Abstract: In this paper, traction system design in carried out with a
multilevel optimization technique called Target Cascading. This methodology is
based on a hierarchical breaking down and allows solving a problem with
multiple parallel optimizations. The large-scale system design problem is
usually decomposed into several linked optimization subproblems according to
project organization structure. Target Cascading gives a new approach to
formulate and to solve the complex system design optimization problem in the
electrical field. The problem formulation is more suitable to this kind of
problem than conventional methods because it is closer to a work organisation
of design engineers.
