Obtaining weights from interval comparison matrices

Analytic hierarchy process (AHP) is a useful method in multi-criteria decision making problems. Crisp comparison matrices produce crisp weight estimates. It is logical for an interval or fuzzy comparison matrix to give an interval or fuzzy weight estimate. In this paper, we proposed a new and simple method to generate interval weight estimate from an interval comparison matrix, which can be either consistent or inconsistent. It is based on correct normalization methods. Numerical results are calculated to show the quality and quantity of the proposed and compare with other existing procedures. The obtained results show that the proposed method are simple, efective, without solving any mathematical programming and complicated algebraic operation.
