Abstract

The invention concerns a computerized method for producing a two-dimensional plant model of a modular production plant for producing a chemical product, the production plant comprising at least two processing modules, which can be connected to one another for production purposes, and at least one processing container in which the processing modules can be accommodated at least partially, as required, wherein, for each processing container, a common two-dimensional container model ( 2 ) of its the base area ( 3 ) and of the base area ( 3 ) of a container environment at least partially surrounding the processing container and of predefinable size being generated, wherein, for each processing module, a two-dimensional module model ( 5 ) of its base area is generated, wherein the container model ( 2 ) and the module model ( 5 ) are divided into fields ( 1, 4 ) which are of equal size and preferably square, there being assigned to each field ( 4 ) of a module model ( 5 ) a module property concerning the occupancy of the particular field ( 4 ) by a functional device, of the particular processing module, disposed above the base area portion, of the particular processing module, corresponding to this field ( 4 ), by an operations room which is disposed above the base area portion, of the particular processing module, corresponding to this field ( 4 ) and assigned to the processing module, or by a material outlet of the processing module which is disposed above the base area portion, of the particular processing module, corresponding to this field ( 4 ), there being assigned to each field ( 1 ) of the container model ( 2 ) an occupancy property concerning the (im)possibility of the particular field ( 1 ) being occupied by a module property, the module model ( 5 ) being disposed in the container model ( 2 ) taking account of the module properties and occupancy properties.

First claim

The invention claimed is:

1. A computerized method for producing a two-dimensional plant model of a modular production plant for producing a chemical product, wherein the production plant has at least two process modules, which can be connected to one another for production purposes, and at least one process container in which the process modules can be at least partially accommodated as intended,
wherein, for each process container, a common two-dimensional container model of its base area and of the base area of a container environment at least partially surrounding the process container and of a predefinable size is generated,
wherein, for each process module, a two-dimensional module model of its base area is generated,
wherein the container model and the module models are divided into grid fields which are of the same size,
wherein each grid field of a module model is assigned a module property concerning the occupancy of the respective grid field by a functional device of the respective process module, which functional device is arranged above that section of the base area of the respective process module which corresponds to this grid field, by an operations room which is allocated to the process module and is arranged above that section of the base area of the respective process module which corresponds to this grid field, or by a material output of the process module, which output is arranged above that section of the base area of the respective process module which corresponds to this grid field,
wherein each grid field of the container model is assigned an occupancy property concerning the possibility or impossibility of the respective grid field being occupied by a module property,
wherein the module models are arranged in the container model taking into account the module properties and the occupancy properties.

2. The computerized method according to claim 1 , wherein the occupancy properties are selected from a group comprising at least one of the following properties: cannot be occupied, can be occupied only by an operations room, can be occupied only by a functional device, not occupied, occupied by an operations room and occupied by a functional device.

3. The computerized method according to claim 2 , wherein the module models are arranged in the container model taking into account at least one of the further conditions selected from the following group:
a grid field of a module model assigned an operations room allocated to the respective process module should be arranged in a grid field of the container model which has already been occupied by a grid field of a further module model assigned an operations room allocated to the respective further process module;
a grid field of a module model assigned a functional device of the respective process module should be arranged in a grid field of the container model assigned the occupancy property “can be occupied only by a functional device” or “preferably occupied by a functional device”;
a grid field of a module model assigned an operations room allocated to the respective process module should be arranged in a grid field of the container model assigned the occupancy property “can be occupied only by an operations room” or “preferably occupied by an operations room”;
a grid field of a module model assigned a functional device of the respective process module should be arranged in a grid field of the container model which has already been occupied by a grid field of a further module model assigned a material output of the respective further process module; and
a grid field of a module model assigned a material output of the respective process module should be arranged in a grid field of the container model which has already been occupied by a grid field of a further module model assigned a functional device of the respective further process module.

4. The computerized method according claim 1 , wherein each grid field of the container model is assigned one of the properties “inside the container” or “outside the container”.

5. The computerized method according to claim 1 , wherein each grid field of the container model is assigned an absolute integer coordinate pair (x abs , y abs ) wherein the origin of the underlying absolute coordinate system is arranged inside the base area of the process container.

6. The computerized method according to claim 5 , wherein each module model is assigned an orientation relative to the absolute coordinate system.

7. The computerized method according to claim 1 , wherein each grid field of a module model is assigned a relative integer coordinate pair (x rel , Y rel ), wherein the origin of the underlying relative coordinate system is arranged inside the base area of the process module.

8. The computerized method according to claim 7 , wherein each module model is assigned a position in the absolute coordinate system, which position is defined by the position of the origin of the respective relative coordinate system inside the absolute coordinate system.

9. The computerized method according to claim 1 , wherein all possible connection variants between grid fields of different module models, which are each assigned a functional device, are determined, wherein each connection variant is weighted with a value from a predefinable range of values.

10. The computerized method according to claim 9 , wherein connection variants weighted with a negative value result in the distance between grid fields associated with these connection variants being maximized, and in that connection variants weighted with a positive value result in the distance between grid fields associated with these connection variants being minimized.

11. The computerized method according to claim 9 , wherein, in the case of a plurality of connection variants with comparable weightings with positive values, that connection variant which is weighted with the smallest positive value is selected.

12. The computerized method according to claim 9 , wherein the predefinable range of values is from −100 to 100.

13. The computerized method according to claim 1 , wherein the module models are arranged in the container model taking into account at least one of the further conditions selected from the following group:
