Abstract: How to select materials with reason and meet the requirements is an important process in product’s design,and it is important for improving the quality and the market competition of products.To meet the requirements of multi-restriction and multi-objective optimization in the material choice progress,an integrated intelligent system based on Artificial Neural Network（ANN） and Genetic Algorithms（GAs） was proposed.ANN was used for system modeling,which searched fitness function for GAs.And GAs was applied in multi-objective optimization.Based on all above,a computer aided intelligent material-choice system was presented.It was validated through the test,and it provide a reasonable guidance for users in materials selection.

Key words: intelligent material-choice system, multi-objective optimization, Artificial Neural Network, Genetic Algorithms
