Below, a temporary housing complex design system 1 according to an embodiment of the present invention will be described using FIG. 1.

The temporary housing complex design system 1 uses a virtual model to design a temporary housing complex including temporary housing. More specifically, the temporary housing complex design system 1 performs a layout plan for facilities in a temporary housing complex (hereinafter also referred to as "temporary housing layout plan"). In this embodiment, the temporary housing complex design system 1 plans the layout of temporary housing using a BIM model. Temporary housing is housing provided to disaster victims whose homes have been completely destroyed or burned down due to natural disasters such as earthquakes and typhoons, making it difficult for them to live there. Immediately after the disaster, victims live in evacuation centers, but if they are unable to secure housing on their own, they gradually move to temporary housing, which is safer and easier to maintain privacy than evacuation centers.

There are two types of temporary housing: emergency temporary housing and self-help temporary housing, but in this embodiment, the temporary housing complex design system 1 mainly plans the layout of emergency temporary housing. Emergency temporary housing includes 6 types (1DK type, equivalent to 6 tsubo) for single persons, 9 types (2DK type, equivalent to 9 tsubo) for small families, and 12 types (3DK type, equivalent to 12 tsubo) for large families. be. In the temporary housing layout plan, the ratio of 1DK type dwelling units, 2DK type dwelling units, and 3DK type dwelling units is determined in advance.

The temporary housing complex design system 1 determines the layout of facilities in a temporary housing complex in a temporary housing layout plan. The facilities include residential units, parking lots, highways, and other facilities. Other facilities include assembly halls, water tanks, septic tanks, and garbage storage areas. In the layout plan for temporary housing, the ratio between the number of dwelling units (number of dwelling units) and the number of parking lots (number of parking lots) (hereinafter referred to as "residential ratio") is determined in advance. In principle, the residential ratio is set to the number of dwelling units: the number of parking lots = 1:1, but it can also be set to any ratio.

The temporary housing complex design system 1 mainly includes a user terminal 10 and a shared server 20.

The user terminal 10 is a terminal used by a user (designer) when designing a layout plan for temporary housing. As the user terminal 10, a personal computer or the like can be used. The user terminal 10 can design a layout plan for temporary housing by arranging the BIM model of each facility in the layout plan for temporary housing in the BIM model representing the site. A plurality of user terminals 10 are provided. In FIG. 1, three user terminals 10 are shown. Details of the user terminal 10 will be described later.

The shared server 20 is connected to each user terminal 10 via a network N. The network N includes a public network such as the Internet, a wireless network such as a mobile phone network, a LAN (Local Area Network), and the like. The shared server 20 stores BIM models and various information.

Access to the shared server 20 requires access authority, and only user terminals 10 to which access authority has been granted can access the shared server 20 and share various data stored in the shared server 20. For example, a BIM model is stored in the shared server 20 at each design stage, and the user terminal 10 to which access authority is granted accesses the shared server 20 and uses the BIM model stored in the shared server 20 as its own. A BIM model can be imported into the user terminal 10 or a BIM model created on the own user terminal 10 can be uploaded to the shared server 20.

The configuration of the user terminal 10 will be described below using FIG. 2. The user terminal 10 includes a communication section 11, an operation input section 12, a calculation section 13, and a display section 14.

The communication unit 11 is a part that communicates with the shared server 20. The communication unit 11 can transmit a BIM model created on the user terminal 10 to the shared server 20, and can receive a BIM model stored on the shared server 20.

The operation input section 12 is a section for inputting various information through user operations. As the operation input unit 12, a keyboard, a mouse, etc. are used. The user can design a layout plan of temporary housing using the BIM model via the operation input unit 12. Specifically, the user can arrange and move the BIM model of each facility, input data, etc. via the operation input unit 12.

The calculation unit 13 is a part that performs various calculations. The calculation unit 13 can put the user terminal 10 into a state where a BIM model can be created by starting application software for BIM model design.

The calculation unit 13 has a storage unit that stores various data. The BIM model and various information read from the shared server 20 via the communication unit 11 are stored in the storage unit. The BIM model created by the user terminal 10 is stored in the storage unit. A temporary housing layout planning program is stored in the storage unit. The calculation unit 13 reads out the temporary housing layout planning program and executes various processes to be described later.

The display unit 14 displays images. The display unit 14 can display a BIM model. As the display section 14, a display device such as a liquid crystal display is used.

Below, the procedure for planning the layout of temporary housing will be explained using FIGS. 3 to 5. In addition, in the drawings used below, the number of dwelling units and the number of parking lots are not necessarily accurately illustrated.

The details will be described later, but in the temporary housing layout plan, optimization of the location of area boundaries that satisfy the resident ratio (hereinafter referred to as "boundary line optimization") and areas where facilities can be placed (hereinafter referred to as " Two types of optimization are performed: optimizing the positions of residential units and parking lots within the "possible placement area" (hereinafter referred to as "location optimization"). Specifically, steps 1 to 3 shown in FIGS. 3 to 5 are performed. Note that "boundary line optimization" corresponds to "partitioning processing" of the present invention.

In step 1 shown in FIG. 3, a layout plan that involves rough zoning of the site is performed. First, the user places two BIM parts a for area designation within the premises. Here, the "Area designation BIM part" is a BIM part (icon) for designating an area in which a facility is placed. BIM part a for area designation includes BIM part a1 for designating residential unit area for specifying the area where the residential unit is located (hereinafter referred to as "dwelling unit area"), and area where the parking lot is located (hereinafter referred to as "parking unit area"). A BIM part a2 for specifying a parking lot area is included for specifying a parking lot area.

The area designation BIM part a is placed within the premises by the user operating the operation input unit 12. The user places the dwelling unit area designation BIM part a1 at the approximate position where the user wants to arrange the dwelling unit, and places the parking lot area designation BIM part a2 at the approximate position where he wants to arrange the parking lot. Alternatively, the area specifying BIM part a may be automatically placed. In this case, the user moves the automatically placed BIM part a1 for specifying the residential unit area to the approximate position where the residential unit is to be placed, and moves the automatically placed BIM part a2 for specifying the parking lot area You can move it to the approximate position you want to place it.

When the program is executed with BIM part a1 for housing unit area designation and BIM part a2 for parking area designation placed, "boundary line optimization" is performed to roughly define the housing unit area and parking area. A layout plan with zoning (area designation) is presented. In the layout plan, the residential unit area and the parking lot area are separated by an area boundary e (more specifically, the main road d, which will be described later), and a BIM model of the residential unit (hereinafter referred to as "dwelling unit b") is placed in the residential unit area. A BIM model of a parking lot (hereinafter referred to as "parking lot c") is placed in the parking lot area. Note that the area boundary line e shown in FIGS. 3, 4, etc. is not actually displayed on the layout diagram, but is set on the program.

Then, a BIM model of a highway (hereinafter referred to as "arterial road d") is placed at a predetermined position. More specifically, the main road d1 is arranged between the residential unit area and the parking lot area (on the area boundary line e). The area ratio between the residential unit area and the parking lot area is set to an area ratio that satisfies the resident residence ratio. Furthermore, within the residential unit area, the main road d2 is arranged so that the width of the residential unit area (width in the longitudinal direction of the residential building) does not exceed 50 m. Moreover, in the dwelling unit area, in the dwelling unit b, 1DK type dwelling units, 2DK type dwelling units, and 3DK type dwelling units are arranged at a predetermined ratio.

By performing step 1 in this way, the information necessary for the layout plan is reflected in the layout drawing at once.

In step 2 shown in FIG. 4, a layout plan with detailed zoning taking into consideration the location of the main road is performed. Specifically, the user first sets the main road d (d1, d2) placed in step 1 as a locked main road. Here, there are two types of arterial roads used in the layout plan: arterial roads that are automatically arranged each time the program is executed, and locked arterial roads that are manually arranged by the user. A locked main road is a main road that cannot be automatically changed (locked) by a program, and the shape of the area where the area can be placed can be specified. Note that all arterial roads d may be locked at the time they are placed, regardless of whether they are placed automatically by program execution or manually by the user. Furthermore, the user can delete unnecessary trunk road d. Further, the user can also replace the main road d with a BIM model of a boundary line (hereinafter referred to as a "boundary line h") that divides the layout possible area.

The user can add the main road d (for example, the main road d3) to a desired position in the layout drawing created in step 1. Next, the user places the housing unit area designation BIM part a1 and/or the parking lot area designation BIM part a2 in each possible layout area divided by the main roads d1, d2, d3, etc. Alternatively, the BIM part a1 for housing unit area designation and/or the BIM part a2 for parking lot area designation may be automatically placed in each divided placeable area; in this case, the user can It is possible to move, delete, add, etc. the BIM part a1 for housing unit area designation and/or the BIM part a2 for parking lot area designation within the possible area as appropriate. Further, the user can also place the boundary line h in the placement possible area (in FIG. 4, the right dwelling unit area).

When the program is executed with BIM part a1 for housing unit area designation and/or BIM part a2 for parking lot area designation placed, "boundary line optimization" or "placement optimization" is performed in each placeable area. ” will be held. More specifically, when both the housing unit area designation BIM part a1 and the parking lot area designation BIM part a2 are placed in the placeable area, "boundary line optimization" is performed. On the other hand, if either one of the BIM parts a1 for specifying a residential unit area or the BIM parts a2 for specifying a parking lot area is placed in the placeable area, "placement optimization" is performed. Further, if neither the residential unit area designation BIM part a1 nor the parking lot area designation BIM part a2 is placed in the layout possible area, the layout possible area becomes a vacant lot. Note that "border line optimization" is effective only for one placeable area, and optimizes the position of one area boundary line e each time it is executed.

When "placement optimization" is performed in the placeable area where either BIM part a1 for housing unit area designation or BIM part a2 for parking lot area designation is placed, more housing units b or The position of dwelling unit b or parking lot c is optimized so that parking lot c is arranged. On the other hand, when "boundary line optimization" is performed in the placeable area where both the BIM part a1 for housing unit area designation and the BIM part a2 for parking lot area designation are located, the trunk line placed on the area boundary line e The arrangable area is further divided into a residential unit area and a parking lot area by the road d.

By performing step 2 in this way, a layout plan (layout plan) optimized according to the number of types of area designating BIM parts a in each placeable area is presented.

In step 3 shown in FIG. 5, the layout plan is finalized. Specifically, in the layout drawing created in step 2, the user changes all arterial roads to locked arterial roads, and places one area designation BIM part a in each placeable area. By executing the program in this state, the placement positions of dwelling unit b and parking lot c are optimized within all placement possible areas.

The layout drawing can be completed by combining the above three steps as necessary. More specifically, first, two area designation BIM parts a are placed, and the site is divided into two. The BIM part a for area designation is placed again in the divided arrangable area, and the arrangable area is divided in stages. Then, the layout plan can be completed by optimizing the layout of the housing units b and the parking lot c within the divided layout possible areas. Further, in each of steps 1 to 3, by executing the program with the user's operation as an initial condition, the user and the temporary housing complex design system 1 can interactively create the layout plan.

Below, the processing flow of the temporary housing layout planning program will be explained using FIGS. 6 and 7. The flows shown in FIGS. 6 and 7 are started with the fully automatic plan layout created by the program being read. Further, the flows shown in FIGS. 6 and 7 are repeatedly executed until stopped by the user.

The fully automatic layout plan includes a BIM model showing the site shape and a BIM model of roads facing the site. The location of the entrance and exit is determined based on the width of the road facing the site.

First, in step S5, the calculation unit 13 deletes the facilities placed in the placement possible area. Thereby, it is possible to prevent a facility newly placed through the process described below from overlapping with a previously placed facility. After performing the processing in step S5, the calculation unit 13 moves to step S6.

In step S6, the calculation unit 13 acquires parameter information. Here, "parameter information" is various information regarding the arrangement of temporary housing. The calculation unit 13 acquires parameter information by reading data stored in the shared server 20.

The parameter information includes initial conditions regarding the layout plan. The initial conditions include predetermined layout planning rules such as resident ratio. In the layout planning rules, various rules are defined for each category such as residential units, main roads, parking lots, garbage storage areas, assembly halls, and other categories. For example, a target value for the ratio of the number of dwelling unit types (for example, 6 types: 9 types: 12 types = 1:2:1) is determined. Note that the ratio of the number of dwelling unit types can be changed to an arbitrary ratio by the user according to the layout plan. Additionally, the distance from the main road to the entrance of each residential unit is stipulated to be within 50 meters. Additionally, it is stipulated that the number of parking lots must be equal to the number of housing units. In addition, various rules have been established.

The user can now place the area designation BIM part a in the placeable area. The placement area is an area surrounded by the main road d, the site boundary line (line representing the external shape of the site), and the like. The user places one BIM part a1 for housing unit area designation at the approximate location where the user desires to place the housing unit, and places one BIM part a2 for parking area designation at the approximate location where the user desires the parking lot layout. be able to. Alternatively, the area specifying BIM part a may be automatically placed in the layout diagram of the fully automated plan. In this case, the user moves the automatically placed BIM part a1 for specifying the residential unit area to the approximate position where the residential unit is to be placed, and moves the automatically placed BIM part a2 for specifying the parking lot area You can move it to the approximate position you want to place it.

In this manner, in the layout diagram, the BIM part a1 for specifying the dwelling unit area and the BIM part a2 for specifying the parking lot area are arranged in the arrangable area. After performing the processing in step S6, the calculation unit 13 moves to step S7.

In step S7, the calculation unit 13 determines whether there is an open space creation area. In the layout diagram, the layout possible area where the area designation BIM part a is not placed is a vacant lot. In addition, areas where residential units or parking lots cannot be placed (such as green areas) will be left vacant. Note that information on the locations of areas where residential units and parking lots cannot be placed is included in the BIM model that shows the site shape in the fully automatic layout plan. Alternatively, by arranging the boundary line h, the user can also set an area (area desired to be a vacant lot) where no residential unit or parking lot can be placed. The calculation unit 13 makes this determination based on whether there is a placeable area where the area designating BIM part a is not placed and a place where a dwelling unit or a parking lot cannot be placed. Alternatively, the area designation BIM part a may include a vacant land area designation BIM part for designating the area where the vacant land is to be placed, and there is a placeable area in which the vacant land area designation BIM part is placed. In this case, it may be determined that there is an open space creation area.

When the calculation unit 13 determines that there is a vacant land creation area ("YES" in step S7), the process proceeds to step S8. On the other hand, when the calculation unit 13 determines that there is no open space creation area ("NO" in step S7), the process proceeds to step S9.

In step S8, the calculation unit 13 creates a vacant land area. The calculation unit 13 sets the placeable area where the area designating BIM part a is not placed as a vacant land area. In addition, areas where residential units or parking lots cannot be placed are designated as vacant land areas. Alternatively, the calculation unit 13 sets the placeable area where the BIM part for specifying a vacant land area is placed as the vacant land area. After performing the processing in step S8, the calculation unit 13 moves to step S9.

In step S9, the calculation unit 13 determines whether or not there is a placement optimization area. Here, the "placement optimization area" refers to an area in which placement optimization should be performed among each possible placement area. The calculation unit 13 determines whether there is a placeable area in which either one of the housing unit area designation BIM part a1 or the parking lot area designation BIM part a2 is placed (in which one type of area designation BIM part a is placed). If so, it is determined that there is a placement optimization area. On the other hand, the calculation unit 13 can be arranged so that either one of the BIM parts a1 for housing unit area designation or the BIM parts a2 for parking lot area designation is arranged (one type of BIM part a for area designation is arranged). If there is no area, it is determined that there is no placement optimization area.

If the calculation unit 13 determines that there is a placement optimization area ("YES" in step S9), the process moves to step S10. On the other hand, when the calculation unit 13 determines that there is no placement optimization area ("NO" in step S9), the process moves to step S13 shown in FIG. 7.

In step S10, the calculation unit 13 determines a placement angle in placement optimization. Specifically, as shown in FIG. 8, the calculation unit 13 calculates the length of the side L1 (or L3) in contact with the lock main road d4 of the optimization area, and the length of the side L2 in contact with the main road d5 on the area boundary line e. (or L4). Then, the calculation unit 13 arranges the dwelling unit b and the parking lot c so that they are lined up along the longer side of both. In the example shown in FIG. 8, in the dwelling unit area, since L1>L2, the dwelling units b are arranged so as to line up along the direction of L1. In the parking lot area, since L4>L3, the parking lots c are arranged along the direction of L4. When the optimization area does not touch the lock highway d4, the housing units b and the parking lot c are arranged along the direction in which the side on the area boundary line e that touches the highway d5 extends. When the optimization area does not touch the main road d5 on the area boundary e, the housing units b and the parking lot c are arranged along the direction in which the sides that touch the lock main road d4 extend. Alternatively, the housing units b and the parking lot c may be arranged in a line perpendicular to the direction in which the main road d5 on the area boundary line e extends.

After performing the processing in step S10, the calculation unit 13 moves to step S11.

In step S11, the calculation unit 13 performs placement optimization using a genetic algorithm (GA). Specifically, as shown in FIG. 9, the calculation unit 13 calculates the vertical deviation vr of the residential building with respect to the residential building placement reference line passing through the base point (center) of the residential unit area as a design variable, and the number of residential units arranged. is set as the evaluation function to maximize the evaluation value. In addition, the calculation unit 13 sets the vertical deviation xp, yp of the parking lot with respect to the parking lot layout reference line passing through the base point of the parking lot area as a design variable, the number of parking lots arranged as an evaluation function, and sets an evaluation value. Aim to maximize.

After performing the processing in step S11, the calculation unit 13 moves to step S12.

In step S12, the calculation unit 13 calculates the arrangement coordinates of the dwelling unit b and the parking lot c. After performing the processing in step S12, the calculation unit 13 moves to step S13 shown in FIG.

In step S13, the calculation unit 13 determines whether there is a boundary line optimization area. Here, the "boundary line optimization area" refers to an area in which boundary line optimization should be performed among each placement possible area. The calculation unit 13 determines that there is a boundary line optimization area when there is an arrangement possible area in which both the BIM part a1 for specifying a dwelling unit area and the BIM part a2 for specifying a parking lot area are arranged. On the other hand, the calculation unit 13 determines that there is no boundary line optimization area if there is no placeable area in which both the BIM part a1 for specifying a dwelling unit area and the BIM part a2 for specifying a parking lot area are placed.

When the calculation unit 13 determines that there is a boundary line optimization area ("YES" in step S13), the process proceeds to step S14. On the other hand, when the calculation unit 13 determines that there is no boundary line optimization area ("NO" in step S13), the process proceeds to step S18.

In step S14, the calculation unit 13 determines the arrangement angle of the area boundary line e in boundary line optimization. Specifically, as shown in FIG. 10, the calculation unit 13 calculates the direction perpendicular to the line (search axis Let it be the arrangement angle of the area boundary line e (the direction in which the area boundary line e extends). After performing the processing in step S14, the calculation unit 13 moves to step S15.

In step S15, the calculation unit 13 performs boundary line optimization using a genetic algorithm (GA). The boundary line optimization method will be described below with reference to FIG.

First, the search range of motion is determined based on the search axis X that connects the BIM part a1 for specifying the dwelling unit area and the BIM part a2 for specifying the parking lot area, and the shape of the boundary line optimization area. Then, a straight line that satisfies the resident ratio and is perpendicular to the search axis X is defined as an area boundary line e.

More specifically, among the points obtained by projecting each vertex of the boundary line optimization area onto the search axis X, the maximum point with respect to the search axis ≦k≦1). A point P on the search axis X, which is the position of the area boundary line e, is determined based on Equation 1 below.
P=kPmax+(1-k)Pmin...Formula 1

After performing the processing in step S15, the calculation unit 13 moves to step S16.

In step S16, the calculation unit 13 calculates the arrangement coordinates of the housing unit b and the parking lot c. Note that by operating the operation input unit 12, the user can move the BIM model of other facilities such as an assembly hall displayed outside the site (hereinafter referred to as "other facilities f") to a desired position within the placeable area. can be placed in When there is a dwelling unit b and a parking lot c that interfere with the facility f, the calculation unit 13 deletes (the arrangement coordinates of) the interfering dwelling unit b and the parking lot c. As a result, positions that interfere with other facilities f are excluded from the candidate positions for housing unit b and parking lot c. After performing the processing in step S16, the calculation unit 13 moves to step S17.

In step S17, the calculation unit 13 determines the arrangement angle of the other facility f. As shown in FIG. 11, when the housing unit b and/or the parking lot c is not placed within the placement area, the calculation unit 13 calculates the line segment that indicates the boundary line of the placement area where the other facility f is placed. The angle is adjusted so that the longitudinal direction of the other facility f is perpendicular to the closest line segment g. In addition, when the housing unit b or the parking lot c is arranged within the placement area, the calculation unit 13 adjusts the angle so that the direction in which the other facilities f are lined up is parallel to the direction in which the housing units b or the parking lot c are lined up. do. Note that the same angle adjustment method may be employed regardless of whether the housing unit b and/or the parking lot c are located within the arrangable area. Further, the user can set which side of the other facility f, the long side or the short side, is to be used as the reference for angle adjustment. After performing the processing in step S17, the calculation unit 13 moves to step S18.

In step S18, the calculation unit 13 arranges arterial roads. The calculation unit 13 arranges the main road d on the area boundary line e set in step S15. After performing the processing in step S18, the calculation unit 13 moves to step S19.

In step S19, the calculation unit 13 calculates the required number of other facilities and arranges the other facilities. Specifically, the calculation unit 13 calculates the required number of other facilities such as an assembly hall and a septic tank based on the arrangement rule (for example, the number of dwelling units) acquired in step S6. Then, the calculation unit 13 arranges the other facilities f in the residential area and/or the parking area according to the arrangement angle determined in step S17. After performing the processing in step S19, the calculation unit 13 moves to step S20.

In step S20, the calculation unit 13 arranges a dwelling unit b, an access road, and a parking lot c.
