Abstract

The method was tackled with picking line for generating strip steel for the automobile industry. The initial conditions to which the tandem-type mill coupled with picking line executed using the installation is exposed. The installation receives an input in the form of human resources, energy, media, raw materials, semifinished product, etc., which is converted by the installation into output. Since the plant is a hot rolling mill, the output is in the form of hot rolled strips. The different components of the input can be assigned to the factor markets that are relevant to the real installation. The different components of the output can further be assigned to the product markets that are relevant to the real installation.

Claims

1. A method for operating an industrial installation, comprising:

using a computer system including a computer with a system memory and a plurality of modules;

identifying a plurality of technical measurement variables which co-determine a value retention of a real installation by a first module of the computer;

recording an actual status of the real installation by measuring the identified technical measurement variables, the actual status of the identified technical measurement variables being input into the computer via an inputting device;

specifying a benchmark and storing the specified benchmark in the computer;

comparing the actual status of the real installation with the specified benchmark to determine a technical measurement variable whose change in value increases the value retention of the real installation by a second module of the computer;

identifying a plurality of structural measures which increase the value retention of the real installation by changing the value of the technical measurement variable by a third module of the computer; and

carrying out the structural measures.

2. The method as claimed in claim 1, wherein the benchmark is specified by recording an actual status on an installation which is similar compared to the real installation to be assessed.

3. The method as claimed in claim 2, wherein the similar installation is an existing installation or an installation which is in a building phase.

4. The method as claimed in claim 2, wherein an installation-specific key component is recorded for specifying the benchmark.

5. The method as claimed in claim 2, wherein an installation-relevant innovation is recorded for specifying the benchmark.

6. The method as claimed in claim 1, wherein the actual status and a significant technical trend are recorded for factor markets relevant to the real installation, a product markets relevant to the real installation, and a technological environment of the real installation for specifying the benchmark.

7. The method as claimed in claim 1, wherein the method is partially carried out by an external service provider.

8. The method as claimed in claim 1, wherein the actual status of the real installation is partially determined by a software.

9. The method as claimed in claim 1, wherein steps of identifying the technical measurement variables, recording an actual status of the real installation, specifying a benchmark, and comparing the actual status of the real installation with the specified benchmark are carried out more frequently than steps of identifying the structural measures and carrying out the structural measures.

10. The method as claimed in claim 1, wherein an increase of the value retention of the real installation is quantitatively determined.

11. The method as claimed in claim 1, wherein the structural measures are carried out when the actual status of the real installation is at least as good as a setpoint status.

12. The method as claimed in claim 1, wherein the method is for operating a production facility.

13. A system for operating an industrial installation, comprising:

an identifier for identifying a plurality of technical measurement variables which co-determine a value retention of a real installation;

a recorder for recording an actual status of the real installation by measuring the identified technical measurement variables;

an inputting device for inputting a plurality of measured values relating to the identified technical measurement variables; and

a comparing device for comparing the actual status of the installation with a benchmark for determining a technical measurement variable whose change in value increases the value retention of the real installation.

14. The system as claimed in claim 13, wherein a plurality of structural measures are identified which increase the value retention of the real installation by changing the value of the determined technical measurement variable.

15. The system as claimed in claim 14, wherein an evaluation is provided by which an increase of the value retention of the real installation is quantitatively determined.

16. A non-transitory computer readable storage medium storing a computer program which executed by a computer system, performs a method for an industrial installation, the computer program

a computer sub program for recording an actual status of the real installation by measuring the identified technical measurement variables;

a computer sub program for interrogating a plurality of measured values relating to the identified technical measurement variables; and

a computer sub program for comparing the actual status of the real installation with a benchmark for determining a technical measurement variable whose change in value increases the value retention of the real installation.

17. The computer program as claimed in claim 16, wherein a plurality of structural measures are identified which increase the value retention of the real installation by changing the value of the determined technical measurement variable.

18. The computer program as claimed in claim 16, wherein an increase of the value retention of the real installation is quantitatively determined.

19. The computer program as claimed in claim 16, wherein the method is for operating a production facility.
