Fuzzy grey AHP

Uncertainty as a universal characteristic of the real world problems is discussed in the paper. Analytic Hierarchy Process is one of the most utilized methods for supporting rational decisions. Despite of respected successes of the method, several modifications of the original Saaty's version have been introduced over time. In the paper, new approach to consideration of information uncertainty - Fuzzy Grey Analytic Hierarchy Process - is introduced. Replacing crisp values in expert comparisons with grey numbers, new ways of improving the quality and accuracy of the model, as well as consensus reaching in group and conflicting decisions are becoming possible.
