Selection of Gear Materials Using MCDM-TOPSIS Approach

Sunil Kumar Tiwari, Sarang Pande


Materials selection are a key issue in the optimal design of the industrial product. Material selection is a difficult and subtle task because of an immense number of different available materials. Increasing demand for gears in the different field of applications has forced manufacturers to design and develop gears which compete in the global market and satisfy the user requirements as well as environmental conditions. Various attributes of gear materials which are generally considered by a consumer are density, tensile strength, shear modulus, yield strength, brinell hardness and cost so as to provide consumers desired value and satisfaction level. Currently, numerous gear materials are available in the market having their own merits and demerits, appropriate methodology for selection is essential. An MCDM-TOPSIS Approach has been used in the paper to select the appropriate material for gear manufacturing considering several criteria.
