STEP 1: Draw the hierarchical chart

STEP 2: Define fuzzy numbers for performing the pair-wise comparisons

STEP 3: Create the pair-wise comparison matrix using fuzzy numbers

STEP 4: Calculate for each row of the pair-wise comparison matrix

STEP 5: Compute the magnitude of with respect to each other

STEP 6: Compute the weight of the criteria and alternatives in the pair-wise comparison matrix

STEP 7: Calculate the final weight vector
