Description

The present invention relates to a design support device that supports development and design in a house maker.

The house maker predetermines the type, form, and layout rules of standard floor plans and components (for example, roofs, balconies, stairs, sashes, equipment, etc.). Then, based on the predetermined floor plan rules and components, the detailed building contents are discussed with the customer, and a building plan for the residential building ordered from the customer is created.

In addition, in order to support mass production, a housing maker creates drawings of various components in a standard building plan in the development design (development design department) before receiving an order for housing construction. In the development design, various drawings such as components, parts forming the components, and parts for attaching the components to the skeleton are created. In addition, the housing maker creates manufacturing drawings for the ordered building plan based on various drawings created in the development design, and manufactures components such as the frame and stairs of the ordered house.

On the other hand, there are various variations of housing components (for example, in the case of stairs, stair types such as folded stairs and round stairs), and the relationship with other components such as the position to be placed and adjacent parts depending on the variation. May be different.

Here, in Patent Document 1, for each of the products, a symbol representing the product, a symbol representing a component constituting the product, and a difference in usage conditions such as the number of used parts and the length of the component with other products. A method for automatically creating component component information is disclosed in which the presence or absence of is registered.

Japanese Unexamined Patent Publication No. 7-23490

By the way, in the development design of a housing maker, with the development of a new product, new components are added (and variations of the components are added) and specifications of the components are changed (changes to other variations). Then, drawings are created according to the changes in the components.

A house maker makes it easy to create a building plan according to a customer's request by planning a plurality of standard building rules (layout rules) and parts (components) in advance. However, the needs of customers requesting housing construction are diversifying, and for example, variations of stairs are on the rise. For this reason, in development design, which is responsible for product development in housing manufacturers, it is required to formulate new building rules (layout rules, etc.) and components that can respond to customer needs and changes in needs.

Here, in the development design of a housing maker, it is conceivable to create a large number of floor plan rules, components, and variations thereof so as to respond to customer needs and changes in needs. As a result, in development design, it is possible to secure time for planning new building rules (such as floor plan rules) and variations of components.

However, creating a large number of floor plan rules, components, and variations thereof means creating drawings for each variation in the development design, which requires enormous man-hours. In addition, in a house, a plurality of components are attached in relation to each other, and in the development design, not only the variation of one component is changed, but also other components related to the changed component. Work corresponding to changes in parts, etc. is required, and the work man-hours tend to increase. Further, if a variation that does not receive an order occurs among a plurality of variations in which the drawing is created by spending the work man-hours in the development design, the work man-hours spent on creating the drawing of the variation are wasted. For this reason, in development design, it is desired to improve work efficiency so that building rules (layout rules) and components that match customer needs and changes in needs can be drafted with limited work man-hours.

The present invention has been made in view of the above facts, and an object of the present invention is to provide a design support device that supports efficient development and design of a building.

In order to achieve the above object, the design support device according to the first aspect of the present invention provides, for each variation of each component constituting the building, part information regarding the parts forming the variation, and the component information of the building of the variation. An information storage unit that stores assembly information related to assembly to a structure and other surrounding components, and the variation of the component in the building configured by setting one of the variations for each component. The information output unit includes an information output unit that generates and outputs influence degree information regarding the influence degree on the structure and the other components based on the component information and the assembly information of the variation.

A building is constructed by assembling a plurality of components to a structure forming a skeleton, and each of the components has a plurality of variations. In the building plan, one variation is set for each of the components from a plurality of variations.

Generates and outputs impact information about.

The drawing information and the assembly information of the variation before the change and the variation after the change are stored in the information storage unit, the drawing information includes the information about the parts forming the variation, and the assembly information is the structure of the variation. And includes information on assembly to other components. For this reason, the impact information includes not only the presence or absence of changes in the parts that make up the variation when the variation of the component is changed, newly required parts, and unnecessary parts, but also the structure and other configurations. The degree of influence on the product is included. In addition, the degree of influence on the structure and other components includes whether or not the structure has been changed and whether or not other components have been changed, and when there is a change in the structure or when the other component is changed. Includes the changes, if any.

As a result, in the development design, it becomes easy to create drawings when changing the variation of the component from the influence degree information, and the influence on the structure and other components by changing the variation of the component can be grasped. it can. Therefore, when the variation of the component is changed, it is possible to appropriately create drawings, etc. not only for the component with the changed variation but also for other components affected by the change of the variation. Can properly support work in design.

The design support device of the second aspect is the design support device of the first aspect, based on the construction results for each variation of the component of the built building, for each variation of the new building component. Includes a performance output unit that predicts and outputs the appearance rate of.

In the design support device of the second aspect, the construction results for each variation are accumulated for the components of the constructed building. The performance output unit predicts and outputs the appearance rate of each variation of the components in a new building based on the accumulated construction results.

Here, if there are only variations with a low appearance rate, it is conceivable to develop and design drawings and the like after the order starts. For this reason, from the predicted appearance rate of components, variations with a high appearance rate are developed and designed in advance (before the start of orders), but variations with a low (low) appearance rate are started to receive orders. It is possible not to develop and design before (refrain from development and design). As a result, it is possible to suppress an increase in work in the development design before receiving an order, and it is possible to improve the efficiency of the work in the development design.

The design support device of the third aspect is the design support device of the first or second aspect, which includes an interest level acquisition unit that acquires and accumulates customer interest level information for each variation of the component, and the interest level. It further includes a degree of interest prediction unit that predicts and outputs the appearance rate of each variation of the components of a new building based on the degree information.

Based on the accumulated interest level information, the interest level prediction unit predicts and outputs the appearance rate of each variation of the components when a new building is constructed.

Therefore, from the predicted appearance rate, variations with high customer interest in the components can be predicted, and variations with high customer interest and high appearance rate are developed and designed before the start of orders. However, variations that are expected to have a low degree of interest and a low appearance rate can be left undeveloped and designed before the start of orders. As a result, it is possible to suppress an increase in work in the development design before receiving an order, and it is possible to improve the efficiency of the work in the development design.

As described above, according to the first aspect of the present invention, it is possible to obtain an effect that appropriate support for improving work efficiency in development design becomes possible.

Further, according to the second and third aspects of the present invention, it is possible to efficiently select drawings and the like to be created before the start of ordering in the development design, so that even if there are a plurality of variations in the components, the work in the development design The effect of suppressing the increase in man-hours can be obtained.

Further, the unit information includes a parts list, a drawing number, a parts drawing of each part, an assembly drawing, a parts drawing, a work man-hour required to create the assembly drawing, and the like, which constitute the building unit 50.

As a result, in the building design, from the building design information output from the design support device 10, the drawings necessary for manufacturing the staircase unit 52, the mounting parts, and the building unit 50 to which the staircase unit 52 is mounted in the made-to-order building plan ( (Manufacturing drawings), etc. can be grasped, and the work manpower required for creating drawings, etc., and the flow of the manufacturing process based on the created drawings, etc. can be grasped. Therefore, in the architectural design, for the made-to-order building plan, drawing creation (design) for manufacturing the staircase unit 52, the building unit 50 in which the staircase unit 52 is installed, and the mounting parts used for mounting the staircase unit 52 is efficiently performed. It can be done and the work efficiency of manufacturing can be improved.

By the way, a housing maker may add or change variations of components (for example, staircase units) with respect to a standard plan by performing development and design in response to customer needs. In addition, variations of the standard plan may be added (addition of the standard plan) or changes may be made.

In the development design, if there are additions or changes such as variations of the standard plan and components, the design information of the corresponding standard plan is corrected (changed). FIG. 6 is a flow chart showing an outline of the design support process executed by the design support device 10 when the variation of the component is changed.

The flowchart of FIG. 6 is executed when change information for adding / changing a variation of a component is input to the data receiving unit 20, and in the first step 100, is the variation of the component to be changed a new variation? Check if, that is, if the changed stair type is a new stair type.

When changing the component, the change information input to the data reception unit 20 includes a code for specifying the component to be changed, the content of the change, and the like. Further, for a new variation in which a code is not set, a new code is set and the design information of the component is input together with the set code. For example, when the component is a staircase, a staircase code, a mounting part code, a unit code, etc. for specifying the staircase type are input to the data receiving unit 20, and staircase information, mounting part information, usage information, unit information, etc. Is created and entered.

Here, if the change is between existing variations such as changing the stairs to another stair type, a positive determination is made in step 100, and the process proceeds to step 102. In step 102, the input change information (stairs code, etc.) is acquired, and the information related to the stairs type is updated in the corresponding standard plan or custom-built building plan.

In the next step 104, the design information for each of the components (stairs) and its variations is changed based on the information (stairs code, changes, etc.) about each of the components and their variations read out in step 102. The influence degree information generated by the above is generated, and in step 106, the generated influence degree information is output (output unit 32).

The stairs information includes drawing information such as parts list, drawing number (number of drawings), parts drawing of each part, mounting information such as assembly drawing, work information such as work man-hours required to create each drawing, and stairs. Contains relevant information for components such as partitions around the. The mounting parts information includes drawing information such as a parts list, drawing number (number of drawings), parts drawing of each part, work information such as work man-hours required to create each drawing, and a staircase unit 52 as a building unit 50. Includes mounting information such as assembly drawings (construction drawings) for mounting. The usage information includes usage information of the space around the staircase unit 52, and the usage information includes information on components such as partitions. In addition, the unit information includes the parts list, the drawing number (number of drawings), the design information such as the parts drawing of each part, the mounting information such as the assembly drawing for mounting the staircase unit 52, and these. Includes work information such as the work man-hours required to create the drawings.

Therefore, in order to use the difference in the parts of the stairs unit 52 when the stairs type is changed, the difference in the mounting parts, and the surrounding space from the stairs information, the mounting parts information, the usage information, and the unit information in the influence degree information. Information that can grasp the difference between the parts and the like of the above and the difference between the parts of the building unit 50 is included. In addition, the influence degree information includes information that can grasp the work man-hours required for creating a drawing for changing the staircase type.

As a result, in addition to the drawing of the stairs itself required to change the stairs type from the influence degree information, the work man-hours for drawing, etc., the components that need to be changed due to the influence of the stairs being changed. It is possible to grasp the necessity of drawing required for changing (for example, partition around stairs), man-hours for drawing, man-hours for manufacturing the building unit 50, man-hours for updating equipment for manufacturing, costs, etc. .. That is, if only the stairs information, mounting parts information, usage information, and unit information after the change are output, it is possible to grasp what kind of parts will be used, but it is necessary before the change, but after the change. It becomes difficult to properly grasp unnecessary parts and the like. Further, although it looks like the same building unit 50, when the mounting position and mounting method of the staircase unit 52 are different, it may be difficult to grasp the difference. Furthermore, there is a possibility that the partition or the like may be affected depending on whether the space around the stairs is used for a storage, a toilet, a corridor, or neither.

Here, in the development design, by outputting the influence degree information from the design support device 10, it is possible to grasp all the changes necessary for other components due to the change of the staircase type and proceed with the work. , It is possible to suppress the occurrence of work omission in the drawing work, and the work efficiency can be effectively improved. Further, when the space around the stairs is used as a storage, a toilet or a corridor, it is possible to appropriately determine whether or not the partition or the like can be changed by changing the stairs type. In addition, since the work man-hours required for drawing creation and the like can be grasped, accurate work in development design can be performed, and work efficiency in development design can be improved.

Further, since the influence degree information is generated by comparing the unit information, it is possible to grasp whether or not the building unit 50 to which the staircase unit 52 is attached needs to be changed, and if the change is necessary, the content of the change is appropriate. Can be grasped. Therefore, it is possible to suppress leakage in the manufacturing of the building unit 50 and the work of assembling the staircase unit 52 to the building unit 50, and it is possible to suppress a decrease in work efficiency of the development design and manufacturing work. It is possible to suppress a decrease in work efficiency in work.

Further, the influence degree information can grasp the influence on the manufacturing work for assembling the staircase unit 52, the mounting parts, the building unit 50, and the building unit 50 to the staircase unit 52. A component with a large number of other components affected by changing the variation (a component with a large degree of influence) is a component with a low degree of influence (a component with a small number of other components affected). Compared to, by changing the variation, the work man-hours in development and design increase, and the cost is high (bulk). From here, in the development design before the start of orders, for components with a large impact, change of variation is postponed (existing variation), and for components with low impact, variation is increased (variation is changed). You can also do it. As a result, it is possible to improve the efficiency of the design work in the development design for the change of the variation of the component before the start of the order.

On the other hand, if the variation (staircase type) of the component to be changed is new, an affirmative determination is made in step 100, the process proceeds to step 108, and design information of the new variation is acquired. Further, in step 110, the acquired design information is stored in the first storage unit 24 as design information of a new variation of the component. The design information includes, for example, stairs information for each stair type, mounting parts information for mounting parts for each stair type, usage information for the space around the stairs, and building for each stair type, as in the existing components (variations). The unit information of the unit 50 and the like are included. As a result, variations of components will be added to the standard plan.

After that, the process proceeds to step 104 to generate impact information by changing the variation of the component, and output the generated impact information (step 106). As a result, the design support device 10 can prevent oversight and unnecessary work in the development design even when a variation of a new component is added to the component of the standard plan. Therefore, the design support device 10 can suppress omissions and omissions in the drawing creation work in the development design.

By the way, in the first storage unit 24, the design information of each of the plurality of standard plans is stored, and the building information of the custom-made construction plan is accumulated as the construction record information, and the building record information includes each variation of the component. Construction results and changes in construction results are included. In the learning unit 26, the foundation is based on the total number of building information (custom-made building plans) accumulated in the first storage unit 24 and the construction results for each predetermined period (for example, 1 month, 3 months, 6 months, 1 year, etc.). Calculate the construction results (building results) for each variation of the standard plan and each component. In addition, the learning unit 26 calculates the appearance rate (utilization rate) of the standard plan in the made-to-order construction plan and the appearance rate (construction performance rate) for each variation of the components based on the calculation result.

In addition, the learning unit 26 predicts variations of the standard plan and components included in the newly ordered construction plan from the changes in the construction results for each variation of the components. The learning unit 26 calculates the appearance rate for each variation of the standard plan and the component, and stores the calculated appearance rate in the second storage unit 28.

For example, it is predicted that the appearance rate is low for standard plans and staircase types, which have a large number of past construction results but whose construction results are decreasing (the construction results are changing to decrease). In addition, although the past construction results are small, the appearance rate is expected to be high for standard plans and staircase types whose construction results are increasing.

In addition, the learning unit 26 uses the building information of each of the plurality of standard plans stored in the first storage unit 24 and the data representing the building performance information as learning data, and the layout rules or components from the building information of the standard plan. A trained model that derives the variation of the building plan and a trained model that derives the building plan from the layout rule or the variation of the component are generated. For example, the learning unit 26 generates a learned model that derives a staircase type from building information excluding stairs. At this time, the learning unit 26 generates a learning model by performing deep learning based on the appearance rate and the change in the appearance rate for each staircase type. The trained model generated in the learning unit 26 is stored in the second storage unit 28.

Here, when the design support device 10 receives an output instruction of the appearance rate for the variation of the standard plan or the component, the output information generation unit 30 reads the instructed appearance rate from the second storage unit 28 and outputs the output unit. 32 outputs. As a result, in the development design, from the output of the design support device 10, it is possible to predict the variation of the components in the standard plan that is the basis of the build-to-order building plan and the build-to-order building plan for the next term.

Further, in the design support device 10, for example, when a building plan (building information) such as a standard plan excluding the stairs type is input and an output of building information including the stairs type is instructed, the output information generation unit 30 Reads from the second storage unit 28, but uses the trained model to derive the staircase type from the input building information. The output unit 32 outputs the input building information including the staircase type derived from the trained model. As a result, for example, an architectural plan that includes a staircase type with a high appearance rate in the standard plan can be obtained.

In the design support device 10, the appearance rate of each variation of the component can be grasped by accumulating the construction results of each variation of the component. Further, the design support device 10 can output the work man-hours in the development design as well as the degree of influence on other components when the variation of the components is changed.

For this reason, when deciding which component to change in the development design, design information is created before the start of orders (product launch) for variations with a high or expected appearance rate predicted from the construction results. Can also be done. For example, in the design and development before the start of orders, for components with a small number of other components that are affected by changing variations (components with a small degree of influence), but with a low appearance rate, It is possible to increase the variation for the component with a high appearance rate, although it is a component with a large number of other components affected (component with a large degree of influence) without increasing the variation.

As a result, it is possible to prevent the development and design work performed before the start of the order from being wasted, and to improve the work efficiency. Moreover, since the design support device 10 can grasp the appearance rate for each predetermined period, for example, for variations in which the appearance rate tends to increase, the customer's needs can be obtained by creating design information or the like before the start of receiving an order. A standard plan that meets the requirements can be prepared, and the probability of receiving an order for a construction plan can be increased.

The construction results for each variation of the component will change according to the needs of the customer. From this, when predicting the appearance rate for each variation of the component, weighting is performed so that the appearance rate is low for variations whose appearance rate is decreasing, and the appearance rate is high for new variations. The weighting may be performed as follows. As a result, it is possible to suppress waste in creating design information and the like in the development design before the start of receiving an order, and it is possible to efficiently create design information and the like that meet the needs of the customer. In addition, for new variations, sales promotion of the variations can be promoted.

The appearance rate of each variation of the components acquired in this way may be reflected in the standard plan presented to the customer by the housing maker. This makes it possible to present the customer with a standard plan that is close to the customer's needs. In addition, by using the trained model, it becomes easy to set a new standard plan from the layout rules or variations of components, and it is possible to improve the efficiency of setting (development) of the standard plan in the development design.

[Second Embodiment]
Next, the second embodiment will be described.
In the second embodiment, the design support device 36 and the mobile terminal 38 as the information acquisition unit are used instead of the design support device 10. FIG. 7 shows the design support device 36 and the mobile terminal 38 according to the second embodiment in a schematic configuration diagram, and FIG. 8 shows the design support device 36 and the mobile terminal 38 in a functional block diagram. There is.

As shown in FIG. 8, the design support device 36 is formed with a communication unit 34. The communication unit 34 can be realized by the network interface 12E, and can be connected to a plurality of mobile terminals 38 via a network (for example, a public communication network such as the Internet) by a wireless system or a wired system.

In the design support device 36, the information acquired by inputting from the mobile terminal 38 to the data receiving unit 20 is stored in the first storage unit 24. Further, in the design support device 36, the output information generation unit 30 reads the information (data) stored in the second storage unit 28 and generates the output information.

As shown in FIG. 7, as the mobile terminal 38, for example, a tablet terminal or the like is used. The mobile terminal 38 includes a CPU 40A, a ROM 40B, a RAM 40C, a storage 40D, an input / output device 40E, and a communication interface (which may be a wireless network interface) 40F. In the mobile terminal 38, a predetermined processing function is realized by the CPU 40A executing the program stored in the ROM 40B.

The input / output device 40E uses a touch-type display in which an input device and an output device (display device) are integrated, and in the mobile terminal 38, various information can be viewed by touching the input / output device 40E. Is possible.

As shown in FIG. 8, the mobile terminal 38 is formed with a browsing data storage unit 42A, a browsing unit 42B, a log storage unit 42C, and a communication unit 42D. The browsing data storage unit 42A and the log storage unit 42C are realized by using the storage 40D, the browsing unit 42B is realized by using the input / output device 40E, and the communication unit 42D is realized by using the communication interface 40F. Has been done.

In the browsing data storage unit 42A, the data of each of the plurality of standard plans devised by the housing manufacturer and the data of a plurality of variations for each component such as a plurality of staircase types (variations of stairs) are electronic catalog data (booklet data). It is stored as. The reading unit 42B enables browsing of the electronic catalog on the input / output device 40E. The log storage unit 42C stores the browsing history of the electronic catalog in the browsing unit 42B. The communication unit 42D sends (transmits) the browsing history stored in the log storage unit 42C to the design support device 36.

Next, the operation in the second embodiment will be described.
The housing maker lends the mobile terminal 38 to a customer who is considering housing construction, a customer who plans to order a housing construction, or a customer whose construction plan to order is roughly defined (including a customer who has ordered a housing construction). As a result, the customer can browse the electronic catalog stored in the mobile terminal 38. A terminal code that identifies the terminal (may be a customer code that can identify the customer) is set in the mobile terminal 38, and the terminal code is associated with, for example, an order code of an order construction plan when an order for housing construction is received from a customer. ..

The customer who receives the mobile terminal 38 can browse the electronic catalog of the staircase type and consider the staircase type in the construction plan to be ordered. In the mobile terminal 38, when the customer browses the electronic catalog, the browsing page (the type of stairs being browsed), the number of browsing times, the browsing time of each time, and the like are stored in the log storage unit 42C together with the browsing date and time.

The design support device 36 connects to the mobile terminal 38 at a preset timing such as the timing when the mobile terminal 38 is returned from the customer, and acquires the browsing history of the electronic catalog from the mobile terminal 38. FIG. 9 shows an example of the design support process using the browsing history executed by the design support device 36 in a flow chart.

The flowchart of FIG. 9 is repeatedly executed at preset time intervals, and in the first step 120, it is confirmed whether or not it is the timing to acquire the browsing history from the mobile terminal 38. At this time, if the timing is set to acquire the browsing history, a positive determination is made in step 120 and the process proceeds to step 122. The timing of acquiring the browsing history from the mobile terminal 38 is not limited to the timing when the mobile terminal 38 is returned from the customer, but at any time such as every day or every other day during the period when the mobile terminal 38 is lent to the customer. Applicable.

In step 122, the browsing history of the electronic catalog is acquired from the mobile terminal 38, and in step 124, the browsing information of the customer obtained from the acquired browsing history is stored and stored in the first storage unit 24. As a result, for example, the staircase type browsed from the browsing page of the electronic catalog is specified in the first storage unit 24, and the number of browsing times, the browsing time, the browsing time, the browsing date and time, etc. for each staircase type are accumulated. Further, in the first storage unit 24, information indicating the staircase type that the customer is interested in is accumulated for the staircase type of the house maker, and the number of times of browsing, the browsing time, the browsing time, and changes thereof for each staircase type are accumulated. Is accumulated.

After that, in step 126, from the browsing history accumulated in the first storage unit 24, the interest level information of the staircase type (variation of the component) for each customer and the staircase type (for each variation of the component) of the stairs are obtained. Generate interest level information. Further, in step 126, as interest level information, information indicating changes in the interest levels of each customer and all customers for the staircase type is generated, and the generated interest level information is stored in the second storage unit 28. By updating the browsing history stored in the first storage unit 24, the interest level information stored in the second storage unit 28 is updated.

In the next step 128, it is confirmed whether or not the output request of the customer's interest level information has been made for the component. For example, a predetermined user interface is displayed on the display device 16, and a customer code corresponding to the customer or a terminal code lent to the customer is specified by operating the input device 14 (mouse or keyboard) to output customer interest level information. When the request is input to the data receiving unit 20, an affirmative determination is made in step 128 and the process proceeds to step 130. Even if a negative determination is made in step 120, the process proceeds to step 128.

In step 130, the staircase type interest level information is read from the second storage unit 28 for the specified customer, and the appearance rate for each staircase type is calculated from the information indicating the customer's degree of interest for each staircase type included in the interest level information. Predict and output. Customer interest information includes total browsing time for stairs, browsing time for each stair type, total number of browsing for stairs, number of browsing for each stair type, browsing date and time, and the like.

From this, it is possible to predict whether or not the customer is interested in changing the stair type from the ratio of the stair type browsing time to the total browsing time for the stairs, and when the ratio of the stair type browsing time to the total browsing time is high. Can be predicted that customers are interested in changing the staircase type. In particular, in the initial stage of using the mobile terminal 38, the number of views of the stairs and the stairs type is small, but if the number of views gradually increases, it can be predicted that the customer is highly interested in changing the stairs type.

Also, if the customer is expected to be interested in changing the stair type, the ratio of views for each stair type to the total number of views for the stairs indicates whether or not they are interested in a particular stair type. If it can be predicted and it is predicted that the person is interested in a specific staircase type, the appearance rate of the staircase type can be predicted to be high. In predicting the degree of interest (appearance rate), the ratio of browsing time may be matched with the ratio of browsing times, and if the number of browsing times is at least long, the customer shows interest in the applicable staircase type. It can be predicted that the appearance rate will be high.

By predicting the appearance rate of the staircase type from the customer's interest level information in this way, if the customer has not ordered the residential building, the staircase type is set (changed) for the custom-built building plan of the residential building ordered by the customer. The presence or absence and the staircase type that will be changed if there is a change) can be predicted before the order starts. As a result, in development design, it is possible to perform architectural design (manufacturing drawing creation, etc.) for the staircase type in advance, and it is possible to predict variations of components in residential construction where orders are expected from customers, and improve the efficiency of architectural design. Becomes possible.

In addition, if the customer has already ordered a house construction, it is possible to predict whether or not there is a change in variation (change in staircase type) of components such as stairs from the customer's interest level information. That is, if the customer is highly interested in a type (different variation) different from the component in the ordered construction plan from the customer, the customer may wish to change the type (change of variation) of the component. It can be predicted to be higher. From here, in architectural design, it is possible to create architectural drawings for related components after confirming whether or not there are changes in variations of the components, so waste such as drawing creation can be eliminated and efficiency can be improved. It will be possible.

In addition, in architectural design, it is possible to perform work that predicts changes in the variation of components by the customer, so that it is possible to build a house according to the customer's wishes. Further, the design support device 36 can obtain the degree of influence on other components when the variation of the components is changed as in the design support device 10. Therefore, in the architectural design, even if the staircase type or the like is changed, it is possible to suppress waste in the work, and it is possible to suppress the deterioration of the workability of the architectural design.

On the other hand, in step 132, it is confirmed whether or not the output request of the degree of interest information for each staircase type has been made, and when the output of the degree of interest information for each staircase type is instructed, an affirmative determination is made in step 132 and step 134 is performed. Transition. If there is no request to output the degree of interest information, a negative determination is made in step 132 and the process ends.

In step 134, the degree of interest information for each staircase type (for each variation of the component) is read from the second storage unit 28, and the appearance rate for each staircase type is calculated from the information indicating the degree of interest for each staircase type based on the degree of interest information. Predict and output. The second storage unit 28 stores information indicating the appearance rate for each staircase type obtained from the construction record information (construction record), and in step 134, the information indicating the appearance rate obtained from the construction record is stored. It may also be read out to predict the appearance rate.

From the browsing history acquired from each customer, it is possible to predict the staircase type that is currently (interested) highly interested (viewing time). In addition, it is possible to predict the staircase type whose appearance rate is increasing in the constructed houses from the change of the construction results. It can be predicted that such a staircase type is a staircase type with high customer needs and a staircase type with increasing needs.

As a result, in development design, when creating a standard plan, it is possible to create a standard plan that can obtain high satisfaction for new customers by including the staircase type that is expected to have a high appearance rate and high customer needs. .. Therefore, in the development design, it is possible to easily and efficiently create a new standard plan or change an existing standard plan.

In this way, the design support device 36 can learn the degree of interest for each staircase type from the browsing information for each staircase type. Further, in the design support device 36, the construction results for each staircase type can be learned in the same manner as in the design support device 10. As a result, the design support device 36 can accurately predict the staircase type that is highly needed by the customer as the staircase type.

From here, in the development design, the standard plan can be upgraded by changing the standard building plan that has already been drafted to the staircase type that is expected to have high needs. In addition, in development design, it is possible to formulate a new standard plan using the staircase type that is predicted to have high needs, and to propose a high-quality standard plan that meets the needs of customers. Furthermore, in the development design, it is possible to consider abolishing the standard construction plan including the staircase type, which is expected to have few custom-made construction plans as a basis and the needs of customers are low. As a result, the design support device 36 can efficiently upgrade the standard plan in design development, and can appropriately organize the standard plan.

In the second embodiment described above, the mobile terminal 38 was used. However, the information acquisition unit may use a catalog viewing server on the network to which the design support device 36 is connected. In this case, the password is notified to each customer, and the customer can access the catalog viewing server from his / her own personal computer or mobile terminal using the password to view the electronic catalog. Further, the catalog browsing server may transmit the browsing history when the electronic catalog is browsed to the design support device 36.

Further, in the first and second embodiments described above, a staircase is mainly applied as a component, and a staircase type is described as an example as a variation. However, the components are not limited to stairs, and various components constituting the building can be applied. Further, in the first and second embodiments, a unit-type house in which a steel frame rigid frame structure is formed by using a building unit 50 as a building has been described as an example. However, the building may use other structures such as a steel frame structure.

Further, in the first and second embodiments, the functional processing executed by the CPU may be executed by various processors other than the CPU. In this case, as a processor, in order to execute a specific process such as PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacturing FPGA (Field-Programmable Gate Array) and ASIC (Application Specific Integrated Circuit). An example is a dedicated electric circuit or the like, which is a processor having a circuit configuration designed exclusively for it. Further, the functional processing in the first and second embodiments may be executed by one of these various processors, or a combination of two or more processors of the same type or different types (for example, a plurality of FPGAs, etc.). And a combination of CPU and FPGA, etc.). Further, the hardware structure of these various processors is, more specifically, an electric circuit in which circuit elements such as semiconductor elements are combined.
