A Multi Criteria Decision Making Methodology for Material Selection using Inner Product of Vectors

摘要

Today the variety of materials is available with each material having its own characteristics, applications, advantages, and limitations. In choosing the right material, there is not always a single definite attribute of selection and the designers and engineers have to take into account a large number of material selection attributes. The ability to select the most appropriate material for a given application is the fundamental challenges faced by the design engineer. A systematic and efficient approach to material selection approach is necessary in order to select the best alternative for a given application.A multi-criteria analysis is a popular tool to select best alternative for given applications. A new method presented in this paper (IPV method) has a different perspective. The procedure is based on an Inner Product of Vectors method considering the material selection attributes and their relative importance for the application considered.
