One of the commonly used methods for multi attribute decision making is analytic hierarchy process (AHP). During last two decades, the analytic hierarchy process has been successfully applied to numerous decision areas. The essence of AHP is in permitting the decision-maker to perform pair-wise comparisons of each of the factors or criteria -- one-on-one -- to derive overall priorities. These pair-wise comparisons may be stated verbally as in "Criterion A is equally, moderately more, or strongly more important than criterion B." The adjectives likely or preferable may be substituted for important. These are converted to numerical values (generally in pre-specified range like 1 to 9) in the traditional, non-fuzzy AHP approach. The AHP method may be used for such decisions as selecting a single course of action from several, for priority setting, and for resource allocation. For the single decision-event, AHP's use is based on the following assumptions, that for a significant decision, there are several courses of action (alternatives) available, from which one will be selected based on governing criteria, not all of which will be of equal weight.
