Applied in spectral decision analysis to select the best radio channel based on metrics like throughput, handoff rate, and bandwidth. Limitations
Since criteria are measured in different units (e.g., dollars, distance, ratings), they must be normalized to a standard scale (usually 0 to 1).
It can handle a large number of alternatives and criteria. saw index
Generally indicates a better alternative (closer to the ideal solution).
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 Applied in spectral decision analysis to select the

Indicates a less desirable alternative. Core Principles
SAW assumes that the importance of a criterion is linear, which might not always reflect human decision-making behavior.
The final results are highly sensitive to the weights assigned, which can be subjective if not determined through a robust method (like AHP or Entropy). Conclusion
