Techniques like AHP (Analytic Hierarchy Process) or TOPSIS used when an engineering solution must balance conflicting goals (e.g., maximizing strength while minimizing weight and cost).

His professor, Dr. Kalyani, had scribbled a single, terrifying note on his draft proposal: “Your sampling method is flawed. Refer to Ganesan on research methodology. Resubmit.” research+methodology+for+engineers+r+ganesan+pdf+exclusive
