摘要：Design concept is an important wealth-creating activity in companies and infrastructure. However, theprocess of designing is very complex. Besides, the information required during the conceptual stage is incomplete,imprecise, and fuzzy. Selection of proper materials for a diverse mechanism is one of the hardest tasks in the designand product improvements in various industrial applications. A systematic and efficient approach towards conceptualdesign and material selection is necessary in order to select the best alternative for a given engineering application. Theselection of an optimal design of product and material selection for an engineering design from among manyalternatives on the basis of many attributes is a multiple criteria decision making (MADM) problem. This paperproposes an integrated decision-making approach based on fuzzy linguistic variables and geometric mean methodintegrated with TOPSIS (technique for order performance by similarity to ideal solution) framework. The model willhelp designers and engineers to reach a consensus on design and materials selection for a specific application.Verification of the model is demonstrated with two example problems from the literature and results are compared withother models. Two real life problems are cited in order to demonstrate and validate the effectiveness and flexibility ofthe model.
