“…This is achieved by evaluation of a set of criteria elements and sub-criteria elements through a series of pairwise comparisons (Bhyun, 2001). Also, group decision-making problems are easily formulated by the Expert Choice software package (Bhyun & Suh, 1996;Forman, Saaty, Selly, & Waldron, 1983;Lai, Trueblood, & Wong, 1999); this allows the decision-maker to derive geometric means as weights or priorities instead of using an eigenvector method. The geometric mean is an appropriate rule for combining individual judgments to obtain the group judgment for each pairwise comparison.…”
