A Knowledge-based Tool to Support the Design-to-cost Configuration of Industrial Products from Conceptual Design Stages
Abstract. Modern companies are characterized by a growing attention to cost optimization, market needs satisfaction, and time compression at the same time. This trend needs new optimization algorithms integrated with 3D CAD tools able to properly structure the design knowledge and support the designers in configuring the best design solution with respect to desired product performance, required manufacturing processes and production quantities. Such an approach considers cost and performance and could be integrated with also lifecycle assessment tools to promote sustainability-oriented design strategies. Indeed, in the modern industrial practice, product cost is estimated at the beginning of the design process by qualitative methods, but is deeply analyzed only at the end of the project by quantitative estimating techniques, when design changes are difficult to implement and very expensive, so that only minor corrective actions can be taken, generating a long iteration loop. Over the last 20 years, some methodologies have been defined to assess cost before product realization in order to optimize product and process design.
