While designing a new type of engineering material one has to search for some existing materials which suits design requirement and then he can try to produce new kind of engineering material. This selection process itself is tedious as he has to select few numbers of materials out of a set of lakhs of materials. Therefore in this paper a model is proposed to select a particular material which suits the user requirement, by using some similarity/distance measuring functionalities. Here thirteen different types of similarity/distance measuring functionalities are examined. Performance Index Measure(PIM) is calculated to verify the relative performance of the selected material with the target material. Then all the results are normalised for the purpose of analysing the results. Hence the proposed model reduces the wastage of time in selection and also avoids the haphazardly selection of the materials in materials design and manufacturing industries.
