Analytical Hierarchy Process – A Comprehensive Study

Analytical Hierarchy Process – A Comprehensive Study

Introduction

Imagine a situation where you need to make choice in a complex, highly subjective scenario where there is more than one realistic option. You can think and over think or can wait until a solution is somehow circumstantially chosen for you. But, it can be said without any doubt that neither of the approaches is appropriate for this kind of situation and make you more confused than you were when you started. This kind of situations requires significant personal judgment and subjective evaluation. Under such circumstances, the options at hand need to be evaluated in a systematic and organized manner before choosing the best solution to your problem. We are rational beings and we usually like to weigh out the variables and options at our disposal for making an objective decision. But, we often face criterions which are not easy to measure. Amidst all the confusion, a Professor from the University of Pittsburg, Thomas Saaty introduced the Analytic Hierarchy Process (AHP) in 1980 for handling this particular kind of decision making.

About Analytic Hierarchy Process (AHP)

According to him, the AHP is an effective tool for simplifying complex decision making and it also helps the decision maker with setting priorities and making the best decision. The AHP helps to capture both the subjective as well as the objective aspects of a decision. According to this model, a complex decision is first reduced to a series of pair wise comparisons and then, the final result is synthesized. Moreover, the AHP brings with it a very useful technique for checking the decision consistency of decision maker’s evaluations and thus, removing any bias in the decision making process.
