WebGrey relational analysis ( GRA) was developed by Deng Julong of Huazhong University of Science and Technology. It is one of the most widely used models of grey system theory. … WebThe selection criteria are through extensive review of literature, and are evaluated based on primary data. Grey Absolute Decision Analysis (GADA) model was used to evaluate the criteria. Comparative analysis with the Simple Additive Weighting (SAW) and TOPSIS methods confirmed the soundness of the results obtained through GADA.
