Construct a matrix where rows are alternatives and columns are criteria. Each cell contains the raw performance value of an alternative for a specific criterion. 3. Normalize the Decision Matrix
Often referred to as the or scoring method , the SAW method evaluates alternatives based on their performance across various weighted criteria. Whether it is choosing a supplier, locating a facility, or selecting a investment project, the SAW index provides a transparent framework to make informed decisions. What is the SAW Index? saw index
It is clear how each criterion affects the final outcome, making it ideal for justification in public or corporate decision-making. Construct a matrix where rows are alternatives and

Used to map groundwater potential zones (GWP) in arid regions, identifying areas for maximum recharge by analyzing factors like soil texture, geology, and slope. It is also employed to assess water quality and identify highly polluted zones in river catchments.
Studies have shown that the SAW model can provide superior performance compared to other methods like the OIF index for specific scenarios like groundwater prospect mapping . Real-World Applications of SAW
