The objective of our research tasks is to homogeneous the velocity distribution on the outlet side of the die, through the control and the optimization of the geometrical parameters and operating conditions. An optimization procedure, based on the response surface method, was proposed. All the functions are written in an explicit form by using the either diffuse approximation or the Kriging interpolation. Due to the presence of the nonlinear constraints, an iterative algorithm of type SQP, was used. To find the global optimum with precision and at lower cost an auto-adaptive research space is adopted. The results of three other applications highlight the interest of the optimization of the geometrical and operational parameters of the extru...
