I am preparing my master thesis. After finishing the literature review I found that all the existing literature always uses one method, which is choice modelling. My thesis is about how to analyze the preference of individuals by studying and analyzing the importance of attributes.
I already know that I need to use Multiple-criteria decision-making (MCDM) in my thesis to analyze the importance of attributes. Can I say that the contribution of my thesis is using the different method? That is, using MCDM compared to the methods in the existing literature? I really can not compare these two methods as they are based on totally different assumption and technique.
