Saw Index

The Simple Additive Weighting (SAW) method is a structured approach used to evaluate and rank a set of alternatives based on multiple, often conflicting, criteria. It is characterized by its simplicity and ease of interpretation, making it a go-to method for researchers and managers who need to synthesize various data points into a single actionable score.

John Kramer once said, "The numbers are clean." He was right. The Saw Index is clean, cold, and terrifyingly logical.

The Simple Additive Weighting (SAW) method is a multi-criteria decision-making technique widely used in healthcare administration. It works by assigning a weight to each criterion (e.g., punctuality, responsibility, teamwork) and then calculating a total score for each alternative (e.g., each employee). The alternative with the highest total score is ranked the best. Healthcare centers and hospitals use the SAW method to evaluate staff performance, make hiring decisions, and allocate resources.

Environmental scientists frequently use the SAW index to map Groundwater Potential (GWP) zones and classify surface water quality . By layering geographic parameters like soil type, slope, rainfall, and land use, the resulting SAW index separates highly polluted zones from clean water resources.
