As shown in fig. 1 and fig. 2, the present invention provides a method for generating a multilevel layout of a pharmaceutical process, comprising the following steps:
collecting a product production procedure of a medical industrial process to obtain equipment requirements;
classifying and collecting required equipment to form an equipment set to be distributed, and acquiring the minimum space requirement of each different type of equipment to be distributed;

and folding and laying out the rooms to be laid out by taking the main logistics path as an axis according to the production process of the product and the list of the rooms to be laid out, and finishing the layout of the workshop according to a preset workshop layout strategy.
The space requirement mainly comprises a three-dimensional space requirement, and the space requirement comprises a three-dimensional shape, a projection area, a working part motion range, a maintenance area, a personnel operation space, a feeding and discharging mode and a production environment requirement.

And interference among the structured two-dimensional image blocks is eliminated, and the minimum space requirement of the devices to be arranged in different categories is formed.
The product manufacturing process may include a plurality of steps, and the specific values are not limited herein. When the method for acquiring the minimum required space is automatically arranged, whether the device-level space requirement is met can be judged only by checking whether the structured two-dimensional image blocks are mutually interfered or not, so that the method is favorable for judging the validity of the result. The minimum space requirement obtained can provide for the placement of subsequent equipment at the room level.
The basic properties of the pre-stored room comprise the room type, the type and the number of devices which can be arranged in the room, the placement requirements of the devices, auxiliary tools and character flow paths. The room types can be divided into three different types, such as a production room, an auxiliary room and an auxiliary room, and the arrangement of the rooms can be different according to different appearance sequences and arrangement categories of the room types. Similarly, the basic properties of the pre-stored rooms are obtained, which are ready for subsequent room arrangement and cabin-level layout.
The method includes the steps that pre-stored rooms and equipment sets to be distributed are matched, a list of the rooms to be distributed is obtained, and the equipment to be distributed is distributed in the corresponding rooms to be distributed, and the method specifically includes the following steps:
reading basic attributes of the pre-stored rooms, and matching the pre-stored rooms of the equipment to be distributed of the equipment set to be distributed one by one;
gathering matched pre-stored rooms to obtain a list of rooms to be laid;
finishing the arrangement of the devices to be distributed in the rooms to be distributed one by one;
wherein, accomplish one by one and treat the overall arrangement equipment arrangement in treating the overall arrangement room, specific step is:
stacking the structured two-dimensional blocks representing the equipment to be laid out into the room blocks representing the rooms to be laid out;
judging the adaptation condition of the structured two-dimensional image blocks and the room image blocks, and moving the positions of the structured two-dimensional image blocks according to the adaptation condition;
and after the adaptation condition of the structured two-dimensional pattern blocks and the room pattern blocks meets the preset condition, iterating the steps to complete the arrangement of the devices to be distributed in the room to be distributed.
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, which specifically comprises the following steps:
the method comprises the steps that a first structured two-dimensional graph block is arranged according to a preset position, and then a second structured two-dimensional graph block is arranged, wherein the first structured two-dimensional graph block represents a main device, and the second structured two-dimensional graph block represents an auxiliary device;
judging the interference condition between the second structured two-dimensional image blocks and the first structured two-dimensional image blocks, and if the interference condition exists, moving the current second structured two-dimensional image blocks;
the current moving direction priority expression relation of the second structured two-dimensional image block is as follows:
wherein Q is 1 For the lower right-hand corner of the room block, Q 2 Is the upper left corner orientation, Q, of the room tile 3 The upper right hand corner orientation of the room tile.
The layout of the room level mainly considers the selection of the equipment and the arrangement of the equipment in the room. The structured two-dimensional blocks representing the devices are required to move through the mutual interference of the structured two-dimensional blocks, so as to meet the preset conditions and complete the arrangement of the devices to be arranged in the room to be arranged.
As shown in fig. 3, according to the above method for adapting and moving the structured two-dimensional block, it is determined whether the current structured two-dimensional block B (i.e. the rectangle B) collides with other structured two-dimensional blocks (e.g. representing a wall or other devices). If collision occurs, the rectangle B is moved, and the priority of the movement of the rectangle B is as follows:
starting from the lower left corner where the current room can be arranged, namely the rectangle B is preferentially arranged to the '1' point (namely the right side of the rectangle A) of the arranged structured two-dimensional block A (namely the rectangle A), the structured two-dimensional block B is temporarily formed 1 (rectangle B) 1 ) In a rectangle B 1 Then, whether the image data collide with other structural two-dimensional image blocks is judged, if the image data collide with other images, the image data move to a point 2 of the rectangle A (namely above the rectangle A), and a structural two-dimensional image block B is temporarily formed 2 (rectangle B) 2 ) If the requirement is not satisfied, the rectangular image is moved to the point "3" of the rectangle a (i.e., the upper right of the rectangle a), and the point "3" of the rectangle a is set as the final fixed arrangement position of the rectangle B.
Judging the interference condition between the second structured two-dimensional image blocks and between the first structured two-dimensional image blocks specifically comprises:
respectively collecting extreme X-axis coordinates and Y-axis coordinates of the vertex positions in the current second structured two-dimensional image block and the compared structured two-dimensional image block;
judging the relationship between the extreme value X-axis coordinate and the extreme value Y-axis coordinate of the current second structured two-dimensional image block and the compared structured two-dimensional image block, wherein the relationship comprises the following relationship:
then there is an interference condition between the current second structured two-dimensional tile and the compared structured two-dimensional tile, otherwise there is no interference condition, where X a-min For the minima of the compared structured two-dimensional pattern on the X-axis of the coordinates, X a-max Maximum, Y, of a two-dimensional block in coordinate X for comparison a-min For the minimum value of the compared structured two-dimensional pattern block in the Y-axis of coordinates, Y a-max Maximum, X, of the compared structured two-dimensional pattern in the Y-axis of coordinates b-min For the current minimum value, X, of the second structured two-dimensional image block on the coordinate X axis b-max For the maximum, Y, of the current second structured two-dimensional tile on the X-axis b-min For the current minimum value of the second structured two-dimensional image block on the coordinate Y axis, Y b-max Setting the maximum value of the current second structured two-dimensional image block on the coordinate Y axis;
and traversing all the second structured two-dimensional image blocks according to the layout and stacking sequence of the structured two-dimensional image blocks, and then finishing the judgment of the interference condition.
As shown in FIG. 4, the A block represents the primary device, and the B block represents the secondary device, i.e. with B as the current second structured two-dimensional block to perform the judgment of the interference situation with the already laid out A. Of course, a may also be other second structured two-dimensional blocks of the completed layout, or blocks representing walls in a room, etc. When comparing the interference between a and B, it is necessary to fully compare the relationship between the two-dimensional patterns in the XY two orientations. The arrangement of the structural patterns is generally parallel to the direction of the X axis or the Y axis, that is, a certain extreme value vertex is the minimum value of the X axis and the minimum value of the Y axis. However, the above judgment relationship 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 conclusion of judging whether to interfere with each other based on the above relationship is not influenced.
By comparing the coordinate extreme values of the upper left and the lower right of the structured two-dimensional image blocks, the interference condition judgment between the structured two-dimensional image blocks and the room image blocks and between the structured two-dimensional image blocks is realized, the result of the interference condition can be effectively and quickly given, and a basis is provided for the movement of the subsequent structured two-dimensional image blocks.
As shown in fig. 5, the folding layout of the rooms to be laid out with the main logistics path as an axis according to the list of the rooms to be laid out and the production process specifically includes:
adjusting the arrangement sequence of rooms to be distributed according to the production process of the product;
determining the room layout shape, acquiring the layout length of the rooms to be laid, and sequentially laying the rooms according to the list sequence of the rooms to be laid by taking the transverse direction as the boundary direction;
wherein the length of the rooms is aligned with the transverse boundaries to make arrangement, and the longitudinal lengths of all the rooms are aligned.
The layout taking the main physical flow path as an 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 in a shape of Chinese character 'hui' as an example, the basic layout analysis is carried out. The production of the medicine involves 8 processes, and 8 core production devices and 7 production rooms are required. According to the layout logic of the equipment level and the room level, according to the types of production equipment and auxiliary machines, various room lists (a production process room, an auxiliary machine room and an auxiliary room) including the theoretical minimum space requirement, the room environment requirement and the like are obtained firstly. Considering that the workshop layout is to be performed in a certain sequence, the platform takes the number of the room list as a layout reference, and sets the room sequence of the workshop-level layout by adjusting the positions of the room items in the list up and down. By selecting different layout types, one-dimensional room pattern blocks are folded, the square-shaped blocks are taken as an example, the square-shaped blocks are taken as X-direction boundaries to arrange rooms, after one side of the rooms are arranged, the rooms are flushed automatically due to the fact that the minimum areas of the rooms are different, and then the square-shaped one-side workshop layout is completed. And similarly, completing the layout of the workshop in the other three directions.
According to the product procedures and equipment requirements, all room lists are calculated and generated, room folding is carried out by taking a main logistics path as an axis according to the process flow sequence, so that different types of layout schemes are formed, evaluation indexes of the schemes are established by adjusting the room sequence, a self-adaptive process arrangement multi-scheme optimization technology is formed, and the rapid generation of the layout schemes is realized.
The preset workshop layout strategy specifically comprises the following steps:
presetting the width and the length of a workshop based on room layout, 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, and 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 )]A is the width value of the room arranged on the transverse boundary, i is the number of the lines of the room arranged on the transverse boundary, d is the distance between every two lines of the room, and C is the perimeter of the workshop;
iteration is carried out on the basic increment B of the length of the workshop, and if [1/4A + B/(2) n-1 ）]＞L＞[1/4+B/（2 n ）]Then iteration convergence is carried out, and the length of the workshop is determined 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, adapt the layout of the rooms 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 the minimum.
For example, setting a one-dimensional length a of the whole plant, equally dividing it into four segments, gives an initial solution: each side length is 1/4A, basic increment B appears after arrangement, and the basic increment B is set to appear on the long side of the workshop, namely the long side is equal to 1/4A + B. And (3) iterating the basic increment B, and iterating for the second time: the width is 1/4A, and the length is 1/4 of the circumference after the basic increment is added in the first arrangement, namely (1/2A + B) 1 ) And/2, carrying out second solving to obtain an increment B 2 =B 1 2/2 = B/2; and a third iteration: the width is 1/4A, and the length is 1/4 of the circumference after the increment is added for the second arrangement, namely (1/2A + B) 2 ) And/2, carrying out a third solving,out increment B 3 =B 2 /2= B/4 \ 8230a \ 8230and so on, forming an iteration increment B n . The iteration termination condition is as follows: iterate n times with the increment of B n Then, all rooms can be dropped and the iteration increment is B n+1 All rooms cannot be put down, and the calculation is considered to be converged to obtain an automatic layout optimal solution.
The preset workshop layout strategy can estimate the workshop width range in advance, and if and only if the workshop width is set within a limit range, the workshops can be geometrically arranged, so that the increment iteration of the workshop length can be performed. The width of the workshop satisfies the following relation: [ (a) 1 +…a i )+(d 1 +……d i-1 )]＜1/4A＜[C-2×(a 1 +…a i )]Per 2, for example, a rectangular-shaped layout of plants including a transit room, where the number of lines of the plant is 3, the minimum value of the width of the plant is estimated as the width of the transit room + the width of two lanes + the width of rooms on both sides, i.e., a 1 +a 2 +a 3 +d 1 +d 2 (ii) a The maximum width of the workshop is [ the perimeter of the plant-2 × (the minimum room length in the middle + the width of the aisles on both sides.)]2, i.e., [ L-2 × (a) 1 +a 2 +a 3 )]/2。
After the layout is completed, defining the area utilization rate as a scheme evaluation index. And establishing an experimental design aiming at the length of a workshop, and forming a self-adaptive process arrangement multi-scheme optimization technology aiming at improving the area utilization rate by defining the minimum and maximum lengths of a clean production area in the X direction and an experimental interval.
