The material is one of the main important factors that should be considered in the design. The right material selection allows the design, on which is studied, to show the best performance. For this reason, this study aims to determine the best material for countermeasure flare systems with multi-criteria decision-making (MCDM) methods. In our study, a MCDM method called best worst based simple additive weighting (BWSAW) is proposed for material selection problem. AHP, SAW, TOPSIS, ELECTRE and BWSAW MCDM methods are also used. Cost, tensile strength, melt point, thermal conductivity, density, and thermal expansion have been taken into consideration as criteria and titanium diboride, alumina (95), chromium, silicium carbide, carbon fiber, and stainless steel as material alternatives. Carbon fiber is the best material for the AHP, SAW and BWSAW methods while stainless steel is the best material for ELECTRE and TOPSIS method. Given all methods together, it has been decided that the best material to be used for the countermeasure flare system is carbon fiber. This proposed MCDM method can be used by decision makers for all multi criteria decision making problems for future works. This study is intended at analysing the problem of the material selection of the dispenser systems used in the production of Countermeasures Dispenser Systems. In this research, a hybrid MCDM technique based on the combination of the BWM and SAW is utilized to solve the problem of selecting suitable material of the countermeasures dispenser systems in the literature.
