3D Printer Selection for Aircraft Component Manufacturing Using a Nonlinear FGM and Dependency-Considered Fuzzy VIKOR Approach

As a viable means to enhance the sustainability and competitiveness of aircraft manufacturing maintenance, three-dimensional (3D) printing has been extensively used in industry. However, due growing number suitable 3D printers often-high prices these printers, manufacturers still face many obstacles screening possible printers. In addition, dependencies between criteria make it difficult for decision makers properly assess their absolute priorities. Existing methods fail address issues. To solve this problem, study proposes nonlinear fuzzy geometric mean (FGM) dependency-considered vise kriterijumska optimizacija i kompromisno resenje (fuzzy VIKOR) approach. The first novel treatment is design nFGM method ensure that priorities assigned are correct. Subsequently, VIKOR, considered, realistic reference point defined by measuring distance from each printer proper evaluation. FGM VIKOR approach applied compare five components.
