PROBLEM TO BE SOLVED: To minimize product development time by quickly identifying which existing material best matches a desired set of properties. SOLUTION: A material selection system and method for selecting a material that matches the desired set of properties most strictly is provided. Users may input property values (10) they desire in a material, which properties they want searched and scored (20 and 30), the acceptable values of those properties (40), and a priority value (50) for each property. Preliminary matching materials may be retrieved from a materials database (70), and an index value for each property value may be calculated (80). One of four fuzzy membership functions may then be utilized to calculate a scored property value for each property of each material (90). The scored property value may then be weighted (100) to account for the priority value assigned to each property. The results may then be sorted in descending order based on their overall match scores (120), and outputted to a user so the best matching material(s) is readily identifiable by the user.
