Analytic Hierarcy Process (AHP) was developed by Saaty. It is a useful method for decision making and planning for multiple-criteria problems. It has found many applications in decision theory. AHP is a theory of measurement for dealing with quantifiable and/or ., intangible criteria. Decision applications of the AHP are carried out in two phases: hierarhic design and evaluation. In the AHP a problem is structured as a hierarchy. The evaluation phase is based on the concept of paired comparisons. The elements in the level of the hierarchy are compared in the relative terms as to their importance or contribution to a given criterian that occupies the level immediately above the elements being compared. The AHP has already being successfully applied in a variety of fields. The use of the AHP has been facilitated greatly by the availability of the software package Expert Choice.
