The minimum space requirements obtained can provide for the layout of the subsequent devices at the room level.
The basic attributes of the pre-stored rooms include the types of rooms, the types and the number of devices which can be laid out in the rooms, the requirements for placing the devices, auxiliary tools and people logistics paths. The room types can be classified into three different types, such as a production room, an auxiliary room, and the arrangement of the rooms may be different according to the different appearance sequences and arrangement categories of the room types.

Judging the adaptation condition of the structured two-dimensional image block and the room image block, and moving the position of the structured two-dimensional image block according to the adaptation condition, wherein the method specifically comprises the following steps:
the method comprises the steps of arranging a first structured two-dimensional image block according to a preset position, and then arranging a second structured two-dimensional image block, wherein the first structured two-dimensional image block represents a main device, and the second structured two-dimensional image block represents an auxiliary device;
judging interference conditions between the second structured two-dimensional image blocks and the first structured two-dimensional image blocks, and if the interference conditions exist, moving the current second structured two-dimensional image blocks;
wherein the current movement azimuth priority of the second structured two-dimensional tile represents the relationship:
wherein Q is 1 For the lower right corner orientation of the room pattern, Q 2 For the upper left corner orientation of the room pattern, Q 3 Is the upper right corner orientation of the room tile.
The layout of the room level mainly considers the selection of the devices and the placement of the devices in the room. The structured two-dimensional image blocks representing the equipment are required to be moved by checking whether the structured two-dimensional image blocks are mutually interfered or not so as to meet the preset conditions, and the arrangement of the equipment to be laid in the room to be laid is completed.
As shown in fig. 3, according to the above adaptation and movement method of the structured two-dimensional tile, it is determined whether the current structured two-dimensional tile B (i.e., rectangle B) collides with another structured two-dimensional tile (e.g., representing a wall or other device). If collision occurs, moving the rectangle B, wherein the moving priority of the rectangle B is as follows:
starting from the lower left corner of the current room, i.e. rectangle B is preferentially arranged to the 1 point (i.e. the right side of rectangle A) of the arranged structured two-dimensional block A (i.e. rectangle A), and the structured two-dimensional block B is temporarily formed 1 (rectangle B) 1 ) In rectangle B 1 Then judging whether collision occurs with other structured two-dimensional image blocks, if collision occurs with other patterns, the image blocks move to the 2 point of the rectangle A (namely, the upper part of the rectangle A) to temporarily form the structured two-dimensional image block B 2 (rectangle B) 2 ) If the requirement is not satisfied, the moving device moves to the point '3' of the rectangle A (namely, the upper right side of the rectangle A), and the point '3' of the rectangle A is taken as the final fixed arrangement position of the rectangle B.
Judging interference conditions between the second structural two-dimensional image blocks and between the first structural two-dimensional image blocks, specifically comprising:
respectively acquiring extreme X-axis and Y-axis coordinates of vertex positions in the current second structured two-dimensional block and the compared structured two-dimensional block;
judging the relation between the extreme X-axis and Y-axis coordinates of the current second structured two-dimensional block and the compared structured two-dimensional block, wherein the relation exists as follows:
then there is an interference condition with the current second structured two-dimensional tile and the compared structured two-dimensional tile, otherwise there is no interference condition, wherein X a-min Minimum value in coordinate X-axis for a compared structured two-dimensional tile, X a-max Maximum value in coordinate X-axis for the compared structured two-dimensional tiles, Y a-min Minimum value in coordinate Y-axis for the compared structured two-dimensional tiles, Y a-max Maximum value in coordinate Y-axis, X for the compared structured two-dimensional tiles b-min For the minimum value of the current second structured two-dimensional block in the X axis of the coordinate, X b-max Maximum value of current second structured two-dimensional block in X axis of coordinates, Y b-min For the minimum value of the current second structured two-dimensional block on the coordinate Y axis, Y b-max The maximum value of the current second structured two-dimensional block on the Y axis of the coordinate is obtained;
and traversing all second structured two-dimensional blocks according to the layout stacking sequence of the structured two-dimensional blocks, and then completing the judgment of interference conditions.
As shown in fig. 4, the a block represents the primary device, and the B block represents the secondary device, i.e., the B is taken as the current second structured two-dimensional block to interfere with the a of the completed layout. Of course, a may be another second structured two-dimensional tile for completing the layout, or may be a tile representing a wall in a room, etc. When comparing the interference between A and B, it is necessary to sufficiently compare the relationship between the two dimensions of the two-dimensional image block in XY. The structured tiles are generally arranged parallel to the X-axis or Y-axis direction, i.e., the vertex of a certain extremum is both the X-axis minimum and the Y-axis minimum. However, the above relationship of judgment is not particularly limited, and even if the extreme points of the X axis and the Y axis are not at the same vertex, the judgment of whether to interfere or not based on the above relationship is not affected.
The interference condition judgment between the structured two-dimensional image block and the room image block and between the structured two-dimensional image blocks is realized by comparing the coordinate extremum of the upper left and the lower right of the structured two-dimensional image block, so that the interference condition result can be effectively and rapidly given, and the basis is provided for the movement of the follow-up structured two-dimensional image block.
As shown in fig. 5, according to the product production process and the list of rooms to be laid out, the rooms to be laid out are folded and laid out by taking the main logistics path as an axis, which specifically includes:
according to the production procedure of the product, the arrangement sequence of rooms to be laid out is adjusted;

wherein, the longitudinal lengths of the rooms are aligned with the transverse boundaries and are leveled.
The layout taking the main stream path as the axis comprises an L shape, a return shape, a straight shape and the like. Taking the production medicine as a common tablet and the layout logic ' Chinese character ' Hui ' as an example, the basic layout analysis is carried out. The production of the medicine involves 8 procedures, 8 core production devices and 7 production rooms are needed in total. According to the layout logic of the equipment level and the room level, various types of room lists (production process rooms, auxiliary machines and auxiliary rooms) including theoretical minimum space requirements, room environment requirements and the like are firstly obtained according to the models of production equipment and auxiliary machines. Considering that the workshop layout is to be performed in a certain order subsequently, the platform sets the room order of the workshop-level layout by adjusting the positions of the room entries in the list up and down with the number of the room list as a layout reference. By selecting different layout types, the one-dimensional room image blocks are folded, taking the shape of the Chinese character 'Hui' as an example, taking the shape of the Chinese character 'Hui' as an X-direction boundary for carrying out room arrangement, and after one side of the room is arranged, the phenomenon of different lengths of the Y direction can occur due to different minimum areas of the rooms, so that the room is automatically flushed, and the layout of the workshop on one side of the Chinese character 'Hui' is completed. And similarly, the workshop layout in the other three directions is completed.
According to the product procedures and equipment requirements, calculating and generating all room lists, folding rooms by taking a main material flow path as an axis according to the process flow sequence, so as to form different types of layout schemes, and establishing evaluation indexes of the schemes by adjusting the room sequence to form a self-adaptive process arrangement multi-scheme optimization technology, thereby realizing the rapid generation of the layout schemes.
The preset workshop layout strategy comprises the following specific steps:
based on the room layout, presetting the width and the length of a workshop, wherein the width of the workshop is 1/4A, and the length of the workshop is 1/4A+B;
fixing the width of the workshop, judging the width of the workshop, wherein the width of the workshop meets the following relation: [ (a) 1 +…a i )+(d 1 +……d i-1 )]＜1/4A＜[C-2×(a 1 +…a i )]Wherein a is a room width value of the transverse boundary arrangement, i is a room row number of the transverse boundary arrangement, d is a space between the room rows, and C is a perimeter of the workshop;
iterating the basic increment B of the workshop length, if [ 1/4A+B/(2) n-1 ）]＞L＞[1/4+B/（2 n ）]The iteration converges to determine the length of the workshop to be 1/4A+B/(2) n-1 ) Where n is the number of iterations and L is the maximum length of the room layout.
The preset workshop layout strategy can fix the width of the workshop, and the layout of the rooms is adapted by continuously adjusting the length of the workshop until the workshop can be enough for arranging enough rooms, and the area of the workshop is minimum.
For example, setting the one-dimensional length a of the whole plant, dividing it equally into four segments, can obtain the initial solution: each side has the length of 1/4A, a basic increment B appears after arrangement, and the basic increment B is arranged on the long side of the workshop, namely, the long side is equal to 1/4A+B. Iterating the basic increment B, and iterating for the second time: the width is 1/4A, the length is 1/4 of the circumference after adding basic increment for the first time of arrangement, namely (1/2A+B) 1 ) And/2, performing a second solving to obtain an increment B 2 =B 1 2=b/2; third iteration: the width is 1/4A, the length is 1/4 of the circumference after the increment is added in the second arrangement, namely (1/2A+B) 2 ) And/2, performing a third solution to obtain an increment B 3 =B 2 2=b/4 … … and so on, forming an iteration increment B n . The iteration termination conditions are: iterating n times, wherein the iteration increment is B n When all rooms can be put down, and the iteration increment is B n+1 When all rooms cannot be put down, the calculation is considered to be converged, and the automatic layout optimal solution is obtained.
The preset workshop layout strategy can be used for estimating the workshop width range in advance, and if and only if the workshop width is set in the limit range, the workshop can be geometrically arranged, and incremental iteration of the workshop length can be carried out. The width of the plant satisfies the following relationship: [ (a) 1 +…a i )+(d 1 +……d i-1 )]＜1/4A＜[C-2×(a 1 +…a i )]2 to contain a transfer roomFor example, the workshop is arranged in a shape like a Chinese character 'Hui', the number of lines in the workshop is 3, and the minimum value of the width of the workshop is estimated to be the width of the middle, the width of two channels and the width of rooms on two sides, namely a 1 +a 2 +a 3 +d 1 +d 2 The method comprises the steps of carrying out a first treatment on the surface of the The maximum width of the workshop is [ circumference of factory building-2× (minimum room length in the middle+width of passageway on two sides)]2, i.e. [ L-2× (a) 1 +a 2 +a 3 )]/2。
After the layout is completed, "area utilization" is defined as a plan evaluation index. And an experimental design aiming at the workshop length is established, and a self-adaptive process arrangement multi-scheme optimization technology aiming at improving the area utilization rate is formed by defining the minimum and maximum lengths of the clean production area in the X direction and experimental intervals.
