The results of all these
comparisons will be combined to give the best alternative with the highest priority. The goal and criteria are one
comparison group with the goal as the parent and the criteria as the children. The criteria will be pairwise compared
with respect to the Goal for importance. Each criterion connected to the alternatives forms a comparison group with
that criterion as the parent and the alternative as children [11, 12, 13]. The alternatives will be pairwise compared
with respect to the criterion for preference as shown in Fig.2 given below.
