A method for calculating an optimized trajectory via a simulation program and an optimization routine, wherein the trajectory is provided via the simulation program and adapted to boundary conditions, where the method includes a loop in which, as individual steps, a first trajectory is provided, a further trajectory, and the adaptation of the further trajectory is modified based on the boundary conditions, such that the optimized trajectory is a trajectory which has been provided based on an extremal or predetermined parameter, where the optimized trajectory is provided after the calculation by a control device for moving a holder for a component, and where at least one component and the production machine are displayed in a 3D display.
