- the invention relates to a method and an arrangement for designing a technical system.
- the object of the invention is to provide a method and an arrangement for designing a technical system, at least in the context of multi-target optimization a parameter vector is determined, which is a solution with sufficient good with regard to the design of the technical system.
- each target function preferably of a predetermined set of n parameters
- a parameter vector x can be influenced.
- Each target function is also provided with a weight parameter.
- parameters for the design of the technical system are determined. These parameters preferably represent a so-called efficient parameter vector of the technical system.
- the technical system is optionally designed, which results in the described determination of the parameter vector with n parameters, or a parameter vector of an already implemented system is designed by determining a parameter vector for the existing system with regard to the given target functions, which parameter vector has a high Guaranteed good of the system.
- a parameter vector (as an operating parameter of the system or a design parameter for the system) cannot be implemented, which is why an alternative solution is indispensable.
- the invention enables an automatic generation of a number of alternative solutions, the ede of which represents an efficient implementation with regard to the setting or design of the technical system or the technical system.

- One embodiment of the invention is that a numerical method, for example the Newton method, is used to solve the systems of equations.
- the technical system is implemented or set on the basis of the determined parameters. This has the advantage that the parameters m of a parameter vector, which was determined by means of the invention, identify a stable operating point and the setting of the system to this operating point ensures a safe state of the system.
- parameters of the target function can be operating parameters or design parameters.
- Operating parameters identify possible adjustable sizes, while design parameters in particular identify physical dimensions of the technical system and cannot be adapted or changed at all or only with great effort during operation.

- a global target function is specified in accordance with equation (1), the technical system having a predetermined set of k target functions and each target function being able to be influenced by a set of n parameters (collectively m a parameter vector x);
- Parameter vector (stationary parameter values for this parameter vector) is determined by determining an approximation parameter vector x using equation (4), this approximation parameter vector x as a starting value for a method for solving the non-linear
- This arrangement is particularly suitable for carrying out the method according to the invention or a further development described above.

- Fig.l shows a block diagram with steps to design a technical system.
- the technical system comprises a predetermined set of k target functions, one target function representing the costs for the technical system, another target function representing the efficiency of the technical system.
- Each objective function comprises a set of n parameters, these parameters being combined as a parameter vector.
- the parameters (also: parameter values) are, in particular, operating parameters or design parameters.
- a first (parameter) vector x s is determined by solving equation (2).
- a numerical method for non-linear optimization for example the BFGS variant of the quasi-Newton method (cf. [1]), is used in particular for this solution.
- an approximation value (approximation parameter vector) x is determined.
- This approximate value x serves as the starting value for a method for solving a non-linear system of equations according to equation (5)

An entry is made using a mouse MAS or a keyboard TAST.
- the processor unit PRZE also has a data bus BUS, which ensures the connection of a memory MEM, the processor CPU and the input / output interface IOS.
- additional components can be connected to the data bus BUS, for example additional memory, data storage (hard disk) or scanner.
