Knowledge-based Modeling of Manufacturing Aspects in Structural Optimization Problems

In: Proceedings EngOpt 2008, 01.06.-05.06.2008, Rio de Janeiro, Brazil

Abstract:

In this paper we present a method for the multidisciplinary optimization of structures including qualitative expert knowledge. In addition to multi objective and discrete tasks, which are solved with a genetic algorithm, mainly expert knowledge and experience is available for modeling certain influences in early design stages. Fuzzy Rule Based Systems (FRBS) provide a powerful tool to model such influences via qualitative human knowledge. Based on this idea, a method for building qualitative, knowledge based models has been developed and enhanced. As an example, structural components constructed from composite aluminum profiles with embedded continuous reinforcing elements have been optimized.
