Optimizing the Design of Brake Disc Using Multi-criteria Decision-making Method AHP-TOPSIS for All-terrain Vehicle

The need of transportation vehicle has become dominant in the recent few years. The braking system in the vehicle is concerned with the safety of the people travelling in it. Thus, to make a robust design of the brake disc serves as prime importance in the vehicle. Braking system consists of various components like brake disc, clutch sleeve, brake callipers etc out of which the study is focused on the design and selection of brake disc. There are numerous input parameters like material, loading condition, design models of brake disc are studied each at three levels. The experimental design was made by using the Taguchi's L9 orthogonal array to find the best optimum level of the process parameters so that they are least affected by noise factors for obtaining a robust design of parameters. Further, the analysis of variance was carried out to check the significance of the model. AHP and TOPSIS method are used to find the best combination of input parameters.
