Fuzzy AHP extension of AHP was developed to solve imprecise hierarchical problems. The lack of consistency in decision making can lead to inconsistent conclusions. It is difficult to ensure a consistent pair-wise comparison. This paper proposes a consistency approximation and ranking method for fuzzy judgment matrix. This method gives an analysis for parameters in the transformation formulas of the fuzzy consistent judgment matrix and to set up a linear goal programming model to obtain the ranking vector of alternative and the consistent fuzzy judgment matrix for approximating to the decision maker's preference information. Finally, a numerical example is used to illustrate the proposed method
