Abstract: This paper is related to the use of multi-criteria decision-making (MCDM) tools for assisting material selection for aircraft parts. In this direction, decision models including analytic hierarchy process (AHP), complex proportional assessment (COPRAS), technique for order preference by similarity to ideal solution (TOPSIS), and Borda count methods were used to select the best materials for aircraft wings and nose. AHP was used to determine the criteria weights. According to the criteria weights, the rankings were obtained using AHP, COPRAS, and TOPSIS methods. Then, the final integrated rankings were obtained by Borda count method. Finally, the rankings obtained by AHP, COPRAS, and TOPSIS methods were compared to the final integrated rankings using Spearman's rank correlation coefficient.

Keywords: aircraft; material selection; analytic hierarchy process; AHP; complex proportional assessment; COPRAS; technique for order preference by similarity to ideal solution; TOPSIS; Borda count method.
