Index: Saw

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

Generally indicates a better alternative (closer to the ideal solution).

In the realm of Multi-Criteria Decision-Making (MCDM), the index method is one of the most popular, intuitive, and widely applied techniques for selecting the best alternative among several options, especially when dealing with complex, multi-faceted criteria. saw index

Used in GIS-based systems to determine the best locations for new facilities, warehouses, or environmental restoration sites.

The SAW method is exceptionally versatile and is used across various fields: Studies have shown that the SAW model can

Understanding the SAW Index: Simple Additive Weighting in Decision-Making

The normalized score for each criterion is multiplied by its weight, and all weighted scores are summed to produce the final SAW index for each alternative. Step-by-Step Methodology to Calculate SAW The SAW method can be broken down into five distinct steps. 1. Identify Alternatives and Criteria Define the set of alternatives ( ) and the criteria ( ) used to evaluate them. 2. Create the Decision Matrix Used in GIS-based systems to determine the best

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

Each criterion is assigned a weight representing its relative importance, with the sum of all weights equaling 1.
