To Understand the Methodology of Analytical Hierarchy Process (AHP) Through its Application in the Selection of Automobiles

Very often in engineering and commercial applications, we are faced with the problem of making the optimal decision from amongst the available alternatives which are based on several different criteria. To add to the complications, these criteria are expressed in different units. Also, some of the criteria cannot be expressed in quantitative terms. However, the AHP methodology helps us to overcome these problems and enables us to arrive at the optimal decision. In this paper, we illustrate the use of this methodology in taking a decision on the selection of best car for the family based on multiple criteria including sub-criteria in some cases. Initially, the sub-criteria are evaluated taking two at a time and their relative priorities are assigned based on their importance to the main criterion.
