Method and arrangement for designing a technical system

A system for designing a technical system having a predeterminable set of target functions which are dependent on parameters, comprising;

• a weighting unit to weight each individual target function with a weighting factor;
• a processor to solve an equation system having the parameters and the weighting factors as variables in a variable space, the solutions of the equation system forming operating points of a solution space in the variable space, the operating points being determined by a predictor-corrector method comprising:
• generating a first operating point by determining a predictor as a stochastic variable in the variable space;
• and
• after generating the first operating point, generating a second operating point in a corrector step;
• and
• an output unit to output the operating points for the design of the technical system.

A computer readable medium on which is stored a computer program to perform a method for designing a technical system having a predetermined set of target functions which are dependent on parameters, the method comprising:

• weighting each individual target function with a weighting factor;
• solving an equation system in a variable space to produce operating points in a solution space, the equation system having the parameters and the weighting factors as variables, the equation system being solved by a predictor-corrector method comprising:
• generating a first operating point by determining a predictor as a stochastic variable in the variable space;
• and
• after generating the first operating point, generating a second operating point in a corrector step;
• and
• using the operating points to design the technical system.
