Description

Construction plan management system and construction plan management method

[0001] The present disclosure relates to a construction plan management system and a construction plan management method.

[0002] When constructing a large-scale plant, a huge amount of design drawings is created. Also, when constructing a large-scale plant, a huge amount of materials is required. In order to efficiently proceed with the design and construction of the plant, it is necessary to plan and manage the schedule for creating the design drawings and the schedule for procuring materials.

[0003] The design materials management system described in Patent Document 1 uses identification information attached to the design materials to record location information where the design materials are stored in association with CAD drawing information on which the design materials are used. The design materials management system described in Patent Document 1 can recognize construction progress information from CAD drawings and can identify design materials required for the next task.

[0004] The production plan optimization system described in Patent Document 2 manages assembly plans for made-to-order products and procurement plans for parts required for assembling the made-to-order products. The production plan optimization system described in Patent Document 2 creates a procurement plan for parts required for assembling the made-to-order products in accordance with the assembly plans for the made-to-order products.

[0006] Construction of equipment in a plant can begin once the design drawings for the equipment to be constructed are completed and the materials to be used in the design drawings for the equipment to be constructed (delivery and allocation) are completed. However, conventional construction plan management systems such as those described in Patent Documents 1 and 2 procure the necessary materials based on the design drawings after the creation of the design drawings is complete. In other words, conventional construction plan management systems do not manage the design drawing creation schedule in association with the material procurement schedule, and therefore cannot perform allocation work to determine which equipment the materials will be used for before the creation of the design drawings is complete. As a result, conventional construction plan management systems not only lengthen construction periods but also make it impossible to grasp the future possible construction volume that can be estimated from the design drawing creation schedule and the material procurement schedule.

[0007] The present disclosure has been made in consideration of these circumstances, and aims to provide a construction plan management system and construction plan management method that can grasp the amount of construction work that can be done in the future by managing the schedule for creating design drawings and the schedule for procuring materials, determining the materials required for equipment based on the design drawings that are being created even if the creation of the design drawings is not completely completed, and performing allocation work to determine which equipment the procured materials will be used for.

[0008] In order to solve the above problems, the present disclosure proposes the following means: A construction plan management system according to a first aspect of the present disclosure is a system for managing construction work of a plant including a plurality of equipment modules, and includes: an allocation processing unit that allocates materials in accordance with an issuance schedule for drawings for each equipment module determined based on area information for the construction of the plurality of equipment modules and function information for the plurality of equipment modules, and a delivery schedule for materials commonly used in the construction of the plurality of equipment modules, and a construction possible amount calculation unit that calculates a construction possible amount in accordance with the issuance schedule and a material allocation result output by the allocation processing unit.

[0009] A construction plan management method according to a second aspect of the present disclosure is a method for managing construction work of a plant including a plurality of equipment modules, and includes an input data acquisition step of acquiring an issuance schedule of drawings for each equipment module determined based on area information where the plurality of equipment modules are to be constructed and function information of the plurality of equipment modules, and a delivery schedule of materials to be commonly used in the construction of the plurality of equipment modules, a material allocation step of allocating the materials based on the issuance schedule of the drawings and the delivery schedule of the materials, and a possible construction amount calculation step of calculating the possible construction amount based on the issuance schedule and the result of the material allocation.

[0010] According to the construction plan management system and construction plan management method disclosed herein, it is possible to manage the schedule for creating design drawings and the schedule for procuring materials, and even if the creation of design drawings has not been completely completed, it is possible to grasp the amount of construction work that can be done in the future by determining the materials required for equipment based on the design drawings that are being created and performing allocation work to determine which equipment the procured materials will be used for.

[0012] An embodiment of the present disclosure will be described with reference to Fig. 1 to Fig. 16. Fig. 1 is a diagram showing a construction plan management system 1 according to this embodiment.

[0013] [Construction plan management system 1] The construction plan management system 1 is a system that manages and adjusts construction plans for large-scale plants. The construction plan management system 1 includes an input unit 10, a storage unit 20, a display unit 30, and a calculation unit 40.

[0014] [Input Unit 10] The input unit 10 has an operation input unit 11 and a data input unit 12. The operation input unit 11 is an operation device into which a user inputs operations, such as a keyboard, a mouse, or a touch panel. The data input unit 12 is a device that reads input data, such as a memory reader that reads data stored in a non-volatile memory such as a memory card. The data input unit 12 may also be a device that receives input data via a network. The operation input and input data input to the input unit 10 are acquired by the calculation unit 40.

[0015] [Storage Unit 20] The storage unit 20 is a non-volatile recording medium that stores a construction plan management program that operates the calculation unit 40 and data necessary for construction plan management, and is, for example, a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage unit 20 stores drawing information 21, a priority matrix 22, priority weight information 23, a material delivery schedule 24, allocation method selection information 25, a drawing issuance schedule 26, and a material allocation result 27.

[0016] 2 is a diagram showing drawing information related to drawings of equipment modules. The drawing information 21 is information related to drawings (design documents) of plant equipment modules, and is information that associates drawing numbers, area information, function information, and a BOM (Bill of Materials) list, which is a list of materials used. As shown in FIG. 2, the drawing information 21 includes multiple drawing information records. The drawing information 21 is input from the input unit 10 and stored in the memory unit 20.

[0017] The area information is information about the area where the equipment modules corresponding to the drawing will be installed. The area information illustrated in Fig. 2 indicates that the equipment modules corresponding to the drawing will be installed in Area A (A110, A120), Area B (B110), and Area C (C120).

[0018] Function information is information about the functions possessed by the equipment module corresponding to the drawing. The function information illustrated in Figure 2 indicates that the equipment module corresponding to the drawing has functions U-03 (drainage function) and B-05 (combustion function). If one equipment module has two or more functions, multiple functions are stored as function information in one drawing information record.

[0019] 3 is a diagram showing a piping spool S. A BOM list (material list, parts list) is a list that includes the material codes and quantities of materials used by the equipment module corresponding to the drawing. For example, if the equipment module includes the piping spool S shown in FIG. 3, the BOM list includes the flange B1, elbow B2, straight pipe B3, and olet B4, which are parts that make up the piping spool S.

[0020] The flange B1, elbow B2, straight pipe B3, and olet B4 are not materials exclusive to the piping spool S, but are bulk materials (materials, components) B that can be used for equipment modules other than the piping spool S. The bulk materials B can also be used in the construction of other equipment modules other than the piping spool S, as long as they are of the same type, material, thickness, and size.

[0021] The drawing of the piping spool S may be an ISO drawing, or may be a SPOOL drawing created based on the ISO drawing. The SPOOL drawing is a drawing that specifies the cuts in the piping spool S that will be used for piping spool fabrication (also called "piping spool fabrication"), which connects the bulk materials B together by welding, and describes weld joint numbers, flange joint numbers, etc.

[0022] 4 and 5 are diagrams showing the priority matrix 22. The priority matrix 22 is two-dimensional information used to calculate the priority P of a drawing based on the area information and function information of the drawing information 21. The priority matrix 22 calculates the area priority P based on the area information of the drawing information 21. Ａ The area priority information (FIG. 4) determines the function priority P based on the function information of the drawing information 21. Ｆ and area priority information (FIG. 5) that determines the area priority P Ａ and function priority PＦ The smaller the priority P, the higher the priority. As will be described later, the priority P is determined by the area priority P. Ａ and functional priority P Ｆ The priority matrix 22 is input from the input unit 10 and stored in the storage unit 20.

[0023] The priority weight information 23 is information about weights used when calculating the priority P of the drawings of the equipment modules. The priority weight information 23 is an area weight coefficient W Ａ and the function weight coefficient W Ｆ and the area weighting factor W Ａ is the area priority P Ａ The function weighting coefficient W Ｆ is the function priority P Ｆ The priority weight information 23 is input from the input unit 10 and stored in the storage unit 20.

[0024] The material delivery schedule 24 is information relating to the schedule for delivery of ordered materials. The material delivery schedule 24 is input through the input unit 10 and stored in the storage unit 20. The material delivery schedule 24 is updated to the latest schedule based on shipping information from suppliers, the logistic situation, etc.

[0025] The allocation method selection information 25 is information for selecting an allocation method for allocating materials to be delivered and materials that have already been delivered to equipment modules based on the material delivery schedule 24. The allocation methods include a first allocation method (Max Allocation) and a second allocation method (Booking Allocation). The allocation method selection information 25 is input from the input unit 10 and stored in the memory unit 20.

[0026] The drawing issuance schedule 26 is a drawing issuance schedule determined based on the priority P of the drawings of the equipment modules. The drawing issuance schedule 26 is generated by the priority determination unit 41 of the calculation unit 40 and stored in the storage unit 20.

[0027] The material allocation result 27 is an allocation result of the materials to be delivered and the materials that have already been delivered being allocated to the equipment modules based on the material delivery schedule 24. The material allocation result 27 is generated by the allocation processing unit 42 of the calculation unit 40 and stored in the memory unit 20.

[0028] [Display Unit 30] The display unit 30 is a display device such as a CRT (Cathode Ray Tube) display, a liquid crystal display, an organic EL (Electro Luminescence) display, etc. The operation input unit 11 and the display unit 30 may be a display with a touch panel.

[0029] [Calculation unit 40] The calculation unit 40 is a program-executable computer having a processor such as a CPU and a memory into which a program can be read. The functions of the calculation unit 40 are realized by the processor executing a construction plan management program provided to the calculation unit 40. The calculation unit 40 may have a logic circuit that executes at least some of the calculations of the calculation unit 40.

[0030] The computing unit 40 is not limited to an integrated hardware device. For example, the computing unit 40 may be configured by separating some parts into separate hardware devices and connecting the separated hardware devices via a communication line. For example, the computing unit 40 may be a cloud system in which separated devices are connected via a communication line.

[0031] The calculation unit 40 stores the data acquired from the input unit 10 in the storage unit 20. The data stored in the storage unit 20 is used and updated by the calculation unit 40.

[0032] 6 is a functional block diagram of the calculation unit 40. The calculation unit 40 calculates the future possible construction volume based on the drawing information 21, the material delivery schedule 24, etc. The calculation unit 40 includes a priority determination unit 41, an allocation processing unit 42, and a possible construction volume calculation unit 43.

[0033] [Priority Determination Unit 41] The priority determination unit 41 calculates the priority P of a drawing based on the drawing information 21 of the drawing, and determines the drawing issuance schedule 26 based on the priority P of the drawing.

[0034] The priority determination unit 41 calculates the priority P by applying the priority matrix 22 and the priority weight information 23 to the area information and function information of the drawing information 21. The priority determination unit 41 calculates the priority P based on, for example, the formula shown in Formula 1. In Formula 1, the area priority P Ａ is determined from the area priority information of the priority matrix 22 (FIG. 4) based on the area information. Ｆ is determined from the function priority information of the priority matrix 22 (FIG. 5) based on the function information. Ａ and the function weighting factor W Ｆ is weight information stored as the priority weight information 23, for example, W Ａ +W Ｆ = 1.0.

[0035]

[0036] 7 is a diagram showing the calculated priority P of a drawing. The drawing is classified into one of priority groups PG based on the priority P calculated by the priority determination unit 41. A priority group PG is a collection of drawings having the same priority P (or similar priorities P). The priority P of a drawing shown in FIG. 7 is higher as the priority P number becomes smaller.

[0037] FIG. 8 is a diagram showing the priority weight information 23 adjusted for each construction period. Ａ and the function weight coefficient W Ｆ The area weighting coefficient W can be changed according to the construction period of the plant. For example, as shown in FIG. 8, in the early construction period, the area weighting coefficient W Ａ On the other hand, in the later stages of construction, the functional weighting coefficient W is increased in consideration of the implementation of functional tests. Ｆ Make it bigger.

[0038] The priority determination unit 41 may fix the area weight coefficient Wa to 0.5 and the function weight coefficient Wf to 0.5, for example, without performing weighting using the priority weight information 23. In this case, the priority weight information 23 does not need to be stored in the storage unit 20.

[0039] The priority determination unit 41 determines the drawing issuance schedule 26 based on the priority P of the drawing. For example, the priority determination unit 41 creates a drawing issuance schedule 26 in which the planned issuance date becomes earlier as the priority P of the drawing becomes higher. Note that the priority determination unit 41 may create the drawing issuance schedule 26 taking into consideration other factors besides the priority P of the drawing.

[0040] The priority determination unit 41 stores the priority P of the drawing and the drawing issuance schedule 26 in the storage unit 20 .

[0041] The priority P of the drawing and the drawing issuance schedule 26 do not have to be determined by the priority determination unit 41. For example, the priority P of the drawing and the drawing issuance schedule 26 may be determined by an external system, or may be input by the user via the operation input unit 11.

[0042] [Allocation Processing Unit 42] The allocation processing unit 42 determines a material allocation result 27 in which materials are allocated based on the drawing information 21, the material delivery schedule 24, and the priority P of the drawing. Specifically, when the equipment module is a piping spool S, the allocation processing unit 42 allocates bulk material (material) B, which is scheduled to be delivered according to the material delivery schedule 24, to the piping spool S by referring to the BOM list in the drawing information 21. The allocation processing unit 42 determines a material allocation result 27 in which bulk material (material) B is allocated to the piping spool S based on the allocation method selected in the allocation method selection information 25 and the priority P of the drawing. The allocation methods include a first allocation method (Max Allocation) and a second allocation method (Booking Allocation).

[0043] The drawing information 21 used by the allocation processing unit 42 may not be drawing information of a completely completed and officially issued drawing, but may be drawing information of a drawing in the process of being created. For example, the drawing information 21 may be drawing information of a drawing at the time when the outline of the piping work drawing and the minimum required BOM list have been finalized. This allows the allocation processing unit 42 to determine as much bulk material B required for an equipment module as possible based on the drawing in the process of being created, even if the drawing has not been completely created, and to perform allocation work to determine which equipment module the procured material should be used for.

[0044] 9 to 11 are diagrams illustrating material allocation using the first allocation method. The first allocation method (Max Allocation) is an allocation method that determines a material allocation result 27 so as to maximize the total number of piping spools S (equipment modules) to which all bulk materials B required for each piping spool S are allocated.

[0045] As shown in FIG. 9 , the allocation processing unit 42 allocates bulk material B to a piping spool S used for a drawing belonging to a priority group PG with the highest priority P of "10." The flange B1 has not been delivered and is not available for allocation (Material Available). Therefore, the allocation processing unit 42 allocates all of the required bulk material B to two piping spools S that do not use the flange B1 and for which all of the required bulk material B for each piping spool S is available for allocation (Reservable). The allocation processing unit 42 does not allocate any bulk material B to two piping spools S for which all of the required bulk material B for each piping spool S is not available for allocation.

[0046] 10, the allocation processing unit 42 allocates bulk material B to piping spools S used for drawings belonging to the priority group PG having the next highest priority P of "16." The allocation processing unit 42 allocates all of the required bulk material B to three piping spools S for which all of the required bulk material B is reservable. The allocation processing unit 42 does not allocate any bulk material B to one piping spool S for which all of the required bulk material B is not reservable.

[0047] 11, the allocation processing unit 42 allocates bulk materials B to piping spools S used for drawings belonging to the priority group PG having the next highest priority P of "20." The allocation processing unit 42 allocates all of the necessary bulk materials B to one piping spool S for which all of the necessary bulk materials B are reservable. The allocation processing unit 42 does not allocate any bulk materials B to three piping spools S for which all of the necessary bulk materials B are not reservable.

[0048] After allocation for all priority groups PG is completed, the remaining bulk materials B are allocated sequentially from the piping spools S used for drawings belonging to priority groups PG with higher priorities P. Then, the allocation processing unit 42 calculates the number of bulk materials B (Shotage Materials) that are in short supply.

[0049] 12 to 14 are diagrams illustrating material allocation by the second allocation method. The second allocation method (Booking Allocation) is an allocation method for determining a material allocation result 27 so that a larger amount of bulk material B is allocated to a piping spool S (equipment module) corresponding to a drawing with a higher priority P.

[0050] 12, the allocation processing unit 42 allocates bulk material B to piping spools S used for drawings belonging to a priority group PG having the highest priority P of "10." As in the first allocation method, the allocation processing unit 42 allocates all of the required bulk material B to two piping spools S for which all of the required bulk material B for each piping spool S is reservable. Furthermore, in the second allocation method, the allocation processing unit 42 allocates as much bulk material B as possible to the remaining two piping spools S, even if it is not possible to allocate all of the required bulk material B for each piping spool S.

[0051] 13, the allocation processing unit 42 allocates bulk material B to the piping spools S used for drawings belonging to the priority group PG having the next highest priority P of "16." The allocation processing unit 42 allocates all of the necessary bulk material B to three piping spools S for which all of the necessary bulk material B for each piping spool S is reservable. Furthermore, for the remaining piping spool S, the allocation processing unit 42 allocates as much bulk material B as possible, even if it is not possible to allocate all of the necessary bulk material B for each piping spool S.

[0052] Next, the allocation processing unit 42 allocates bulk materials B to the piping spools S used for drawings that belong to the priority group PG having the next highest priority P of "20," as shown in Fig. 14. Even if the allocation processing unit 42 cannot allocate all of the bulk materials B required for each of the four piping spools S, it allocates as much bulk material B as possible.

[0053] The allocation processing unit 42 calculates the number of bulk materials B (Shotage Materials) that are in short supply.

[0054] 9 to 14, the total number of piping spools S for which all the bulk materials B required for each piping spool S are reservable and workable is 6 in the first allocation method, and 5 in the second allocation method. Material allocation using the first allocation method tends to result in a larger total number of piping spools S for which all the bulk materials B required for each piping spool S are reservable and workable, compared to material allocation using the second allocation method.

[0055] On the other hand, compared to material allocation using the first allocation method, material allocation using the second allocation method tends to allocate more bulk material B to piping spools S used in drawings belonging to priority groups PG with higher priority P.

[0056] The allocation processing unit 42 stores the determined material allocation result 27 in the storage unit 20 .

[0057] [Workable Amount Calculation Unit 43] The workable amount calculation unit 43 calculates the workable amount b3 based on the drawing issuance schedule 26 and the material allocation result 27. The workable amount b3 is calculated from whether the drawings necessary for the construction of the equipment module obtained from the drawing issuance schedule 26 can be completed and whether all materials necessary for the construction of the equipment module obtained from the material allocation result 27 can be allocated. Specifically, if the equipment module is a piping spool S, and if the drawings necessary for the construction of the piping spool S to be constructed are completed at a specified time and all bulk materials (materials) B necessary for the construction of the piping spool S to be constructed are allocated, the piping spool S to be constructed is considered a workable equipment module and is counted in the workable amount b3 (Work front). The workable amount calculation unit 43 calculates the amount of the equipment module that can be constructed for each specified period (e.g., each month) as the workable amount b3.

[0058] Fig. 15 is a construction plan management graph including the possible construction volume. The possible construction volume calculation unit 43 creates a construction plan management graph including the possible construction volume. The construction plan management graph is displayed on the display unit 30. In the construction plan management graph shown in Fig. 15, the horizontal axis is the time axis and the vertical axis is the production volume [inch-dia]. The construction plan management graph shown in Fig. 15 includes performance values ​​such as the actual construction volume for the period up to May 2015.

[0059] The bar graph shown in FIG. 15 shows the planned amount a1 and the actual amount a2 of construction work production (Plan Weld) for the month.

[0060] 15 shows the planned quantity b1 of drawing issuance in the drawing issuance schedule 26, the actual quantity b2 of drawing issuance, the possible construction quantity (Work front) b3, the actually procured quantity b4 of bulk material B among the possible production quantity (Material Allocated) of piping spools (Material Allocated), the quantity b5 of bulk material B actually shipped, the planned quantity b6 of construction production, and the actual construction quantity (Actual Weld) b7. The planned quantity b6 of construction production and the actual construction quantity b7 are line graphs of the totals of the planned quantity a1 of construction production and the construction quantity a2 in the bar graphs described above.

[0061] The user can check the possible construction volume b3 together with the information for calculating the possible construction volume b3. For example, if the planned volume b1 of drawing issuance in the drawing issuance schedule 26 is high on a certain time axis but the possible construction volume b3 is not high, the user can understand that the arrangement of materials (material delivery schedule 24 and material allocation result 27) etc. is not optimized and needs to be improved.

[0062] [Operation of the Construction Plan Management System 1] Next, a description will be given of the operation of the construction plan management system 1. FIG.

[0063] (Step S1: Input Data Acquisition Step) In step S1, the input unit 10 acquires input data (drawing information 21, priority matrix 22, priority weight information 23, material delivery schedule 24, allocation method selection information 25) entered by the user. The calculation unit 40 stores the input data acquired by the input unit 10 in the storage unit 20. The construction plan management system 1 then executes step S2.

[0064] In addition, when the drawing priority P and drawing issuance schedule 26 are input from an external system or input by a user from the operation input unit 11, in step S1, the input unit 10 acquires the drawing priority P and drawing issuance schedule 26 instead of the drawing information 21, the priority matrix 22, and the priority weight information 23.

[0065] (Step S2: Drawing issuance schedule determination step) In step S2, the priority determination unit 41 calculates the priority P of the drawing based on the drawing information 21, the priority matrix 22, and the priority weight information 23, and determines the drawing issuance schedule 26 based on the drawing priority P. The construction plan management system 1 then executes step S3.

[0066] (Step S3: Material Allocation Step) In step S3, the allocation processing unit 42 determines the material allocation result 27 based on the drawing information 21, the material delivery schedule 24, the allocation method selection information 25, and the drawing priority P. The construction plan management system 1 then executes step S4.

[0067] (Step S4: Possible construction quantity calculation step) In step S4, the possible construction quantity calculation unit 43 calculates the possible construction quantity b3 based on the drawing issuance schedule 26 and the material allocation result 27. The construction plan management system 1 then executes step S5.

[0068] (Step S5: Construction plan management graph display step) In step S5, the construction possible amount calculation unit 43 creates a construction plan management graph and displays it on the display unit 30. The construction plan management system 1 then executes step S6.

[0069] (Step S6: Evaluation acquisition step) In step S6, the input unit 10 acquires the user's evaluation of the possible construction amount b3 of the construction plan management graph presented to the user. If the user's evaluation of the possible construction amount b3 is a positive evaluation, the construction plan management system 1 ends the control flow. If the user's evaluation of the possible construction amount b3 is a negative evaluation, the construction plan management system 1 executes step S1 again.

[0070] (Step S1: Input Data Update Step) In step S1, the input unit 10 acquires at least partially updated input data from the user. The user updates the input data (drawing information 21, priority matrix 22, priority weight information 23, material delivery schedule 24, and allocation method selection information 25) in order to improve the possible construction volume b3.

[0071] For example, in order to change the priority P of the drawing and the drawing issuance schedule 26, the user may update the priority matrix 22 and the priority weight information 23. For example, if a customer requests that a part of an area be handed over and put into operation earlier than originally planned during the construction process, the user may update the area priority P of the area. Ａ and area weighting coefficient W Ａ The priority matrix 22 and the priority weight information 23 may be updated so that the priority P of the drawing and the drawing issuance schedule 26 that have been changed in response to the update of the input data are used to recalculate the material allocation result 27 and the possible construction amount b3.

[0072] For example, in order to change the material allocation result 27, the user may update the material delivery schedule 24 or the allocation method selection information 25. For example, the user updates the material delivery schedule 24 by changing the transportation method for materials that are causing a bottleneck in the available construction volume b3 due to an insufficient allocated volume in the construction plan management graph presented in step S6 from sea freight (maritime transport) to air transport. The construction plan management system 1 recalculates the available construction volume b3 using the material delivery schedule 24 and allocation method selection information 25 that have been changed in response to the update of the input data.

[0073] The user checks the construction plan management graph that has been regenerated based on the updated input data (drawing information 21, priority matrix 22, priority weight information 23, material delivery schedule 24, and allocation method selection information 25). The user can repeatedly update the input data and check the construction plan management graph until a sufficient construction feasibility amount b3 is obtained. This allows the construction plan management system 1 to optimize the drawing issuance schedule 26 and material arrangements (material delivery schedule 24 and material allocation result 27) so as to ensure a sufficient construction feasibility amount b3.

[0074] The construction plan management system 1 according to this embodiment manages the drawing issuance schedule 26 and material procurement schedules (material delivery schedule 24 and material allocation results 27). Even if the drawings are not yet fully created, the system determines the materials needed for an equipment module based on the drawings being created, and allocates the procured materials to each equipment module, thereby determining the future construction availability b3. The construction plan management system 1 recalculates the construction availability b3 and presents a construction plan management graph as the input data (drawing information 21, priority matrix 22, priority weight information 23, material delivery schedule 24, and allocation method selection information 25) is updated. This allows the user to optimize the input data (drawing information 21, priority matrix 22, priority weight information 23, material delivery schedule 24, and allocation method selection information 25) to ensure a sufficient construction availability b3.

[0075] While one embodiment of the present disclosure has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment and includes design modifications within the scope of the present disclosure. Furthermore, the components shown in the above embodiment and the modified examples shown below can be configured by appropriately combining them.

[0076] (Variation) The construction plan management system of the present disclosure is not limited to systems that manage and adjust construction plans for large-scale plants, but can also be applied to systems that manage production plans for equipment modules that require drawings and materials.
