Abstract
Due to the high level of nonlinearity, few applications have been reported in the
area of multi-objective optimization of metal forming process parameters. This
paper presents a nonlinear multi-objective optimization model for metal
forming process parameters. The developed nonlinear goal programming multi-
objective optimization model allows different priority level for each process
objective. The resulting nonlinear optimization problem is solved using zero
order unconstrained optimization techniques. This reduces the effort required to
model the metal forming process problem since linearization and gradients are
not required. The optimum solution can also be achieved from any starting
point, since feasibility conditions are not needed. The application and efficiency
of the developed model is studied using deep drawing test cases wit
