Convergence Properties of Analytical Target Cascading

Analytical target cascading is a relatively new methodology for the design of engineering systems. Analytical target cascading deals with the issue of propagating desirable top-level product design speciŽ cations (or targets) to appropriate targets at lower levels in a consistent and efŽ cient manner. Most existing problem formulations for multilevel design often exhibit convergence difŽ culties. It is proved that the analytical target cascading process converges to a point that satisŽ es the necessary optimality conditions of the original design target problem.
