Brief intro about Analytic Hierarchy Process(AHP)
Analytic Hierarchy Process(AHP) is a kind of methodology to help decision making. It is used for decision scenario which we have to evaluate several choices against multiple criteria.
For such problem, we may simply subjectively set a criteria weight, and for each criteria we give a score for all options, and finally calculate a final score for all options for evaluation.
What AHP can help on such problem
AHP can help to provide a more consistent method to evaluate the criteria weight, and we can validate the consistency. And for each criteria perspective choices ranking, AHP can provide a more consistent method to rank options. And again, the consistency can be validated.
More details about how AHP works can be found on Google/Wiki if you are interested. I also found a tutorial, https://mi.boku.ac.at/ahp/ahptutorial.pdf , which talking about AHP and I think it is quite well for understanding the idea.
