Abstract:
An automobile bumper is a component, which contributes to vehicle crashworthiness during front or rear collisions. Selection of the most suitable material for the bumper involves the study of a large number of factors, such as, mechanical, physical, and chemical properties as well as formability and cost. This selection process can be regarded as a multi-criteria decision making (MCDM) problem, which may be solved applying mathematical computations. The use of recently developed MCDM methods for selecting the most preferred material for the bumper is described in this study. Obtained results revealed unanimously that high density polyethylene (HDPE) is the most suitable material for this application.

Key words:
Automobile’s bumper, multi-criteria decision making, material selection
