New solutions to a multi-objective benchmark problem of induction heating: an application of computational biogeography and evolutionary algorithms

In induction heating the design of the inductor implies the solution of coupled
electromagnetic and thermal fields, along with the use of optimal design procedures to
identify the best possible device or process. The benchmark model proposed, a graphite
disk heated by means of induction, is optimized using different optimization algorithms.
The design aim requires to achieve a prescribed and uniform temperature distribution in
the workpiece maximizing the system efficiency.
