Paper Title
An Eclectic Decision for Selection of Aluminium Alloy for Aerospace and Automotive Industries

Abstract
Considering the mechanical properties of the materials, selection of suitable Aluminium alloy for aerospace and automotive industries has been carried out using Multi Criteria Decision Making (MCDM) method. Different MCDM techniques, namely Analytical Hierarchical Process (AHP), Multi Objective Optimization Based on Ratio Analysis (MOORA), COPRAS have been used in this study. AHP has been used for obtaining weight factors of the different criteria�s, COPRAS and MOORA method has been used to find the best alternative of Aluminium alloy among the several other alloys considered in this study. Keywords - MCDM, AHP, MOORA, COPRAS, Aluminium Alloy
