	It takes a large sum of time for the decision makers to select alternatives. In the time where the DMs are selecting alternatives the project might have changed where a alternative is added or deleted, which then results in that the DMs have to make the entire process over again. In complex projects like govermental ones where the DM is excecuting a pairwise comparison to govermental policies, when the DM have finished the process, the goverment implements a new policy. The AHP method is great tool for small projects where there arent too many criterias and alternatives.		It takes a large sum of time for the decision makers to select alternatives.
