Abstract. Complex dynamics of global markets force companies to adopt new ways in order to increase competitiveness. The multidisciplinary approach has proven to be crucial in making products always more competitive and successful. When tackling issues increasingly complex, the designer is obliged to consider simultaneously multiple perspectives in order to determine the optimal solution. Engineers are asked to achieve the right compromise in terms of product features to optimize the product performances, manufacturing cost and manufacturing lead-time. This optimization process is often manual and does not allow a comprehensive exploration of what the main problem is, leading to the choice of solutions that are potentially suboptimal. Furthermore, objective functions often cannot be expressed through the use of simple algebraic relations which necessarily bring up the need of using specific software for their evaluation. Moreover, a step-by-step approach to identify the right combination of design criteria is a time and cost consuming process. Therefore, the automation of the optimization process, based on the integration of CAD, CAE and Design for Cost (DfC) software, is essential to increase the product quality and to facilitate and accelerate the identification of the optimal configuration.

Keywords. Design for Cost, CAD parameterization, Multi-Objective Optimization.
