The home design page is configured to allow a user to create a floor plan by arranging rooms, etc. as desired using a mouse, etc., and to display a total price (total cost required to construct a building) according to the floor plan. The total price is calculated by adding up the individual prices of the rooms, etc. and the construction cost of the main body of the home.

[0004] In the system of Patent Document 1, the total price is calculated roughly based on the area of ​​the room in which the user has placed the items, so there is a possibility that the total price cannot be calculated accurately. This leaves room for improvement. [Prior art documents] [Patent documents]

[0026] A calculation system 1 according to an embodiment of the present invention will be described below.

[0027] The calculation system 1 shown in FIG. 1 is for calculating the total cost and total lead time of a building at the stage when the design of the building is finalized. The total cost is the cost required for building the building (see total costs A51 to A53 shown in FIG. 12). The total cost is the sum of the cost required for work in the factory and the cost required for work on site. The above-mentioned "work" includes various work such as assembly work and transportation work. The total lead time is the period from the start of construction of the building to the end of construction (see total lead times B51 to B53 shown in FIG. 12). More specifically, the total lead time is the period from the start of work in the factory to the end of work on site. The total lead time includes the lead time required for work in the factory and the lead time required for work on site. The calculation system 1 will be specifically described below.

[0028] The calculation system 1 is composed of a plurality of PCs each having a calculation device capable of executing calculation processing, a storage device storing programs and the like, an input device capable of inputting information, and an output device capable of displaying the results of calculation processing and the like. For the sake of convenience of explanation, in the drawings, the hardware configuration of the calculation system 1 is omitted, and only the software configuration (e.g., design unit 10, etc.) is described. The configuration of the calculation system 1 will be described below with reference to Figs. 1 to 6. The calculation system 1 comprises a design unit 10, a part calculation unit 20, a structure calculation unit 30, and a general information calculation unit 40.

[0029] The design unit 10 is for designing a building. The design unit 10 is configured to be able to input design information and the like to a structure calculation unit 30, which will be described later. The design unit 10 includes a construction model library 11.

[0030] The construction model library 11 is used to design buildings on a PC. The construction model library 11 includes a group of Building Information Modeling (BIM) models consisting of multiple BIM models. A BIM model is a three-dimensional model of a building that can be displayed on a PC. The multiple BIM models are models that differ from each other in terms of building construction methods (what materials are used to construct the entire building structure and how they are assembled), etc. In the construction model library 11, parameters related to the design of a building can be input.

[0031] The parameters related to the design of a building are values ​​necessary for designing a building. The parameters include, for example, the construction method of the building, the dimensions and materials of various members such as columns, and the area in which the building is to be constructed. The construction model library 11 can extract one BIM model (a model of a building) based on input parameters (construction method, etc.) from among multiple BIM models, and change the shape of the extracted BIM model according to the input parameters (dimensions, etc.). In this way, the construction model library 11 can design a building while changing the three-dimensional shape of the building in real time (parametrically designing) by inputting parameters. In addition, the parameters are appropriately changed according to, for example, customer requests. In this way, the construction model library 11 can design buildings with different shapes, etc. for each customer.

[0032] Hereinafter, the 3D shape of the building with a finalized design (obtained by inputting the finalized parameters into the construction model library 11) is referred to as the "planning and design model A11." With the planning and design model A11 (see FIG. 8), the 3D shape of the building and the rough relationships between various components (for example, that the framework is a combination of beams, columns, etc.) can be grasped, but it is difficult to grasp the detailed relationships between the various components (for example, the parent-child relationships broken down to the unit of a single part).

[0033] The part calculation unit 20 is for outputting detailed relationships between various members. The part calculation unit 20 includes a manufacturing model library 21.

[0034] The manufacturing model library 21 generates a part model A21 (see FIG. 8). The part model A21 is information (information showing details of a building) in which the parent-child relationships of various components are broken down into units of a single part. The manufacturing model library 21 includes a part group (information that is the source of the part model A21) that pairs with the BIM model group in the construction model library 11. The manufacturing model library 21 can generate the part model A21 by performing a predetermined calculation process using the information (e.g., construction method) and the part group inputted to the construction model library 11.

[0035] The part calculation unit 20 configured as described above receives predetermined information (e.g., construction method, etc.) from the design unit 10 (construction model library 11). The part calculation unit 20 can output a part model A21 (part model A21 corresponding to the designed building) obtained by inputting the input information to the manufacturing model library 21. The part calculation unit 20 is configured to be able to input the output result of the part model A21 to the structure calculation unit 30.

[0036] The structure calculation unit 30 cooperates with the design unit 10 and the component calculation unit 20 to calculate a product structure A31 (see FIG. 3, hereafter referred to as the "residence-specific structure A31") for each residence (customer), the contents of which vary for each residence. The residence-specific structure A31 is information that breaks down the various components used in a building whose design has been finalized by the design unit 10 (information that physically classifies columns, beams, etc.). The residence-specific structure A31 is also information that shows in stages the parent-child relationships of the various components (what combinations of components make up the building).

[0037] Specifically, as shown in Fig. 3, the house structure A31 has a tree structure with the building at the top level. As will be described later, the house structure A31 reflects information from the part model A21, so various components (e.g., pillars, etc.) used in the building are broken down into individual components and displayed in stages. For some components, even the material is displayed.

[0038] The structure calculation unit 30 includes a product structure model 31 as shown in FIG.

[0039] The product structure template 31 (hereinafter referred to as "template 31") shown in Figures 1 and 2 is the basis for the residence-specific structure A31. The template 31 is composed of a group of tables managed by a DBMS (Database Management System), for example. The template 31 is prepared before the design of the building is finalized (in advance). Also, multiple templates 31 are prepared according to the construction method and region of the building, etc.

[0040] Specifically, the work content when constructing a building varies depending on the construction method, region, etc. For example, when a building is constructed using a steel frame unit construction method or in an area where it is easy to transport large components, there is a tendency to manufacture most of the components in a factory and transport them to the site. On the other hand, when a building is constructed in an area where it is difficult to transport large components, there is a tendency to transport small components to the site and assemble them. In order to match the work content according to such construction methods and regions, a template 31 is prepared in which nodes 31a and lines 31c, which will be described later, are appropriately determined (see Figs. 13 to 16). In the following, the configuration of the template 31 (strictly speaking, information on the tree structure managed by the DBMS) will be described using the template 31 shown in Fig. 2 as an example. The template 31 includes nodes 31a, branches 31b, and lines 31c.

[0041] Node 31a stores identification information (for example, a character string such as "foundation") of various components that make up a building. Nodes 31a are arranged in stages according to the parent-child relationships of the various components of the building. Of the nodes 31a, the "Building" node 31a is arranged at the highest level. In the drawing, the information (identification information, etc.) stored in node 31a is appropriately written within the frame of node 31a.

[0042] The branch 31b connects the upper node 31a and the lower node 31a.

[0043] The line 31c is for defining the relationship between the work place (the place where the work included in the construction work indicated by the work type is performed, for example, the site or factory) and the node 31a according to the type of work of the building. The line 31c shown in FIG. 2 is arranged to cross the branch 31b that connects the upper "structure" node 31a with the lower "column" node 31a and "beam" node 31a. In this way, the work place of the "structure" node 31a above the line 31c is defined as the site, and the work place of the "column" node 31a below the line 31c is defined as the factory. In this way, the line 31c can define, for example, how far various components are assembled in the factory and shipped to the site (shipping line). Such delineation is also performed in the "foundation" node 31a and the "wall" node 31a at the same level as the "structure" node 31a, but their description is omitted in FIG. 2. In FIG. 2, nodes 31a, branches 31b, and lines 31c are visualized, but in reality, the identification information of various components, the parent-child relationships, and the identification information of the work locations are stored in association with each other so that the parent-child relationships of various components and the work locations are as shown in FIG.

[0044] The template 31 configured as described above is prepared at a stage before the design is finalized. At the stage before the design is finalized, some specifications have not been determined. For this reason, abstract information is stored in the template 31 for parts whose specifications have not been determined. For example, the material of the timber has not been determined at a stage before the design is finalized, so the character string "material" is stored in the node 31a subordinate to the "timber" node 31a.

[0045] The structure calculation unit 30 configured as described above can calculate the individual residence structure A31 by reflecting the determined specifications in the template 31. The flow of calculating the individual residence structure A31 will be described later.

[0046] The general information calculation unit 40 shown in Fig. 1 is for calculating the total cost and total lead time of a building whose design has been finalized. The general information calculation unit 40 includes a manufacturing calculation information DB 41, a construction calculation information DB 42, a manufacturing and construction component library 43, a work type component library 44, a manufacturing and construction work type DB 45, constraint information 46, and a placement unit 47.

[0047] The manufacturing calculation information DB41 and the construction calculation information DB42 store information required for calculating the cost A44 and the lead time B44 (the cost and the lead time required for the construction indicated by the construction type, see FIG. 5(b)) according to the type of work for each work location. The manufacturing calculation information DB41 and the construction calculation information DB42 are composed of tables managed by the DBMS.

[0048] The manufacturing calculation information DB 41 stores information on fixed values ​​(real numbers) required to calculate the cost A 44 and lead time B 44 required for work performed in a factory among the work included in the work type. The manufacturing calculation information DB 41 stores information such as the unit price of parts, the cost and lead time per unit of work, and the transportation cost and transportation lead time per unit of parts from a supplier (supplier of parts) to the factory.

[0049] The construction calculation information DB 42 stores information on fixed values ​​required for calculating the cost A44 and lead time B44 required for work performed on-site among the work included in the work type. The construction calculation information DB 42 stores information such as the unit price of materials, the cost and lead time per unit work, and the transportation cost and transportation lead time per unit material from the supplier or factory to the site.

[0050] The manufacturing and construction component library 43 shown in Fig. 1 and Fig. 4 calculates the cost A43 and lead time B43 required for work included in a type of work (for example, transportation and assembly work of individual materials and parts). Note that a component refers to a function that performs a predetermined calculation process on input values ​​and outputs the results. The manufacturing and construction component library 43 includes multiple manufacturing and construction components 43a.

[0051] The manufacturing and construction component 43a calculates the cost A43 and lead time B43 of one of the tasks included in the work type. Multiple manufacturing and construction components 43a are implemented for each task content and work location. For example, to calculate the cost A43 required for procuring a specific part, a manufacturing and construction component 43a for procuring at a factory (see "procure at factory" in FIG. 4(a)) and a manufacturing and construction component 43a for procuring at a site (see "procure at site" in FIG. 4(a)) are implemented.

[0052] As shown in Fig. 4(b), information related to the work (for example, the "area" where the work is performed and the "material name / symbol" that identifies the material used in the work, see data D) is input to the manufacturing and construction component 43a. The manufacturing and construction component 43a performs calculation processing using the input information, thereby calculating (outputting) the cost A43 and lead time B43 required for the work.

[0053] The work type component library 44 shown in Figures 1 and 5 is for calculating the cost A44 and lead time B44 according to the work type. The cost A44 according to the work type is the sum of the costs A43 required for multiple tasks included in the work type. The lead time B44 according to the work type is the sum of the lead times B43 required for multiple tasks included in the work type.

[0054] Here, the work included in the work type may have different work locations depending on the construction method, region, etc. For example, the processing work of the components may be performed in a factory, and the assembly work of the components may be performed on-site. The work type component library 44 includes a plurality of work type components 44a capable of calculating the cost A44 and the lead time B44 for each of such factories and sites (work locations). The plurality of work type components 44a are implemented for each work type, factory, and site. For example, as a calculation of the cost A44 of foundation work, a work type component 44a (see "foundation work (site)" shown in FIG. 5(a)) that calculates the cost A44 required for work on-site and a work type component 44a (see "foundation work (factory)" shown in FIG. 5(a)) that calculates the cost A44 required for work in the factory are implemented.

[0055] As shown in FIG. 5(b), information about the work type (for example, the "area" where the work type is to be performed and the "material name / symbol" that identifies the materials used in the work type, etc.) and information about the manufacturing and construction component 43a ("component data") are input to the work type component 44a (see data D). Note that the information about the manufacturing and construction component 43a is information for calculating the cost A43 of some of the tasks included in the work type using the manufacturing and construction component 43a. The information about the manufacturing and construction component 43a includes, for example, identification information for the manufacturing and construction component 43a and values ​​to be input to the manufacturing and construction component 43a.

[0056] The work type component 44a can calculate the cost A44 and the lead time B44 according to the work type by performing calculation processing using the input information. At this time, as shown in Fig. 6, the work type component 44a calculates the cost A44, etc. using information stored in the manufacturing calculation information DB 41, the input manufacturing and construction component 43a, and a component 44b different from the component 43a.

[0057] In addition, the work type component 44a calculates not only the cost A43 and lead time B43 for the first work (e.g., transporting materials and assembling materials) for creating the shape of the building, but also the cost A43 and lead time B43 for the second work (e.g., scaffolding, cleaning, and other work incidental to the work) that does not create the shape of the building. The work type component 44a calculates the cost A44 according to the work type by taking into account the calculation results of the cost A43 of such second work. For example, the calculation results of the cost A43 of the first work and the cost A43 of the second work are added together to calculate the cost A44 according to the work type.

[0058] The manufacturing and construction work type DB 45 shown in Fig. 1 and Fig. 7 is information that breaks down the types of work required for building a building (information about conceptual things that have no substance). The manufacturing and construction work type DB 45 is information that shows the types of work and work locations in stages. The manufacturing and construction work type DB 45 is stored in a group of tables managed by the DBMS. The manufacturing and construction work type DB 45 has a root 45a, a child node 45b, and a grandchild node 45c.

[0059] The root 45a is the highest node in the manufacturing and construction type DB. The root 45a stores identification information of the construction method of the building (in FIG. 7, "precut / preset") and the like.

[0060] The child node 45b is a node located at one level below the root 45a. The child node 45b stores identification information of the type of work (for example, "foundation work" and "construction work"). A plurality of child nodes 45b are arranged according to the construction method.

[0061] The grandchild node 45c is a node located one level below the child node 45b. A plurality of grandchild nodes 45c (the same number as the work locations, two in FIG. 7) are connected to one child node 45b. The grandchild node 45c appropriately stores information for calculating the cost A44 and the like according to the work type indicated by the child node 45b in the work type component 44a.

[0062] Specifically, the grandchild node 45c stores, for example, identification information of the work location (such as "site"), identification information of the work type component 44a corresponding to the work location (the "work type (site) component" that calculates the on-site cost A44 of the construction work, etc.), and identification information of the manufacturing and construction component 43a input to the work type component 44a.

[0063] In addition, the grandchild node 45c stores identification information of the manufacturing calculation information DB 41 or the construction calculation information DB 42 depending on the work location. Specifically, the "factory" node 45c stores identification information of the manufacturing calculation information DB 41 that stores fixed values ​​for work in the factory. In addition, the "site" node 45c stores identification information of the construction calculation information DB 42 that stores fixed values ​​for work on the site.

[0064] In this manner, in the grandchild node 45c, the manufacturing calculation information DB 41, the work type component 44a, etc. are appropriately associated and stored according to the work type and the work location.

[0065] The manufacturing construction type DB 45 configured as described above is prepared in advance as a plurality of DBs according to the construction method, region, etc. Specifically, as described above, the work content differs according to the construction method, region, etc. Depending on the difference in the work content, the information to be stored in the grandchild node 45c (values ​​to be input to the work type component 44a) also changes. Therefore, the manufacturing construction type DB 45 is prepared as a plurality of DBs in which information is appropriately stored in the grandchild node 45c so as to match the work content according to the construction method, region, etc. In addition, the information of the grandchild node 45c of the DB is appropriately determined based on the line 31c (see FIG. 2) of the template 31 determined according to the construction method, region, etc. In this way, the manufacturing construction type DB 45 and the template 31 are provided to be paired with each other.

[0066] 1 is information on constraints to be considered when creating schedules 51 to 5N (see FIG. 12). The constraint information 46 includes, for example, the order in which construction types are performed, capacity, and customer requests (for example, requests regarding the timing of starting construction of a building, etc.). The constraint information 46 is set in advance (before the design is finalized).

[0067] The arrangement unit 47 is for creating schedules 51-5N in which work types are arranged in chronological order. The arrangement unit 47 is configured with a program that can be run on a PC, etc. The arrangement unit 47 can read information stored in the constraint information 46 and create multiple schedules 51-5N in which work types are arranged differently.

[0068] The overall information calculation unit 40 configured as described above is configured to be able to change (add, update, and delete) the information in the manufacturing and construction type DB 45. In addition, the overall information calculation unit 40 is configured to be able to calculate the total cost and the total lead time using the information in the manufacturing and construction type DB 45 and the schedules 51 to 5N.

[0069] The calculation process by the calculation system 1 will be described below with reference to Fig. 2, Fig. 3, and Fig. 8 to Fig. 12. Note that "1" to "8" shown in Fig. 8, Fig. 9, and Fig. 11 indicate the order of the calculation process. Also, "0" indicates that it has been prepared in advance.

[0070] The calculation process is a process for calculating the individual house structure A31, the total cost, and the total lead time. The calculation process is appropriately executed after the design of the building is completed in the construction model library 11 shown in Fig. 8. When the calculation process is started, the construction model library 11 generates a planning and design model A11 (a model of the building obtained by inputting parameters into the construction model library 11) (see process "1" in Fig. 8).

[0071] The planning and design model A11 holds summary information that indicates an overview of the designed building. The summary information includes information required to display the three-dimensional shape of the building on a PC and information (metadata) attached to various components. Specifically, the summary information includes, for example, three-dimensional shape information of various components of the building (three-dimensional coordinates of the foundation and framework, etc.), information indicating the materials of the various components, the construction method of the building, the region, parameters entered into the construction model library 11, etc. In this way, the summary information is information (design information) designed by the design unit 10.

[0072] When the planning and design model A11 is generated, the design unit 10 inputs the outline information held by the planning and design model A11 to the manufacturing model library 21 (see the process "2" in FIG. 8).

[0073] The manufacturing model library 21 outputs a part model A21 (information indicating details of the building) based on the input outline information (see process "3" in FIG. 8).

[0074] When the manufacturing model library 21 outputs the part model A21, the design unit 10 and the part calculation unit 20 input the summary information (planning and design model A11) and the part model A21 (detailed information) to the structure calculation unit 30. The structure calculation unit 30 inputs the input information to the template 31 (see process "4" in FIG. 8). Specifically, the structure calculation unit 30 extracts one template 31 from the templates 31 according to the construction method and region, etc., included in the summary information. Then, the structure calculation unit 30 reflects the summary information and the contents of the part model A21 in the extracted template 31.

[0075] For example, when the template 31 shown in Fig. 2 is extracted from the construction method and region, the structure calculation unit 30 reflects information about the confirmed design in the template 31. Specifically, the structure calculation unit 30 reflects, for example, the quantity of pillars and pre-cut lumber, the dimensions of the square pillars, and the fact that the material of the square pillars is "cedar" and "cypress." In this way, as shown in Figs. 3 and 8, the structure calculation unit 30 calculates a residence-specific structure A31 based on the template 31 (see process "5" in Fig. 8).

[0076] In this way, the structure calculation unit 30 calculates detailed information from the summary information obtained in the design (planning and design model A11) by the design unit 10 (processing of "3"), and calculates the individual residence structure A31 by aggregating the summary information and detailed information (processing of "4" and "5"). In this way, the structure calculation unit 30 can calculate the individual residence structure A31 at the stage when the design of the building is completed.

[0077] When the structure calculation unit 30 calculates the individual house structure A31, the general information calculation unit 40 associates the information of the individual house structure A31 with the work type component 44a, etc., and stores it in the manufacturing and construction work type DB 45, as shown in Figures 9 and 10 (see process "6" in Figure 9). Specifically, the general information calculation unit 40 extracts the manufacturing and construction work type DB 45 paired with the template 31 that is the basis of the individual house structure A31.

[0078] In the grandchild node 45c of the manufacturing construction type DB45 thus extracted, the manufacturing calculation information DB41 and the type of work component 44a, etc. are appropriately associated and stored according to the line 31c. Specifically, for example, when the template 31 shown in FIG. 10 is specified from the construction method and region, since the "column" node 31a and the "beam" node 31a, etc. are located below the line 31c, the columns and beams of the framework will be manufactured in a factory. In the "factory" node 45c shown in FIG. 10, the type of work component 44a, the manufacturing calculation information DB41, the manufacturing construction component 43a, etc. are previously associated and stored so as to calculate the cost A44 and the lead time B44 required for the manufacturing work in such a factory. However, at the time when the manufacturing construction type DB45 is extracted, the information on the confirmed design (for example, the number of columns and materials, etc.) is insufficient, so that the cost A44 required for manufacturing the columns and beams, etc. cannot be calculated.

[0079] Therefore, the general information calculation unit 40 inputs information on the individual residence structure A31 to the grandchild node 45c according to the line 31c (rule) and adds information that is missing for the calculation of the cost A44, etc. For example, the general information calculation unit 40 inputs the number of columns, materials, etc. to the "factory" node 45c shown in Fig. 10. In this way, the information on the finalized design is reflected in the "factory" node 45c, and the grandchild node 45c (work type component 44a) can calculate the cost A44, etc. according to the work type.

[0080] As shown in Fig. 9, when the general information calculation unit 40 inputs information into the manufacturing and construction type DB 45, it calculates the cost A44 and the lead time B44 according to the type of work (see process "7" in Fig. 9). At this time, the general information calculation unit 40 calculates the cost A44 and the like for each work location (factory and site) using the type of work component 44a stored in the grandchild node 45c.

[0081] As shown in Figures 11 and 12, when the general information calculation unit 40 calculates the cost A44 and the lead time B44, the arrangement unit 47 creates a schedule in which the work types are arranged in chronological order. At this time, the arrangement unit 47 creates multiple schedules with different arrangements of work types, and narrows down some of the schedules to present to the customer. In this way, by presenting a certain number of schedules rather than all schedules that can be created, it becomes easier for the customer to select the schedule they want.

[0082] When the general information calculation unit 40 calculates the cost A44, etc., the arrangement unit 47 creates multiple schedules 51 to 5N based on the calculation result of the lead time B44 and the constraint information 46. At this time, the arrangement unit 47 creates multiple schedules 51 to 5N with different arrangements of work types so that there is no contradiction in the order of the work types (constraint information 46) and the work types can be performed within the capacity (constraint information 46). In addition, the arrangement unit 47 creates the schedules 51 to 5N according to the customer's request (for example, request such as the start time of construction work, constraint information 46). The schedules 51 to 5N created in this way may be too many in number depending on the content of the constraint information 46. In this case, it may be a burden for the customer to select a schedule. For this reason, the schedules 51 to 5N are narrowed down in the following procedure.

[0083] First, the general information calculation unit 40 calculates information for narrowing down the schedules 51 to 5N. Specifically, it calculates the total lead time and the total cost when constructing a building according to the schedules 51 to 5N. At this time, the general information calculation unit 40 calculates the period from the start of the first type of work to the end of the last type of work, and sets the calculation result as the total lead time (see total lead times B51 to B53 shown in FIG. 12). This allows the general information calculation unit 40 to accurately determine the total lead time based on the arrangement of the types of work.

[0084] The general information calculation unit 40 also calculates the total cost by adding up the calculation results of the cost A44 according to the type of work (see total costs A51 to A53 shown in FIG. 12). The general information calculation unit 40 may recalculate the cost A44 of each type of work according to the type of work arranged in the schedule 51 to 5N to calculate the total cost. In this case, the general information calculation unit 40 determines whether the work can be performed together (for example, whether materials can be transported together) for multiple types of work whose work is performed at the same time in the schedule 51 to 5N. If the work can be performed together, the general information calculation unit 40 recalculates the cost A44 for the combined work and reflects the recalculation result in the total cost. This allows the general information calculation unit 40 to accurately determine the total cost by taking into account the timing of the work.

[0085] When the general information calculation unit 40 calculates the total cost, etc., the allocation unit 47 narrows down the schedules 51 to 5N (see process "8" in FIG. 11). At this time, the allocation unit 47 evaluates the calculation results of the total cost, etc. using evaluation indices (for example, thresholds of the total cost and total lead time, customer requests such as a desire to finish the work quickly, etc.). Then, the allocation unit 47 extracts some of the schedules 51 to 5N in which the work types are considered to be appropriately allocated. Note that in FIG. 11, three schedules 51 to 53 shown in FIG. 12 are extracted. In this way, the allocation unit 47 narrows down the schedules 51 to 5N.

[0086] The narrowed-down process schedules 51-53 are displayed on a PC and presented to the customer. In addition, the calculation results of total costs A51-A53 and total lead times B51-B53 corresponding to the process schedules 51-53 are also presented to the customer for each process schedule 51-53. With this configuration, the customer can arbitrarily select a process schedule 51-53, improving convenience. Also, the optimal process schedule can be selected in accordance with the customer's requests, etc. When the customer selects one process schedule, the calculation process ends.

[0087] If the presented schedules 51 to 53 do not contain the one the customer desires to select, for example, the design of the building is partially changed (the parameters to be input to the construction model library 11 are partially changed). The structure calculation unit 30 calculates a per-house structure A31 with different contents from the previous time in accordance with the changed contents. The placement unit 47 also presents a schedule with different contents from the previous time. Such re-presentation of schedules can be repeatedly executed until the customer selects a schedule.

[0088] In this way, in the calculation system 1 according to this embodiment, the individual house structure A31 can be obtained at the stage when the design of the building is finalized in the construction model library 11 (see FIG. 8). This allows the parent-child relationships of the various components of the building to be grasped in detail (down to the component level) at the stage when the design is finalized. Therefore, the overall information calculation unit 40 can quickly and accurately calculate the total costs A51-A53 and the total lead times B51-B53.

[0089] In addition, in the individual house structure A31, the work location is specified for each type of component (see FIG. 10). This allows the difference in cost and lead time according to the work location to be reflected in the total costs A51-A53 and the total lead times B51-B53. This allows the general information calculation unit 40 to more accurately calculate the total costs A51-A53 and the total lead times B51-B53.

[0090] In addition, the work type component 44a is configured to be able to reflect the cost A43 and lead time B43 required for work incidental to the work type (such as scaffolding assembly work) in the cost A44 and lead time B44 corresponding to the work type. This makes it possible to more accurately calculate the total costs A51 to A53 and the total lead times B51 to B53.

[0091] In addition, the manufacturing calculation information DB41 and the work type component 44a are stored in association with the grandchild node 45c of the manufacturing and construction work type DB45 according to the work type and the work location. With this configuration, the cost A44 and the lead time B44 of the work type can be easily calculated by simply reflecting the information on the confirmed design (information on materials included in the individual structure A31) in the grandchild node 45c.

[0092] A specific example of the calculation process by the manufacturing and construction component 43a will be described below with reference to Fig. 4. Note that the specific example will be described below with reference to the case where the cost A43 and the lead time B43 required for procuring parts are calculated from the data D shown in Fig. 4(b).

[0093] The cost A43 required for procuring parts includes the cost of purchasing parts from a supplier and the cost of shipping the parts. When calculating the cost A43, the manufacturing and construction component 43a determines a supplier from the input "region" and "part name / symbol". The manufacturing and construction component 43a uses the determined supplier as a key to obtain the part unit price, delivery unit price, and delivery lead time per unit from the manufacturing calculation information DB41. The manufacturing and construction component 43a then multiplies the part unit price by the "part quantity" to calculate the part purchase cost, and multiplies the delivery unit price by the "part quantity" to calculate the part delivery cost. The manufacturing and construction component 43a adds up the calculation results of these costs to calculate the part procurement cost A43.

[0094] When calculating the lead time B43 required for procuring parts, the manufacturing and construction component 43a calculates the number of trucks from the "parts name / symbol" and "parts quantity", and calculates the delivery lead time for one truck based on the "delivery destination". The manufacturing and construction component 43a then multiplies the calculated results of the number of trucks and the delivery lead time to calculate the lead time B43 required for procuring parts.

[0095] A specific example of the calculation process by the work type component 44a will be described below with reference to Fig. 5. Note that, in the following, a specific example will be described by taking as an example a case where a cost A44 and a lead time B44 required for construction work are calculated from the data D shown in Fig. 5(b).

[0096] The cost A44 required for the construction work includes the delivery cost of delivering all the materials used in the construction work, the construction cost (labor cost) required for the construction of the construction work, and the costs incidental to the construction work (for example, the cost required for cleaning, etc.). When calculating the cost A44, the work type component 44a receives information ("component data") of the manufacturing and construction component 43a that can calculate some of the costs included in the cost A44. In this way, the work type component 44a can calculate the cost of some of the work required for the construction work using the manufacturing and construction component 43a. The work type component 44a calculates the cost of work that cannot be calculated by the manufacturing and construction component 43a based on the input results of "area" and the like. For example, the delivery cost of delivering all the materials and the construction cost required for construction are calculated.

[0097] Specifically, the work type component 44a identifies all components to be delivered to the site from the "component name / symbol" and "component data." The work type component 44a acquires the delivery cost from the construction calculation information DB 42 using the "delivery destination" and the delivery origin (factory or supplier) as keys. The work type component 44a calculates the delivery cost from the "component quantity."

[0098] Moreover, the work type component 44a acquires the construction labor cost from the construction calculation information DB 42 using the "area" as a key, and calculates the construction cost from the acquired result and the "quantity of components."

[0099] The work type component 44a calculates the cost A44 required for the construction work by adding up the delivery cost and construction cost thus calculated and the cost A43 calculated using the manufacturing and construction component 43a.

[0100] Moreover, when calculating the lead time B44 required for construction work, the work type component 44a calculates the lead time B43 of some work using the manufacturing and construction component 43a, as in the case of the cost A44. The work type component 44a also calculates the lead time of work that cannot be calculated by the manufacturing and construction component 43a based on the input results of "area" etc.

[0101] In this way, the work type component 44a calculates the cost A44 of the work type using the manufacturing and construction component 43a. This makes it possible to calculate the cost of the same work for different work types using the common manufacturing and construction component 43a, thereby reducing the burden of implementing the work type component 44a. Furthermore, if the calculation method for the cost A43 of a certain task changes, the change can be reflected in multiple work type components 44a by changing the content of the calculation process of one manufacturing and construction component 43a corresponding to that task. This also reduces the burden of maintenance work.

[0102] A specific example of the template 31 will be described below with reference to FIGS.

[0103] As described above, a plurality of templates 31 are prepared according to the construction method and region of the building, etc. Figs. 13 to 16 show an example of such a template 31.

[0104] Specifically, the template 31 shown in Figs. 13 and 14 is a diagram showing an example of a template when a building is constructed by a steel frame unit construction method in which most of the building is completed in a factory and assembled on-site. The template 31 shown in Fig. 13 is an example of a template when a building is constructed overseas. Moreover, the template 31 shown in Fig. 14 is an example of a template when a building is constructed in a suburban area of ​​Japan. As shown in Figs. 13 and 14, when the construction method is the same but the region is different, multiple templates 31 are prepared in which the arrangement of nodes 31a is the same but the settings of lines 31c are different. Moreover, the lines 31c shown in Figs. 13 and 14 are set according to the local conditions (for example, traffic conditions and building laws and regulations).

[0105] Specifically, overseas, there are relatively few traffic conditions that prevent the transportation of components (for example, roads are narrow and large trucks cannot reach the site) and restrictions such as laws and regulations, so there is a tendency to manufacture a certain amount of materials in factories and transport large manufactured products to the site for assembly. For this reason, as shown in Figure 13, line 31c for constructing a building overseas using the steel frame unit construction method is arranged to cross the top "building" node 31a and the next lower "foundation" node 31a and "unit" node 31a. Note that it is assumed that the foundation will be PCa foundation (foundation manufactured in a factory).

[0106] On the other hand, in the suburbs of Japan, where traffic conditions and legal regulations are more restrictive than overseas, it is considered desirable to manufacture small unit frames and panels in a factory and assemble them on-site. For this reason, as shown in Figure 14, the line 31c for constructing a building in the suburbs of Japan using the steel frame unit construction method is arranged to cross between the "unit" node 31a and the "frame" node 31a and the "panel" node 31a.

[0107] In addition, in domestic city centers, it is considered difficult to construct buildings using the steel unit construction method due to traffic conditions and other reasons. For this reason, no templates have been prepared for building buildings in domestic city centers using the steel unit construction method. Furthermore, the construction model library 11 (see Figure 8) is configured so that the steel unit construction method cannot be input when designing a building to be constructed in domestic city centers.

[0108] By preparing a template 31 as shown in Figures 13 and 14, the work locations for each type of construction work when constructing a building overseas or in the suburbs of Japan using the steel unit construction method can be appropriately specified at the stage when the design is finalized.

[0109] The template 31 shown in FIG. 15 is a diagram showing an example of a template 31 for constructing a building using a wooden panel construction method in which wooden panels used for structural members such as floors and walls are manufactured in a factory and assembled on-site. When constructing a building using the wooden panel construction method, three templates 31 are prepared corresponding to overseas, suburban areas in Japan, and urban areas in Japan. The three templates 31 have the same arrangement of nodes 31a but different settings of lines 31c. FIG. 15 shows lines 31c for the three templates 31. The lines 31c are set according to local circumstances, etc.

[0110] More specifically, when a building is constructed overseas using a wooden panel construction method, the line 31c is arranged on the assumption that, as with the steel frame unit construction method, the products will be manufactured in a factory to a certain extent and then transported to the site for assembly. Specifically, as shown by the solid line in Fig. 15, when a building is constructed overseas using a wooden panel construction method, the line 31c is arranged to cross the top "Building" node 31a and the "Foundation" node 31a and "Panel" node 31a one level lower. Also, the line 31c is arranged to cross the "Frame" node 31a and the "Column" node 31a and "Beam" node 31a one level lower.

[0111] Furthermore, when a building is constructed in a domestic suburb using wooden panel construction, it is assumed that the site will be fairly large, and therefore line 31c is arranged on the assumption that all the components will be assembled in panels on-site. Specifically, as shown by the dashed dotted line in Fig. 15, when a building is constructed in a domestic suburb using wooden panel construction, line 31c is arranged to cross "foundation" node 31a and "framework" node 31a, as well as "column" node 31a and "beam" node 31a, etc., which are one level lower. Furthermore, line 31c is arranged to cross "building" node 31a, which is the highest level, and "panel" node 31a, etc., which are one level lower.

[0112] In addition, when a building is constructed in a domestic city center using a wooden panel construction method, if all the components are made into panels, it is expected that the cost and lead time will not be optimal due to the need for cranes and transportation. For this reason, the line 31c is arranged on the assumption that some components (e.g., floors, etc.) will be constructed on-site. Specifically, as shown by the two-dot chain line in FIG. 15, when a building is constructed in a domestic city center using a wooden panel construction method, the line 31c is arranged to cross the "foundation" node 31a and the "frame" node 31a, as well as the "column" node 31a and the "beam" node 31a, etc., which are one level lower. In addition, the line 31c is arranged to cross the "panel" node 31a and the "floor" node 31a, the "ceiling" node 31a, the "roof" node 31a, etc., which are one level lower.

[0113] In this way, by setting line 31c according to three regions (overseas, suburban areas in Japan, and urban areas in Japan) with different traffic conditions and legal regulations, the work locations for each type of work when constructing a building using wooden panel construction methods can be appropriately set at the design finalization stage.

[0114] 16 is a diagram showing an example of a template 31 for constructing a building using a metalwork construction method in which joints and connections are joined with metalwork. When constructing a building using the metalwork construction method, three templates are prepared with different lines 31c set for overseas, suburban areas in Japan, and urban areas in Japan.

[0115] More specifically, when a building is constructed overseas using metalwork construction, the line 31c is arranged on the assumption that as much of the building will be prefabricated (manufactured in a factory). Specifically, as shown by the solid line in Fig. 16, when a building is constructed overseas using metalwork construction, the line 31c is arranged to cross the top "building" node 31a and the "foundation" node 31a one level lower. Also, the line 31c is arranged to cross the "structure" node 31a and the "wall" node 31a, etc., and the "column" node 31a and the "beam" node 31a, etc., one level lower.

[0116] Furthermore, when a building is constructed in the suburbs of a country using metalwork construction, line 31c is arranged on the assumption that metalwork, etc. will be preset in a factory and assembled on site, taking into consideration that the cost and lead time required for transportation is relatively short (compared to urban areas). Specifically, as shown by the dashed dotted line in Fig. 16, when a building is constructed in the suburbs of a country using metalwork construction, line 31c is arranged to cross "body" node 31a and the next lower "column" node 31a, "beam" node 31a, "flint" node 31a, etc.

[0117] Furthermore, when metalworking is used to construct buildings in urban areas in Japan, the cost and lead time required for transportation are relatively large, so line 31c is arranged on the assumption that metalworking is not pre-set in the factory. In this way, line 31c is arranged so that components manufactured in the factory can be transported all at once, thereby shortening the cost and lead time. Specifically, as shown by the two-dot chain line in FIG. 16, when metalworking is used to construct buildings in urban areas in Japan, line 31c is arranged to cross "column" node 31a and the "pre-cut lumber" node 31a one level lower. Line 31c is also arranged to cross "beam" node 31a and the "pre-cut lumber" node 31a one level lower.

[0118] By using the template 31 shown in FIG. 16, the work locations for the types of work to be performed when constructing a building using the metalwork method can be appropriately set at the design confirmation stage.

[0119] As described above, the calculation system 1 according to this embodiment comprises a design unit 10 which designs a building, and a structure calculation unit 30 (hierarchy information calculation unit) which calculates a residence-specific structure A31 (hierarchy information) which indicates in stages the parent-child relationships of various components used in the building based on the design information (summary information) designed by the design unit 10.

[0120] By configuring in this way, the total costs A51 to A53 of the building can be calculated with high accuracy using the residence-specific structure A31.

[0121] In addition, the calculation system 1 further includes a part calculation unit 20 (output unit) capable of outputting detailed information (part model A21) indicating the details of the building designed by the design unit 10 to the structure calculation unit 30, and the design unit 10 inputs the design information to the part calculation unit 20 (processing "2" shown in Figure 8), the part calculation unit 20 outputs the detailed information according to the input result of the design information to the structure calculation unit 30 (processing "3" shown in Figure 8), and the structure calculation unit 30 calculates the individual residence structure A31 based on the output result of the design information and the detailed information (processing "5" shown in Figure 8).

[0122] With this configuration, the detailed information held in the part calculation unit 20 can be used to accurately calculate the individual house structure A31, and therefore the total costs A51 to A53 of the building can be accurately calculated.

[0123] In addition, the individual house structure A31 stores the identification information of the various components, the parent-child relationships, and the identification information of the work location corresponding to the construction type of the building in association with each other.

[0124] With this configuration, cost fluctuations due to differences in work locations can be reflected in the total costs A51 to A53, so that the total costs A51 to A53 of the building can be calculated with high accuracy.

[0125] Moreover, the work site is set based on the construction method of the building and the area where the building is to be constructed (FIGS. 13 to 16).

[0126] By configuring in this manner, the work location can be appropriately specified taking into account differences in construction methods and regions.

[0127] The area includes a plurality of areas with different traffic conditions or building regulations.

[0128] With this configuration, it is possible to calculate the total costs A51 to A53 of the building taking into account factors that are likely to cause cost fluctuations (traffic conditions and laws and regulations), so that the total costs A51 to A53 can be found with high accuracy.

[0129] In addition, the design information includes the construction method and the region, and the structure calculation unit 30 further includes a plurality of templates 31 whose parent-child relationships and work locations differ according to the construction method and the region, and extracts one template 31 from the plurality of templates 31 according to the construction method and the region of the design information, and calculates the per-house structure A31 by reflecting the contents of the summary information and the detailed information in the extracted one template 31 (processing of "4" and "5" shown in Figure 8).

[0130] By configuring in this manner, the residence-specific structure A31 can be easily calculated using the template 31.

[0131] In addition, the calculation system 1 further includes a comprehensive information calculation unit 40 that calculates at least one of the total costs A51 to A53 or the total lead times B51 to B53 required for constructing the building based on the calculation results of the individual residence structure A31 (in this embodiment, the total costs A51 to A53 or the total lead times B51 to B53, respectively).

[0132] By configuring in this way, the total costs A51 to A53 and the total lead times B51 to B53 of the buildings can be calculated with high accuracy.

[0133] In addition, the comprehensive information calculation unit 40 is equipped with a work type component library 44 (work type calculation unit) capable of calculating the cost A44 and lead time B44 according to the work type required for constructing the building, and an arrangement unit 47 (schedule creation unit) capable of creating schedules 51-53 by arranging the work types in chronological order based on the calculation result of the lead time B44 according to the work type, and calculates the total cost A51-A53 based on the calculation result of the cost A44 according to the work type, and calculates the total lead time B51-B53 based on the creation results of the schedules 51-53.

[0134] By configuring in this way, the total costs A51 to A53 and the total lead times B51 to B53 can be calculated with high accuracy.

[0135] As described above, the calculation system 1 according to this embodiment includes a structure calculation unit 30 (hierarchy information calculation unit) that calculates a per-house structure A31 (hierarchy information) that indicates in a hierarchical manner the parent-child relationships of various components used in the building to be designed, and a comprehensive information calculation unit 40 that calculates at least one of the total costs A51-A53 or the total lead times B51-B53 required for the construction of the building based on the calculation results of the per-house structure A31 (in this embodiment, the total costs A51-A53 and the total lead times B51-B53, respectively).

[0136] With this configuration, the parent-child relationships of the various building components can be grasped from the individual structure A31, so that the total costs A51 to A53 and the total lead times B51 to B53 of the building can be calculated with high accuracy.

[0137] In addition, the comprehensive information calculation unit 40 is equipped with a work type component library 44 (work type calculation unit) capable of calculating the cost A44 and lead time B44 according to the work type required for constructing the building, and an arrangement unit 47 (schedule creation unit) capable of creating schedules 51-53 by arranging the work types in chronological order based on the calculation result of the lead time B44 according to the work type, and calculates the total cost A51-A53 based on the calculation result of the cost A44 according to the work type, and calculates the total lead time B51-B53 based on the creation results of the schedules 51-53.

[0138] By configuring in this way, the total costs A51 to A53 and the total lead times B51 to B53 can be calculated with high accuracy.

[0139] In addition, the work type component library 44 calculates the cost and lead time required for work associated with the work type, and calculates the cost A44 and lead time B44 corresponding to the work type by taking into account the calculation results of the cost and lead time.

[0140] By configuring in this manner, the cost A44 and lead time B44 according to the type of work can be calculated with high accuracy.

[0141] Moreover, the work type component library 44 includes a plurality of work type components 44a (calculation processing units) that calculate the cost and lead time according to the work type for each work location according to the work type.

[0142] By configuring in this way, the fluctuations in cost A44 and lead time B44 due to differences in work locations can be reflected in the total costs A51 to A53 and total lead times B51 to B53, so that the total costs A51 to A53 and total lead times B51 to B53 can be calculated with high accuracy.

[0143] In addition, the overall information calculation unit 40 further includes a manufacturing calculation information DB41 and a construction calculation information DB42 (multiple first memory units) that store, for each work location, predetermined values ​​required for calculating the cost A44 and lead time B44 according to the work type, and the multiple work type components 44a calculate the cost A44 and lead time B44 according to the work type using information from the manufacturing calculation information DB41 and the construction calculation information DB42, and the overall information calculation unit 40 further includes a manufacturing and construction work type DB45 (second memory unit) that stores the manufacturing calculation information DB41, construction calculation information DB42 and the multiple work type components 44a in association with each other according to the work type and the work location.

[0144] By configuring in this way, it is possible to easily obtain the cost A44 and the lead time B44 according to the type of work by using the information stored in the manufacturing and construction type DB45.

[0145] The arrangement unit 47 creates the process charts 51 to 5N based on the calculation result of the lead time B44 according to the type of work and constraint information 46 (information on preset constraints).

[0146] By configuring in this way, the process charts 51 to 5N can be appropriately created in accordance with the constraint information .

[0147] The arrangement unit 47 creates a plurality of process schedules 51 to 5N in which the arrangement of the work types is different.

[0148] By configuring in this way, it is possible to improve convenience. In particular, the arrangement unit 47 presents to the customer a part of the process schedules 51 to 53 that are obtained by narrowing down the created process schedules 51 to 5N (processing of "8" shown in FIG. 11). In this way, the arrangement unit 47 can reduce the burden on the customer of selecting a process schedule.

[0149] In addition, the calculation system 1 further includes a design unit 10 that designs the building, and a structure calculation unit 30 (hierarchical information calculation unit) that calculates the residence-specific structure A31 based on the design information (summary information) designed by the design unit 10.

[0150] With this configuration, the individual residence structure A31 can be calculated with high accuracy using the design information, and the total costs A51 to A53 and the total lead times B51 to B53 can be calculated with high accuracy.

[0151] In addition, the calculation system 1 further includes a part calculation unit 20 (output unit) capable of outputting detailed information (part model A21) indicating the details of the building designed by the design unit 10 to the structure calculation unit 30, and the design unit 10 inputs the design information to the part calculation unit 20 (processing "2" shown in Figure 8), the part calculation unit 20 outputs the detailed information according to the input result of the design information to the structure calculation unit 30 (processing "3" shown in Figure 8), and the structure calculation unit 30 calculates the individual residence structure A31 based on the output result of the design information and the detailed information (processing "5" shown in Figure 8).

[0152] With this configuration, the individual residence structure A31 can be accurately calculated based on the design information (summary information) and the detailed information, and the total costs A51 to A53 and the total lead times B51 to B53 can be accurately calculated.

[0153] The structure calculation section 30 according to this embodiment is an embodiment of a hierarchy information calculation section. Moreover, the part calculation unit 20 according to this embodiment is an embodiment of an output unit. Moreover, the work type component library 44 according to this embodiment is one embodiment of a work type calculation unit. The arrangement unit 47 according to the present embodiment is an embodiment of a schedule creation unit. Moreover, the work type component 44a according to the present embodiment is one embodiment of a calculation processing unit. Moreover, the manufacturing calculation information DB 41 and the construction calculation information DB 42 according to the present embodiment are an embodiment of a plurality of first storage units. The manufacturing construction type DB 45 according to the present embodiment is an embodiment of a second storage unit.

[0154] Although the embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0155] For example, the calculation system 1 is configured with a plurality of PCs, but the hardware configuration of the calculation system 1 is not particularly limited, and devices other than PCs (e.g., tablet terminals, etc.) may be used. The number of devices constituting the calculation system 1 may be an appropriate number depending on the scale of the system, etc.

[0156] In addition, the individual structure A31 does not necessarily have to specify the work location. In addition, the general information calculation unit 40 can calculate the cost A44 and the lead time B44 according to the work type without considering the work location.

[0157] Furthermore, the work location (line 31c) is set based on the construction method, region, and the like, but the criteria for setting the work location are not particularly limited, and other criteria may be used.

[0158] Furthermore, the regions used as the criteria for setting work locations were overseas, suburban areas within Japan, and urban areas within Japan, but there are no particular limitations on how the regions are divided.

[0159] In addition, the structure calculation unit 30 employs a method of calculating the individual residence structure A31 using the template 31, but the calculation method of the individual residence structure A31 is not particularly limited. For example, the structure calculation unit 30 can calculate the individual residence structure A31 using a method that does not use the template 31.

[0160] Furthermore, although the overall information calculation unit 40 has calculated the total costs A51 to A53 and the total lead times B51 to B53, the overall information calculation unit 40 can also calculate at least either the total costs A51 to A53 or the total lead times B51 to B53.

[0161] In addition, the work type component library 44 calculates the cost A44 and lead time B44 according to the work type by taking into account the cost and lead time of the work associated with the work type, but there is no particular limitation on how the cost A44 and lead time B44 are calculated.

[0162] In addition, the manufacturing and construction work type DB 45 stores the work type component 44a and the manufacturing and construction component 43a in advance in association with each other, but this is not limited thereto, and for example, the work type component 44a and the manufacturing and construction component 43a may be stored in association with each other after the design is finalized. In this case, the structure calculation unit 30 may specify the work type component 44a and the manufacturing and construction component 43a to be associated based on, for example, the construction method and the region (line 31c), and may appropriately associate the specified work type component 44a.

[0163] Further, the arrangement unit 47 has created a plurality of process schedules 51 to 5N, but is not limited thereto, and may create one process schedule. In this case, the arrangement unit 47 may create one process schedule according to, for example, a customer's request. [Explanation of symbols]
