step S202, obtaining each set of paving parameter values of the building parts, wherein any set of paving parameter values comprises: the size parameters of the shaping and laying unit and the size parameter values of the size parameters.

In one embodiment, the building components are building elements and components required for construction with relatively independent functions, such as external wall panels, thermal insulation walls, prefabricated panels, superposed beams, prefabricated staircases, superposed floor panels, and the like. The laying can comprise at least one of building and laying of the building parts, and the building parts are laid by adopting a series of laying units, so that the building parts can be built to achieve the building effect, and the surface of the building parts can also be laid to achieve the decoration effect.

In one embodiment, the building component is laid using a series of laying units, and the laying unit of the building component may include: the device comprises a shaping laying unit, a non-shaping laying unit and a decoration laying unit. Specifically, a paving unit that does not require cutting is referred to as a shaping paving unit, a paving unit that requires cutting is referred to as a non-shaping paving unit, the non-shaping paving unit can be cut by the shaping paving unit, a paving unit for decoration is referred to as a decoration paving unit, and the decoration paving unit is paved only in an outer contour edge area of a building component.

Specifically, the shaping paving unit can be a whole brick, the non-shaping paving unit can be a non-whole brick, and the decorative paving unit can be a wave brick.

In one embodiment, since the shaping and laying unit is a necessary laying unit of the building component, when each set of laying parameter values of the building component is acquired, any set of laying parameter values includes: the size parameters of the shaping and laying unit and the size parameter values of the size parameters. When the shaping and laying unit is rectangular, the dimension parameters may be the length and width of the shaping and laying unit, that is, the dimension parameter values are the corresponding values of the length and width of the shaping and laying unit. When the shaping and laying unit is a non-rectangular polygon or a circle, the dimensional parameters may be parameters related to the size of the shaping and laying unit, such as the diameter, radius, and side length of the shaping and laying unit. For convenience of description, the shaping and laying unit is exemplified as a rectangle in the embodiment of the present application. When it is determined that the laying unit of the building component includes the decoration type laying unit, the arbitrary set of laying parameter values further includes: a dimensional parameter of the decor-type laying unit, and a dimensional parameter value of the dimensional parameter. When the distance between any two profiling paving units is preset, any set of paving parameter values further comprises: the distance between any two profiling units.

And step S204, respectively generating an initial paving scheme corresponding to each group of paving parameter values based on each group of paving parameter values.

In one embodiment, a paving scheme corresponding to each set of paving parameter values, referred to as an initial paving scheme, may be generated according to a preset paving scheme generation algorithm and based on each set of paving parameter values, and the generation manner of the initial paving scheme corresponding to each set of paving parameter values is the same. Specifically, a corresponding initial paving scheme is generated each time based on a set of paving parameter values, and then an initial paving scheme corresponding to each set of paving parameter values is generated to obtain an initial paving scheme set, so that each initial paving scheme is optimized subsequently to obtain an optimal final paving scheme.

In one embodiment, the initial laying scheme of the building component can be used to determine the positions, the number and the sizes of the integer laying units and the non-integer laying units contained in the initial laying scheme. The non-integer laying unit can be obtained by cutting the integer laying unit, so that the number of the to-be-cut integer laying units of the non-integer laying unit obtained by cutting needs to be further calculated and determined. When the laying unit of the building component includes the decoration type laying unit, the position, the number, and the size of the decoration type laying unit included in the initial laying unit can also be determined by the initial laying scheme of the building component.

Step S206, calculating evaluation parameters corresponding to each initial paving scheme, wherein the evaluation parameters comprise: number of profiling laying units.

In one embodiment, each initial paving pattern may be evaluated to determine whether the initial paving pattern is an optimal final paving pattern. Specifically, the evaluation parameters corresponding to each initial paving scheme are calculated, and the evaluation parameters may include: number of profiling units. The number of the shaping paving units is the number of the shaping paving units contained in the initial paving parameters, and the number of the shaping paving units to be cut of the non-shaping paving units obtained by cutting.

And S208, optimizing each initial laying scheme according to the evaluation parameters and the preset evaluation standard to obtain a final laying scheme of the building parts.

In one embodiment, after the evaluation parameters corresponding to each initial paving scheme are obtained through calculation, each initial paving scheme may be evaluated and optimized according to preset evaluation criteria. Wherein each initial paving plan can be optimized using a genetic algorithm. Specifically, the genetic algorithm is a method for searching for an optimal solution by simulating a natural evolution process, and an optimal laying scheme of the building component, that is, a final laying scheme, can be obtained by performing a series of evolutions, such as selection, intersection and variation operations, on each initial laying scheme.

In one embodiment, after obtaining the final laying scheme of the building part, the method further includes: and drawing a building component laying layout diagram corresponding to the final laying scheme. In the building component laying layout diagram, the laying units can be numbered and marked with dimensions. In addition, a laying unit list corresponding to the laying arrangement diagram of the building parts can be manufactured, and the size, the type and the number of the laying units are marked, so that the building parts can be produced or cut in a factory.

In the method for designing the laying scheme of the building parts, each set of laying parameter values of the building parts is obtained, and any set of laying parameter values comprises the following steps: all the dimension parameters of the shaping and laying unit and the dimension parameter values of all the dimension parameters; respectively generating an initial paving scheme corresponding to each group of paving parameter values based on each group of paving parameter values; calculating evaluation parameters corresponding to each initial paving scheme, wherein the evaluation parameters comprise: the number of shaping and laying units; and optimizing each initial laying scheme according to the evaluation parameters and the preset evaluation standard to obtain the final laying scheme of the building parts. By adopting the method of the embodiment, different initial laying schemes can be obtained by obtaining each set of laying parameter values of the building parts, the efficiency of manually designing the laying schemes is effectively improved, the final laying scheme meeting the preset evaluation standard is obtained by optimizing each initial laying scheme, and the optimal laying scheme can be ensured to be obtained, so that the laying cost is effectively saved, and the laying efficiency of the building parts is improved.

In one embodiment, step S202 obtains each set of paving parameter values for the building component, including:

step S302, determining each dimension parameter of the shaping and laying unit and the dimension range of each dimension parameter.

In one embodiment, the laying unit of the building component comprises a shaping laying unit, and each size parameter of the shaping laying unit and the size range of each size parameter can be determined according to the specification model of the shaping laying unit. When the integer laying unit is rectangular, each size parameter can be the length and the width of the integer laying unit, and the size range can be the value range of the length and the value range of the width.

And S304, randomly taking values of all the size parameters in the size range corresponding to the size parameters respectively to obtain all the groups of paving parameter values of the building parts.

In one embodiment, each dimension parameter of the integrated laying unit is randomly valued in a dimension range corresponding to the dimension parameter, that is, when each dimension parameter is the length and the width of the integrated laying unit, a permutation and combination mode is adopted, one length value is randomly selected in the length value range, one width value is randomly selected in the width value range, and each set of laying parameter values of the building component is obtained. For example, if there are 3 length values in the length range and 3 width values in the width range of the integer paving unit, the obtained paving parameter values of the building components include 9 sets.

In one embodiment, step S204 generates an initial paving scheme corresponding to each set of paving parameter values based on each set of paving parameter values, respectively, including:

step S402, determining an area to be paved corresponding to the building component and a preset reference position.

In one embodiment, when the initial laying scheme corresponding to each set of laying parameter values is generated, an area of the building component to be laid, also referred to as an area to be laid, needs to be determined first. Since the decorative type laying unit is only laid in the outer contour edge area of the building component, when the area to be laid corresponding to the building component is determined, whether the laying unit comprises the decorative type laying unit or not needs to be determined.

In one embodiment, when the laying unit of the building component comprises the decoration type laying unit, the outer contour of the building component is translated inwards by a preset distance by taking the central position of the building component as a reference, and a laying area corresponding to the translated outer contour of the building component is determined as an area to be laid. Wherein the preset distance is a dimension parameter value of a dimension parameter of the decorative type laying unit. Specifically, the size parameter value different from that of the integer paving unit among the size parameter values of the size parameters of the decoration type paving unit is used as the preset distance. For example, when the length of the decorative type laying unit is the same as the length of the shaping laying unit and the width of the decorative type laying unit is not the same as the width of the shaping laying unit, the width of the decorative type laying unit is taken as the preset distance. When the laying unit of the building component does not comprise the decoration type laying unit, the laying area corresponding to the outer contour of the building component is directly determined as the area to be laid.

In one embodiment, the preset reference position is a reference position preset in the area to be paved. Specifically, the center position of the shaping and laying unit may be set in advance, or the position of one of the vertices of the shaping and laying unit may be set.

Step S404, dividing the area to be paved along a first direction by taking a preset reference position as a reference according to a first interval to obtain a first division result, wherein the first division result comprises each first sub-area, the first interval is a size parameter value of a first side length, and the preset reference position is located between two adjacent first sub-areas.

In one embodiment, when the integer paving unit is rectangular, the dimensional parameters of the integer paving unit include a length and a width, also referred to as a first side length and a second side length, respectively. The first side length and the second side length are respectively one of the size parameters of the length and the width, and the size parameters represented by the first side length and the second side length are different, that is, when the first side length is the length, the second side length is the width, and when the first side length is the width, the second side length is the length.

In one embodiment, the area to be paved is divided along a first direction at a first interval by taking a preset reference position as a reference, and a first division result is obtained. Wherein, when dividing the area to be paved, the lines for dividing are parallel to each other. Specifically, the first distance is a size parameter value of a first side length, the first direction is a horizontal axis direction of a three-dimensional coordinate system of a plane where the building component is located, the first side length is taken as the length of the shaping and laying unit as an example, that is, starting from a preset reference position, an area to be laid is divided along the horizontal axis direction according to the length value of the shaping and laying unit, and a first division result is obtained. The first division result comprises first sub-areas, and the preset reference position is located between every two adjacent first sub-areas.

And step S406, dividing the region to be paved along a second direction according to a second distance by taking the preset reference position as a reference to obtain a second division result, wherein the second division result comprises each second sub-region, the second distance is a size parameter value of a second side length, and the preset reference position is located between two adjacent second sub-regions.

In one embodiment, the area to be paved is divided along the second direction at the second interval by taking the preset reference position as a reference, and a second division result is obtained. Wherein, when dividing the area to be paved, the lines for dividing are parallel to each other. Specifically, the second distance is a dimension parameter value of a second side length, the second direction is a longitudinal axis direction of a three-dimensional coordinate system of a plane where the building component is located, the second side length is taken as a width of the shaping and laying unit as an example, that is, starting from a preset reference position, an area to be laid is divided along the longitudinal axis direction according to a width value of the shaping and laying unit, and a second division result is obtained. And the second division result comprises each second sub-area, and the preset reference position is positioned between two adjacent second sub-areas.

In one embodiment, when the distance between any two shaping paving units is preset, in order to ensure the paving aesthetics, the first distance is the sum of the size parameter value of the first side length and the distance, and the second distance is the sum of the size parameter value of the second side length and the distance.

Step S408 is to generate initial paving plans corresponding to the respective sets of paving parameter values based on the first division result and the second division result, respectively.

In one embodiment, the first division result and the second division result are integrated, and the initial paving scheme corresponding to each set of paving parameter values is determined according to the integrated division result of the region to be paved.

In one embodiment, step S408 generates an initial paving scheme corresponding to each set of paving parameter values based on the first division result and the second division result, respectively, and includes:

step S502, obtaining each coincident sub-region of each first sub-region and each second sub-region based on the first division result and the second division result.

In one embodiment, since the first division result includes each first sub-region and the second division result includes each second sub-region, the first division result and the second division result are integrated to establish a planar grid, and each coincident sub-region of each first sub-region and each second sub-region is obtained. Wherein one coinciding sub-area may represent one paving unit. Depending on the shape of the coinciding sub-areas, it may be determined whether the coinciding sub-areas are represented as integer laying units or non-integer laying units.

Step S504, the position, the number and the size of each overlapped subarea are determined, and initial laying schemes corresponding to each set of laying parameter values are respectively generated.

In one embodiment, the position, number and size of the respective coinciding sub-areas, i.e. the position, number and size of the integer laying unit and the non-integer laying unit, are determined, respectively, generating an initial laying plan corresponding to the respective set of laying parameter values.

In one embodiment, step S206 calculates evaluation parameters corresponding to each initial paving plan, including:

step S602, acquiring the number and size of non-integer paving units included in each initial paving scheme and the number of integer paving units included in each initial paving scheme.

In one embodiment, the number of the shaped paving units included in the initial paving scheme can be directly determined, and since the non-shaped paving units included in the initial paving scheme need to be cut by the shaped paving units, the number of the shaped paving units to be cut, from which the non-shaped paving units are cut, needs to be calculated. Specifically, the number and size of non-integer paving units included in each initial paving plan, and the number of integer paving units included in each initial paving plan are acquired respectively.

And step S604, calculating and cutting the number of the to-be-cut and trimmed laying units of the non-trimmed laying units based on the number and the size of the non-trimmed laying units.

In one embodiment, the number of trimmed paving units to be trimmed of non-trimmed paving units resulting from trimming may be calculated by a bin packing problem algorithm. The classical packing problem is that a certain amount of articles are put into boxes with the same capacity, the sum of the sizes of the articles in each box does not exceed the capacity of the boxes, the number of the used boxes is minimized, namely, the quantity of the integral laying units to be cut with the minimum quantity can be calculated as much as possible by a packing problem algorithm based on the determined quantity and size of the non-integral laying units contained in each initial laying scheme, and laying cost is effectively saved.

Step S606, calculating the number of the shaping and paving units required by each initial paving scheme according to the number of the shaping and paving units and the number of the shaping and paving units to be cut, wherein the evaluation parameters comprise: the number of integer paving units required for the initial paving scheme.

In one embodiment, the number of the shaping and laying units required by each initial laying scheme is the sum of the number of the shaping and laying units and the number of the shaping and laying units to be cut. The method comprises the following steps of taking the number of shaping and paving units required by an initial paving scheme as an evaluation parameter, and evaluating and optimizing each initial scheme to be paved.

In one embodiment, step S208 optimizes each initial laying scheme according to the evaluation parameters and the preset evaluation criteria to obtain a final laying scheme for the building component, including:

step S702, determining whether each initial paving scheme meets the optimization ending condition according to the evaluation parameters corresponding to each initial paving scheme and the preset evaluation standard.

In one embodiment, the preset evaluation criterion is a criterion for presetting an optimal paving scheme, and specifically includes: the number of the shaping laying units is the largest, the number of the non-shaping laying units is the smallest, the distance between any two shaping laying units is the smallest, and the number of the shaping laying units to be cut of the non-shaping laying units obtained by cutting is the smallest. Specifically, the preset evaluation criteria are evaluated according to the evaluation parameters corresponding to the initial paving schemes. The method comprises the steps of calculating the degree of congestion corresponding to each initial laying scheme by adopting a genetic algorithm according to a preset evaluation standard to obtain a congestion degree calculation result, and determining whether each initial laying scheme meets an optimization ending condition or not according to the congestion degree calculation result. Or performing non-domination sequencing on each initial scheme to obtain a non-domination sequencing result, and determining whether each initial laying scheme meets the optimization ending condition or not based on the non-domination sequencing result.

In one embodiment, the optimization end condition is an optimization end condition for multi-objective optimization by a preset genetic algorithm. Specifically, the optimization ending condition may be a set optimization iteration number, a set congestion degree threshold, or a congestion degree of the optimal initial paving scheme no longer changes.

And step S704, when the optimization ending condition is not met, optimizing each initial laying scheme to obtain the optimized initial laying scheme of the building part, and returning to the step of determining whether each initial laying scheme meets the optimization ending condition until the optimization ending condition is met.

In one embodiment, when it is determined that each initial laying scheme does not satisfy the optimization end condition, each initial laying scheme is optimized based on a genetic algorithm to obtain an initial laying scheme of the optimized building component, and the step S702 is returned to determine whether each initial laying scheme satisfies the optimization end condition until the optimization end condition is satisfied.

And step S706, determining the initial laying scheme meeting the preset evaluation standard as the final laying scheme of the building parts when the optimization finishing condition is met.

In one embodiment, when each initial laying scheme is determined to meet the optimization end condition, one initial laying scheme meeting the preset evaluation criteria is determined as the final laying scheme of the building component by combining the preset evaluation criteria.

In one embodiment, step S704 optimizes each initial laying scheme when the optimization end condition is not satisfied, and obtains an initial laying scheme of the optimized building component, including:

and S802, evolving each initial paving scheme to obtain each evolved initial paving scheme, wherein the number of each evolved initial paving scheme is greater than that of each initial paving scheme.
