A body armor design selection is a MCDM approach in nature as it deals with different criteria or attributes to find it out best one. It is a strategic decision approach to our VIT students’ product design course project. For that purpose, we have made five alternative body armor designs in different sizes and applications. A Criteria Importance through Inter criteria Correlation method, a MCDM technique will be helpful to identify this problem. We have considered here 6 attributes such as less weight, comfort, process perspective, price, most shelf life and flexible perspective. The students interviewed and surveyed to identify the most importance criteria taken into consideration for selecting their best design among the five body armors.
