, and the equipment used in the work process in the unconfirmed construction plan, the position of the equipment, the size of the work area, and the work period are determined based on the plant system. It is determined whether or not it interferes with the equipment used in the work process in the construction plan according to the operation plan, the position of the equipment, the size of the work area, and the work period.

  In addition, the work area interference determination unit 26 can perform determination in consideration of the importance of the equipment. In this case, the work area interference determination unit 26 changes the size (wide or narrow) of the interference prohibition area that prohibits interference or changes the number of determination steps according to the presence or absence of importance or the difference in level. judge.

  The work area interference determination (work area interference determination) performed by the work area interference determination unit 26 corresponds to the above-described fifth determination and sixth determination. The work area interference determination unit 26 outputs the determination result to the output unit 22 or stores it as determination result information 38 in the storage unit 28.

  The fifth determination and the sixth determination described above are final determinations as to whether or not the additional work process interferes with the fixed work process, and thus the determination performed by the work area interference determination unit 26. The result also includes the final determination result of whether or not the additional work process interferes with the fixed work process.

  The storage unit 28 includes a storage area where information can be read (read) and written (write), and has a function of holding information in the storage area. The storage unit 28 provides storage areas in which information can be read and written to the device operation state contradiction determination unit 23, the policy presence / absence determination unit 24, the policy applicability determination unit 25, the work area interference determination unit 26, and the control unit 29. And reading (reading) and writing (writing) information necessary to execute each process.

  When executing the construction plan support processing procedure, in the storage unit 28, for example, temporary construction plan information 31, finalized construction plan information 32, know-how information 33, operation process information 34, safety regulation information 35, work area information 36, Information including any of the important facility information 37 and the determination result information 38 is appropriately read and written. Details of each piece of information 31 to 38 will be described later.

  The control unit 29 is a processing unit that controls processing of the entire system of the plant construction plan support system 20, and includes an input unit 21, an output unit 22, an equipment state contradiction determination unit 23 (23a, 23b), a policy presence / absence determination unit 24, The policy applicability determination unit 25, the work area interference determination unit 26, and the storage unit 28 have a function of exchanging information with each other and controlling them.

  For example, when there is a display request for information from the user, the control unit 29 receives the information requested for display from the processing units 21, 23 to 26, 28 related to the information requested for display, and receives the received information. A display command to be displayed on the display unit which is an example of the output unit 22 is given. Information that has been requested to be displayed is displayed on the display unit that has received the display command.

  For example, when there is a request to display the determination result of the policy presence / absence determination by the policy presence / absence determination unit 24, the control unit 29 determines the policy presence / absence determination from the policy presence / absence determination unit 24 that performs the policy presence / absence determination for which the display request has been made. While receiving a result, the display command which displays the determination result received according to the said display request on the display part which is an example of the output part 22 is given. The determination result is displayed on the display unit according to the display command.

  The plant construction plan support system 20 only needs to include the equipment state contradiction determination unit 23 (23a, 23b) and the policy presence / absence determination unit 24 and be configured to be able to exchange information. The availability determination unit 25 and the work area interference determination unit 26 may not be provided.

For example, as shown in FIG. 5 (A), the operation process information 34 includes, as upper information, a work process such as a work process A that has been confirmed to be performed when operating a plant system. It has information indicating that more detailed processes such as A1, A2 and A3 are included. In addition, the circle mark “◯” and the cross mark “X” in FIG. 5A indicate that the process is performed and not performed, respectively.

  Further, for example, as shown in FIG. 5B, the operation process information 34 includes lower-order (more detailed) work such as process A1 included in work process A, which is a higher-order work process, as lower-order information. For each process, there is information representing the operating state of the equipment required for each equipment required for performing the subordinate work process.

  FIG. 6 is an explanatory diagram for explaining the security regulation compliance determination logic, which is an example of the security regulation information 35.

  The security regulation information 35 (FIG. 6) is used to determine whether, for example, a condition required by the security regulation for a work process such as work process A, that is, a condition for complying with the safety regulation is satisfied. It is a security regulation compliance judgment logic.

  In the plant construction plan support system 20, for example, with respect to the execution of the work process A, it is necessary to perform the determination according to the procedure (steps S1 to S4) according to the safety rule compliance determination logic shown in FIG. To determine the condition.

  The safety regulation compliance determination logic illustrated in FIG. 6 is based on the condition (i) that is required to comply with the safety regulations depending on which state of the equipment X in the plant is. This is a logic for determining which condition (iii) is satisfied.

  When the state of the equipment X (step S1) is “operation”, it becomes “condition (i)” that allows the safety regulations to be observed without performing both the process A1 and the process A2 (step S2). When the state of the equipment X (step S1) is “stopped”, if one of the steps A1 and A2 (step A1 or step A2) is performed, the safety regulations can be observed. “Condition (ii) (Step S3). When the state of the equipment X (step S1) is “others”, the “condition (iii)” (step S4) that can comply with the safety regulations can be achieved by performing both the process A1 and the process A2.

  When it is necessary to determine whether or not the safety regulations can be complied with, the plant construction plan support system 20 satisfies the conditions such as the condition (i) obtained as a result of the determination according to the safety regulations compliance determination logic. It is determined whether the safety regulations can be complied with.

  FIG. 7 (FIGS. 7A and 7B) is an explanatory diagram showing an example of the work area information 36, and FIG. 7A is an explanatory diagram showing a case where the size range is one pattern. FIG. 7B is an explanatory diagram showing a case where the size range is two patterns.

  FIG. 8 (FIG. 8A and FIG. 8B) is an explanatory diagram showing a definition example of work area position information, and FIG. 8A is a definition example for a plane (vertical direction and horizontal direction). FIG. 8B is an explanatory diagram illustrating a definition example in the height direction (Z-axis direction).

  The work area information 36 (FIG. 7) includes, for example, identification information of devices used for work, work area position information, work area size information, and work period information. The position information is defined by, for example, selecting one point (origin) in the space, setting a three-dimensional orthogonal coordinate system with the selected point as the origin, or dividing the work area into rectangular space areas, etc. By doing.

  The position information illustrated in FIGS. 8A and 8B is an example when the work area is indoors of the first building (denoted as “building # 1” in the figure). The size is defined by dividing each floor 45 (45a to 45d) of the building. In addition, regarding the position of the plane (area) of each floor, the plane area 46 of each floor is equally divided into p (p is plural) in the vertical direction (X-axis direction) and the horizontal direction (Y-axis direction), respectively. It is defined by a divided plane area 47 divided into q (q is plural).

  For example, the position indicated by the position information of the area “X2Y2” and the floor “1F”, which is an example of the position information illustrated in FIGS. 7A and 7B, is the definition of the position information illustrated in FIG. The floor 45c on the first floor (1F) of the building is the second range “X2” from the reference position (origin O) in the vertical direction and the second range “X2” from the reference position (origin O) in the horizontal direction. This is a divided plane region 47a where “Y2” intersects.

  The size information of the work area is information indicating an area that hinders self-work if the area interferes with other work. In other words, the size of the work area represents the size of the interference prohibition area. The size of the work area can be specified, for example, by setting the required length in the X-axis direction and the Y-axis direction, or by setting the center position and radius for the circular area. Defined by various information.

  The size “X1, Y1” of “device # 1” shown in FIG. 7 is a definition of the size based on the size of the divided plane area 47, and the area “X2Y2” indicating its own position is the center. The size is one for the X-axis direction and one for the Y-axis direction.

  Note that the size information included in the work area information 36 may include a plurality of size information indicating different sizes in consideration of the importance of the facility described later. For example, as shown in FIG. 7B, there are two stages of high and low importance, and different sizes may be set according to the high and low importance.

  In addition, the size information is information that directly specifies the size such as the length required in the X-axis direction and the Y-axis direction, but indirectly when there is information that indirectly specifies the size. Information defining the size may be used.

  For example, when there is information that indirectly specifies the size, for example, the size can be classified into several patterns according to the type of device. There may be a case where device management information (not shown) in association with size information representing the corresponding size is prepared. In this case, the model code associated with the size pattern is information that indirectly defines the size, and this model code can be used as the size information included in the work area information 36.

  FIG. 9 (FIGS. 9A and 9B) is an explanatory diagram showing an example of the important facility information 37. FIG. 9A shows a case where the importance is set depending on whether or not it is important. FIG. 9B is an explanatory diagram illustrating a case where importance is set by dividing a case of importance into a plurality of stages such as three stages.

  The important equipment information 37 includes, for example, importance information for identifying whether or not the equipment is the important equipment satisfying at least a predetermined importance with respect to the device identification information.

  Here, the importance level refers to a degree of importance including a case where it is not important. In the important facility information 37 illustrated in FIG. 9A, a round mark indicating that the importance is important (“◯” in FIG. 9A) and a cross mark indicating that it is not important (FIG. 9). (A) is set to “×”. Further, in the important facility information 37 illustrated in FIG. 9B, the three levels of 1 (importance: low) to 3 (importance: high) indicating the importance and the degree of importance, It is set to 4 levels, 1 level of 0 indicating that it is not important.

  When the plant construction plan support system 20 refers to the important facility information 37 shown in FIG. 9A, the plant construction plan support system 20 considers the equipment whose importance level is “O”, such as equipment # 1, as important. On the other hand, it is determined that the equipment is an equipment that is not an important equipment (hereinafter, referred to as “non-important equipment”) for the other equipment having an importance level of “X”, such as the equipment # 2.

  Further, when the important facility information 37 (FIG. 9B) in which the importance is set so that the magnitude of the number corresponds to the level of importance is referred to, the plant construction plan support system 20 has an importance of 1. The device # 1 having the importance 3 is identified as the equipment having the higher importance than the device #n.

  The important facility information 37 does not necessarily have to set information indicating whether or not it is important for all devices. If it is not necessary to determine the case where it is important in a plurality of stages, it may be configured to include only identification information of a device that is an important facility. In this case, a device having device identification information included in the important facility information 37 can be determined as an important facility.

  The important facility information 37 may be included in other information having device identification information such as the work area information 36. In other words, in addition to the work area information 36 including the identification information, position information, and work period information of the equipment used for the work, the equipment is also important for the plant safety regulations included in the important equipment information 37. You may prepare the work area information 36 containing the identification information of the apparatus for which function ensuring is requested | required.

  The determination result information 38 is, for example, at least of the determinations made by the plant construction plan support system 20 to finally determine whether the construction plan needs to be reviewed, such as the determination results of the first to sixth determinations described above. Contains information on one determination result. Note that the determination result information 38 does not necessarily need to be stored in the storage unit 28 so as to be readable, and the storage may be omitted.

  Next, regarding the plant construction plan support method according to the embodiment, the construction plan support processing procedure (from the first construction plan support processing procedure to the third construction plan support processing procedure) performed by the plant construction plan support system 20 is taken as an example. explain.

  FIG. 10 is a flowchart (flow chart) showing a processing flow of a first construction plan support processing procedure (steps S11 to S19), which is an example (first example) of a construction plan support processing procedure performed by the plant construction plan support system 20. ). In FIG. 10, the symbols in which I and II are entered in the circles are connectors that combine the processing flows.

  In the first construction plan support processing procedure (steps S11 to S19), for example, the policy presence / absence determination unit 24 and the policy applicability determination unit 25 as a determination unit that determines conditions in multiple stages include one or more systems. Processing steps are provided for supporting the plant construction plan by determining the validity of the plant indeterminate construction plan.

  In the first construction plan support processing procedure, first, the plant construction plan support system 20 makes the target device, the execution date and time of the process, and the operation state of the device at the time of isolation for an additional (undefined) work process. The input of (isolation state) information is accepted (step S11). That is, a temporary process slip X (FIGS. 11 and 12) is created and used as temporary work plan information 31.

  Subsequently, the device operation state contradiction determining unit 23 (first device operation state contradiction determining unit 23a) refers to the temporary construction plan information 31 (FIG. 1) and the confirmed construction plan information 32 (FIG. 1), and adds It is determined whether or not the operation state of the device at the time of performing the isolation in the work process is inconsistent with the operation state of the device at the time of performing the isolation in the work process of the confirmed construction plan (first determination: step S12).

  Here, the case where the operation states of the devices are contradictory and the case where there is no contradiction will be described more specifically with respect to the first determination (step S12).

FIG. 11 shows that the work process is performed for the device # 1 that is the device at the time of isolation common to both the unconfirmed work process and the confirmed work process based on the temporary work plan information 31 and the confirmed work plan information 32. it is an explanatory view showing in time series _(t 1 ~t ₇₎ the operating state at the time.

  FIG. 12 is an explanatory diagram for explaining the coincidence and disagreement of the operation state in the first determination. FIGS. 12A and 12B are respectively an unconfirmed work process illustrated in FIG. An explanatory diagram for explaining the case where the operation state of the device # 1 matches when there is a confirmed work process (when there is no contradiction in the operation state) and the case where the operation state of the device # 1 does not match (the operation state is changed) It is explanatory drawing explaining the case where a contradiction arises.

  In addition, the black circle mark shown in FIG. 12 is the start point of the isolation state when performing isolation, and the black rhombus mark is the start point of the state (restoration state) restored from the isolation.

  In the first determination (step S12), first, the first device operation state contradiction determination unit 23a refers to the temporary work plan information 31 and performs an operation on a device to be isolated in an additional work process to be planned. While acquiring the date and time and the operating state of the equipment, the work date and time and the operating state of the equipment are acquired for the equipment to be isolated in the already determined construction plan with reference to the confirmed construction plan information 32.

  Subsequently, the first equipment operation state contradiction determination unit 23a refers to the confirmed construction plan information 32 for the equipment to be isolated, and adds an additional work process from the work plan process slip for which the work process has already been confirmed. It is searched whether there are process slips that have the same device to be isolated and have at least part of the work date and time duplicated. For example, as shown in FIG. 11, the first device operation state contradiction determining unit is used as a process slip in which the devices to be isolated in the additional work process are the same and at least a part of the work date and time is duplicated. It is assumed that 23a has extracted the process slip A, the process slip B, and the process slip C.

  Subsequently, the first device operation state contradiction determining unit 23a includes each of the process slip X regarding the unconfirmed work process and the process slip regarding the extracted work process, that is, the process slip A, the process slip B, and the process slip C. For each, the operation state of the device at the end point of the overlapping timing is compared.

Endpoints of overlapping timing represented by step form X and step form A is illustrated in FIG. 12 (A), duplicate starting point overlap begins is time t _4, overlapping end point overlapping ends is a time t ₇ . Also, the end points of the overlapping timing represented by step form X and step form B is overlapped starting point overlap begins is time t _3, overlapping the end point overlapping ends is time t _5.

For a step form X a step form A, the overlap starting point t _4, an operation state of the equipment device # 1 are all "ON", the operation state of the apparatus of the overlapping end point t ₇ the device # 1 is Since both are “OFF”, the first device operation state contradiction determination unit 23a determines that the operation state of the device is not inconsistent (matched) with respect to the work process represented by the process slip A. As for the a step form X and step form B, the overlap starting point t _3, is any operating state of the apparatus # 1 of the device "ON", the overlapping end point t ₅ equipment # operation for one of the devices Since the states are both “ON”, the first device operation state contradiction determining unit 23a determines that the operation state of the device is not inconsistent (matched) with respect to the work process represented by the process slip B.

On the other hand, for the process slip X and the process slip C, the overlapping timing represented by the process slip X and the process slip C illustrated in FIG. 12B is the starting point of the isolation state in the work process represented by the process slip X and a single point of time t ₂ of the beginning of the recovery state in the working step of step form C represents. Operation state of the equipment of the device # 1 at time t _2, while the work process steps votes X represents an "ON", since the work process of step form C represents a "OFF", the first device operating state The contradiction determination unit 23a determines that the operation state of the device is inconsistent (inconsistent) with respect to the work process represented by the process slip C.

  Returning to FIG. 10, the processing flow after step S13 following the first determination (step S12) will be described.

  As a result of the first determination (step S12), when the undetermined work process is performed for each of the confirmed work processes, the operation state of the common device is consistent (in the case of NO in step S13) ), The second device operation state contradiction determination unit 23b performs the second determination.

  The second determination (step S14) is an operation plan that is read by referring to the operation process information 34 for a process to be determined as to whether or not the operation state of the common device is inconsistent with the first determination. However, the other points are not substantially different from the first determination (step S12). Therefore, in the second determination (step S14), as in the first determination (step S12), the operation state of the common device is the work process with respect to the work process in which the schedule according to the operation plan is fixed. It is determined whether or not there is a contradiction during the execution of.

  As a result of the second determination, when the operation state of the common device is contradictory at the time of execution of the work process with respect to the work process for which the schedule according to the operation plan is confirmed, then, in the case of YES in step S15, Then, it is determined whether or not the policy presence / absence determination unit 24 has, as know-how, a policy actually performed in construction that has been performed in the past (third know-how: step S16).

  When the policy presence / absence determination unit 24 refers to the know-how information (actually performed construction information) 33 and determines the presence / absence of the policy, if there is a policy (YES in step S16), then whether the policy is applicable or not When applying the policy determined to be present by the determination unit 25, it is determined whether or not compliance can be made without departing from the plant safety regulations (fourth determination: step S17). When there are a plurality of policies, the policy applicability determination unit 25 receives a selection from the plurality of policies, and performs a fourth determination on the received policies.

  As a result of the fourth determination, when it is possible to comply without departing from the plant safety regulations (YES in step S17), it is determined that the additional work process does not interfere with the confirmed work process (step S18), the first construction plan support processing procedure is terminated (END).

  On the other hand, as a result of the first determination (step S12), when the unconfirmed work process is performed with respect to each of the confirmed work processes, the operation state of the common device is inconsistent (YES in step S13). In this case, the first device operation state contradiction determining unit 23a determines that it is necessary to review the schedule of the additional work process (step S19). The determination result indicating that the review is necessary is output to, for example, the output unit 22 (FIG. 1) so that the user can recognize it.

  After the first equipment operation state contradiction determining unit 23a determines that reexamination is necessary, the process flow of the first construction plan support processing procedure returns from step S19 to step S11, and a new additional work after reexamination. Accepts process input.

  In addition, when there is no measure in the result of the third determination (NO in step S16) or in the case of failure to comply with the plant safety regulations in the result of the fourth determination (NO in step S17), the first construction The processing flow of the plan support processing procedure proceeds to step S19, and further returns to step S11. In other words, if there is no measure in the result of the third determination or if the plant safety regulations cannot be observed in the result of the fourth determination, the additional work process becomes a determination result that requires a reexamination of the schedule, etc. The support system 20 receives an input of a new additional work process after the review.

  The first construction plan support processing procedure described above is an example in which the fourth determination is subsequently performed when there is a policy in the result of the third determination, but the first construction plan support processing procedure is not necessarily the same. It is not necessary to perform the fourth determination. For example, if the operation status of the device is inconsistent with the additional work process, stop until determining whether there is a measure for avoiding the contradiction, or determine whether there is a measure for avoiding the contradiction. If there is a problem, it is possible to extract a measure for avoiding the contradiction and stop it before presenting it to the user. That is, if at least the third determination is made, the remaining processing steps are not necessarily performed.

  FIG. 13 and FIG. 14 are flow charts (flow charts) showing an example of the construction plan support processing procedure performed by the plant construction plan support system 20, respectively. FIG. 13 shows a second example of the construction plan support processing procedure. FIG. 14 shows a third construction plan support processing procedure (steps S31, S32, S34 to S37) as a third example of the construction plan support processing procedure. S39). In FIG. 13 and FIG. 14, symbols in which III is written in circles are connectors that combine the processing flows.

  The second construction plan support processing procedure is different from the first construction plan support processing procedure in that it further includes a step of determining the presence or absence of interference in the work area. There is no difference. Therefore, in the description of this procedure, the description will focus on the differences in the first construction plan support processing procedure, and a duplicate description will be omitted.

  In the second construction plan support processing procedure, first, the processing steps of the first construction plan support processing procedure (steps S11 to S19: FIG. 10) are performed (step S31: FIG. 13). The size of the work area corresponding to the presence or absence of the work area is set, and the presence or absence of interference in the work area is determined (fifth determination: step S34).

  When the work area interference determination unit 26 determines the presence or absence of interference in the work area, if there is important equipment information 37 (YES in step S32), the size of the work area is set in consideration of the importance of the equipment. Above (step S33), the presence / absence of interference in the work area is determined (step S34). On the other hand, if there is no important equipment information 37 (NO in step S32), the size of the work area is set according to the work area information 36, and the presence / absence of interference in the work area is determined (step S34).

  As a result of the determination, when there is no interference in the work area (NO in step S35), it is determined that the additional work process does not interfere with the confirmed work process (step S36), and the second construction plan support processing procedure End (END).

  On the other hand, when the work area interferes (in the case of YES in step S35), the work area interference determination unit 26 determines that the additional work process needs to be reexamined (step S37). After the work area interference determination unit 26 determines that reexamination is necessary, the processing flow of the second construction plan support processing procedure returns from step S37 to step S31 to input a new additional work process after reexamination. Accept.

  The above-described second construction plan support processing procedure takes into account the importance of the equipment with reference to the important equipment information 37 before the fifth determination (step S34), and the size considering the importance of the equipment. Is the example of performing interference determination of the work area (fifth determination: step S34), but the fifth determination (step S34) illustrated in FIG. After step S34), the interference determination of the work area (sixth determination: step S39) may be performed in consideration of the condition according to the level of importance of the equipment.

  Further, in the setting of the size of the work area in consideration of the importance in the second construction plan support processing procedure (step S33), when the equipment related to the work process is an important facility, the work process is determined as an indeterminate work process. The size of the work area, such as prohibiting work on the same floor or in the same building within the same period, is not specified directly, but restricts the size of the work area. This includes a case where the size of the work area that substantially prohibits interference is set by adding a condition (constraint condition).

  That is, the setting of the size of the work area in consideration of the importance described above is performed when there are a plurality of pieces of work area size information included in the important equipment information 37 (when the size range is a plurality of patterns). The number of work areas may be set differently depending on the level of importance even if there is one (when the size range is one pattern).

  For example, in the work area information 36 shown in FIG. 7A described above, the work area size information is one for each device. Here, when both the device # 1 and the device #n are important facilities and a constraint condition for prohibiting the work on the same floor within the same period for the important facilities is added, the work area interference determination unit 26 When considering the importance obtained by referring to the important facility information 37, the size of the work area is set as the entire first floor (1F) (step S33), or the size of the work area of the work area information 36 is set. After performing interference determination based on information (fifth determination: step S34), a condition determination based on a separately added "prohibit work on the same floor within the same period" constraint condition (sixth determination: step S39) ).

  As described above, even if the size information of the work area included in the important equipment information 37 is one, the plant construction plan support system 20 adds the constraint condition so that the important equipment and the non-important equipment are substantially separated. Thus, the presence or absence of interference in the work area can be examined by changing the criteria for determining the size of the work area.

  As described above, according to the plant construction plan support system 20, the first to third construction plan support processing procedures, and the construction plan support PG, it is possible to examine whether the additional work process interferes with the fixed work process. In addition, even if the additional work process interferes with the fixed work process, it is confirmed whether there is any know-how accumulated in the past construction plan, and if there is, use that know-how to establish safety regulations. It is possible to examine whether or not it can be performed without departing from the scope. Therefore, by utilizing the know-how accumulated in the construction plan implemented in the past, it is possible to examine the process more flexibly and broadly than before, such as proposing measures that enable additional work processes without departing from the safety regulations. it can.

  Moreover, according to the plant construction plan support system 20, the first to third construction plan support processing procedures, and the construction plan support PG, the on-site situation that changes dynamically such as important equipment facilities that change according to the system operation process can be obtained. The feasibility of the considered construction plan can be determined. Therefore, it is possible to prevent the occurrence of a work plan return due to a lack of examination of the field situation that changes dynamically.

  Furthermore, according to the plant construction plan support system 20, the first to third construction plan support processing procedures, and the construction plan support PG, the importance can be set in a plurality of stages for the important equipment. The feasibility of the construction plan can be determined in consideration of the degree of degree.
