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 for power generation, chemistry, food, steelmaking, environment, etc., in addition to regular inspections that are carried out regularly, construction work may be required irregularly. When carrying out construction work at a plant, laws and regulations are stipulated from the viewpoint of industrial security, and it is necessary to formulate a work plan that takes these laws and regulations into consideration.

For example, in the case of a power plant, Article 42 of the Electricity Business Act requires the formulation and compliance of safety regulations, so it is necessary to formulate a work plan that takes into consideration the safety management guidelines stipulated in the safety regulations.

As a system that supports the formulation of work plans such as periodic inspections of plants, for example, from the viewpoint of appropriately managing the periodic inspection processes in nuclear power plants, inspection processes are added or changed so that interference between inspection processes does not occur. A process control system has been proposed to support this.

Japanese Unexamined Patent Publication No. 2010-122053

In the construction plan for the power plant, the implementation time of the new construction plan will be examined after confirming the plant system operation process and the feasibility of the construction plan for which the plan has already been finalized. In this study, the constraints of the plant system will be considered so as not to deviate from the safety regulations.

For example, in a conventional plant construction plan support system such as the process control system described in Patent Document 1, it is determined whether or not there are devices to be worked on at the same time, and the devices to be inspected are duplicated. The presence or absence of the equipment is used to determine the presence or absence of interference between the fixed inspection process and the additional inspection process.

In addition, the results obtained by determining the inspection time, system isolation (isolation) time, unit test time, and test run time of the equipment for each equipment to be inspected, and the equipment required for operating each plant system. From the information in, determine the operable time, isolation time, unit test time, and test run time of each plant system. Furthermore, it is determined whether or not the operational time, isolation time, unit test time, and test run time of each plant system comply with the safety regulations.

However, in the conventional plant construction plan support system such as Patent Document 1, although it is possible to determine whether or not there is interference between the (fixed) inspection process whose schedule has already been determined and the additional inspection process, there is interference. It is not possible to consider and propose a plan to avoid interference on the system when it is determined that there is. Therefore, when the system determines that there is interference, there is a problem that the user needs to reexamine the construction plan, create a new inspection process, and determine the presence or absence of interference again.

In addition, when formulating a construction plan, it is important to ensure that important equipment related to system operation is damaged and that system operation is hindered. In order to reliably avoid damage to important equipment related to system operation, it is necessary to consider not only the isolation timing and safety regulations, but also the work environment at the site, etc. The plant construction plan support system does not consider the work environment at the site.

Therefore, although there are no problems with isolation timing or safety regulations, the construction plan was approved in the middle of the process, including processes that could damage important equipment related to system operation depending on the work environment at the site. Construction may be in progress. In this case, it is necessary to suddenly review the process (so-called backtracking work) 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.

The present invention has been made in view of the above circumstances, and provides a plant construction plan support system, a construction plan support method, and a construction plan support program that reduce the burden on the user required for examining the construction plan of the plant.

FIG. 1 is a schematic view 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 determining the necessity of reviewing a construction plan by determining a plurality of conditions step by step, and more specifically, additional work such as an undecided construction plan. If the process interferes with a fixed work process, whether or not the plant can be continued to operate within the range that does not deviate from the safety regulations by utilizing the know-how accumulated in the construction plan implemented in the past, that is, in the plant system of the plant. After further examining whether or not the constraint conditions can be avoided, the necessity of reviewing the construction plan is determined.

A fixed work process is a work process whose schedule has already been determined. The fixed work process includes, for example, a work process of construction work whose schedule is fixed and a work process according to an operation plan of a plant whose schedule is fixed.

In the plant construction plan support system 20, for example, the operating state of the equipment in the additional work process is the operating state of the equipment in the work process of the construction plan whose schedule is fixed (hereinafter referred to as “fixed construction plan”). A function for determining whether or not there is a contradiction, and a second function for determining whether or not there is a contradiction with the operating state of the equipment in the work process according to the operation plan of the plant whose schedule is fixed. The function to make a judgment, the function to make a third judgment to judge the existence of accumulated know-how when it is inconsistent with the operating state of the equipment in the work process according to the operation plan of the plant whose schedule is fixed, and the third It has a function of outputting the determination results of the first, second and third determinations.

When the plant construction plan support system 20 has accumulated know-how, whether or not it is possible to avoid the constraint conditions of the plant system by utilizing this know-how, and more specifically, whether or not it can comply with the safety regulations of the plant. It may have a function of performing a fourth determination for determination and a function of outputting a determination result of the fourth determination.

In the plant construction plan support system 20, the area where the equipment used in the work process according to the operation plan of the plant is used and the area where the equipment used in the additional work process are used interfere with each other within each usage period. It may have a function of performing a fifth determination for determining whether or not to do so, and a function of outputting a determination result of the fifth determination. In addition, when making the fifth judgment, the importance information set for the equipment used in the work process according to the operation plan of the plant should be taken into consideration, and the target for which the fifth judgment is made is important. It may be limited to devices with a high degree of importance, or further interference judgment according to the degree of importance, that is, interference judgment (sixth judgment) based on different criteria such as the size of the area being different from the fifth judgment. You may.

The plant construction plan support system 20 having the above-mentioned functions includes, for example, a storage device having a processor such as a CPU (Central Processing Unit) and a storage circuit 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-mentioned functions on the computer, cooperate with each other. It is realized by.

In other words, whether or not the construction plan support PG can avoid the constraint conditions in the plant system by utilizing the know-how accumulated by the construction plan implemented in the past when the additional work process interferes with the fixed work process. This is a program that causes a computer to execute a processing procedure (hereinafter referred to as "construction plan support processing procedure") that determines the necessity of reviewing the construction plan and supports the construction plan after further studying. By executing the construction plan support PG, the plant construction plan support system 20 provided with specific means for executing the construction plan support processing procedure in the computer is realized.

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

Here, various information 31 to 38 displayed inside the storage unit 28 such as the temporary construction plan information 31 and the final construction plan information 32 are read out (read) as necessary when executing the construction plan support processing procedure. ) Or information to be written (written).

The input unit 21 is realized by, for example, an input device connected to the computer via an interface or an input means such as a keyboard or a mouse included in the computer itself. The input unit 21 receives the input of information and gives the received information to the control unit 29. The information input from the input unit 21 includes, for example, an execution request for various processes, an input of information such as a temporary construction plan, and a request for setting various conditions.

The output unit 22 is realized by, for example, a display device connected to the computer via an interface, a display means such as a display provided by the computer itself, a printing means such as a printer connected to the computer via an interface, and a display function. It has an output function such as a printing function and a printing function.

When the output unit 22 having a display function receives the display request, the output unit 22 displays the contents corresponding to the display request. Further, when the output unit 22 having a print function receives a print request, the output unit 22 prints and outputs the contents corresponding to the print request.

The device operation state contradiction determination unit 23 includes a first device operation state contradiction determination unit 23a and a second device operation state contradiction determination unit 23b.

The first device operation state inconsistency determination unit 23a refers to, for example, the temporary construction plan information 31 and the final construction plan information 32, and the operation of the equipment at the time of isolation execution in the added temporary (unconfirmed) construction plan. It is determined whether the state and the operating state of the equipment at the time of isolation in the already confirmed construction plan are inconsistent or match (or not).

The determination of whether or not the operating states of the devices are inconsistent (first inconsistency determination) performed by the first device operating state contradiction determination unit 23a corresponds to the above-mentioned first determination. The first device operating state contradiction determination unit 23a outputs the determination result to the output unit 22 or stores the determination result information 38 in the storage unit 28.

The second equipment operation state contradiction determination unit 23b refers to, for example, the temporary construction plan information 31 and the operation process information 34, and in the operation state of the equipment in the undecided construction plan and the work process according to the already determined operation plan. Determine if the operating state of the device is inconsistent or inconsistent (or not).

The determination of whether or not the operating states of the devices are inconsistent (second inconsistency determination) performed by the second device operating state contradiction determination unit 23b corresponds to the above-mentioned second determination. The second device operating state contradiction determination unit 23b outputs the determination result to the output unit 22 or stores the determination result information 38 in the storage unit 28.

Even if there is a contradiction in the operating state of the equipment, the policy presence / absence determination unit 24 works without affecting the operation plan that has been finalized (without deviating) while complying with the safety regulations by taking some measures. It is a judgment means provided in consideration of the fact that there is room for establishing. The policy presence / absence determination unit 24 refers to the know-how information 33 to determine the presence / absence of the policy actually implemented in the construction work that has been carried out in the past in the classification in the plant to which the equipment having the inconsistent operating state belongs. ..

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

The policy applicability determination unit 25 has a function of determining whether or not a policy that has been selected from the policies that the policy presence / absence determination unit 24 has determined to have a policy can be applied without deviating from the safety regulations of the plant. When the policy applicability determination unit 25 accepts a selection from the measures determined by the policy presence / absence determination unit 24 to have a policy, it refers to the know-how information 33 and the safety regulation information 35 and selects within a range that does not deviate from the safety regulation of the plant. Determine if the policy accepted is applicable.

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

In addition, the determination of applicability of the measure may be the final stage determination of whether or not the additional work process interferes with the fixed work process. In this case, the measure applicability determination unit 25 outputs the final determination result of whether or not the additional work process interferes with the fixed work process to the output unit 22.

In the work area interference determination unit 26, the work process in the undecided construction plan is within the work period in which the work process is performed with respect to the work process in the construction plan in line with the operation plan of the plant system whose schedule has already been fixed. It has a function to determine whether or not the work areas overlap (interfere).

The work area interference determination unit 26 first refers to the work area information 36, and determines the equipment used in the work process in the undetermined construction plan, the position of the equipment, the size of the work area, and the work period of the plant system. Determine 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 make a determination in consideration of the importance of the equipment. In this case, the work area interference determination unit 26 changes the size (wideness) of the interference prohibition area that prohibits interference, or changes the number of determination steps, depending on the presence or absence of importance and the difference in height. judge.

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

Since the fifth determination and the sixth determination described above are final stage determinations for determining whether or not the additional work process interferes with the fixed work process, the determination performed by the work area interference determination unit 26 is performed. The results also include the final determination of whether the additional work process interferes with the fixed work process.

The storage unit 28 includes a storage area capable of reading (reading) and writing (writing) information, and has a function of holding information in the storage area. The storage unit 28 provides a storage area 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. The information provided and necessary for executing each process is read (read) and written (written).

When executing the construction plan support processing procedure, in the storage unit 28, for example, temporary construction plan information 31, final 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 equipment information 37 and the determination result information 38 is read and written as appropriate. Details of each information 31 to 38 will be described later.

The control unit 29 is a processing unit that controls the 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), and a policy presence / absence determination unit 24. It has a function of exchanging information with each other and controlling the policy applicability determination unit 25, the work area interference determination unit 26, and the storage unit 28.

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

For example, when there is a request for displaying 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 determines the policy presence / absence for which the display request has been made. At the same time as receiving the result, a display command is given to display the determination result received according to the display request on the display unit which is an example of the output unit 22. The determination result is displayed on the display unit according to the display command.

The plant construction plan support system 20 may include an equipment state contradiction determination unit 23 (23a, 23b) and a policy presence / absence determination unit 24, and may be configured so that information can be exchanged, and the policy is not necessarily applied. It is not necessary to include the propriety determination unit 25 and the work area interference determination unit 26.

Further, in the plant construction plan support system 20, the policy presence / absence determination unit 24 and the policy applicability determination unit 25 may be integrated into a single configuration by aggregating the functions of both determination units.

Further, in the plant construction plan support system 20 realized by the cooperation of the computer and the construction plan support PG, an output device such as an input device or a display device connected via an interface means with an external device provided in the computer is provided. It may be applied as an input means or an output means. That is, in the plant construction plan support system 20, an input device which is an external device can be applied as an input unit 21, and an output device which is an external device can be applied as an output unit 22.

The circle “◯” and the cross mark “x” in FIG. 5 (A) indicate that the process is carried out or not, respectively.

Further, as shown in FIG. 5B, for example, the operation process information 34 includes lower (more detailed) work such as process A1 included in work process A, which is a higher work process, as lower information. For each process, it has information indicating the operating state of the equipment required for each equipment required for performing the lower 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 for determining, for example, whether or not the conditions required by the safety regulations for the work process to be performed such as the work process A, that is, the conditions for complying with the safety regulations are satisfied. It is a security regulation compliance judgment logic.

In the plant construction plan support system 20, for example, regarding the implementation of the work process A, it is necessary to make a judgment in the procedure (steps S1 to S4) according to the safety regulation compliance determination logic shown in FIG. 6 and to comply with the safety regulation. Judge the conditions to be considered.

In the safety regulation compliance determination logic exemplified in FIG. 6, the conditions required for complying with the safety regulation are determined from the condition (i) according to the state of the equipment X in the plant. This is a logic for determining which condition of the condition (iii).

When the state of the equipment X (step S1) is "operation", it becomes the "condition (i)" in which the safety regulations can be observed without performing both the steps A1 and A2 (step S2). When the state of the equipment X (step S1) is "stopped", the safety regulations can be complied with if one of the steps (step A1 or step A2) of the steps A1 and A2 is performed "condition (ii)". "(Step S3). When the state of the equipment X (step S1) is “other”, it becomes the “condition (iii)” (step S4) in which the safety regulations can be observed if both the steps A1 and A2 are carried out.

When it is necessary to determine whether or not the plant construction plan support system 20 can comply with the safety regulations, whether or not the plant construction plan support system 20 satisfies the conditions (i) and the like obtained as a result of the determination according to the safety regulation compliance determination logic. By determining, it is determined whether or not the security regulations can be complied with.

FIG. 7 (FIGS. 7 (A) and 7 (B)) is an explanatory diagram showing an example of the work area information 36, and FIG. 7 (A) 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.

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

The work area information 36 (FIG. 7) includes, for example, identification information of equipment used for work, position information of work area, size information of work area, and work period information. For the definition of position information, for example, one point (origin) on the space is selected, a three-dimensional Cartesian coordinate system with the selected one point as the origin is set, and the work area is divided into a rectangular parallelepiped space area. Do by.

The location information exemplified in FIGS. 8 (A) and 8 (B) is an example in the case where the work area is indoors of the first building (referred to as “building # 1” in the figure), and is high. The above is defined by dividing each floor 45 (45a to 45d) of the building. Regarding the position of the plane (area) of each floor, the plane area 46 of each floor is equally divided into p (plurality of p) in the vertical direction (X-axis direction) and the horizontal direction (Y-axis direction), respectively. It is defined by q (plural q is) divided plane regions 47.

For example, the positions indicated by the position information of the area "X2Y2" and the floor "1F", which are examples of the position information shown in FIGS. 7 (A) and 7 (B), are the definitions of the position information exemplified in FIG. According to this, it is the floor 45c on the first floor (1F) of the building, and the vertical direction is the second range "X2" from the reference position (origin O) and the horizontal direction is the second range "X2" from the reference position (origin O). It is a division plane region 47a where "Y2" intersects.

The size information of the work area is information indicating an area that hinders the execution of self-work when the area interferes with other work or the like. In other words, the size of the work area represents the size of the interference prohibition area. The size information 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 with respect to the range to be a circular area. Defined by information.

The size "X1, Y1" of "equipment # 1" shown in FIG. 7 is a definition of the size based on the size of the divided plane region 47, and is centered on the area "X2Y2" indicating its own position. It is shown that the size is one in the X-axis direction and one in the Y-axis direction.

The size information included in the work area information 36 may include a plurality of size information indicating different sizes when considering the importance of the equipment described later. For example, as shown in FIG. 7B, the importance may be set in two stages of high and low, and different sizes may be set according to the high and low importance.

Further, the size information is information that directly defines 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 defines the size. Information that defines the size may be used for.

When there is information that indirectly defines the size, for example, the size can be classified into several patterns according to the type of device, and the model code indicating the type of device and the type of device can be used. In some cases, device management information (not shown) associated with size information indicating the corresponding size is prepared. In this case, the model code associated with the size pattern indirectly defines the size, and this model code can be used as the size information included in the work area information 36.

9 (FIGS. 9 (A) and 9 (B)) are explanatory views showing an example of important equipment information 37, and FIG. 9 (A) shows a case where the importance is set depending on whether or not the important equipment information 37 is important. The explanatory diagram shown in FIG. 9B is an explanatory diagram showing a case where the important case is divided into a plurality of stages such as three stages and the importance is set.

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

Here, the importance means the degree of importance including the case where it is not important. In the important equipment information 37 exemplified in FIG. 9 (A), a circle mark (“○” mark in FIG. 9 (A)) indicating that the importance is important and a cross mark (FIG. 9) indicating that the importance is not important. In (A), it is set to "x"). Further, in the important equipment information 37 illustrated in FIG. 9B, the importance is important and the degree of importance is shown in three stages of 1 (importance: low) to 3 (importance: high). It is set to a total of 4 stages of 1 stage of 0 indicating that it is not important.

When the plant construction plan support system 20 refers to the important equipment information 37 shown in FIG. 9 (A), the plant construction plan support system 20 places importance on equipment whose importance is circled “○” such as equipment # 1. While it is judged to be equipment, other equipment such as equipment # 2 whose importance is marked with a cross "x" is judged to be non-important equipment (hereinafter referred to as "non-important equipment").

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

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

Further, the important equipment information 37 may be included in other information having device identification information such as work area information 36. That is, in addition to the work area information 36 which includes the identification information, the position information and the work period information of the equipment used for the work, as the equipment which is important for the safety regulation of the plant included in the important equipment information 37. The work area information 36 including the identification information of the device for which the function is required to be ensured may be prepared.

The determination result information 38 is at least one of the determinations made by the plant construction plan support system 20 for finally determining the necessity of reviewing the construction plan, such as the determination results of the first to sixth determinations described above. Contains information on one determination result. The determination result information 38 does not necessarily have to be readable and stored in the storage unit 28, and the storage may be omitted.

Next, regarding the plant construction plan support method according to the embodiment, the construction plan support processing procedure (first construction plan support processing procedure to 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 flow chart (flow chart) showing a processing flow of the first construction plan support processing procedure (steps S11 to S19), which is an example (first example) of the construction plan support processing procedure performed by the plant construction plan support system 20. ). In addition, the symbols shown in FIG. 10 in which I and II are entered in ◯ are the couplers that connect the processing flows, respectively.

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 means for determining conditions in multiple stages include one or more systems. Provide processing steps to support the plant construction plan by determining the validity of the plant's undetermined construction plan.

In the first construction plan support processing procedure, first, the plant construction plan support system 20 uses the target equipment, the date and time of the process, and the operating state of the equipment at the time of isolation for the additional (undetermined) work process. The input of the (isolation state) information is accepted (step S11). That is, a temporary process sheet X (FIGS. 11 and 12) is created and used as the temporary construction plan information 31.

Subsequently, the equipment operation state contradiction determination unit 23 (first equipment operation state contradiction determination unit 23a) additionally refers to the temporary construction plan information 31 (FIG. 1) and the final construction plan information 32 (FIG. 1). It is determined whether or not the operating state of the equipment during the execution of isolation in the work process is inconsistent with the operating state of the equipment during the execution of isolation in the work process of the final construction plan (first determination: step S12).

Here, the first determination (step S12) will be described more specifically when the operating states of the devices are inconsistent and when they are not inconsistent.

FIG. 11 shows the work process execution of the device # 1, which 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 final work plan information 32. It is explanatory drawing which represented the operation state at time in time series (t _{1 to t 7).}

FIG. 12 is an explanatory diagram for explaining the matching and disagreement of the operating states in the first determination, and FIGS. 12A and 12B are the undetermined work steps exemplified in FIG. 11, respectively. An explanatory diagram for explaining the case where the operating state of the device # 1 matches (when there is no contradiction in the operating state) when there is a fixed work process and the case where the operating state of the device # 1 does not match (in the operating state). It is explanatory drawing explaining (when a contradiction occurs).

The black circle mark shown in FIG. 12 is the start point of the isolation state when the isolation is executed, and the black diamond mark is the start point of the state recovered from the isolation (restoration state).

In the first determination (step S12), first, the first equipment operation state contradiction determination unit 23a refers to the temporary construction plan information 31 and works on the equipment to be isolated in the 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 confirmed construction plan by referring to the finalized construction plan information 32.

Subsequently, the first device operating state contradiction determination unit 23a refers to the finalized construction plan information 32 for the device to be isolated, and adds an additional work process from the process sheet of the construction plan for which the work process has already been finalized. It is searched whether there is a process sheet in which the equipment to be isolated in the above is the same and at least a part of the work date and time overlaps. For example, as shown in FIG. 11, 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 overlaps, the first device operation state contradiction determination unit It is assumed that 23a extracts the process sheet A, the process sheet B, and the process sheet C.

Subsequently, the first device operating state contradiction determination unit 23a of the process sheet X relating to the unconfirmed work process and the process sheet related to the extracted confirmed work process, that is, the process sheet A, the process sheet B, and the process sheet C. For each, the operating states of the devices at the end points of the overlapping timings are 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 it 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 operating state inconsistency determination unit 23a determines that the device operating states are not inconsistent (matched) with respect to the work process represented by the process sheet 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 all the states are "ON", the first device operating state inconsistency determination unit 23a determines that the device operating states are not inconsistent (matched) with respect to the work process represented by the process sheet B.

On the other hand, with respect to the process sheet X and the process sheet C, the overlapping timing represented by the process sheet X and the process sheet C illustrated in FIG. 12B is the starting point of the isolation state in the work process represented by the process sheet 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 operating state of the device is inconsistent (mismatch) with respect to the work process represented by the process sheet 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 operating states of the common devices do not contradict each of the confirmed work processes at the time of executing the undetermined work process (NO in step S13). ), The second device operating state contradiction determination unit 23b makes the second determination.

In the second determination (step S14), the operation plan read out by referring to the operation process information 34 by the process to be determined whether or not the operating states of the common devices are inconsistent with respect to the first determination. Although it differs in that it is a work process according to the above, the other points are substantially the same as those in the first determination (step S12). Therefore, in the second determination (step S14), as in the first determination (step S12), the operating state of the common equipment is the work process for the work process in which the schedule according to the operation plan is fixed. It is determined whether or not there is a contradiction at the time of execution of.

As a result of the second determination, when the operating states of the common equipment are inconsistent at the time of executing the work process with respect to the work process whose schedule is determined according to the operation plan (YES in step S15), subsequently. , The policy presence / absence determination unit 24 determines whether or not the policy actually implemented in the construction completed in the past is possessed as know-how (no know-how) (third determination: step S16).

As a result of the policy presence / absence determination unit 24 determining the presence / absence of the policy by referring to the know-how information (actually performed construction information) 33, if there is a policy (YES in step S16), then whether or not the policy can be applied. The determination unit 25 determines whether or not it is possible to comply with the safety regulations of the plant when applying the measures determined to exist (fourth determination: step S17). When there are a plurality of measures, the measure applicability determination unit 25 accepts a selection from the plurality of measures and makes a fourth determination regarding the accepted measures.

As a result of the fourth determination, if it is possible to comply with the safety regulations of the plant without departing from it (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 completed (END).

On the other hand, as a result of the first determination (step S12), when the operating states of the common devices are inconsistent at the time of executing the undetermined work process for each of the confirmed work processes (YES in step S13). In the case of), the first device operating state contradiction determination unit 23a determines that it is necessary to reexamine the schedule of the additional work process (step S19). The determination result indicating that reexamination is necessary is output to, for example, the output unit 22 (FIG. 1) so that the user can recognize it.

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

In addition, when there is no measure in the result of the third judgment (NO in step S16) or when the safety regulation of the plant cannot be observed in the result of the fourth judgment (NO in step S17), the first construction work. The processing flow of the planning support processing procedure proceeds to step S19, and further returns to step S11. That is, if there is no measure in the result of the third judgment or if the safety regulations of the plant cannot be observed in the result of the fourth judgment, the judgment result is that the additional work process needs to be reexamined such as the schedule, and the plant construction plan. The support system 20 accepts input of a new additional work process after reexamination.

The above-mentioned first construction plan support processing procedure is an example in which the fourth determination is subsequently performed when there is a measure in the result of the third determination, but the first construction plan support processing procedure is not necessarily It is not necessary to make a fourth determination. For example, when the operating state of the device is inconsistent with respect to the additional work process, it is stopped until it is determined whether or not there is a measure to avoid the contradiction, or as a result of determining whether or not there is a measure to avoid the contradiction, the measure to avoid the contradiction. If there is a contradiction, it is possible to extract a measure to avoid the contradiction and stop it until it is presented to the user. That is, if at least the third determination is made, the remaining processing steps do not necessarily have to be performed.

13 and 14 are flow charts (flow charts) showing a processing flow of an example of the construction plan support processing procedure performed by the plant construction plan support system 20, respectively, and FIG. 13 is a second example of the construction plan support processing procedure. 2nd construction plan support processing procedure (steps S31 to S37), 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). It should be noted that the symbols shown in FIGS. 13 and 14 in which III is entered in ◯ are the couplers that bind the processing flows.

The second construction plan support processing procedure differs from the first construction plan support processing procedure in that it further includes a step for determining the presence or absence of interference in the work area, but the other points are substantially substantive. Must be. Therefore, in the description of this procedure, the differences in the first construction plan support processing procedure will be mainly described, and duplicate explanations will be omitted.

In the second construction plan support processing procedure, first, the processing steps (steps S11 to S19: FIG. 10) of the first construction plan support processing procedure are performed (steps S31: FIG. 13), followed by important equipment information 37. The size of the work area is set according to the presence or absence of the work area, 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, when the important equipment information 37 is present (YES in step S32), the size of the work area is set in consideration of the importance of the equipment. Above (step S33), it is determined whether or not there is interference in the work area (step S34). On the other hand, when 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 then the presence or absence of interference in the work area is determined (step S34).

As a result of the determination, if 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).

On the other hand, when the work areas interfere (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, and inputs a new additional work process after the reexamination. Accept.

In the second construction plan support processing procedure described above, the importance of the equipment is taken into consideration by referring to the important equipment information 37 before the fifth determination (step S34), and the size in consideration of the importance of the equipment. Is an example in which interference determination (fifth determination: step S34) of the work area is performed by setting, but as in the third construction plan support processing procedure exemplified in FIG. 14, the fifth determination (fifth determination: step S34) is performed. After step S34), the interference determination of the work area (sixth determination: step S39) may be performed separately in consideration of the conditions according to the importance of the equipment.

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

That is, the above-mentioned setting of the size of the work area in consideration of the importance is performed when there is a plurality of information on the size of the work area included in the important equipment information 37 (when the range of the size is a plurality of patterns). The size of the work area is not limited, and even if it is one (when the size range is one pattern), the size of the work area may be set differently depending on the degree of importance.

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

In this way, even if the size information of the work area included in the important equipment information 37 is one, in the plant construction plan support system 20, by adding a constraint condition, the important equipment and the non-important equipment are substantially combined. It is possible to examine the presence or absence of interference in the work area 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 or not the additional work process interferes with the fixed work process. Furthermore, even if the additional work process interferes with the fixed work process, check whether there is any know-how accumulated by the construction plan implemented in the past, and if there is, use that know-how to establish safety regulations. It is possible to examine whether or not it can be done within a range that does not deviate. Therefore, it is possible to consider a wider range of processes than before, such as proposing measures that enable additional work processes within the range that does not deviate from the safety regulations by utilizing the know-how accumulated from the construction plans implemented in the past. it can.

In addition, 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 conditions that change fluidly, such as important equipment that changes according to the system operation process, can be seen. It is possible to judge the feasibility of the construction plan in consideration. Therefore, it is possible to prevent the occurrence of backtracking of the construction plan due to insufficient consideration of the fluidly changing site conditions.

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, it is possible to set the importance of important equipment in multiple stages, which is important. The feasibility of the construction plan can be judged in consideration of the degree.
