ABSTRACT / САЖЕТАК:

Material selection is a complex multi-criteria decision-making problem, which requires a lot of knowledge and experience for successful solving. This process is significant in product development, as it represents one of the factors on whose success the success of the product itself depends. Material selection process is influenced by several factors such as thermal, mechanical, electrical, chemical, physical and technological properties as well as their price and availability. Improper material selection frequently causes both unwanted costs and premature product failure. Gear material selection problem by using MCDM approach was considered in this paper. A decision support system named MCDM Solver was used to help decision makers to solve this complex task. MCDM Solver was used in decision‐making process to rank materials for gear manufacturing with respect to several criteria. Based on the results the best ranked material is carburized steel, while nitride steel and surface hardened alloy steel was the second and third best choice respectively for gear design. The ranking results are also compared with those of past researchers.
