In a method for designing a technical system, a technical system is
modeled by a predetermined quantity of target functions depending on
parameters, each individual target function being weighted with a
weighting factor. The method solves a system of equations comprising the
parameters and the weighting factors as variables in a variable space,
solutions of the system of equations forming working points of a solution
space in the variable space. The working points are determined by a
predictor-corrector method, according to which a predictor produced by a
stochastic variable is determined in the variable space, from a first
working point, and a second working point is then determined in a
correcting step. The determined working points are used to design the
technical system. The method can be used to redesign, modify or adapt an
already existing technical system.
