The Analytic Hierarchy Process (AHP) technique, developed by Saaty (1980, 1990 and 1994), uses a process of pair-wise comparisons to determine the relative importance (and thus the priority) of alternatives in a multi-criteria decision-making process. AHP involves decomposing a complex and unstructured problem into a set of variables that are organized into a hierarchy. It enables decision makers to make choices among a number of alternatives and criteria by formulating priorities and making a series of tradeoffs. Although the AHP technique was originally developed for solving multi-criteria decision-making problems, its practicality and versatility have allowed AHP to be widely applied in many different areas—including marketing (Wind and Saaty, 1980) and accounting/auditing (Arrington et al., 1984). Zahedi (1989) using simple multi-attribute value function (Belton and Gear, 1983), multi-criteria decision analysis (Triantaphyllou et al., 1994), and data flow problem (Wang and Raz, 1991) provided a comprehensive study by using the application of AHP. In addition to this, Sato (2004) extended the use of AHP technique in measuring the human perception about multiple choice and AHP. Moreover, Wabalickis (1988) employed the AHP technique for justification of FMS. Though, AHP technique had been widely used in different areas, it has also been criticized by some authors. Dyer and Wendell (1985) and Dyer (1990) critically analyzed the limitations of AHP properties. Belton and Gear (1983) identified the shortcoming of Saaty’s method of analytic hierarchies.
