AHP-General Idea Develop an hierarchy of decision criteria and define the alternative courses of actions. ■ It requires a step by step process of pairwise comparisons of options against each of the objectives. Then the objectives themselves must be compared and weighted. Each objective can have a collection of sub-objectives on which this process can be carried out,from where the hierarchy'originates.
