The right selection of material is a crucial part when designing any new product. In the automobile industry, material selection is even more important because of increasing emphasis on lightweight design. There are many different material-selection methodologies, but in most cases, these are only evaluation models that evaluate the material already selected. In this diploma, we prepared an expert model, which is based on multi-attribute decision-making model. Expert model proposes a group of materials that is as close as possible to the product requirements. With such an expert model, we help a designer with proposed material to think about materials with excellent mechanical properties, although this material is usually not used in the automotive industry.
