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...
Gogus and Boucher (1998) developed a method for calculating the inconsistency ratio of fuzzy pairwise comparison matrices, which its steps are given as follows. STEP 1: Transform a triangular fuzzy matrix into two independent matrices. At...
The steps of the fuzzy AHP technique using Chang's method can be given as follows: 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 The...
The literature of data envelopment analysis (DEA) encompasses many surveys, yet all either emphasize methodologies or do not make a distinction between methodological and application papers. This study is the first literature survey that focuses on DEA applications,...
dea application The value of data envelopment analysis (DEA) lies in its capability to relatively evaluate the individual efficiency or performance of a decision making unit (DMU) within a target group of interest that operates in a certain application domain such as...
